Why do you think so many people are ignorant on the topic of overpopulation and it's effects? Please answer in one paragraph (: thanks
Answer: Human overpopulation is among the most pressing environmental issues, silently aggravating the forces behind global warming, environmental pollution, habitat loss, the sixth mass extinction, intensive farming practices and the consumption of finite natural resources.
Answer:
I think they are ignorant because they don't understand what overpopulation can do to the world. Meaning overpopulation can cause less jobs for people. Less food to go around.

CELLS: Choose three membrane-bound organelles. Describe them below.
Include their shape, location, and a detailed description of their function.
Answer:Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Explanation:
Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a golgi apparatus that packages and distributes proteins. Mitochondria are the power house of the cell and provide the cell with energy.

Analysis of mitochondrial DNA can answer interesting and important questions. For which of the questions would analyzing mitochondrial DNA be futile?
Answer:
to identify the father of the individual
Explanation:
Mitochondrial DNA (mtDNA) is the circular DNA molecule found in mitochondria, which is an organelle responsible for cell respiration by converting chemical energy from foods to ATP by the process of cellular respiration. In humans, mtDNA consists of about 16,500 base pairs (bp) and encodes for 22 tRNAs, 2 rRNAs and 13 proteins. In most of the species, including humans, mtDNA is inherited from the mother (i.e., it is maternally inherited), and therefore mtDNA cannot be used to trace the patrilineal ancestry of a given person or population.
identify the remaining processes and componets of the carbon cycle
Answer:
Carbon is one of the most vital element for the existence of life. The carbon cycle is the one in which the carbon is transferred from the atmosphere to the living organisms i.e both plants, animals and to the earth and again back into the atmosphere, thereby maintaining a cyclicity.
Explanation:
Fireflies emit light. The production of light by an organism is called bioluminescence. To generate visible light, cells in a firefly's tail produce thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of the following best describes how the luciferase enzyme speeds up the chemical reaction? F Luciferase increases the amount of time the light is visible. G Luciferase decreases the amount of energy required for the reaction to start. H Luciferase increases the number of sites on luciferin that must bind to oxygen. J Luciferase decreases the temperature of the environment inside the body of the firefly.

Explanation:
b
The description that best describes how the luciferase enzyme speeds up the chemical reaction is - Luciferase decreases the amount of energy required for the reaction to start.
Fireflies generate a chemical reaction that allows their body to emit light, inside their body. This light generation is called bioluminescence. This process involves various steps:
Oxygen binds with calcium, luciferin chemical with ATP to make oxyluciferin.In the body of fireflies, there is the production of an enzyme called luciferase.This chemical reaction takes place in presence of luciferase that speeds up this reaction by decreasing the activation energy of the reaction.At the end of the reaction body of fireflies light up.Thus, the correct answer is - Luciferase decreases the amount of energy required for the reaction to start.

Planets that orbit the sun is a gas giant, terrestrial, or dwarf planet.
Answer:
Terrestrial i think:)
Explanation:
A solar system is made up of a star and the planets that orbit it. Our solar system’s four inner planets—Mercury, Venus, Earth, and Mars—are closest to the sun. They are called terrestrial planets, and are largely composed of rock and metal. The four outer planets—Jupiter, Saturn, Uranus, and Neptune—are gas giants.
it's known that only 9 planets orbit the Sun. There have been many solar system objects that have been discovered recently, but none of them have been classified as planets.
Gas dwarf A low-mass planet composed primarily of hydrogen and helium.
Gas giant A massive planet composed primarily of hydrogen and helium.

Which of the following factors is most likely to decrease the stability of an ecosystem?
A
The removal of a species
B
An increase in plant biodiversity
C
The removal of an individual animal
D
An increase in animal biodiversity
Answer:
A
Explanation:
The removal of a species can reduce the food source of another species, which can cause that species to slowly die out, where other animals that consume the dying species start dying out... ect.
So it decreases the biodiversity which can mess with populations.
If the species is a herbivore, it could cause the plants that are eaten by that herbivore to get out of control in population, which can fight for sunlight and resources with other species causing ecosystem collapse.
In an ecosystem, the removal of a species can decrease the stability. Thus, option A is correct.
What are the biotic factors of an ecosystem ?Biotic factors are the basic unit of ecosystem where the living beings interact with each other and their environment.
There are two components of an ecosystem such as biotic and abiotic components, include distribution of energy in our environment.
Biotic components can be classified into autotrophs, heterotrophs and decomposers based on mode of nutrition.
Autotrophs are producer such as plants as they produce food through the process of photosynthesis.
Heterotrophs are the consumer depend on producer for their nutrient, which is further classified into three categories.
Primary consumers are herbivores rely on producers for food while secondary consumers depend on primary consumers. They can be carnivores or omnivores.
Tertiary consumers depend on secondary consumers for food. some quaternary consumers are also seen in some food chains.
Decomposers include saprophytes such as fungi and bacteria which lie on decaying organic matter and essential for the ecosystem
Hence, option A is correct.

If the fatty acid palmitate (16:0) radiolabeled with 14C in C-16 were metabolized by mammalian cells under anaerobic conditions, what compounds would be tagged with 14C and in what position
The options are missing from the question,
Below are the options.
A) Tag would be CO2
B) Acetate in C-2
C) 1 uvate in C-3
D) pyruvate in C-3
E) oxaloacetate on C-1
F) palmitate in C-16
The correct answer to the question is option B
ACETATE IN C-2
If palmitate (16:0) which is a fatty acid radiolabeled with 14C in C-16, when metabolized under anaerobic conditions by mammalian cells,the compound that will be tagged with 14C will be ACETATE and the position it will be will be C-2
In an anaerobic condition, anaerobic CoA which is formed after the oxidation of fatty acid will now move into the Kreb cycle as a result of oxygen deficiency, taking the form of acetate,it will enter cytosol and will further be used for other purposes.
