Gestational diabetes occurs when a pregnant woman has high levels of blood sugar. Cells in the pancreas usually keep blood sugar levels normal, but hormones produced during pregnancy deactivate the cells. After pregnancy, hormone levels return to normal, and so do the pancreas cells. Is this an example of DNA or the environment controlling gene expression? Explain your answer
Answer:
environment controlling gene expression
Explanation:
Gestational diabetes generally occurs in pregnant women. The sugar level in the bloodstream becomes little high than the normal range during pregnancy. But the glucose level returns to normal after child birth.
The pancreas secrets insulin which helps to lower the blood sugar level in the body. But during pregnancy, the placenta releases some of the hormones which dilutes the effect of insulin. This is known as insulin resistance. So now the pancreas secretes more of insulin to overcome this insulin resistance for the body. Now if a woman during pregnancy does secrete more insulin, the glucose level increases in the body and the woman develops gestational diabetes.
Gestational diabetes greatly depends upon obesity and the ethnicity of the women, but a definite genetic link has not been identified.
This it is a result of the environment control gene expression.

Is the fossil record complete for humpback whales? Explain your answer.

No, the fossil record is not complete because with further fossil discoveries, and more study, it may continue to tell paleontologists how modern whales came to behave the way they do.

5. Describe what occurs at mid-ocean ridges
Answer:
6. Find the Nazca plate and the South American plate. How are they different? Are they moving toward or away from each other?
Answer:
7. How is the Nazca plate moving in relation to the Pacific plate?
Answer:
8. How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? How are they different?
Answer:
Answer:
5. when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent
6.They are moving toward each other
7. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise
8.Convection currents in the mantle drive plate tectonics. Convection is the reason for ocean currents. Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.
Both the mantle and ocean experience the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.

Given the diagram below, which of the following ordered pairs represents the
vertex, A?
O A. (b cosc, b sinC)
O B. (b cos C, c sinc)
O C. (a cosB, a sinB)
O D. (a cosc, b sinC)
Answer:c
Explanation:because cosin of b is c
(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.
What is Vertex ?In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.
In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.
Hence option D is correct.

A. simple osmosis
B. active transport
C. simple diffusion
D. facilitated diffusion and please give a reason why you chose this answer
Answer:
B. active transport
Explanation:

b
Explanation:
because active transport obey the concentration gradient..
When the water availability of a plant's environment decreases, the plant can respond by closing its stomata. This reduces the amount of water that the plant loses through its leaves due to transpiration. Closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in A. a decreased rate of photosynthesis. B. no change in the cellular processes of the plant. C. an increased rate of photosynthesis. D. an increased rate of cellular respiration.
Answer:
A. a decreased rate of photosynthesis.
Explanation:
Stomata is a structure in the leaves of higher plants, which they use majorly for the purpose of gas exchange. However, the process whereby plant loses water called transpiration also occurs via the stomata. In a situation whereby the availability of water in a plant's environment is low, the plant responds by closing its stomata in order to conserve water (reduce the amount of water that the plant loses through its leaves due to transpiration).
Closing the stomata by plants means not allowing ample carbon dioxide (CO2), which is needed for the process of photosynthesis to occur, to enter the plant. This will most likely result in a DECREASED RATE OF PHOTOSYNTHESIS.

An apple farmer notices that two of his trees produce particularly sweet apples. The farmer thinks that these sweeter apples would sell very well andcould make him a lot of money. He uses a Q-tip to pollinate the flowers of the sweet apple tree with pollen from the other sweet apple tree's flowers. He then takes the seeds from the fruit that they produce and grows a new field of trees from them. Almost all of these new trees make very sweet apples like the first two trees did.
Answer:
It is a right method for making a variety.
Explanation:
This is the right method for making sweet apples variety because in apple, cross pollination occurs and for making a new variety self pollination is the best way to prevent impurities in making a new variety. Due to self pollination, the farmer gain the sweet apple variety which help them to make more money by selling these sweet apple because of its demand.
