Answer:

pacemaker cells.

Explanation:

Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells.

In response to seasonal changes in temperature, many organisms must alter the composition of their plasma membranes to maintain
katrin [286]

Answer:

The correct answer is D

Explanation:

The cell membrane is essentially composed of the following:

  • phospholipids
  • cholesterol
  • proteins

The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.

There are 3 main factors that greatly influence the fluidity of the plasma membrane:

  • temperature
  • cholesterol
  • saturated and unsaturated fatty acids

Mitosis is a process used for normal growth and development. Explain how and why a mutation in a BRCA gene may affect the cell c
Romashka [77]

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.

<h2>Production of mitochondrion DNA  </h2>

Explanation:

  • The cell is not capable to complete reaction related to ATP production and electron transport.
  • This is because the electron transport chain and ATP production are combined with the association of protein in the inner membrane of mitochondrion DNA.
  • Mitochondria are the powerhouses of the cell. In all eukaryotes that don't rely upon photosynthesis, the mitochondria are the primary wellspring of adenosine triphosphate (ATP), the vitality rich intensify that drives central cell capacities.
  • These capacities incorporate power age (for instance, in muscle compression and cell division), the biosynthesis, collapsing and debasement of proteins, and the generation and control of membrane possibilities.
