Nutrients in the deep ocean come from dead marine organisms. <br>True<br>False​
Viktor [21]

Answer:

True

Explanation:

The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.

State the meaning of the red blood cell count, percentage of reticulocytes, hemoglobin, hematocrit, mean corpuscular volume, and
saveliy_v [14]

Answer: Red blood cell count is a diagnostic blood test used to determine the amount of red blood cells an individual has.

Percentage of reticulocytes refers to the amount of immature red blood cells one has.

Hemoglobin is the protein component of red blood cells responsible for carrying oxygen.

Hematocrit is the proportion of red blood cells in the total volume of blood.

Mean corpuscular volume refers to the mean volume of red cells within an organism.

Mean corpuscular hemoglobin concentration refers the intracellular hemoglobin count.

Explanation: Anemia is a condition that is characterized by a reduced total hemoglobin count or number of red blood cells. Anemia can be classified according to various factors that include pathophysiology, that is the factors surrounding the onset of the condition or by cell size, which  refers to mean corpuscular volume (MCV) or by the amount hemoglobin, which is referred to as the mean corpuscular hemoglobin (MCH). The diagnosis of anemia is dependent on red blood cell counts which encompass reticulocyte, platelets and leukocyte counts. Critical blood counts that look at MCV and MCH are a disgnostic feature for the various types of the condition. A high reticulocytes percentage is often associated with anemia.

Alex73 [517]
<h2>Sodium channels </h2>

Explanation:

Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli    

  • Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
  • Action potential is an efficient signaling process by which distantly located cells communicate to each other
  • Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
  • Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
