What is the observable change in the allele frequencies of a population over time called?

Imagine that you're able to fully dissolve a powdered substance in water. What can be said about this creation?

V125BC [204]

We can say that the water is the solvent, and the powder is the solute. This is also a solution altogether.

<span>Explanation:- A solute is the thing being dissolved into the solvent. While the solvent is what when the solute is being dissolved in. Together, they make a solution. </span>

In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

When under the influence of alcohol, muscle ___________ is slow and errors are made in interpreting speed?

evablogger [386]

When under the influence of alcohol, muscle COORDINATION is slow and errors are made in interpreting speed. Muscle coordination refers to the complex coordinated movement of muscles with little conscious efforts. This ability is always drastically reduced in individuals who are driving after taking alcohol.

Which statement best describes enzymes?

Nuetrik [128]

Answer:

The rate of activity of an enzyme might change as pH changes

Explanation:

Enzymes are organic catalysts that controls the rate of a specific chemical reaction.

These materials combines substrates in order to lower the activation energy which might serves as a barrier to chemical action.

Enzymes have specific reactions which they control.
Temperature and PH conditions control the rate at which enzymes work.
They are not all produced from the building block of carbohydrates.
