The pituitary gland controls the thyroid gland.
True
False

Answers

Answer 1

Answer: While the pituitary gland is the master gand of the endocrine system, it controls the thyroid gland.

The pituitary gland can be found in the base of the brain, inferior to the hypothalamus. It is considered the gland that oversees the other endocrine organ glands. It regulates, control and manages every major gland in the body.

In geometry, a pyramid is a polyhedron that is constructed when the polygonal base is connected to an iconic surface. The base edge and apex form a triangle that is called a lateral face. A pyramid can also be with an n-sided base that has n + 1 vertices, n + 1 faces, and 2n edges.

But the first thing to do is to get the number of oranges in each phases of the four-sided pyramid. To do this, we square the root the numbers of the vertices.

1 squared = 1 [for the first phase of the pyramid]

2 squared =4 [we got 4 as our answer for the second layer of the pyramid]

3 squared = 9 [9, for the third phase of pyramid]

4 squared = 16

5 squared = 25

6 squared = 36 [and 36 is the last in the pyramid]

The addition of the total oranges in each phase of the six layers is 91.

The total number of oranges in the pile = 1+4+9+16+25+36=91

Seed _____ is when enzymes and other chemicals are activated and energy is produced to start cell division.

Answers

Seed germination happens when enzymes and other chemicals become active and energy is already produced to start cell division. Germination alone, also refers to the process wherein a plant grows from the seed. The seedling that sprouts from the seed is one of the basic example of seed germination. The growth of seeds are affected by some environmental factors such as the quantity of water, the temperature and the place where the seed is sown and of course the amount of sunlight that the seed gets is very important.

Which is one way that a freshwater wetland differs from a lake or pond?

Answers

Below are supposed to be the choices:

A. water flows in a lake or pond but never flows in a wetland.
B. Wetlands are nesting areas for birds, but lakes and ponds are not.
C. Water does not always cover a wetland as it does a lake or pond.
D. Wetlands are salty, but lakes and ponds are fresh.

The answer is C. Hope it helps.

Lake and ponds are standing water.

Further Explanation:

Wetlands are the areas of marsh, peatland or water. It can be natural or artificial, permanent or temporary with water; static or flowing.

The characteristics of wetlands are-:

1. An abundance of water and prolonged saturation of the same.

2. Wetland vegetation have special adaptation for life in permanently or seasonally saturated soils.

3. The saturated soil forms distinct and visible characteristics.

Wetlands are often found alongside the waterways and also in floodplains. Wetlands may vary widely due to difference in soil, topography , the chemistry of water and vegetation. Several smaller wetland types may give rise to large wetlands.

Many wetlands found in rocky mountains regions dry up.

Lake and ponds: The characteristics feature are:

Ponds are shallow enough to allow the growth of plants across entire surface. The area where plants can grow is known as photic zone. In contrast to ponds the lakes has aphotic zone.

Ammonia can be produced by what two processes

Answers

Answer:

transamination followed by deamination

Explanation:

Ammonia exists as ammonium ion (NH4+) at the physiological pH and is produced in our body mainly by the process of transamination followed by deamination, from biogenic amines, from amino groups of nitrogenous bases like purine and pyrimidine, and in the intestine by intestinal bacterial flora through the action of

Most energy enters ecosystems in the form of sunlight.
a. True
b. False

Answers

True. Many plants, bacteria and algae rely on sunlight to get the energy they need to produce food.

True.

Energy comes from the sunlight and plants uses it for food through the process called photosynthesis.

A farmer sprays insecticide on his crops to kill unwanted insects. Most of the insects die, and the chemicals have the effect of damaging the DNA of the insects that are not killed. Which of these has happened?A. Sexual selection among the insects has changed the gene pool.
B. Genetic equilibrium has been maintained.
C. Mutations have arisen that may have altered allele frequencies.
D. Individuals with new genes have immigrated into the population.

Answers

The correct answer is option C, Mutations have arisen that may have altered allele frequencies

There have been several instances where mutation in the gene of an insect is caused due to the harmful external environmental condition which are either created or occurs naturally. Usually, the organisms evolve themselves to sustain in an adverse environment condition. In the process of evolution, they go through the process of positive genetic mutation but sometimes the mutation may also produce negative effect on the DNA of an species through wrong or inefficient pairing/coding. Here in this case it can be stated that the chemical sprayed on insects might have attacked the gene pool of the insects thereby producing adverse genetic mutation.

When a farmer sprays insecticide on crops, the DNA of the insects that are not killed can be damaged, leading to mutations that may alter allele frequencies in the population.

A farmer spraying insecticide on his crops to kill unwanted insects has the effect of damaging the DNA of the insects that are not killed. This can lead to mutations that may alter allele frequencies in the insect population. Hence, the correct answer is C. Mutations have arisen that may have altered allele frequencies.
