Answer:
The observable traits expressed by an organism are referred to
EXPLANATION:
An organism's underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype. Mendel's hybridization experiments demonstrate the difference between phenotype and genotype.
Answer:
The BRCA gene is a tumor-suppressor gene found in the breast; to be more specific, it produces proteins that suppress cancerous activities/abnormal growth in the body. A mutation in a BRCA gene would allow these abnormal growth activities to go unchecked and thus increase the rate of mitosis. Cell cycle checkpoints would significantly be worse at their jobs of checking and correcting for errors during the cell cycle. Tumors would result as well, as cancerous growth continues, and the tumor can become metastatic.
Answer:
Secretion of the neurotransmitter serotonin, which is a water-soluble amine molecule
Explanation:
Exocytosis is defined as the process where cell transports secretary products which are packaged in transport vesicles such as antibodies, peptide hormones, secretory proteins, and enzymes with the help of cytoplasm to the plasma membrane.
Some example of exocytosis are:
1) Neurotransmitters secrets from nerve cells.
2) Antigens which helps to stimulate the immune response.
3) Proteins of the plasma membrane.
<h3><u>Answer</u>;</h3>
d. Na+
<h3><u>Explanation</u>;</h3>
- The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others.
- <em><u>Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.</u></em>
- Charged ions such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
