Answer:
<em>In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems</em>
In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.
When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.

The answer will be A because mitosis usually separate the sister chromatids to sister chromosomes to form two diploid cells. In meiosis, the goal is to have four haploid cells. To form that, cells need to undergo cell division two times. In the case of meiosis I, sister chromatids stay joined together until it reaches meiosis II. Then, the sister chromatids will separate starting at anaphase II in meiosis II. For example, if you start with 92 chromosomes (46 chromatids) during meiosis I, at meiosis II you will have two cells with 46 chromosomes (23 chromatids). By the end of meiosis II, you should form 4 haploid cells that contains 23 chromosomes.
The right answer is: <span>organelle, cell, and tissue
<span>Muscle is a soft tissue, found in animals. Composed of muscle tissue and connective tissue (+ blood vessels + nerves). The muscle cells (a component of the muscle tissue) contain actin and myosin protein filaments that slide on each other, producing a contraction that changes both the length and shape of the cell.
</span></span>The muscle cells, like other cells, consists of a plasma membrane containing a cytoplasm, which is formed of an aqueous solution (Cytosol) in which there are many biomolecules such as proteins and nucleic acids, organized or not in the context of organelles.<span>
