Answer:
The woman's genotype - Bb
The man's genotype - bb
Chances of having a child with blue eyes - 50%
Chances of having a child with brown eyes - 50%
Explanation:
Many of our traits are determined by our genetics. We inherit genetic information from both of our parents. From each of them, we get one copy of a gene that determines a certain trait. These gene copies are called alleles.
The dominant allele is the one that masks the effect of the other type of allele, called the recessive allele. This means that a person needs to have only one dominant allele in order for its effect to be expressed. In order for the effect of the recessive allele to be expressed, the person needs to have two recessive alleles.
If a man has blue eyes, which is a recessive trait, he needs to have two recessive alleles (bb). This is why the genotype of the man is bb.
If his child has blue eyes, this means that its genotype is bb as well. The mother's eyes are brown, which means that she needs to have at least one recessive allele. Based on this, we can conclude that her genotype is Bb.
Since the mother has one dominant allele, this means that her children could have brown eyes as well. This is what the Punnett square would look like:
B b
b Bb bb
b Bb bb
Two out of four children would have brown eyes, and the other two would have blue eyes. This means that their chances of them having a child with blue eyes are 50%. The chances of them having a child with brown eyes are the same.

what's the function of adrenaline in our body
well
my account got deleted rosa
Answers
Answer:
What is the function of adrenaline?
Adrenaline triggers the body's fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs. The body's ability to feel pain also decreases as a result of adrenaline, which is why you can continue running from or fighting danger even when injured. Adrenaline causes a noticeable increase in strength and performance, as well as heightened awareness, in stressful times. After the stress has subsided, adrenaline’s effect can last for up to an hour.
Explanation:
I think I helped
Answer:
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).
Protein molecules are the building blocks of the body. They are made up of long chains of amino acids. Draw the general structure of an amino acid.
Answers
Answer:
Please find the diagram of the general structure of amino acids attached.
Explanation:
Proteins are one of the four major biomolecules in living systems. As rightly stated in this question, they are building blocks of the body. However, proteins are biological polymers made up of monomeric units called AMINO ACIDS. A long chain of these amino acids make up a protein molecule.
An amino acid generally consists of a central carbon atom called ALPHA CARBON, attached to an amine group (-NH2), a carboxylic acid group (-COOH), and a side chain (R side chain). All 20 amino acids that exists in nature have this general structure but differs only in the type of SIDE CHAIN (R group) they possess i.e. all amino acids have a different R side chain.
Please find the diagrammatic representation of the general structure of amino acids as an attachment.

What will happen to a protein when the DNA codes for a different amino acid?
Answers
If a mutation occurs in the DNA let's say a point mutation only one of the base pairs will be different. The codon will be different so a different amino acid will be synthesized. Amino acids have different radicals with different functional group. Those radicals that differ from amino acid to amino acid determine the shape and function of the protein. Therefore a mutated gene will cause the synthesis of a protein with an altered shape and function. A good example is sickle cell disease. Where glutamic acid is replaced with valine and the beta chain of hemoglobin has a deformed shape and has an altered function(carries less oxygen).

Pathogenic bacteria Pathogenic bacteria are unique because they have a membrane covering the filament. do not have flagella. have a unique basal body structure. can be identified and classified by differences in their flagellar proteins.
Answers
Answer:
D. can be identified and classified by differences in their flagellar proteins.
Explanation:
Pathogenic bacteria are unique because they can be identified and classified by differences in their flagellar proteins. Flagellin protein is a distinct component of the flagellum, which is a whip-like structure attached to the back side of the pathogenic bacteria that helps the bacteria to move in forward direction. Some bacteria are Monotrichous bacteria means have a single flagellum while some bacteria are Lophotrichous bacteria means have multiple flagella at the back side of its body.
Answer:
can be identified and classified by differences in their flagellar proteins.
Explanation:
Pathogenic bacterias are forms of bacteria that can be identified in various ways.
One of the ways to identify them is through examining of their features which can be classified by differences in their flagellar proteins.
Another way to identify them is knowing that they are the type of bacteria that causes infections in the host.
For example, Salmonella and E. coli

Carbon cycle contains an important stage called Carbon fixation. This
stage - Carbon fixation changes carbon dioxide into organic compounds
such as glucose. Which of the following organisms cannot fix carbon? *
algae
maple trees
mushrooms
grass
Answers
Answer:
Mushrooms
Explanation:
Carbon fixation is the process by which inorganic carbon is converted to organic compounds by living organisms. This type of carbon can be found in carbon dioxide.
Carbon dioxide is necessary for the survival of many organisms. Organisms that possess the pigment called chlorophyll perform photosynthesis. In this process, with the help of sunlight, they transform carbon dioxide, water, and minerals from the soil into oxygen, which is released into the atmosphere, and glucose, which they feed on. Organisms that possess chlorophyll are most plants and some protists and bacteria.
Algae, maple trees, and grass are all examples of organisms that perform photosynthesis, which means that they fix carbon.
Mushrooms can't do this as they are fungi, and fungi are not capable of photosynthesis.

What medium does sound waves travel the fastest
In (solid, liquid, or gas) why？
Answers
Answer:
Sound travels fastest in solids and slowest in air. Water is in between. This is because the particles in solids are closer together than the particles in liquids or gases, and the particles in liquids are closer together than the particles in gases. The tighter particles are packed in a space, they collide more frequently. This allows sound, which is simply the combined collisions of particles, to travel fastest in solids. So, to reiterate, sound travels fastest in solids, then water, and slowest in air.
