A
B
a
b
Answer:
small a and small b because the big ones are dominant the others recessive
The recessive alleles represented in the genotype AaBb is a and b.
What is recessive and dominant allele?Alleles can be dominant or recessive. We call someone dominant who has achieved a certain characteristic. The recessive can only express itself in pairs.
Thus, as it is a pair and knowing that the recessive alleles are shown with lowercase letters we have to be ab.

Biofuels are fuels derived directly from living matter. Read this article about a scientist who discovered how one bacterium can transform plants into usable energy. Then answer the following questions. Today, many people read only the headlines of news stories instead of taking time to read the entire article. This habit can lead to misconceptions about the actual story. What misconceptions could someone have by reading just the headline of this article? How are these misconceptions clarified if the entire article is read?
Answer:
The headline suggests that using bacteria to turn plants into biofuel is a simple process. But reading the article reveals that there were many different types of scientists involved in the process. Also, the headline gives the misconception that this process is so simple that it’s ready to be used. But the last paragraph of the article states that this process has only been done on a small scale, and transforming the process for the entire industry would likely be quite difficult.

What impact does deforestation have on the carbon cycle?
Answer:
Deforestation can affect the water cycle and the carbon cycle. It will decrease the amount of transpiration. It will also increase the amount of carbon dioxide in the atmosphere by releasing the carbon dioxide as trees are burned and by decreasing photosynthesis.
describe the six functions of membrane proteins
Answer:
All enzymes are a type of protein. As a result, a membrane protein that is embedded into the membrane can sometimes be an enzyme, which may have its active site facing substances outside of the lipid bilayer.
These types of enzymatic membrane proteins can work in teams to carry out the steps in a particular metabolic pathway, for instance breaking down lactose into carbohydrate and then monosaccharides.
Membrane proteins can allow hydrophilic molecules to pass through the cell membrane. Transport membrane proteins come in many forms, and some require energy to change shape and actively move molecules and other substances across the cell membrane. They do this by releasing ATP to use as an energy source.
Anchorage: become points of attachment for the cytoskeleton and the extracellular matrix
Some membrane proteins can feature a binding site. These binding sites are characterized by specific shapes that match the shape of a chemical messenger. For example, these chemical messengers can be hormones.
When a hormone meets with the cell wall, it will connect with a receptor membrane protein that is embedded inside the cell wall. The hormone can change the receptor protein and cause a specific reaction, depending on the type of hormone or other substance, will take place within the cell.
Another important function of membrane proteins is in identification and recognition between cells. This particular function is useful in the immune system, as it helps the body to recognize foreign cells that may be causing infection, for instance. Glycoproteins are one type of membrane protein that can carry out cell recognition.
Adjacent cells may have membrane proteins that connect in a range of different junctions. Gap junctions and tight junctions.
This function helps cells to communicate with one another, and to transfer materials between one another.
Membrane proteins are important in the cytoskeleton, the system of filaments and fibers in the cytoplasm of a cell, and the extracellular matrix (ECM), which is the network of macromolecules found outside of cells, such as collagen, enzymes, and glycoproteins, to membrane proteins.
Attaching filaments or fibers in the cytoplasm found throughout the cell can help the cell to maintain its particular shape. It also keeps the location of membrane proteins stable.
Attaching membrane proteins to the extracellular matrix can help the ECM to mediate changes that occur in extracellular and intracellular environments.
Several diseases are linked to mutations within membrane proteins. One example is a mutation called V509A, found in the thyrotropin receptor, thyrotropin being a hormone secreted by the pituitary gland that regulates the production of thyroid hormones.
This mutation increases the activity of the thyrotropin receptor and leads to congenital hyperthyroidism, a condition that can cause changes in mood, sleep problems, and stomach problems.
Other diseases that are linked to mutations in membrane proteins include hereditary deafness, Charcot-Marie-Tooth disease, which damages the peripheral nerves outside the central nervous system, and Dejerine-Sottas syndrome, that affects a person’s ability to move.

Suggest why a cell within the trunk of a tree cannot carry out photosynthesis.
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.
Explanation:
The trunk of a tree consists of dead tissues and serves only to support the weight of the tree crown. This portion of the tree does not contain chloroplast, hence photosynthesis is not carried.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The part of the trunk region of the tree does not have chloroplast, chlorophyll pigments, and other required machinery which is significantly utilized by the leaves of the tree in order to perform photosynthesis. Due to this, the trunk part of the trees is not capable to carry out the same process.
Therefore, the most prominent reason why a cell within the trunk of a tree cannot carry out photosynthesis is well described above.

Depending on the organism, the optimal pH for enolase to catalyze its reaction is between 6.5 and 8.0 . Describe how a pH below or above this range is likely to affect enolase and its catalytic ability.
Answer:
Enolase are enzymes, when a enzyme goes into a different ph level that is not used to, it will be denatures and will lose its catalytic ability.
Enolase are enzymes, when a enzyme goes into a different ph level that is not used to, it will be denatures and will lose its catalytic ability.
What are enzymes?Proteins called enzymes aid in accelerating our bodies' chemical reactions, or metabolism. Some compounds are created, while others are broken down. Enzymes are a part of all living things.
Enzymes are created by our bodies spontaneously. However, food and manufactured goods both contain enzymes.
The body contains tens of thousands of different enzymes. Every type of enzyme has a single function. For instance, the enzyme sucrase degrades the sugar sucrose. Lactose, a type of sugar included in milk products, is broken down by lactase.
Therefore, Enolase are enzymes, when a enzyme goes into a different ph level that is not used to, it will be denatures and will lose its catalytic ability.

Explanation:
Which is a correct statement?
Select one:
a. As porosity increases, permeability stays the same
b. As porosity increases, so does permeability
c. As porosity increases, permeability decreases
d. Porosity and permeability are unrelated
help pls!!!
As porosity increases, permeability decreases It increases as particle length increases. via definition, permeability is a measure with which fluids will go with the flow though a porous rock, soil or sediment. a material that has high porosity does not have to have high permeability.
Smaller particles have a low permeability. this is due to the fact there's less space among debris, which reasons a lower porosity, which makes water travel slower through the ground. Smaller debris have a higher capillarity.
Porosity is the amount of pore area that is between particles in soil or rocks. Permeability takes this pore space and connects the voids collectively so that water can pass thru. Porosity is extra associated with garage of water, whilst permeability is extra related to groundwater motion and flow.
To calculate the permeability of a porous material, use Darcy's law equation: Multiply together the fluid discharge fee, dynamic viscosity, and distance traveled. Divide the end result from step one with the aid of the move-sectional place of the fabric elevated with the aid of the strain difference on either aspect of the material.

The answer is C) Commensalism
Explanation:
The reason is due to the fact that there is evidence in the paragraph describing the relation of two species. If you look in the last sentence of the paragraph, it says, "The relationship between 2 species that can be represented as +/0"
The symbol +/0 is actually saying/meaning one side is benefited while the other side is neutral or not benefited!
The picture shown bellow will help!
Commensalism = +/0 (One side is benefited while other isn't benefited or hurt)
Mutulaism = +/+ (Both sides benefit each other)
Parasitism = +/- (One side benefits while other is harmed)

Peptide bonds in proteins can be broken down by the enzyme peptidase. Adrian orders a hamburger and French fries for lunch. He adds cheese and mayonnaise to his hamburger, and then sits down to eat lunch with his friends. Which structure would MOST likely result from the action of peptidase in Adrian’s small intestine?
Answer:
Hello. I think the answer is small peptides and amino acids.
Explanation:
Proteins are polymers that their monomer is amino acid.
First digestion of proteins accurs in stomach.
Stomach enzymes digest proteins but not to amio acid. They digest it to small peptides.
Then the other proteins and small peptides enter the small intestine.
In small intestine peptidaze digests proteins and transform them to small peptide.
The small peptides that came from stomach are digested to amino acids and most of them is absorbed by the epithelial cells of intestine wall.
I hope you understand.
Amino acid is the structure would MOST likely result from the action of peptidase in Adrian’s small intestine.
Proteins are made up of monomers of amino acids. Adrian diet is rich in proteins that is present in hamburger and French fries along with the cheese and mayonnaise.The food passes through various organs in the body of the digestive system where digestion of food occurs.The proteins are first digested in stomach then in the intestine. In the intestine the proteins are broken down into peptides and further into amino acids by the enzyme peptidase.Hence, amino acid is the correct answer.
