What would be the outcome of crossing two strains of wingless flies that belong to the same complementation group?
STALIN [3.7K]

Answer:

Wingless offspring

Explanation:

Complementation is the terminology used for finding difference in the mutation of same or different gene.  

Two groups with same complementation have failed to complement each other.  

Thus, two wingless flies will have the same genotype i.e “ww”

When two wingless flies are crossed following offspring are produced  

ww * ww  

ww, ww, ww, ww

All the offspring are wingless too

________ drugs relax smooth muscle in the walls of the arteries, cause the arteries to dilate, and are used to treat hypertensio
Vikki [24]

Answer:

Peripheral vasodilators

Explanation:

Peripheral dilators are a form of vasodilators that are involved in the dilation of the most distal parts of the vascular system such as the venules and arterioles. It does this by relaxing the smooth muscle of the blood vessels that are wide open, therefore making it easier for the heart to pump blood through  blood vessels and also the whole body.

In the treatment of hypertension, the peripheral dilators lower blood pressure by decreasing the total peripheral resistance of the arteries. In addition to the treatment of hypertension, they are also used in the treatment of heart failure and acute myocardial infarction.

An example is isoxsuprine.

Starch molecules are hydrolyzed into smaller units knows as
vampirchik [111]
Starches are known as polysaccharides. If we look at the word "polysaccharide" poly means "many" and saccharide means "sugar" so we can infer that a polysaccharide is a molecule composed of many sugars. We can also refer to starches as complex meaning that they are composed of simpler subunits. Those subunits are simple sugars (AKA monosaccharides) such as glucose, fructose, and galactose. When we hydrolyze a compound, we break it down into smaller components. Based on all of this information, hydrolyzed starches breaks it down into simple sugars such as glucose, fructose, etc. I hope the explanation is helpful.
