Answer:
Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome.
Ex: hemophilia
hope this helps
have a good day :)
Explanation:
Answer:
The TATA box helps bind the <em>RNA polymerase</em> in the correct place.
Explanation:
The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.
The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.
Answer:
The correct answer is D. proliferation and differentiation.
Explanation:
Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.
Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.
So the correct answer is D. proliferation and differentiation.
The correct answer in this question is letter B. Taste buds that are located at the tongue recognize some dissolved chemicals from the food for taste perception. Examples are hydrogen ions giving off sour taste, carbohydrates for sweet taste, magnesium ions give off bitter taste, sodium ions for salty taste and monosodium glutamate for umami taste.
The answer to this is protein.
Hydrochloric acid in digestive system is found in stomach, which is the only main digestive organ with an acidic pH 2.
In the stomach, only one kind of the primary food substance is chemically digested, which is protein. It is digested with the help of enzyme Pepsin, which breaks protein chains into polypeptides.
After that, the other organs of the digestive system has more of a neutral to slightly alkali condition, which is not related to hcl. Therefore, the answer is protein.
