The lock and key mechanism of enzyme and substrate means that if they don't fit, it is the wrong substrate or the enzyme is denatured.
WHAT IS AN ENZYME?
An enzyme is a protein substance that regulates biochemical activities in living cells by acting as a catalyst. Enzymes act on substrates but they do not get changed during the process. This means that enzymes can be used over and over again. Enzymes are substrate-specific i.e. they act on specific substrates. The lock and key model explains the mechanism of action of enzymes. Enzymes attach to substrate at their active sites and act on them to form products.The lock and key model explains that if enzyme and substrate don't fit, it is either the wrong substrate or the enzyme is denatured.

Behind your house, there's a gorgeous pond filled with frogs. You notice that the frogs behind Mr. Archer's house often have three legs. You start wondering if the fertilizer that Mr. Archer uses for his lawn is causing the deformities in the frogs. You collect 10 frogs and put the special fertilizer in their container (Group A). You put another 10 frogs and place them in a different container with just water (Group B). A week later, 7 out of 10 of the frogs in group A grew only three legs. The frogs in group B grew four legs.

The nuclear lamina is an array of filaments on the inner side of the nuclear membrane. If a method were found that could cause the lamina to fall into disarray, what would you most likely expect to be the immediate consequence
Answer:
The nuclear lamina is an array of filaments on the inner side of the nuclear ... If a method were found that could cause the lamina to fall into disarray, ...
Explanation:
1. The nuclear lamina is a network inside the nucleus which maintain the shape of nucleus.
2. It is composed of intermediate filaments and many proteins.
3. It providing mechanical support to the nucleus and play many other rolls in the cell.
4. In a cell if the nuclear lamina fall into disarray, the nucleus is misshapen and all these processes run awry. Such cells in which nuclear lamina is broken, they tend to become senescent in response to internal dysfunction, and cause damage to surrounding tissue.
What is the process of nitrification?
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Fungi convert nitrogen in dead plants into ammonium, which converts proteins into ammonia.
Nitrogen is converted into a useable form through lightning fixation.
Plant enzymes reduce nitrogen compounds into amino acids.
Answer:
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.

Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide?(1 point)
Venus has a surface of high mountains which absorb heat.
Mars has a surface of red rocks and sand which reflect heat.
Venus has a thick atmosphere which blocks heat from the surface.
Mars has a thin atmosphere that cannot hold much heat.
Mars and Venus are the planets of the solar system and vary in their temperatures. Mars has a thin atmosphere that cannot much amount of heat. Thus, option D is correct.
What is the atmosphere of Mars?Mars has been the fourth planet of the solar system that is also called the red planet due to its red appearance. It has more amount of carbon dioxide than oxygen gas. It comprises various gases and has a thin atmosphere.
The thin atmosphere of Mars unlike Venus cannot hold the heat and transmits it back to space. Venus has a thick atmosphere that traps heat and results in an increased surface temperature. The atmospheric particle of Mars cannot retain heat and hence vary in temperature.
Therefore, option D. Mars has a lower temperature than Venus due to its thin atmosphere.

A statement in the introduction read, “All other factors remained the same between the two groups.” Make a list of factors that must remain constant in the experiment.
The factors that must remain the same in an experiment are known as control variables.
In order to conduct a proper experiment, there must be 3 kinds of variables. These are:
Dependent variableIndependent variableControl variableA dependent variable is a variable that the experiment seeks to observe, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable.
The variables referred to in the question are control variables. Control variables are the factors that must remain constant in an experiment. This is to ensure that when we measure a change in the dependent variable, we know to attribute it to the correct cause of the change. The presence of control variables helps to ensure a valid experiment and limits the influence of other factors on the outcome.

How does hydrogen peroxide get into cells?
Answer:
when a cell creates hydrogen peroxide, it stores it inside the cell's specialized organelles, called peroxisomes, which contain hydrogen peroxide-busting catalase.
Explanation:
Hydrogen peroxide gets into the cell with the help of an enzyme called peroxide dismutase, which significantly catalyzes the process of dismutation of superoxide radicals in order to synthesize H2O2.
What is Hydrogen peroxide?Hydrogen peroxide may be defined as a liquid chemical that typically contains hydrogen and oxygen and is generally utilized for bleaching and as an antiseptic.
Hydrogen peroxide is consistently produced in the cell and then stored in the organelle known as the peroxisome. The cells then eliminate the excess amount of hydrogen peroxide (H2O2) with the action of an enzyme called catalase. And gest dissociates into the water (H2O) and molecular oxygen (O2).
Therefore, the process of production and digestion of hydrogen peroxide in the cell is well described above.

An Allele is best described as:
A. A version of a gene
B. A recessive gene
C. A dominant phenotype
D. A test cross
An allele is best described as a version of a gene. Option A is correct answer.
Genes are segments of DNA that contain instructions for the development and functioning of living organisms. Each gene can exist in different forms, called alleles.
For example, let's consider a gene that determines eye color. This gene can have different alleles, such as brown allele, blue allele, and green allele. Each allele represents a different version or variant of the gene.
The different alleles of a gene can lead to variations in traits or characteristics. In the case of eye color, individuals with two copies of the brown allele will have brown eyes, individuals with two copies of the blue allele will have blue eyes, and individuals with one copy of the brown allele and one copy of the blue allele will have a mix of brown and blue eyes.
So, the correct answer is A. A version of a gene. An allele represents different versions of a gene that can result in variations in traits or characteristics.
Option A is correct answer
