Define permafrost in you own words!

Answers

Answer 1

Answer:

Permafrost is ground that continuously remains below 0°C for two or more years, located on land or under the ocean. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface.

Explanation:

Answer 2

Answer: pick one

try this,

Permafrost is a permanently frozen layer on or under Earth's surface. It consists of soil, gravel, and sand, usually bound together by ice. ... Permafrost covers approximately 22.8 million square kilometers (about 8.8 million square miles) in Earth's Northern Hemisphere. Frozen ground is not always the same as permafrost.

or try this,

Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".

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.

Answers

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.

Answers

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.

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.

Jose and Rema are making sourdough bread. They have been feeding the starter dough for a week now, and it has undergone lactic acid fermentation. They mix the dough and add a portion of the starter, which will give the bread its famous texture and sour flavor. What process will occur next to make the dough rise?
A
Alcoholic fermentation takes place and ethyl alcohol and CO2 gas are formed, creating pockets in the dough.

B
Alcoholic fermentation takes place, and the yeast give off oxygen, creating pockets in the dough.

C
Alcoholic fermentation takes place, and during the Krebs cycle, CO2 is produced, creating pockets in the dough.

D
Alcoholic fermentation takes place, and the H2O byproduct of the electron transport chain vaporizes to create pockets in the dough.

Answers

Answer:

A. Alcoholic fermentation takes place and ethyl alcohol and CO2 gas are formed, creating pockets in the dough.

Explanation:

Alcoholic fermentation is a process carried out by certain organisms in the absence of oxygen. In this process, sugars such as glucose etc are broken down without oxygen into ethanol (alcohol) and carbon dioxide (CO2) by an organim called YEAST.

According to this question, Jose and Rema are making sourdough bread. The starter being fed has undergone fermentation (in the absence of oxygen). This means that the organism undergoing the fermentation produces ethyl alcohol and CO2 gas, creating pockets in the dough. Hence, making the dough to rise.

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

Answers

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.

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.
