Jim has become particularly interested in the genetic basis of cancer and has spent considerable time reading published papers about oncogenes. He learned that as early as 1972 researchers suggested that mutations in proto-oncogenes caused by carcinogens can convert them to oncogenes. He asked you to answer a couple of questions about this because he did not have the biology background to totally understand. Jim learned that some cancer cells produce more growth-stimulating proteins than others. What would you give him as a plausible explanation
Answer:
Proto-oncogenes may have mutated to become oncogenes in these cells
Explanation:
Cancer cells are characterized by key properties such as an abnormally rapid rate and poor differentiation. Proto-oncogenes are genes that lead normal cells to become cancer cells when they are mutated. Many proto-oncogenes are involved in the control and progression of the cell cycle, and apoptosis (programmed cell death) pathway. Some examples of protooncogenes include 1-the Ras gene, which is required for differentiation, growth, and cell survival (mutations of this gene have been reported in pancreatic cancer, lung cancer, colon cancer and thyroid cancer), 2-the Myc gene (mutated in Burkitt's lymphoma), 3- the Her2 receptor (a receptor kinase associated with breast cancer), etc.

The term bycatch or incidental catch refers to ________. non-target species that are caught along with commercial species species harvested for industrial purposes species raised in aquaculture settings species caught as part of traditional fisheries krill and other shellfish
Answer:
The correct answer is ''non-target species that are caught along with commercial species''
Explanation:
Bycatch refers to bycatch organisms that are not targeted by the fishery. Occurs inadvertently in fishing gear, all fisheries have some unwanted bycatch. Species with little or no commercial value, juvenile stages, or discarded gravid females of the target species (s) are generally included here. These incidental catches can be marginal when fishing is carried out with selective or very substantial gear, when the gear used indiscriminately catches everything that comes along its route. In marine fisheries, it causes injury or death to mammals, birds, turtles, fish, elasmobranchs, and invertebrates.

Answer:
molecules with a polar end and a nonpolar end that can be used to disperse lipids into polar liquids such as water.
Explanation:
The process of emulsification is very important in science. An emulsifier is a substance that is used to disperse hydrophobic substances in a polar substance such as water.
An emulsifier has a hydrophillic head and a hydrophobic tail. The hydrophillic head dissolves in a polar substance such as water while the hydrophobic tail dissolves in the lipid thereby dispersing the lipid in water.
Where is amyglada located in a brain ? How does it function ?
Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.
Explanation
The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).

A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylthiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous
Answer:
The correct answer is -
A) BbTt x bbTt
B) .5^4 or 1/16 or 0.0625
Explanation:
As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.
For Branchydactylus and For tasting : man and women will be heterogeneous.
Hence,
The Genotype of man = BbTt
The Genotype of wife = bbTt
b. Answer = 0.0625
For Branchydactylus:
Bb X bb
Possible genotypes:
B b
b Bb( Brachydactylus) bb(normal)
b Bb (Brachydactylus) bb (normal)
The probability of a single child being Branchydactylus = 2/4 = 0.5
So, Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625
una persona camina durante una hora y media y corre 4 km con velocidad constante ¿cuál era su velocidad en km/h y en m/s?
La respuesta es: su velocidad es 2.66 km/h, equivalente a 0.738 m/s.
Explanation
Para conocer la velocidad de una persona que recorrió 4 km luego de caminar durante una hora y media es necesario dividir la distancia (en kilómetros) total en el tiempo (en horas). Entonces la operación sería:
4km/1,5h = 2.66 km/h.
Posteriormente, para convertir 2.66 km/h en m/s es necesario aplicar la siguiente formula
2.66 km/h *(1000 m/1 km)*(1 h/3.600 s) = 0.738 m/s.

Which of the following is not true of integrin? Question 4 options: Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix. Integrins undergo extensive conformational changes on binding to molecules on either side of the plasma membrane. Certain intracellular chemical signals can activate integrins from inside the cell, causing them to reach out and grab hold of extracellular structures. When integrin binds to the extracellular matrix, it stretches into an extended, activated state to attach to molecules on the inside of the cell.
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.

How can ecological factors influence in pond ecosystem? Discuss it with suitable examples with respect to its structural and functional aspects?
The ecological factors influence in pond ecosystem by providing the basic structure and materials that the ecosystem needed.
Oxygen, carbon dioxide, water, light and nutrients are the abiotic factors whereas the biotic components are algae, bacteria, protozoa and other organisms are the ecological factors that greatly influence the pond ecosystem. If one of the factor is missing or eliminated from the pond ecosystem the whole ecosystem will disturb and can't work properly. For example, if light is eliminated from the ecosystem, no producers can grow and ultimately death and destruction of the whole ecosystem occurs.
https://brainly.com/question/24312891
Ecological factors, such as temperature or trophic relationships between organisms, influences the characteristics of a population in a certain habitat because they make it possible for organisms to have everything they need in the environment to feed, reproduce and survive.
An ecosystem is a system that groups together different populations of animal and plant species which share all the resources available in the same environment. Interactions develop between the elements of an ecosystem, such as energy exchange, food or trophic relationships and all this makes it possible to maintain life in the ecosystem. There are many natural habitats where an ecosystem develops, such as rivers, forests, swamps, deserts, among others. However, there are also artificial habitats created by humans, such as ponds. Ponds have fresh water like lakes, but are smaller (although it is important to consider that ponds can also be formed naturally by water retained or stagnant in a depression in the ground that is usually formed by rain water). Some of the organisms in this ecosystem live in ponds all their lives, while others are transient and visit them only to reproduce and/or feed. Ponds, being habitats where animal and plant species coexist, are susceptible to the influence of environmental factors.
Ecological factors influence the life of any living organism. They can be:
Abiotic: non-living elementsSunlightTemperatureWindHumidityAtmospheric pressurePresence of metals in the soilThe pH of the water2. Biotic: living organisms
Presence of other species that can be preys, competitors, predators or parasites.We have to consider that in a pond we can find microscopic algae that use sunlight and mineral substances in the water, perform photosynthesis and then are eaten by herbivorous animals such as fish, frogs and toads (which can also eat insects as do shrews). These, in turn, are eaten by carnivorous animals, such as herons.
It must be taken into account that for life to take place in a correct and natural way, it is necessary that all the ecological factors are correct. So, the presence and quantity of ecological factors influences how the habitat develops since, for example, with the necessary and sufficient amount of sunlight, plants survive by photosynthesizing and these plants are food for herbivorous animals that in turn will be food for other carnivorous animals. This would then alter the food chain, as the population of the different species would start to decrease because it represents a series of organisms that eat each other in such a way that energy and nutrients flow from one to another.
In addition, the temperature must be adequate for vegetation to grow and for animals to survive. Therefore, it is important that the environmental factors present in the habitat are the right ones and in the right quantity, otherwise the balance of the ecosystem can be lost and thus seriously threaten the survival of the species. In this way, any factor that is altered will affect the ecosystem of the pond.

Which method would best answer his question about reaction rate and what will he find out about substance A
What is the difference between a food chain and food web
Answer:
A food chain is a sequence of organisms through which nutrients and energy pass as one organism eats another. A food chain must start with energy from the sun, have a producer (an organism that makes food by itself with energy from sun), and have at least one consumer eat and gain nutrients from another consumer or a producer. At the end of the food chain, there must be a decomposer to break down the dead animals into nutrients, which is beneficial for soil. Additionally, there must be arrows to indicate the flow of energy travelling from one organism to another. An example of a food chain would be:
sun -> roses -> caterpillar -> crows -> garter snakes -> mushrooms
Energy source: Sun
Producer: Roses
Consumer: Caterpillar
Secondary consumer: Crows
Tertiary consumer: Garter snakes
Decomposer: Mushrooms
A food web is basically an interconnection of multiple food-chains in a graphical representation to see which animal eats what and their niche (role they play in an ecological community). Here's an example of a food web (not mine, credits to creator):

Answer:
it generates NADH for use in mitochondrial ATP production
The function of Calvin cycle is to generate NADH for use in the mitochondrial ATP production in the process of cellular respiration. Thus, the correct option is A.
What is Calvin cycle?
Calvin cycle is also known as the C3 cycle or citric acid cycle. It is the cycle of chemical reactions where the carbon atom from the carbon cycle is fixed into various different molecules of sugar. It occurs in the chloroplast of the plant cell.
Calvin cycle is an important mechanism as it involves performing chemical reactions by plants to fix carbon from CO₂ into the three-carbon sugars (glyceraldehyde). Afterward, the plants and other creatures can transform these three-carbon compounds into amino acids, nucleotides, and other more complex sugars like starches. Calvin cycle generates NADH for use in the mitochondrial ATP production.
Therefore, the correct option is A.

different seeds need different cultivation. justify in 200 words.
for 18 points
Answer:
Cultivation is the process of growing crops. we need different seeds to cultivate different types of food. Similarly, different seeds need different cultivation. For eg: we grow potatoes in well-drained loam soil. But we grow rice in muddy soil. Every seed has a different way to produce food. They need different temperate or climates, different types of soil, to grow them. They have their own time or season to grow and produce food. If we try to grow plants or vegetables in the wrong season or the wrong process, then we can't get a good result. For eg: If we try to grow rice in drained soil then it will not give us a good result or if we try to grow potatoes in muddy soil we cant get our good result.
So, we can say that different seeds need different cultivation.

Answer:
B)
Explanation:
The answer is B, because as you go up in the trophic levels, energy is lost in the process.
Answer:
The best answer would be D, all of the above.
Explanation:
Option A counts since too much rats would be bad for plants since the plants will just die out, then no food for rats, so they die out, then snakes die out from not food, then eagles, you get it. If there's too much snakes, it's bad for rats and the rats die out, means the plants over populate, then no food for snakes, so they die out, etc. It's important to have such trophic system in any habitat.
Option B counts since not all energy is past down. Plants can get the most out of energy since all they do is collect it. Meanwhile animals can't since they're always on the move, meaning that energy is lost. This is why 10% of energy is lost on each level.
Option C counts since, well isn't it obvious? Look outside. You know, there's a lot of different trees, flowers, grass, etc. Now look at birds or insects. Not as much, but still pretty diverse. Then maybe look at cats or dogs. It's clear that it's less diverse. Then raptors and bears? Not very diverse, there's a few types like hawks, falcons, polar bears, but it's not very much.
So the best option would be D, all of the above.
