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):

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 statements explains the importance of carbon in cells? (Choose all that apply)
Carbon affects the function of a cell.
Carbon is a waste product for a cell.
Carbon provides structure for a cell.
Carbon maintains the proper temperature in a cell.
Carbon can easily make bonds with other atoms, allowing biomolecules like DNA and RNA, which are crucial for the development and replication that characterize life, to take on a variety of shapes and functions. Thus, option C is correct.
What is importance of carbon in cells?Carbon is an essential component for all living things. Due to its role in the production of numerous bonds and essential molecules in all living things, carbon is an important chemical.
Due to its unique chemical structure, carbon may combine with numerous other molecules to form a variety of compounds.
Because of its propensity to create stable bonds with other elements, including itself, carbon is the main component of organic molecules.
It makes up roughly 20% of an organism's weight and is necessary for them to survive, develop, and procreate.
Therefore, carbon provides structure for a cell.

Explanation:
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

The sugar in RNA is, the sugar in DNA is
deoxyribose; ribose
glucose; deoxyribose
ribose; glucose
ribose; deoxyribose
Answer:
Last choice: ribose; deoxyribose
Explanation:
Ribose (otherwise known as D-ribose) is a sugar found in RNA (ribonucleic acid). It alternates with phosphate groups to create the “backbone” of the RNA polymer.
Deoxyribose (sugar in DNA) is one of the three components of nucleotides for DNA. Each nucleotide consists of a phosphate group and a nitrogenous base: adenine, thymine, cytosine, guanine, and deoxyribose.
Glucose is a type of sugar which is a common and crucial energy source in living organisms and is often a component in various carbohydrates. Plants can create glucose by going through a process called photosynthesis, and once it's done with the process, they use the glucose (sugar) as their food for energy.

What causes an ionic bond to form between sodium and chlorine?
Answer:
The loss of an electron
Explanation:When sodium (Na) and chlorine (Cl) are combined, the sodium atoms each lose an electron, forming cations (Na+), and the chlorine atoms each gain an electron to form anions (Cl−
Answer:
"Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. ... If sodium can transfer it's "spare" electron to chlorine, both atoms will satisfy their full outer shell requirements, and an ionic bond will be formed."

Which of the following statements about cardiac muscle is true? a. Cardiac muscle is like smooth muscle, because smooth muscle has a banded appearance. b. Cardiac muscle is like smooth muscle, because it contains no bands. c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle. d. Cardiac muscle is like skeletal muscle, because skeletal muscle has involuntary contractions.
Answer:
c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.
Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.

Can anyone help with this biology?
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.

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.
