The poles never get any direct sunlight.
They both get the same amount of sunlight.
Because they receive no direct sunshine, the Arctic (North Pole) and Antarctic (South Pole) are both chilly. Even at the height of summer, the Sun is low on the horizon. The Sun doesn't rise at all for several months during the winter since it is so deep below the horizon hence poles don't have equal amounts of sunlight and darkness.The poles receive less energy and heat from the sun because of the tilt of the earth and its orbit around the sun. There are just two polar seasons as a result: summer and winter.The tilt of the Earth's axis causes the Poles to experience around six months of day and six months of night. Due to this tilt, each Pole spends roughly six months angled both toward and away from the Sun. The North Pole experiences six months of nonstop daylight when it is inclined toward the Sun.In the winter, the Sun sets for extended periods of time since it is so deep below the horizon. Therefore, the days are chilly and dark, much like the nights. The South Pole and North Pole receive the same amount of sunshine despite being "polar opposites."learn more about poles here: https://brainly.com/question/1776073

explain in steps how a tree trunk gets wider
Answer:
The first thing that determines the thickness of a tree trunk is the species. Some kinds of trees just naturally have a different trunk thickness than others.
The second thing might be the environment. A tree that is experiencing all factors - sun, water, soil, minerals - at an optimum level is going to grow faster, taller, stronger, and thicker than the same species in a less-optimum environment.
A third factor is time. As time passes, the tree trunk increases in diameter - thus a tree that is 50 years old will have a much thicker trunk than one that is 5 year old.
And, in case you’re wondering why or how tree trunks increase in thickness at all, there is a thin layer of cells all around the trunk of a tree, like a sheet that lives under the bark. This layer is called the cambium layer which makes new living tissue for the tree (called phloem and xylem) every year. As the year’s growth comes to an end, the living tissue dies and is pushed outward to appear as bark by the new year’s sheet of cambium cells, which is bigger than the previous year’s - hence, the increase in diameter of the tree every year.

Which results from an increase in the greenhouse effect?
Answer:
nitrogen?
Explanation:
Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes Earth to warm up.
Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.

Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.
What does this information best demonstrate?
A.
Cells interact with other cells for regulation and homeostasis.
B.
A hormone is a protein that performs many functions in the body.
C.
Only certain cells can use glucose to produce energy.
D.
Beta cells are not necessary for glucose to be utilized.
The best-demonstrated information is
A. Cells interact with other cells for regulation and homeostasis.
C. Only certain cells can use glucose to produce energy.
One of the important hormones in the human body is insulin. How the human body uses food to meet its energy needs is explained by knowledge of insulin and its workings.
Typically, food-derived glucose that enters the bloodstream is what causes blood sugar levels to rise. The pancreas is a gland that aids in the release of insulin to regulate blood sugar levels. Based on the blood sugar level, insulin often releases itself in a feedback system.
The insulin mechanism best exemplifies the following:
Together with glucagon, insulin contributes to the maintenance of the constant condition known as homeostasis in the human body.Considered essential for cells to use glucose and obtain energy is insulin.As a result, the mechanism of insulin in the human body shows how various cells use energy and how insulin is crucial for preserving homeostasis.

What is true about the thickness of the ozone layer?
It has gradually decreased in the last couple of years.
It has remained the same in the last couple of years.
It has entirely disappeared in the last couple of years.
It has gradually increased in the last couple of years.
Answer:
A
Explanation:
The top answer is correct, over time it has become weaker.
Answer: The answer is A (It has gradually decreased in the last couple of years)
Over the Earth's surface, the ozone layer's average thickness is about 300 Dobson Units, or a layer that is 3 millimeters thick.The thickness of the ozone layer changes due to increasing concentrations of ozone-depleting substances in the atmosphere.Air motions also increase the ver- tical thickness of the ozone layer near the poles, which increases the value of total ozone in those regions. Tropospheric weather systems can temporarily reduce the thickness of the stratospheric ozone layer in a region, low- ering total ozone at the same time.It is thinning due to the release of man-made compounds called chlorofluorocarbons (CFC). The net effect that CFCs have on the ozone layer is to recombine an oxygen atom with an ozone molecule to form two oxygen molecules.

Of the following choices, what is the approximate LD50 of the least toxic substance? 20 mg/kg, 70 mg/kg, or 130 mg/kg
The approximate LD50 of the least toxic substance will be 130 mg/Kg.
The dose necessary to cause the death of 50% of a population under test after a predetermined test period is known as the LD50 value for a drug. Commonly used as a broad indicator of a substance's acute toxicity are LD50 values. Greater toxicity is indicated by a lower LD50. A low LD50 of 500 mg/kg or less implies severe toxicity. Moderate toxicity is indicated by an LD50 of 500 to 1,000 mg/kg. A modest toxicity level of 1,000 to 2,000 mg/kg is indicated.The species is especially vulnerable to the poison if the LD50 is low.

Huntington's disease characterizes for being,
Hereditary, passing from generation to generation. To express the disease the person must have been born with an altered gene.Autosomal, affecting men and women equally because the mutated gene is located on an autosomal chromosome.
Dominant, meaning that by inheriting only one copy of the altered gene from any of the parents, the receiving person will express the disease.
