Answer:
B) slow- twitch, intermediate- twitch, fast-twitch
Explanation:
The three types of muscle fibers are:
- <u>Slow-twitch: </u>they are also called Red Fibers because of their color or type I. These type of fibers are resistant to fatigue, that means that they can contract for long periods, but its contraction is not very strong. Muscles that maintain our posture, such as our back muscles, have a predominancy of these types of fibers.
- <u>Fast-twitch fibers</u>: they are also called type II, or White Fibers because of their color due to the low supply of blood. They are fibers that contract very fast and are not resistant to fatigue. These types of fibers can generate higher amounts of force in a short period, but their contraction is for a short period. They are present in our eye's muscles.
- <u>Intermediate twitch fibers:</u> they characteristics are between the two types of fibers mentioned above. That is to say, that they do not contract as fast as fast-twitch fibers do but not as slow as slow fibers either, also, they fatigue quickly but nos as quicky as fast-twitch fibers or as slow as slow-twitch. They are in the majority of our muscles.
Producers, because they start the chain and the top most level finishes it.
The quality of water drawn from an aquifer differs in quality from surface freshwater because the surface water contains a lot of contaminant. Even when a ground water contains contaminants in it, it is filtered by the rocks in underground.
<u>Explanation:</u>
The water that are in river, ocean or any other water from surface level is known to be a surface water. This water is subjected to the exposure of many contaminants as they are directly on the earth's surface. These are known as "soft water" and they usually contain more minerals. The surface water can be contaminated by waste of humans, animals, industry wastes, etc. Hence they have low quality.
A Deep well drilling must be done in order to take water form the Large aquifers that are present Groundwater. The ground water also contains contaminant. But, the quality of these water is high since the rocks and soil found underground filters and removes the contaminates that are present in an underground water.
The correct answer is 'adrenarche'. This is also the period of early sexual maturation in humans and other higher primates. This period is associated with the development of pubic hair, body odor and acne. The adrenal cortex secretes higher levels of androgens. The development of a new zone of the adrenal cortex, called the zona reticularis, occurs during this period.
Answer:
Explanation:
Changes in Earth's system affects the growth of life on Earth. Since Earth has gone through so many stages and different stage has different growth of life. Life on Earth includes all the living things such as plants animals humans microbes etc. All take part in different cycles such as carbon cycle and nitrogen cycle and can influence global climate by changing chemical composition of atmosphere.
