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.

Why do people feel fireworks before hearing it?
Answer:
People feel fireworks before hearing it because light travels faster than sound.
Explanation:
We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

A population of foxes inhabits a small forest. The size of the population is currently below the forest's carrying capacity for the foxes. Which factor could cause an increase in the population's growth rate?
Answer: an increase of food
Explanation:
Answer and Explanation:
Answer: C. An increase in food availability increases the birth rate in the population.
Explanation:
The conveying limit of a biological system can be characterized as the greatest size of a populace of an animal types an environment can uphold based on accessibility of assets, for example, food, water, living space and different necessities.
An increase in food availability increases the birth rate in the population
is the right choice in light of the fact that to build the populace till the conveying limit there should be excess stock of food ought to be accessible to the populace which can uphold in expansion in birth rate so the populace can achieve a level at the conveying limit.
what are the possible blood types of a child whose parents are both heterozygous for b blood type
Answer:
I believe the answer is:
If both are BB, the child will be BB. If one is BB and one is BO, the child has a 50% chance of being BB and 50% chance of being BO - both of which result in type B. However, if both parents are BO, there is a 25% chance of BB, a 50% chance of BO, and a 25% chance of OO (which results in type O).

water breaks down into what 3 things during the light reactions
The process in which water is broken down during the light dependent reactions is called photolysis.
Reaction
H₂O-->1/2O₂+2e⁻+2p⁺
Atomic oxygen is released from the water molecule and reacts with another atomic oxygen to form molecular oxygen(O₂)
The hydrogen atom has only one proton and one electron so one hydrogen atom can be written as(e⁻+p⁺) in the water molecule 2 hydrogen atoms are present so there will be 2e⁻+2p⁺
Therefore the three things that result from photolysis are:

Which of these catastrophic events is caused by the warm air from the gulf of mexico and the cold air from the north super celll thunderstorms and has a funnel shaped clouds that produces high speed winds that canlift houses at a F5 scale ?
Answer:
Hurricane.
Explanation:
Hurricane and tornadoes are the catastrophic events that occur when the warm air from the gulf of Mexico and the cold air from the north combines together. These hurricanes and tornadoes causes a lot of damage and destruction if the speed and intensity are higher. These hurricanes produced in different region and causes destruction in another region due to its mobility.

5. Studying light from a star allows us to… a. determine a star's temperature b. determine what elements the star is made of c. determine how a star is moving (toward, away, fast, slow) d. all of these e. none of these
Answer:
The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"
Explanation:
All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.
One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.

Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.

What do you think would happen to the process of cell division if there is a deficiency in the Golgi apparatus's ability to package protein tubule materials?
Answer:
The process of cell division will slow down and the cell will die
Explanation:
Without the golgi apparatus or if its not working as well as it should be there would be no lysosomes or less. Without the lysosomes there will be a lot of junk/trash in the cell and it would have no way to break it down and get it out
During DNA replication, a complementary strand of DNA is made for each original DNA strand. Thus if a portion of the original strand is tcga actca, then the new strand will be
Answer:
agcttgagt
Explanation:
DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".
