plz help!!!!!!!! A natural biological cooling process is sweating. Using your knowledge of endothermic and exothermic, explain why your body feels cooler when it sweats.
Answer and Explanation:
An exothermic reaction takes place when heat flows out of a system into its surroundings. ... When you sweat, the system – your body – cools down as perspiration evaporates from the skin and heat flows to the surrounding area. This means sweating is an exothermic reaction.

the donor blood type considered to be universal
Answer:
O negative blood
Explanation:
For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it's sometimes called the universal blood donor type.
HOPE IT HELPS :)
PLEASE MARK IT THE BRAINLIEST!
Answer:
type O
Explanation:
type O, since it contains no antigens. Type O, negative, to be more speciifc (with negative referring to the Rh factor) however O Negative Is widely considered the universal blood type. It is very important because it potentially be transfused to any patient regardless of their blood type. Especially in emergency situations, when there isn't enough time to determine a patients blood type. A person with type O - is considered to be a universal donor because his blood can be safely received by a person with type A, B, AB, or O.

function of a mitochondion
Answer:
mitochondria are to produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.
Explanation:
the role of mitochondrion is to generate the energy commodity of the cell, by respiration, and control of cell metabolism.Mitochondrial is the ATP synthesis site for the cell. The amount of mitochondria present in a cell is also a strong predictor of the cell 's rate of metabolic activity; cells that are very metabolically active, such as hepatocytes, may have more mitochondria.

how does the virus use a host cell to make copies of itself
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

Which of the following is the most effective public policy in reducing reliance on fossil fuels in the long run?
A. Forging strategic alliances with oil producing nations
B. Investing in renewable fuel technologies
C. Offering business incentives for reducing use
D. Producing more fossil fuels
E. Rewarding reductions in current personal use
Answer:
b
Explanation:
as time goes on it could be possible with new found ways to never again need the fossil fuels
There are different kinds of investment. The option that is the most effective public policy in reducing reliance on fossil fuels in the long run is Investing in renewable fuel technologies.
Renewable energy sources is known to give the best way to fulfill the energy needs of the world. While fossil fuels is known to be soon depleted and therefore renewable energy sources are always there.
It is therefore smart to invest in renewable energy as the capability to store renewable power for use when needed makes it better than alternative to fossil fuels.
Investing in renewable energy stocks is known to helps man in spreading one's wings and can bring about a lot of dividend income.

A student is measuring plant growth in an experiment. Using the same species of plant, he places one plant in the dark and one in artificial light. He
hypothesizes that, over time, the plant in the artificial light will grow larger than the plant in the dark. What is the dependent variable in this
experiment?
-Artificial light
-Plant growth over time
-Species of plant
-Time in light versus dark
Answer: Plant growth over time
Explanation:
i would say that because its very likely that the growth of the plant will change, the rest of them seem like a independent variable. Have a good day hope i helped.

Which distribution pattern do the oyster larvae exhibit?
O A. clumped
OB. stationary
C. random
OD. uniform
Answer:
D. Random
Explanation:
The term "population distribution pattern" refers to the method or form in which population of a certain organism living in a certain area occupy that area.
For example:
Uniform distribution pattern in which organisms are arranged in a equal or regular manner in the area. This gives a competition to the organisms of the area with reference to each other.
If we talk about Oysters, they are able to travel many and many kilometers across a certain area. Therefore, they don't stay at a place in a regular manner and this gives them random distribution pattern.
Hope this helps you.. Good luck!
BIOLOGY EXPERTS!!!! Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.
Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.
Explanation:
The following are the shared core processes shared by all eukaryotes.:
1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.
2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.
The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.
