The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

Answer:
Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

Nerve impulses are carried to another part of the body by a neuron’s:
(1) dendrites
(2) axon
(3) synapse
(4) neurotransmitter
Answer:
1.
Explanation:
Dendrites is the neuron's that receives nerve impulses and carry it to another part of the body.
Nerve impulses are the messages that are transferred from one part of the body to the another. These messages are carried across the body with the help of neuron's named dendrites.
Dendrites are branched like projections of in the nerve cell. Through these projections, message passes across the body.
Therefore, option 1 is correct.
Will give brainliest If you increase the rainfall across the region that the Buffalo are in, how do you think that would affect the carrying capacity for Buffalo in the ecosystem?
Answer:
The Buffalos carrying capacity would most likely go down if the water supply increases.
Explanation:
If water supply increases Buffalos would have easier access to water. example: instead of getting new water every month or so when it rained they can get water anytime due to the increased supply.
The "Buffalos-carrying" capacity would most likely go down" if, the water supply increases," If water supply increases Buffalos would have easier access to water".
Did a change in temperature cause the buffalo population to increase?Buffalo does shift in regard to the environment because if the climate impacts the carrying-capacity, by involving the resources.
If "the carrying-capacity goes up or down then the people of buffalos would up or down "with it. Although it does not impact the population much.

An mRNA that is readily transported into cytoplasm should have all of the following
EXCEPT
a. exons
b. a poly-A tail
c. a 5’-cap
d. introns
Explanation:
In eukaryotic cells, pre-mRNA has to undergo 3 stages of RNA processing before being transported into the cytosol. Specifically during RNA Splicing, small nuclear RNAs (snRNAs), small nuclear ribonucleoproteins (snRNPs) and other proteins form a spliceosome which excises introns and splice together exons. Introns are considered junk material and does not stay with the mRNA.
The answer is Introns. (D)

Which is the final electron acceptor in the electron transport chain of cellular respiration?
Answer:
Oxygen.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Oxygen is the final electron acceptor in the electron transport chain of cellular respiration. The oxygen accepts electron when it passes through ATPase and the electron transport chain of cellular respiration.

Two species of fish are introduced to the same lake. Over time, only one species survives. According to Darwin's theory of evolution, what should characterize the surviving species
Answer: Both species must have competed for the same niche. The surviving species is better adapted or adapted better and outcompeted the other.
Explanation:
According to Darwin's theory of evolution (survival of the fittest), the surviving species would be fitter than the extinct fish.
What is the theory of survival of the fittest?Charles Darwin proposed the idea of the "survival of the fittest," which states that organisms that are most adapted to their environment have a higher chance of surviving and reproducing. Charles Darwin proposed natural selection as a crucial aspect of evolution.
Natural selection refers to the process by which an organism becomes more likely to thrive and produce more offspring the better it is able to get food and avoid becoming prey. The process of evolution is driven by this "survival of the fittest," which results in species surviving as a whole.
Thus, according to Darwin's theory of evolution, the surviving species would be fitter than the extinct fish.
