They are female because they have two X chromosomes (as you can see at the bottom right of the picture) If they were male they would have one X chromosome and one Y chromosome.
They're called Enzyme. They're made up of proteins. They act as a biological catalysts that can speed up chemical reaction. They have an active site that certain substrates binds into it and form a product. Enzyme works under optimum pH and temperature and the active sites are not changed unless denatured.
Answer:
a and d
Explanation:
<em>Among the products of meiosis listed, aB and Ab would be the recombinant types because recombinant gametes are gametes that are unique from the haploid gametes that made up the diploid cell. </em>
A and B alleles are on a particular chromosome while a and b alleles are on another chromosome. During the process of gamete formation/meiosis, the possible gametes are;
<em>While the first two gametes are parental (because they made up the original diploid cell), the last two gametes are recombinant gametes.</em>
Hence, from the list of options, aB and Ab are the only recombinant types.
<em>The correct options are </em><em>a</em><em> and </em><em>d</em><em>.</em>

Answer:
The correct answer is - e. many different molecules form a signaling cascade.
Explanation:
Signal transduction is the number of events that take place inside the body of a human from the external atmosphere to transmitting a chemical or physical signal through a number of molecular events of signaling cascade.
The transmission of the particular chemical or physical signal is caused a sequence of phosphorylation events inside the cell it involves specific protein receptors and different types of molecules.
