Which is one place that glaciers are found?
A) in the ocean
B) in the tropics
C) at low altitudes
D) at high latitudes
Answer:
I believe it is at high latitudes
Explanation:
I say this because many glaciers are found in Greenland and Antarctica which are both located in higher latitudes
Glaciers are found at HIGH latitudes (Option D).
Latitude refers to the geographic coordinates which are used to indicate specific north-south positions on the Earth's planet.
Low latitudes are geographic coordinates found between the 0 degrees (Equator) and 30 degrees north-south, whereas high latitudes are found between 30 degrees and 90 degrees north-south positions.
At low latitudes, the energy from the sun is able to melt the polar ice.
Thus, glaciers are found at high latitudes because the highest latitudes get a minor amount of energy from the sun compared to low latitudes.
In conclusion, glaciers are found at HIGH latitudes (Option D).

Which statement correctly compares metaphase I and metaphase II?
A) in metaphase 2 twice as many chromosomes line up along the middle of the cell as I’m metaphase 1.
B) in metaphase 1 twice as many chromosomes line up along the middle of the cell as in metaphase 2
C) in metaphase 2 twice as many chromosomes are pulled to opposite ends of the cell as in metaphase 1
D) In metaphase 1 twice as many chromosomes are pulled to opposite ends of the cell as in metaphase 2
Answer:
B
Explanation:
The correct answer would be that in metaphase 1 twice as many chromosomes line up along the middle of the cell as in metaphase 2.
Metaphase generally involves the formation of the metaphase plate and the alignment of chromosomes at the equator of the cell.
At metaphase I, chromosomes align as homologous pairs as opposed to metaphase II where chromosomes align at the equatorial plate singly. It thus means that twice as many chromosomes line up at the equatorial plate in metaphase I when compared to metaphase II.
The correct option is B.
Answer:
B.
I hope this helps :)
Explanation:
Metaphase I -The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.
Metaphase II-The second stage in meiosis II after prophase II, and highlights the alignment of chromosomes along a single plane in the center of the cell.

The hydrolysis of GTP to GDP carried out by tubulin molecules Group of answer choices provides the energy needed for tubulin to polymerize. occurs because the pool of free GDP has run out. tips the balance in favor of microtubule assembly. allows the behavior of microtubules called dynamic instability.
Answer:
allows the behavior of microtubules called dynamic instability.
Explanation:
GTP help to stabilize the tip of the microtubule, thereby allowing more monomers to be added.
The hydrolyses of GTP to GDP carried out in the tubulin molecules allows the behavior of microtubules called dynamic instability.GTP hydrolysis changes the conformation of the tubulin molecules and cause the dynamic behavior of microtubules because it allows the cell to rapidly reorganize the cytoskeleton when necessary in which individual microtubules alternate between cycles of growth and shrinkage.
The _____ law of thermodynamics states that not all energy is used because _____. A.) first; some of the energy disperses as heat b.)second; some of the energy is destroyed c.)first; some of the energy is destroyed second; d.)some of the energy disperses as heat
Answer:
second)some of the energy disperses as heat
Explanation:
This second law of thermodynamics states that in the course of conversion of energy from one form to another in an organisms,this can not be 100% efficient ( there is constant increase in entropy of the systems in the organism)as some of the energy is dissipated as heat in the course of conversion.
Thus in a food chain as energy is been converted from one trophic level( primary consumer) to another( secondary consumer) these organism makes use of the energy to do biologic work.Therefore as this is passed to other organism in the tropic levels not all the initial energy will be available ,as some has been lost during biology work,respiration , excretion ,movements and locomotion. in the subsequent organisms.
Thus the entropy of the organisms involved increases as energy is been transmitted from one trophic level to another which leads to heat dispassion.

Henry was studying two populations of the same species of lizards. One population lived on an island and the other lived on the mainland. Both populations were affected by a hurricane that hit the island and the mainland with equal force. A year later, Henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. Which best describes a conclusion he might have reached? Gene flow greatly affects small populations, but large populations can recover. Genetic drift greatly affects small populations, but large populations can recover. Gene flow greatly affects large populations, but small populations can recover. Genetic drift greatly affects large populations, but small populations can recover.
Answer:
The correct option is Genetic drift greatly affects small populations, but large populations can recover.
Explanation:
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population.
Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly attach one of the alleles.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
In the exposed example, the hurricane caused a disaster in both populations, reducing the number of individuals on the island and in the mainland. Henry saw a decrease in genetic variation in the island species, but not in the mainland species. This could be because the island population was smaller than the mainland population, so it was more affected by the disaster. The loss of some alleles in the population caused a decrease in genetic variation in the island population.

A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all.
Answer:
C
Explanation:
The complete question: A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all. In the experiment described in the scenario, which group represents the control group? A. Plant B B. Plant A C. Plant D D. Plant C?
The control group here would be plant D.
Control groups are usually used to minimize the effects of extraneous variables in the course of experiments and to ensure that the differences observed in different experimental groups are due to the effects of the independent variables.
In this case, all the plants were exposed to music except the control group because the aim of the experiment is to measure the effects of music on plant growth. Any difference in growth observed between those exposed to music and the control group can reliably be considered to be due to the music.
The correct option is C.

Dr. DeRidder lesions, or damages, the ventromedial hypothalamus in one group of rats and the lateral hypothalamus in another group. What effect might he expect on the eating behavior of each group of rats? Both groups should begin overeating and become grossly obese. Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating. Both groups should stop eating and perhaps eventually starve to death. Rats with ventromedial lesions should stop eating; rats with lateral lesions should begin overeating.
Answer:
Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating
Explanation:
The feeling of hunger stimulates a desire to eat.
The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.
A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.
On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.
