Answer:
Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.
The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense and begins to rise. The cooler and denser air mass from the poles rushes in, through the lower atmosphere, to replace the void of the rising air.
When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.
The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.

Answer:
C. 1/4
Explanation:
Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=
9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.
Therefore, the proportion of the progeny with long horns = 4/16= 1/4
Can I see the picture please?
Just by reading the answers it seems like the correct one would be A, but i would like to double check.
Answer:
Dr. Siddiqui asks you what you think is wrong with Angela. What is your diagnosis? (Note: do not simplysay hyper- or hypothyroidism; that portion of the question was already answered above. Explain in detailwhy/how you came up with the diagnosis. Include the evidence that led you to this diagnosis.
Judging from Angela’s results, she has Serum thyroxine, Thyrotropin, and SerumTriiodothyronine hormones to be missing. This will cause Hypothyroidism results due to failure of the thyroid gland to produce sufficient hormones.
Angela does not have a goiter at the moment. If her condition continues unchecked will she develop one?Why or why not? Make sure you include information from Angela’s blood work results to back up yourresponse.
Technically, a goiter can develop in a gland that is developing high level of hormone (hyperthyroidism), and low level of hormone (hypothyroidism), or the certain amount of hormone (euthyroidism) needed.
In Angela’s situation, her TSH concentration and thyroid hormones are at a reduced level. This will cause, the pituitary gland in the brain to produce a signal to the thyroid. Thus, her condition should be well observed all through the period till her conditions return to the way it ought to be normally.
Answer: physiological
When we are under constant stress, our body will start expressing it with physiological responses. When the body realizes the presence of the stressor agent, sends signals to the hypothalamus, and it activates the sympathetic and hormonal
responses to eliminate the stress.
The digestive tract is a part of the body very commonly affected by stress.
