True. The embryonic period is the second period of prenatal development and extends from the third week through the eighth week.
<h3>
What is embryonic period?</h3>
Your kid goes through a phase of rapid change after conception known as the embryonic stage. From the fifth through the tenth week of pregnancy, this phase lasts. The infant is referred to as an embryo at this point. The embryonic stage is when a lot of changes take place.
<h3>What happens during embryonic stage?</h3>
The heart starts to beat and the organs develop and start to work during the embryonic period.
<h3>Why is embryonic stage important?</h3>
The brain develops during the embryonic period, which is crucial.

<span>The population dynamics of the Warbler species differ from what's documented by Scott Sillett and colleagues one migration issues.
The Warbler species are non migratory species, while Scott Sillet and colleagues have been studying migratory species. The Warbler species were even taken to other islands, in some cases, in order to give them the </span>security of additional breeding populations, this because their population dynamics is not a migratory one. The studied species by Scott Sillet and colleagues, on the other hand, have migratory population dynamics: they pass their Summer time in <span>New Hampshire and and their Winter time in Jamaica.</span>

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.
