Answer:

Body temperature

Explanation:

We use body temperature as homeostasis parameter in the lab.

Homeostasis can be described as a self regulating mechanism used by the body systems for stability maintainable so as to adjust to several conditions that are important for survival.

The way the body controls the body temperature in humans is a good description of homeostasis

Answer:

See the answer below

Explanation:

Using the formula for calculating Chi square ( $X^2$ ):

$X^2$ = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency.

The observed frequencies for the four phenotypes are 88, 62, 62, and 81 respectively.

For the expected frequency, the phenotypes are supposed to assort in 9:3:3:1 according to Mendel ratio.

Hence, expected frequencies are calculated as:

phenotype (1) = 9/16 x 293 = 164.81

phenotype (2) = 3/16 x 293 = 54.94

phenotype (3) = 3/16 x 293 = 54.94

phenotype (4) = 1/16 x 293 = 18.31

The $X^2$ is calculated thus:

Phenotype O E $X^2$

1 88 164.81 $\frac{(88 - 164.81)^2}{164.81}$ = 35.80

2 62 54.94 $\frac{(62 - 54.94)^2}{54.94}$ = 0.91

3 62 54.94 $\frac{(62 - 54.94)^2}{54.94}$ = 0.91

4 81 18.31 $\frac{(81 - 18.31)^2}{18.31}$ = 214.64

Total $X^2$ = 35.80 + 0.91 + 0.91 + 214.64 = 252.26

To the nearest tenth = 252

Degree of freedom = n - 1 = 4- 1 = 3

$X^2$ tabulated = 7.815

The calculated  $X^2$  exceeds the critical value, hence, the null hypothesis is rejected. The two genes did not assort independently.

exis [7]

I think it might be possible because they took the nucleus from a sheep and put it inside a sheep embryo and it made an exact clone of the sheep.If they could make a nucleus that could handle the DNA of the dinosaurs and have the nucleus function properly and have the embryo grow properly then it might be possible for them to create dinosaurs.

A leaf in which small veins extend outward from a single main veins has what type of ventaion?

e-lub [12.9K]

Well...This might helps Parallel venation is characteristic of monocots, the veins are usually parallel to each other along the length of the leaf. 
Pinnate venation is the veins are in a branching pattern, characterized by one major vein(called midrib) with smaller veins extending outward from it.
Palmate venation is characterized by two or more major veins extending outward from one point like the fingers extending form the palm of a hand

How cellular respiration relates to law of thermodynamics???

Butoxors [25]

Answer:

First Law of Thermodynamics in Biological Systems

All biological organisms require energy to survive. ... The chemical energy is stored in the form of glucose, which is used to form complex carbohydrates necessary to build plant mass. The energy stored in glucose can also be released through cellular respiration.
