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.

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.

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?
Answers
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.

Radish color is controlled by a gene that exhibits incomplete dominance; purebred red radishes (RR) crossed with purebred white radishes (WW) make purple radishes (RW). What are the chances of producing purple offspring when you cross two purple parents?
Answers
Answer:
1/2
Explanation:
This question involves a single Gene coding for fruit color in radish plants. The gene exhibits incomplete dominance where the allele for red radish (R) and the allele for white radish (W) forms a hybrid with a purple radish (RW).
If a purebred red radish (RR) is crossed with purebred white radishes (WW), purple radishes (RW) will be formed. However, when the purple radishes are self-crossed i.e. RW × RW, the following gametes will be produced- R and W.
Using these gametes in a punnet square (see attached image), the following offsprings will be produced in the following proportions:
RR - red = 1/4
RW - purple = 2/4 or 1/2
WW - white = 1/4
Hence, the chances of producing purple offspring when you cross two purple parents is 1/2.

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."
Answers
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.

Answers
Answer:
Fern
Explanation:
The plant discovered by the botanist is most likely a fern.
Ferns are referred to as seedless vascular plants. They do not produce seeds and they possess vascular tissues in the names of xylem and phloem. The xylem conducts water/mineral salts from the roots to the body of the plant while the phloem distributes manufactured foods from their sources to other parts of the plant.
Ferns also have independent gametophyte and sporophyte stages. The sporophyte produces haploid spores through meiosis which then germinates to the gametophyte. The gametophyte produces male and female gametes - antheridium and archegonium. The antheridium is motile and swims to meet the immotile archegonium during fertilization to produce the zygote which then divides mitotically to give the sporophyte.

Why does diuron cause coral to bleach
Answers
Simple answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.
More in depth explanation:
Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

Answers
Answer:
They are working in the best interests of corporations
Explanation:
Corporations and industries are responsible for a large percentage of environmental pollution being witnessed in several regions of the world. The pollutions have negative consequences for the environment and the organisms living in it, including humans. Hence, formulating laws to regulate the amount of pollution that can be added to the environment is in the best interests of the public. Any person that fights against these laws is likely working in the interests of industries and corporations and not the public in its entirety.
