Revise this sentence by replacing all gerunds with infinitives.
vekshin1

Answer:

Please see below

Explanation:

I always tell people that I love to dance, to write and to paint.

The verb keep cannot take an infinitive afterwards so it is better to replace that expression  altogether with another one that means the same thing, but that can use an infinitive. The verb love can take either gerunds or infinitives afterwards with only a subtle variation in the meaning.

Which statement provides a possible explanation for the growth
Shtirlitz [24]

Answer:

<u>3) Uncontrolled cell division occurred as a result of gene mutations</u>

<u />

Explanation:

Spontaneous modifications within the genome may occur during the process of cell division. When copies of the DNA inside the cell are made, these mutations cause errors; and can include small single nucleotide polymorphisms, and large scale additions or deletions across multiple genes.

Some, like somatic mutations, exist only inside vegetative (body) cells, that cannot be passed onto offspring. This is caused by several factors like

  • UV radiation,
  • chemical mutagens,
  • infective agents

UV radiation damages strands of DNA, by causing dimers to form; here, consecutive nucleotide bases covalently bond instead of those on the complementary strand. This conformational change causes errors in DNA proofreading and repair mechanisms where bases are not well-incorporated into the strand- tumors (clumps of uncontrolled cell growth) may form, resulting in melanoma, a type of skin cancer.

Rama09 [41]

Answer:

B.

Explanation:

Biome is a combination of two words 'bio+ome,' which means life and its specified nature.

In simple terms, biome can be defined as a naturally occuring of a large number of flora and fauna that occupies major part of nature. Ecologists, who study biomes, defines it as a large community of flora and fauna that resides in the same ecology or environment. Biome not only consists of flora and fauna but also its abiotic factors such as the adaptation of animals in different environment.

Therefore, option B is correct.
