Test (Photosynthesis & Cellular Respiration) 1) Describe how the Electron Transport Chain works. Be sure to focus on the role diffusion plays in the ETC This should be 4 sentences.
Answer:
The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

Which animals have adapted to near-freezing water?
A. Barnacles
B. Animals in coral reefs
C. Fishes in polar areas
D. Whales
Answer:
C/D
Explanation:
Unfortunately, I can't give a straight answer since it doesn't specify if the fish belongs in the water, all I know it that it's a plain fish in polar water. So D is probably the answer. Since some whales live in polar areas.

Insta: 25k_kemWhy must cells divide to stay small or change shape to reduce volume?
O To diffuse substances from an area of higher to lower concentration
To ensure the cell is able to obtain nutrients or remove wastes.
To reduce surface area of the cell for quick movement.
O To move water molecules from areas of high to low pressure
Answer:
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Explanation:
Answer:
To ensure the cell is able to obtain nutrients or remove wastes.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume That is why cells are so small.
Which factor may increase a rabbit population?(1 point)
decrease in space
decrease in temperature
decrease in food
decrease in predators
Answer:
D. Decrease in predators
Explanation:
The lack of predators would cause less death to the rabbit population, with less hunters to kill the rabbits the population will increase and further increase if they reproduce.
The factor that will increase a rabbit population is ( D ) Decrease in predators
Rabbits as primary consumersRabbits are herbivores that feed on nuts and grasses they are primary consumers and are prey to so many secondary and tertiary consumers ( i.e predators ).
A decrease in space will result to lose of habitat and this will decrease the population of rabbits also extreme weather conditions might lead to death of rabbits just like decrease in food will cause starvation and eventual death for rabbits as well.
While a decrease in predators will result in the survival of more rabbits ( i.e increase in population )
Hence we can conclude that The factor that will increase a rabbit population is Decrease in predators.

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait.
A Punnett square is shown. The columns are labeled Upper F and f. The rows are labeled Upper F and f. Clockwise from upper left the boxes contain: Upper F Upper F, Upper F f, Upper F f, f f.
Based on the Punnett square, what is the probability that the offspring will have freckles?
25 percent
50 percent
75 percent
100 percent
Answer:
75%
Explanation:
Three of the boxes contain an Upper case F, therefore 75% of the boxes have an Upper case F. It's like quarters, if you have 4 quarters you have 100 cents, if you have 3 you have 75 cents, if you have 2 you have 50 cents, and if you have 1 you have 25 cents.

Which is a density-dependent factor?
Answer:
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

How would you describe dominant in a different way then this? In a easy way?
Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. The allele is dominant because one copy of the allele produces enough enzyme to supply a cell with plenty of a given product.

Answer:
c
Explanation:
because thats what I think the answer can be
B. pluripotent stem cell. Pluripotent stem cells are a type of stem cell that have the ability to differentiate into many different types of cells, including blood cells.
What are pluripotent cells?Pluripotent stem cells are a type of stem cell that have the ability to differentiate into many different types of cells, including blood cells. They are "pluripotent" because they can give rise to many different cell types, as opposed to more specialized stem cells, such as multipotent stem cells, which can only differentiate into a limited number of cell types.
Pluripotent stem cells are important because they have the potential to be used for regenerative medicine and to treat a wide range of diseases, such as blood disorders, cardiovascular disease, and neurodegenerative diseases. They can also be used to study early human development and to understand the underlying mechanisms of disease.

Essential amino acids cannot be produced by the body, so they must come from our diet. We can get them from eating foods that contain which
Answer:
The question is incomplete because the options are not given but the options are gotten from another websites which are;
a. protein
b. complex carbohydrate
c. fats
d. disaccharides
The correct option is a.
Protein.
Explanation:
Proteins are macro nutrients or biomolecule whose building blocks is t amino acids. Amino acids consists of organic compounds like hydrogen, nitrogen, carbon, oxygen and may also contain sulfur which all serve as protein building blocks . Our body requires proteins which contain amino acids and these are important for growth, body building and and proper functioning. These include both essential and non essential amino acids
The essential amino acids includes histidine, isoleucine, lysine, phenylalanine, tryptophan and valine cannot be produce by the body but can be gotten from diets that are from protein source. The major sources of essential amino acids are gotten from animal proteins and they include meat, eggs, and poultry.
A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Answer:
Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.

B. translation
The nucleus is the site of transcription in protein synthesis.
What do you mean by Transcription?Transcription may be defined as a process through which a cell makes a copy of RNA (mRNA) from a strand of the DNA.
These messenger RNA carries the genetic information which is essential to make a protein in a cell. The process of transcription occurs in the nucleus of the cell.
While translation is the process by which the sequences of mRNA may transform into proteins. This process occurs in the cytoplasm of the cell.
Therefore, the nucleus is the site of transcription in protein synthesis.
