Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
Answer:
A hair follicle anchors each hair into the skin.
Explanation:
The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.
Answer:
conscious neural control
Explanation:
Neural control of digestive tract is unconscious achieved via the autonomic nervous system.
Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:
• The myenteric plexus – controls digestive tract motility
• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.
<span>Dialysis patients are prone to a myriad of medical anomalies. The most common medical conditions that dialysis patients have in addition to kidney failure are hypertension and diabetes. Hypertension is the onset of high blood pressure, and diabetes is a disease that prevents the pancreas from regulating glucose levels in the body.</span>
Answer:
4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.
Explanation:
Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.
Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.
The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).
RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes
RRtt, Rrtt -> Red petals with short bushes
rrTt, rrTT -> pink petals and tall bushes
rrtt-> pink petals with short bushes.
These are the four phenotype variations possible in this dihybrid cross.
