Which area on the earth experience the largest difference between summer and winter?
Answers
Answer:
North Pole
Explanation:
The surface of the Earth is inclined perpendicular to the sunlight (as in the left hand side of figure 2), and so receives the maximum amount of sunlight per square area. The situation is most extreme at the north and south poles. At the north pole, the season is one long,cold night which last for six months.

Gametes (sex cells) in the flower require nutrients from the soil to ensure proper functioning. Which list of systems below best describes the interaction in that statement?
Answers
Answer:
There is a great interaction between reproductive stage and absorption of nutrients.
Explanation:
Good interaction of reproductive stage and absorption of nutrients from the soil is very important for producing good and healthy flowers because reproductive stage needs nutrients. If these nutrients can't available in the soil so the plant produced less flowers and as a result less seeds are produced in the end of this reproductive stage so we can say that reproductive stage and absorption of nutrients has a great interaction between each other.
Which function of the integumentary system is illustrated in the release of sweat? A. Absorption B. Protection C. Sensory Reception D. Regulation E. Secretion F. Both regulation and secretion
Answers
Answer:
F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Ou just read an article on the Endosymbiotic Theory. Based on what you read, what is the importance of the Endosymbiotic Theory?
Answers
Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.
Explanation:
According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.
The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:
1. The chloroplast and mitochondria have circular DNA like bacteria.
2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.
Answer:
The Endosymbiotic Theory states that the mitochondrion and chloroplasts were consumed by a cell and now depend on one another to survive. Endosymbiotic Theory helps us by giving us the technology to use forensic sciences to solve cold cases.

B. Cover crops help remove pollution from the soil.
C. Uncovered soil is easily eroded by wind and water.
D. Cover crops sell for more money that farmers can then use to invest in new soil.
Answers
Answer:
A. plants take up nutrients from soil.
Explanation:
A cover crop slows the velocity of runoff from rainfall and snowmelt, reducing soil loss due to sheet and rill erosion. Over time, a cover crop regimen will increase soil organic matter, leading to improvements in soil structure, stability, and increased moisture and nutrient holding capacity for plant growth.

Your baby is type B blood. You are type A blood. You think your significant other is type A blood. Is your significant other faithful? Explain using a Punnett square how you know.
Answers
Here is some info from the red cross...Universal donors are those with an O negative blood type. Why? O negative blood can be used in transfusions for any blood type.
Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood.
Types O negative and O positive are in high demand. Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population).
The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood. For more about plasma donation, visit the plasma donation facts. There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death.
Every 2 seconds someone in the US needs a blood transfusion.
Use the interactive graphic below to learn more about matching blood types for transfusions.
Also, Rh-negative blood is given to Rh-negative patients, and Rh-positive or Rh-negative blood may be given to Rh-positive patients. The rules for plasma are the reverse.

Explanation:
An offspring cannot have a trait if neither of its parents have it. Do you agree or disagree with this statement now? What evidence supports your ideas about the statement?
Answers
No
An offspring can have traits that neither parents have. People have both dominant and recessive genes that control the traits that they have. So the child would have gotten two recessive genes that the parents carry, to display a trait that the parents don’t display.
It can be carried to you when the chromosomes combine even if the parents don't possess the same trait. It can skip and be dominant for you, so you would be able to see it in your genetic make up.
No, I don't agree with this statement.

Explain how an biotic factor (stronger storms, warmer oceans, or lower ocean pH) can affect populations in a coral reef ecosystem
Answers
Not only is the biota important, but the abiotic factors in the ocean are also important because both groups work together. The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize.
Answer:
Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.

A male with hemophilia (recessive, sex-linked) and a female who is normal (no hemophilia) have a girl? What is the likelihood that a girl will have the disorder?
a - 0%
b - 50%
c - 100%
d - Impossible to tell
Answers
Answer:
Option A is the correct answer.
- 0%
Explanation:
This is because the male is hemophilia recessive, not dorminant and the female allele has no traits of hemophilia therefore, the offspring have zero percent of having the diseases. The girl allele will be normal and recessive of hemophilia. Because there is no dorminant allele that can result into hemophilia.

Calculate the population of 217 bison at the end of 2 years if it decreases at a rate of 7.5% per year. _____ bison
Answers
7.5% of 217 = 16.275
At end of 1 year bisons = 217 - 16.275 = 200.725
7.5% of 200.725 = 15.054375
At end of 2 years bisons = 200.725 - 15.054375 = 185.670625 (Rounding that to the tens)
=186
(P is the initial amount of bison, which is 217)
(Also, make 7.5% negative to represenr population decay, not growth. Next, convert 7.5% to decimal form: 7.5/100 = .075)
Solve:
1. Bison = 217e^(-.075)(2)
2. Bison = 186.77 bison,
Since we can’t have .77 of a bison XD) and depending on rounding, you can have 186 or 187 bison!
Good luck!
