A fertilised egg hatches into a nauplius: a one-eyed larva comprising a head and a telson, without a thorax or abdomen. This undergoes six months of growth, passing through fiveinstars, before transforming into the cyprid stage. Nauplii are typically initially brooded by the parent, and released after the first moult as larvae that swim freely using setae.[7]

If a gas is at a constant rate, what will happen to the pressure when the temperature decreases
aev [14]

Explanation:

The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.

What drug or drug class inhibits mobilization of free fatty acids from peripheral tissues?
soldier1979 [14.2K]
The drug is: Niacin, or nicotinic acid (vitamin B3, ou PP)  (do not confuse with nicotine)

Nicotinic acid, or niacin, is known for its normolipidemic properties since the 1950s. It was the subject of the first trial of cardiovascular prevention by intervention on the lipidic factor, the coronary drug project (CDP). Despite significant side effects, mainly flushing, it has since been used, mainly in the United States, as a treatment for mixed hyperlipidemias, thanks to its hypotriglyceridemic effect for the increase of HDL-cholesterol.

An individual who is heterozygous for two linked genes (with alleles A, a and B, b) is crossed with an a b/a b individual, and a
RoseWind [281]

Answer:

b) 0.30

Explanation:

An individual who is heterozygous for two linked genes (with alleles A, a and B, b)

i.e Aa & Bb × ab/ab

This cross produce the following offspring :

14 AB/ab  

36 Ab/ab  

34 aB/ab  

16 ab/ab

Now, the purpose of these calculation is to determine how close together on a gene (gene mapping) these recombinants are.

First, we need to determine the linked gene for the parental chromosomal configurations which are (Aa & Bb × ab/ab) and the recombinant configurations in the offspring which are ( AB/ab & ab/ab). This allows for the calculation of the recombinant frequency; and it is given by:  

= \frac{number of recombinant frequency}{total number of offspring}

=\frac{14+16}{14+36+34+16}

= \frac{30}{100}

= 0.3
