The thymus gland is the main organ of the lymphatic system. Located in the upper chest region, the primary function of this gland<span> is to promote the development of specific cells of the immune system called T lymphocytes.</span>
The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the offspring's genes. This means that the offspring is a unique composition of the two parents.
In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.

<h3><u>Answer;</u></h3>
The law of independent assortment
<h3><u>Explanation;</u></h3>
- The Principle of Independent Assortment illustrates how different genes individually separate from one another when reproductive cells receive.
- Independent assortment of genes and their similar traits was first mentioned by Gregor Mendel in 1865 during his studies of genetics in pea plants.
- When two or more characters are acquired, individual hereditary factors classify independently during gamete production, giving distinct traits an equal opportunity of befalling together.
Explanation:
What I got to have
Eutrophication (from Greek eutrophos, "well-nourished") is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients. It has also been defined as a "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication in freshwater ecosystems is almost always caused by excess phosphorus.
