Which climate zone receives the lowest insolation?
A. Polar
B. Tropical
C. Temperate
The climate zone which receives the lowest insulation is the Polar climate. Thus, the correct option is A.
What is Polar zone?A polar climate is a place where the climate generally has a temperature range below freezing temperature, icy, and covered in snow from all the areas. These areas do not get any direct heat and sunlight from the sun. Polar climates are usually located at the North Pole of the Arctic, and at the South Pole on the continent of Antarctica.
The polar regions which are surrounding the Earth's North and South Poles belong to polar. The areas around the North Pole is called as the Arctic region. The area around the South Pole is called as the Antarctica region. These regions have a unique set of climates.
Therefore, the correct option is A.

In a zoo located in a warm region, which should be included in the polar bear exhibit?
A food bowl with fruit
B hot, bright lights
C cold-water pool
D tall palm trees
Answer:
C Cold - Water pool
Explanation:
The two polar bear habitats are very different and provide unique experiences for the bears to investigate. To keep the bears cool, the floors in the Ice Cave are chilled by cold water running underneath and their pools are kept between 50 - 60°F. Keepers train the bears to voluntarily take part in preventative health care.
In the two step cellular process of transcription and translation
(A) chromosomes line up and then are pulled to opposite ends of the cell.
(B) stem cells develop in embryonic cells, which then form adult tissue cells.
(C) the DNA double helix is separated and then replicated to form two strands of DNA.
(D) a DNA sequence is copied to form an RNA sequence, and then copied to form a protein.
Answer:
The answer is D
A is cell division, B is some stage of pregnancy, and C is DNA replication.
I Organisms can be dassified based on homology, which is shared characteristics inherited from a common ancestor. In the past, homologies were based on studies of anatomical structures and patterns of embryonic development. In more recent years, the use of molecular biology techniques has allowed homologies to be compared at the level of nucleotide sequences. Nucleotide sequence comparisons are possible because all organisms share which of the following?
Answer:
DNA Bases
Explanation:
It can't be cellular organelles, division of the nuclear chromosomes, and types of proteins needed for cellular functions, so the answer is DNA bases.By controlling the spread of vegetation and the balance of certain fish species, the American alligator serves as a(n) in its ecosystem.
Answer: Below
Explanation:
Alligators play an important role in maintaining ecosystem balance. Sitting at the top of the food chain, alligators are top predators and help keep other animal populations in balance. By digging holes and leaving trails throughout marshes, they create habitats for fish and marine invertebrates
What effect does the Earth spinning on its axis have on winds and currents?
The density of the water is increased causing the water to sink, forming deep ocean currents.
B) Global winds will move along a curved path and therefore cause ocean currents to curve.
Global winds will move along a straight path and will have no effect on ocean currents.
The moon's gravitational pull on the Earth is increased, causing water to move up the coast.
Answer:
B) Global winds will move along a curved path and therefore cause ocean currents to curve.
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
Basically, the effect of the Earth spinning on its axis have on winds and currents is that Global winds will move along a curved path and therefore cause ocean currents to curve. As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises. Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.
Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.

Explanation:
as the hare population increases there is in increase in the lynx population explain why this occurs
Answer: The lynx population increases as the hare population increases because there are more prey for the lynx to eat. The Lynx population also increases because there is more food for them to eat. What does the increase in the lynx population lead to? It leads to a decrease in the hare population because the lynxes were eating the hares. What happens to the lynx population when the hare population goes up? Continued predation due to high populations of lynx and other predators increases the hare population decline. ... As hare numbers start to decline, lynx continue to eat well because they can easily catch the starving hares. When hares become scarce, lynx numbers also decline.
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
The changes in the population of one species can have a significant impact on the population of another species within the same ecosystem. Therefore, when hare population increases, there is in increase in the lynx population as well.
What is predator-prey cycle?A predator-prey cycle is a cycle where if the prey population increases in size, it leads to an increase in predator population size due to availability of more food.
The relationship between the hare and lynx populations is a predator-prey dynamics. When the hare population increases in size, the lynx population also increases due to availability of more food.
When there are more number of hares, the lynx hunts them more easily which causes an increase in lynx population. However, the increase in lynx population leads to more consumption of hares, that leads to decrease in the hare population. With fewer hares available, the lynx population then starts to decline leading to a cyclical pattern of population growth and decline.
Therefore, this type of relationship is a predator-prey cycle which describes changes in the population of one species can have a significant impact on the population of another species within the same ecosystem.

Answer:
Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP (adenosine triphosphate)
Explanation:
Answer:
The purpose of cellular respiration is to transfer energy from glucose to ATP. This is important because we need energy, and we use it to move.

gynoceium with United carples is called as
Answer: Gynoceium with united Carples is know as SYNCARPOUS.
Explanation:
The vegetative organs of plants includes the stem, root and leaves. The stem which is the basic organ gives rise to other plant organs which includes the floral organs.
Floral organs are made up of:
--> sepals
--> petals
--> stamens
--> carpels
The carpel is the individual unit of the GYNOECIUM and has a stigma, style, and ovary. GYNOECIUM which is the female reproductive part of flowering plant can be monocarpous (when the carpels occurs in a single form), or apocarpous ( when there are multiple unfused carpels), or SYNCARPOUS (when there are multiple fused carpels).
Answer:
It is considered monocarpous if a gynoecium has a single carpet. If there are several distinct (free, unfused) carpets in a gynoecium, then it is apocarpal. If a gynoecium is "fused" into a single structure with several carpets, it is syncarpic.
