Answer:

<em>The statement that is incorrect is :</em>

<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>

Explanation:

A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.

Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.

In which type of human cell(s) would 46 chromosomes be located? Select all that apply.A. diploidB. eggC. somaticD. gameteE. sper
Marrrta [24]

Answer:

A. diploid and C. somatic

Explanation:

Humans are diploid organisms and have 23 pair of chromosomes i.e. in total humans have 46 chromosomes.

There are 2 types of cells in humans (1) somatic cells and (2) germ cells.

Somatic cells are normal body cells which are diploid and have all 23 pairs of chromosomes. But, germ cells are special type of cells which are produced by gonads (sex organs). Germ cells are also known as gametes. In females, ovary is the sex organ which produces germ cells named as egg cells while in males testes is the sex organ which produces germ cells named as sperms. Germ cells (egg and sperm) are haploid cells which fuse to form a zygote which is the first cell of next generation. The process of fusion of egg and sperm is known as fertilization which is responsible for restoring diploidy in the progeny which receives half the genetic material from female parent and half the genetic material from male parent.
