Answer: tight junction

Explanation:

Tight junctions are the multiprotein complexes. The function of these complexes is to prevent the leakage of the transported water and solutes. These junctions seals the pathway between two cells. These junctions form an impermeable barrier against the fluid. The tight junctions hold the cells together and are protective in nature. The tight junction are present on the epidermal cells of the skin it keeps the skin waterproof.

Population A consists of 100 hens that are fully isogenic and that are reared in a uniform environment. The average weight of th
qaws [65]

Answer:

a. the environmental variance (VE) = 3.5 g ²

b. 17.5 g ² for population

c. the heritability of broad sense (H2) = 0.83

Explanation:

a.With the information we have we can infer that environmental factors influence A, which is considered isogenic, thus, the environmental variance (VE) = 3.5 g ²

b.When studying population B, comparing it without environmental changes with respect to population A, we found that its total variance (VT) = 21.0g ²

We generate the following formula with the data obtained previously to find the genetic variation

VT = VE + VG

then VG = VT-VE

replacing data:

VG = 21.0 - 3.5 = 17.5 g ² for population

c. Regarding the heritability of broad sense (H2) in population B, we can reach the result with the data previously obtained like this:

H2 = VG / VT = 17.5 / 21.0 = 0.83

An experiment is done on 90 people to test their vitamin D levels: 30 are given vitamin D tablets, 30 are told to spend 15 minut
Jet001 [13]

Answer:

The correct answer is -

The control group: the group of people with no supplements and kept inside.

The dependent variable: Vitamin D level in all groups.

The independent variable: the source of vitamin D (sun or tablets)

Explanation:

The control group of any experiment is the group of subjects that did not receive any type of treatment or did not manipulate by the independent variable. Here the group of 30 people that kept inside and did not get supplements is the control group.

The independent variable is a variable that directly affects the dependent variable by a change in the independent variable. In this experiment, the sunlight and vitamin D tablets are independent variables that affect the vitamin D level in people.

The dependent variable is a variable that is affected by the independent variable or depends on the independent variable, vitamin level is the dependent variable.
