Answer:
Light energy is converted to chemical energy.
Please find the explanation below
Explanation:
Photosynthesis is a unique process that occurs in the cells of green plants and other autotrophic organisms. It is the process whereby they synthesize their food in form of carbohydrates (sugars). The photosynthetic process takes place in two stages namely: light dependent reaction and light-independent reactions.
The light dependent reaction or simply light reaction is the stage where light energy from the sun is harnessed by a pigment called CHLOROPHYLL and used to produce ATP needed to build glucose molecules in the next stage. Hence, via this process, the LIGHT ENERGY from the sun is converted to CHEMICAL ENERGY in ATP.
What would happen to an animal cell with an internal salt concentration of 0.8% if it were placed in a salt solution with a concentration of 0.2%? Why?
Answer:
This simply explain the concept of osmosis. A solution of 0.8% is lower in conc. (hypotonic)compare to that of 0..2%(hypertonic)Therefore, the inner cells layer would lose water to higher hypertonic concentrated medium.
water flows from .8% to salt solution of 0.2%
This follows the concept of osmosis which is the movement of water molecule from the region of higher water potential(.08) to region of lower water potential(0.2) but high solute potential, through a semiportable ,membrane, the plasma membrane.

a mutation in which type of cell would only affect the organism and not future generation
Answer:
Somatic cells
Explanation:
A somatic cell mutation in an organism is passed on to the daughter cells in an organism. But this type of mutation doesn't affect the future generations because only genes carried by sperm or ova can become part of offspring's gene material.

In the movie Darwin struggled with publishing his ideas on Evolution by Natural selection. He was afraid of the cultural implications of his discoveries. Do you think his idea of Evolution by Natural Selection was a "dangerous idea"? Back up your claim with evidence from the video and 1 other source. Explain your reasoning.
Answer:
Yes.
Explanation:
Yes, I think Darwin idea of Evolution by Natural Selection was a "dangerous idea" because the people at that time was unable to understand his idea. The people at that time had their own believes which they were followed and rejected everything which were against their believes so this idea of evolution was against the idea of people at that time due to which Darwin was afraid of the cultural implications of his discoveries.
According to the cell theory, where do cells come from?
Answer:
preexisting cells :)
Explanation:
Answer:
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

Explanation:
1. "For oxygen to enter the blood, how must the concentration of O2 in the alveoli compare to O2 in the blood?" 2. "For carbon dioxide to leave the blood and enter the alveoli, how must the concentration of CO2 in the blood compare to CO2 in the alveoli?" 3. "When diffusion has reached equil- ibrium, we say that the net movement of the molecules is zero. Does movement stop? Explain."
Answer:
1. Concentration of O2 in the alveoli must be more than that of the blood
2. Concentration of CO2 in the blood must be more than that of the alveoli
3. Movement does not stop (find the explanation below).
Explanation:
Gaseous exchange i.e. taking in of O2 and taking out of CO2, takes place in the alveoli/air sac of the lungs. However, the movement in and out of O2 and CO2 from the alveoli into the bloodstream and vice versa follows the principles of SIMPLE DIFFUSION. Diffusion is the process whereby substances move from a region of high concentration to a region of low concentration until they are evenly distributed. Based on this, the following will occur:
1. The concentration of O2 in the alveoli must be more than that in the blood in order for oxygen to enter the blood via diffusion.
2. The concentration of CO2 in the blood must be more than that in the alveoli in order for carbon dioxide to leave the blood and enter the alveoli via diffusion.
3. When the rate of diffusion is at equilibrium i.e. no net movement is occuring die to equal concentration of the substance on both sides, the substances begin to move in the opposite direction at an equal rate. Note that, at equilibrium, MOVEMENT DOES NOT STOP, however, there is an equal rate of movement.

Hydrogen peroxide naturally breaks down into oxygen and water over time. When exposed to the enzyme catalase, hydrogen peroxide is rapidly converted into oxygen and water.
What feature of catalase most likely is responsible for the change in the rate of conversion of hydrogen peroxide into water and oxygen?
A, Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy.
B, Catalase bonds permanently with the reactants causing hydrogen peroxide to rapidly break down by increasing the activation energy.
C ,Catalase has a flexible structure that allows it to bind and convert any small hydrogen containing compound into water and oxygen.
D, Catalase remains intact, so small amounts of it convert large amounts of hydrogen peroxide into water and oxygen immediately.
Answer:
Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Completely disinfect any surface that the raw liver touches during this activit.
Explanation:
hope this helps you a little have a great day sir/mam
Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy. Thus option A is correct.
What is the function of catalase ?Catalase is a common enzyme present in all living organisms.
These are tetramer molecule consisting of four polypeptide chains, each of these chains are over 500 amino acids.
In mammal it is found in liver and contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide.
In mammalian cell, Catalase involve in decomposition of most toxic substance called hydrogen peroxide into less toxic products like water and oxygen.
It protect the cell from oxidative damage by reactive oxygen species.
The optimum pH and optimum temperature for the activity of this enzyme ranges from four and eleven depending on the species.
Thus option A is correct.

If the structure of a specific organ protein is temporarily changed due to the chemistry of the protein's local environment, what else may be temporarily influenced?
Answer:
Function of protein also temporarily changed.
Explanation:
If the structure of a specific organ protein is changed temporarily due to the local environment of protein, the function of the protein also changed temporarily because the structure of protein changed which does not allow suitable environment for the proper functioning of the protein so we can conclude that the function of the protein also temporarily changed.

predict what would happen
to the biotic and abiotic factors in Fontanelle Forest and the surrounding
area ecosystem with the increase of deer.
Answer:
With increase of deer, there will be a decrease of producers.
Explanation:
Increasing of deer populations means decreasing of producers. As more and more deers are eating plants, the producer population will decrease. Thus, the producer population are in demand and deers will eventually need to fight for food with other deers–– this is known as competition, which is a biotic factor. An abiotic factor can be lack of oxygen once the producer population has been decreased due to the increase deer population.

Some cells are specialized for
facilitated diffusion, a form of passive
transport. What sorts of structures
would these cells have more of?
Answer:
The cells specialized in passive diffusion have a greater amount of membrane structures called transport proteins.
Explanation:
Facilitated diffusion is a transmembrane transport mechanism, which consists of the passage of substances through the cell membrane by means of a transporter.This process does not require energy, as it is a passive transport, and depends on an ionic gradient or concentration.
The carriers of facilitated diffusion can be integral membrane proteins, so a cell specialized in this type of transport must have abundant transport proteins.

Question 1
Explain why your model demonstrates how crossing over is important to genetic variation in a species.
Question 2
Look at the offspring you created in your model. Have any of the offspring inherited a more beneficial genetic combination than the others? How could this affect their survival? Explain your reasoning.
Question 3
Why is it impossible to predict the phenotype of the offspring by observing only the phenotype of the two parents?
Answer:
the last one is:
In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.
Explanation:
Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.
What do you mean by crossing over process?Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.
