charle [14.2K]3 years ago
7 0

Answer:

Cell membrane:  provides protection for a cell

cytoplasm : acts as a buffer and protects the genetic material of the cell

nuclear membrane : serves to separate the chromosomes from the rest of the cell

nucleus : The nucleus controls and regulates the activities of the cell

chromatin : They act as packaging elements for the DNA

nucleolus : function is RNA synthesis and ribosome biogenesis

Ribosome : decoding the message and the formation of peptide bonds

vacuole : vacuoles help maintain water balance

lysosome : They break down excess or worn-out cell parts

Smooth endoplasmic reticulum :  Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins

Rough endoplasmic reticulum : its function is to produce proteins for the rest of the cell to function

mitochondria : generate most of the chemical energy needed to power the cell's biochemical reactions

golgi body/ apparatus : organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell

You observe that your friend has dimples. dimples result from the presence of the dominant gene d; absence of dimples is a homoz
anzhelika [568]

Answer:

DD or Dd

Explanation:

Dimples is the dominant trait (D). Your friend has dimples so that means he or she should have at least one allele of the dominant trait to express that trait. So your friend would either be homozygous dominant (DD) or heterozygous dominant (Dd). Notice that there is a recessive allele in the second. Even with that present, dimples would be still expressed.

In a flowering plants species, red flower color is dominant over white flower color. What is the genotype of any white-flowering
katovenus [111]

Explanation:

<u>C. A red allele is present on both homologous chromosomes</u>

<u></u>

Homologous chromosomes are pairs of chromosome of similar lengths, banding patterns, and centromere positions, with genes at the same loci. For dominance, gene copies are present on both of the chromosomes; the dominat variant overrides the effect of the other recessive allele.

Further Explanation:

DNA molecules contain chromosomes that may have different forms called alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new alleles, impacting the associated mRNA, and thus the encoded protein.

Homozygous individuals have a chromosome containing two variants of the same allele. Dominant homozygous individuals bear two copies of the dominant allele, whereas recessive homozygous individuals hold two copies of the recessive allele.
