Mutations are changes that occur in DNI nucleotide sequences that introduce new variants.
There are different types of mutations. In the exposed example, the last thymine from the Wild-type beta-globin gene fragment is replaced by an adenine in the Sickle-cell beta-globin gene fragment. The other bases remain equal.

Why are braided streams common in sedimentary rocks before the arrival of plants on land ?
Answer:
Braided rivers have a multithreaded plan form comprising many confluences and diffluences (Miall, 1977). Braid bars and channels can be classified as a hierarchy depending upon their relative size, and three orders of braiding can be seen in proglacial rivers with constant discharge. First-order braid bars are those largest bars which are separated by major channels. First-order bars are made up of a series of smaller, second-order braid bars, which are separated by smaller channels. Third-order braid bars are contained within second-order bars. Complexity of braid pattern is, however, strongly stage dependent, with rivers losing their braided character during peak flood conditions. Braid bars, mid-channel bars, unit bars, and islands have been described in braided river systems on a range of scales ranging from meters to kilometers. All bars are subject to dissection , remobilization, and migration by the appropriate discharge magnitude and frequency (Miall, 1977, 1983).

why could the formation of a hole in the ozone layer cause concern?
Answer:
Because it can damage the protective layer in the earth's atmosphere, therefor causing a risk of high damage from meteorites and asteroids.
Explanation:
The formation of a hole in the ozone layer would cause concern because it increases the amount of ultraviolet rays that reach Earth and can harm it's inhabitants.

which describes the Grand canyon as it will be one million years from today?
Answer:
I think it will become shallower and narrower.
Explanation:
This is because today, the Grand Canyon is deep and wide, we are talking about how it was one million years ago, which would look noting like this today. Little piece of rock has started to fall off of the sides of the Grand Canyon so it looks how it looks today.

Which structure is most directly responsible for maintain homeostasis in all the cells?
Answer:
Cell membrane or plasma membrane is most directly responsible for maintain homeostatis in all cells.
using example, explain the concept of homeostasis
Answer:
Homeostatis: maintenance of constant internal environment (optimum temperature or optimum optimum osmotic concentration) that permits all the biochemical reactions and physiological functions to proceed with maximum efficiency.
▪For example, when we exercise, there is heat production in the body and the body temperature rises which gets detected by the nerve sensors present in the body and the temperature control system in the brain is activated. It then activates sweat glands that helps in bringing the body temperature back to normal.

In gymnastics, a gymnast must be able to balance on a balance beam. What is the best explanation for what forces are acting on the gymnast on a balance beam? (2 points)
The forces are balanced when the force of gravity pulling you down is the same as the force of the balance beam pushing you up.
The forces are unbalanced when the force of gravity pulling you down is the same as the force of your legs pushing you up.
The forces are balanced when the force of gravity pulling you down is stronger than the force of the balance beam pushing you up.
The forces are unbalanced when the force of gravity is reduced to the same force as the balance beam pushing you up.
Answer:1
Explanation:Because gravity always pulls you down even when your standing on an object.

Name three reasons, as to why, bacteria is so widespread into different life/ecosystems
Answer:
Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria.The most influential bacteria for life on Earth are found in the soil, sediments and seas. Well known functions of these are to provide nutrients like nitrogen and phosphorus to plants as well as producing growth hormones. By decomposing dead organic matter, they contribute to soil structure and the cycles of nature. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Explanation:
