Where’s the key to answer the question?
Alleles are alternative form of gene and are present at same place on chromosome
suppose the two alleles S and T are controlling leaf colour so the genotype that will b possible is SS.ST.TT and for species B the 6 phenotypes will occur so i conclude that
<span>Species B will have a wider range of phenotypes
</span>so D is correct
hope it helps
The correct answer is c.stops after infancy and childhood.
Myelin is the substance of the central nervous system (CNS) that insulates nerve cell axons to increase the speed at which nerve impulse travels. Myelination is a process of myelin formation. This process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.
