Answer:
The correct answer is C. A buildup of lactic acid in the tissues.
Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.
Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.
Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.
This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.
In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
<span>Membrane structure and function: The plasma membrane, also known as the cell surface membrane or plasma-lemma, is the boundary of the cell. It regulates the movement of materials into and out of the cell and facilitates electrical signaling.</span>
Answer:
water is constantly moving across the earth. The water is strong enough to break down soil in tiny pieces. What’s happening is a process called erosion. Erosion is: the process of eroding or being eroded by wind, water, or other natural agents.
"the problem of soil erosion".
Water also carries sand and moves it around, this obviously changes the shape of the earths surface!
Explanation:
Answer:
It gives useful information about environments and the ways past organisms lived
Explanation:
A fossil is basically any preserved remains or trace of any organism that once lived in the past. Bones, shells and exoskeletons are examples of fossils that can be studied through Paleontology.
From fossil studies, we can tell how long these lives existed on earth and how varying plants and animals are related to one another. We can often find out how and the places they lived and their environments as well.
