2. What is the relationship between air temperature and air pressure at the
equator?
Answer:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.
the pressure patterns associated with global circulation patterns. On the equator areas, since air is heated and rises, a zone of lower pressure will result.
Explanation:
mark it as brainliest. thnku hope it is helpful.
Explanation:
at the equator the air is moist and hot and when air is hot it's density decreases and so does the pressure exerted by it. and also air that contains water vapour is less denser than the air containing no or less water vapour so air containing less water vapour exerts more pressure
Ou just read an article on the Endosymbiotic Theory. Based on what you read, what is the importance of the Endosymbiotic Theory?
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.

You are concerned that your significant other cheated on you and they are not the mother/father of the baby! Luckily for you, you know all about blood typing and how it works. 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.
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.
Answer:
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.

A young child does something he knows is wrong and immediately looks at an adult for a reaction. This child has learned to?
Answer:
This child has learned to act from its adults.
Explanation:
This child has learned to act according to the reaction of the adult. If a child done something wrong and the adult reaction is not good the child will not repeat it because he knows that this act is bad while on the other hand, when the child done something good and the adult gives a good reaction so the child will continue doing this action so we can say that a child learn most of the things from their adults.

An ecosystem experiences a volcanic eruption that covers the area with lava. Which of the following organisms is most likely to be a
pioneer species in this ecosystem?
Answer:B
Explanation
to be completely honesty i have no knowledge if learning the current benefactor of the object asked in this particular question.
An ecosystem experiences a volcanic eruption that covers the area with lava. Organisms moss is most likely to be a pioneer species in this ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes.

Which area on the earth experience the largest difference between summer and winter?
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?
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.

Why does planting cover crops help conserve soil?
A. plants take up nutrients from soil.
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.
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.
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
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.
