<h3><u>Answer;</u></h3>

Differences in heating

The flow of air caused by <u>differences in heating </u>and the Coriolis effect creates distinct wind patterns on Earth's surface.

<h3><u>Explanation</u>;</h3>
  • <u>Movement of air or flow of air is caused by pressure or temperature differences and is experienced as wind.</u> When there is a pressure difference between two places, a pressure gradient exists, across which air moves from the region of high pressure to the region of low pressure.
  • <em><u>Differences in temperature also causes movement of air or wind know as convection. The air flow caused by temperature difference is observed in the case of sea and land breezes, because of the difference in temperature between the sea and the land.</u></em>

Consider two different traits in mice affecting tail length and fur color. A two-factor cross was made involving true-breeding m
Stells [14]

Answer:

See the answer below

Explanation:

Null hypothesis: The two genes are independently assorting and therefore, are not linked to each other.

Let A represents the allele for tail length and B for fur color. Long-tail A is dominant over short tail a while brown fur B is dominant over white fur b.

For the first cross involving true-breeding mice:

    AABB   x   aabb

F1         AaBb (long tails and brown fur)

For the second cross:

      AaBb   x   aabb

4 AaBb - Long-tail, brown fur

4 Aabb - Long tail, white fur

4 aaBb - short tail, brown fur

4 aabb - short tail, white fur

Since the phenotypic ratio from the cross is 1:1:1:1, if the null hypothesis was to be true, it means that the expected phenotype ratio should be 1:1:1:1.

In order to test this hypothesis, we use Chi-square:

phenotype                           O            E                 X^2  

Long-tail, brown fur           118          97.5        \frac{(118-97.5)^2}{97.5} = 4.31

Long tail, white fur              77           97.5             4.31

short tail, brown fur             81           97.5              2.79

short tail, white fur              114           97.5              2.79

Total                                                                          14.2

Degree of freedom = 4 - 1 = 3

Critical Chi-square value = 7.815

The calculated Chi-square value is more than the critical value, hence, the null hypothesis is rejected.

What are our lungs made out of?
DanielleElmas [232]

Answer:

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopies

What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2
rusak2 [61]

Answer:

The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

Explanation:

The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.

The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.

Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:

                                 <em>C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂</em>

This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.

For the other options it is important to mention that:

  • <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place. </em>
  • <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
