Identify and analyze the way fossil fuel combustion has changed the composition of Earth's atmosphere, and the way this change has affected climate.
Answer:
Increases the concentration of carbondioxide gas in the atmosphere.
Explanation:
The burning of fossil fuel increases the concentration of carbondioxide gas in the atmosphere because when the fossil fuel burns, carbondioxide gas is released. Carbondioxide gas is a greenhouse gas which goes up in the atmosphere and make a layer which allow light radiation to the earth but prevent it from going to the space after reflection which causes increase of surface temperature of the earth leads to global warming.
The fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.
What is concentration of carbon?
Concentration of carbon means the amount of carbon in the atmosphere.
The amount of carbon dioxide has increased substantially after the industrial era.
The concentration of carbon is 400 parts per million in more traffic areas.
The level of indoor carbon depends upon the number of person present there.
Thus, the fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.

Which gene mutation would have the smallest impact on a protein's amino acid sequence?
Answer:
Point mutation
Explanation:
Point mutation is a kind of mutation that involves a single nucleotide base. Generally, mutation is any alteration that occurs to the genetic sequence of an organism, however, point mutation involves only one base of the numerous in the sequence.
Point mutation can be an insertion, substitution, deletion etc, but it is the gene mutation that would have the smallest impact on a protein's amino acid sequence. This is because the change to the genetic sequence involves a single base.
What is the effect of an increased concentration of calcium ion in the sarcoplasm?
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The effect that can be associated with increase in concentration of calcium ion in the sarcoplasm is :
Changing of shape and position of tropomyosin.
Can also cause muscles stiffness.
When the Ca2+ concentration become high in the sarcoplasm, there would be change in the position of tropomyosin as result of the binding effect of Ca2+ binds on troponin.Then the tropomyosin will be moved away from myosin binding sites on actin, then a cross bridge will be formedHowever, the effect if this on muscles is muscles stiffness.

Answer:
d
Explanation:
bc its d
The characteristic that makes marine mammals different from other marine animals is that they breathe air through their lungs. Thus, the correct option for this question is D.
What are the characteristics of marine mammals?The characteristics of marine mammals may significantly include they breathe air through the lungs, being warm-blooded, having hair (at some point during life), and producing milk to nurse their young — while also living most or all of their lives in or very near the ocean.
Marine mammals have the same characteristics as all other mammals, but they have adapted to living all or part of their life in the ocean. Many have streamlined bodies to help them swim faster. With similar to the Fishes and other animals that have gills so they can breathe underwater. Marine mammals do not have gills. They have to come to the surface to breathe.
Therefore, the characteristic that makes marine mammals different from other marine animals is that they breathe air through their lungs. Thus, the correct option for this question is D.

Which is the best explaination for how chemical energy is transferred with cells
Answer:
Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.

A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ *
1 point
a. produce far more ATP than is necessary in response to the lack of oxygen
b. continue to go through aerobic respiration if enough sugar is present
c. die since all living organisms need oxygen to survive.
d. perform anaerobic respiration in the absence of oxygen
Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.

What is the Law of Universal Gravitation and how did it differ from the understanding of the motion before Newton theorized it?
How do you think Newton’s discoveries help to pave the way for his Three Laws of
Motion?
Answer:
While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Brahe had collected a lifetime of astronomical observations, which, on his death, passed into Kepler’s hands. (Brahe, who had his own Earth-centered model of the Universe, withheld the bulk of his observations from Kepler at least in part because he did not want Kepler to use them to prove Copernican theory correct.) Using these observations, Kepler found that the orbits of the planets followed three laws.

Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
