The bloodstream receives oxygen from the lungs during gas exchange. Carbon dioxide leaves circulation enters the lungs. Between the alveoli and network of tiny blood arteries known as capillaries are the lungs.
What is the main function of gas exchange ?The waste gas carbon dioxide is exchanged for oxygen at each cell in your body. This waste gas is then transported by your bloodstream back to your lungs, where it is expelled after being eliminated from the bloodstream. Gas exchange, a crucial activity carried out automatically by your lungs and respiratory system, is a fundamental function.
How is gas exchange in the body?While carbon dioxide diffuses into the alveoli and is later breathed out of the body, oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body. The respiratory membrane serves as a barrier for the exchange of oxygen and carbon dioxide.

In one to two sentences, explain why there is more concern for severe storms in low-pressure systems.
The low-pressure areas have a relatively thin atmosphere and that causes air to rise fast to make clouds. Sometimes, a storm is formed due to air can't move downward towards the surface and instead, it converges. Severe storms are mostly observed in low-pressure areas because it has perfect conditions: the air is thin, high wind speeds, and rapid spiral movement. Warm ocean waters are catalysts for these storms.

Which is NOT a phraseused by Darwin to describeevolution?A. "natural selection"B. "survival of the fittest"C. "struggling for existence"D. "evolution is artificial"
Let's recall what Charles Darwin found:
He stated that natural selection plays a huge role in evolution. He claimed that organisms that had the best traits well-adapted for their specific ecosystem would be able to survive the longest (the most fitness and also known as "survival of the fittest").
Also recall what happens in an ecosystem and food webs as well as the logistical growth equation:
[tex]\frac{dN}{dt}=r_{max}N\bigg(\frac{K-N}{K}\bigg)[/tex]Ecosystems have only so many amounts of resources, or limited resources. Therefore, organisms within the same ecosystem will compete for these resources. These organisms will struggle and fight to survive. They either adapt or they get killed off.
Therefore, the best answer choice that doesn't describe Darwin's statements about evolution is answer choice D.

*Explain thoroughly how deforestation affects the fertility of the impacted land?*
Deforestation can have destructive effects on soils. Trees and shrubs shield the ground from the force of raindrops and provide shade that reduces surface soil temperature, which in turn reduces evaporation. Logging and small-scale removal of trees exposes soil to rain splash which loosens and dislodges soil particles, eroding soil and creating a more impermeable bare surface, which increases runoff.
It was found that the majority of soil fertility indices were affected negatively by deforestation and more than half of the organic matter was lost to deforestation, which, in turn, could lead to deterioration in soil quality or land productivity capacity.
True or False: Blood sugar would be lower than normal if liver cells did not have receptors for glucagon.
The answer to the statement " Blood sugar would be lower than normal if liver cells did not have receptors for glucagon " is true.
Why the blood sugar level decreases when liver cells lack receptors for glucagon?It happens that when the liver cells within our body system is short of it deficient of the
glucagon receptor, it usually, frequently and most of the time results in the decreament of the sugar in the blood volume.
However, the hormone known as the glucagon which is manufactured in the pancreas which is designed to stimulate our liver to release the glucose that is previously stored in the body system to the blood stream. Our body system, when it falls on under secretion or over secretion of certain hormones or other substances, it shift the normal body functioning negatively.
So therefore, the absence of glucagon receptor would lowers the blood glucose levels in the blood stream.

Which organisms have the type of survivorship curves that reflect the fact that most young survive, and survivorship is high until individuals reach old age?
small plants, like Cleome droserifolia
mammals, like Dall sheep
birds, like white-crowned sparrows
fish, like salmon
The correct option is mammals, like Dall sheep.
What is survivorship curves ?A survivorship curve refers to a graph showing the number or proportion of individuals surviving to each age for a given species or group. There are three types of survivorship curves as follow:
Type I curves depict individuals that have a high probability of surviving to adulthood. For example, large mammals have type 1 survivorship curves, because they have a. low infant mortality and high rates of survival into old age.
Type II curves also called as intermediate type, it depict individuals whose chance of survival is independent of age. For example, most birds have type 2 survivorship curves birds die more or less equally at each interval of their age.
Type III curves depict individuals that mostly die in the early stages of their life. For example, Trees, small mammals, some birds, oysters, shell fish, many insects, oak tree and fishes exhibit type 3 of survivorship curve because in these species mortality rate is high during the early stages of life.
Small plants, like Cleome droserifolia is a herbaceous perennials also typically display Type III survivorship curves, with a very low seedling survival and a low initial life expectancy,
Thus, from above explanation, mammals, like Dall sheep, is the correct option.

Need help with this question will global warming have catastrophic effects?
Global warming is predicted to produce an increase in extreme temperatures and it is caused mainly by an increase in CO2 levels. The increasing temperatures are likely to cause a modification in air circulation patterns and increase evaporation, among others. These have consequences over climate and produce an increment over frequency and magnitude of extreme climatological events (like hurricanes). Also, global warming leaves no place for adaptation (as it is fast compared to biological adaptation), so many species are likely to go extinct, with important ecological effects. I consider these to be catastrophic effects.

This passage describes the flower position trait in pea plants:Flowers can grow in different positions on a pea plant's stem. Axial flowers arein the middle of the plant's stem. Terminal flowers are at the tip of the stem.In a group of pea plants, some individuals have axial flowers and others have terminalflowers. In this group, the gene for the flower position trait has two alleles. The allele F is foraxial flowers, and the allele f is for terminal flowers.A certain pea plant from this group has axial flowers. This plant has one allele for axialflowers and one allele for terminal flowers.Based on this information, what is this pea plant's genotype for the flower position gene?axial flowersFfffterminal flowers
Axial flowers are in the middle of the plant's stem.
Terminal flowers are at the tip of the plant's stem.
The alleles that code for the trait "position of the flower" are F: axial flowers, and, f: terminal flowers.
A pea plant has axial flowers (Phenotype of the plant)
You know that it has one allele for axial flowers, F, and one allele for terminal flowers, f.

Some specifically selected hormones, cholesterol, LDL and iron enter cells via
A) exocytosis
B) endocytosis
C) pinocytosis
D) receptor-mediated endocytosis
Answer:
B) endocytosis
Explanation:
Endocytosis is the process through which things pass through the cell membrane and into the cell.
Endo = internal, within
Cystosis = referring to cells
Some specifically selected hormones, cholesterol, LDL and iron enter cells via Endpcytosis.
Thus, Some plasma-membrane proteins can be efficiently absorbed and concentrated through endocytosis linked to clathrin coating.
This method transports iron-loaded transferrin protein and cholesterol-containing LDL particles linked to these receptors into the cell, and it also internalizes the low-density lipoprotein (LDL) receptor.
By using electron microscopy, it is possible to see the characteristic basket-like structure that the clathrin coat that forms on these structures creates. It is thought that the polymerization of the clathrin coat promotes changes in membrane curvature, surface membrane deformation, and vesicle formation.
Thus, Some specifically selected hormones, cholesterol, LDL and iron enter cells via Endocytosis.
