How is a delta formed

Answers

Answer 1
Answer: When a river reaches a lake or the sea the water slows down and loses the power to carry sediment . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layersforming a delta.

Derek takes protein supplements before and after his workouts. He told his workout partner that he became 200% stronger within a couple of months after he added the supplements to his diet. His report about the effects of the supplements is an example of a(an) ________.

Answers

Answer:

anecdote

Explanation:

This report would contain his journey of change in his physiology during the stint of two months during which he took protein supplements before and after his workouts.The report will reveal how he become 200% stronger after he added the supplements to his diet. Therefore, the would be an anecdote of this amazing journey of transformation.

While dna in a human cell was being replicated, a single base was miscopied. what will most likely be the result for the cell in which it happened?

Answers

Answer:

The options to this question are missing, they are:

A) All the proteins the cell creates from the miscopied strand will do different jobs than the old ones.

B) Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides.

C) Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded.

D) If the new sequence codes for the same amino acid as the original cell, it will function normally.

THE CORRECT ANSWER IS D

Explanation:

What occured to this cell replicating its DNA is called MUTATION, which is a change (small or big) in the nucleotide sequence of a DNA. The miscopied base will alter the nucleotide sequence of the DNA. Since a single base is involved, it is referred to as a POINT MUTATION.

A point mutation, such as the one in this case, can produce varying effects in the resulting organism. The mutation can either lead to a different protein in that particular sequence the mutation occured or have no effect on the organism.

The mutation will have no effect on the organism in a case where the base that was miscopied produced a codon that codes for the same amino acid as the original codon. Hence, the same protein will be produced and have both effect on the cell. This is possible because of the degenerate nature of the genetic code, as more than one codon codes for a given amino acid.

Mutation I presume ??

b
a biome.
c
an ecosystem.
d
a species.

Answers

Answer:

c

Explanation:

Answer:

a biome

Explanation:

a species is a type of animal kind, a population is the number of a certain species, an ecosystem is basically a big web of nature that is connected. so we can rule those 3 out. a biome is a part of land with similar climates and organism population
