Mycoplasma mycoides is of particular interest because:
Mnenie [13.5K]

Answer: It has multiple nuclei, It is one of the smallest of cells with among the smallest of genomes.

Explanation:

Mycoplasma mycoides is a bacterial strain of the genus Mycoplasma. It belongs to the class of Mollicutes. This is parasitic in nature. It lives in the ruminants.  It is smallest known bacteria that does not posses the cell wall. It is present everywhere as a pathogen. It's function is to interfere with the ability of the virus to affect the mammalian cells. It posses multiple nuclei.

It is smallest free-living single celled organism. Due to the small size the entire genome can be sequenced. It can be useful for purpose of research and it is of particular interest because of it's small cell size and multiple nuclei. It serves as a model organism to study the bacterial evolution.

During which phase in erythrocyte development does the color of hemoglobin overcome the color of the stained ribosomes?
Sphinxa [80]

Answer:

The correct answer is - phase 2.

Explanation:

Erythropoiesis or the development of the erythrocytes is the process to which the development of the  erythrocyte cells from the bone marrow to the mature RBC. The development of these cells involved the three phases.

During second phase involves the differentiation of the precursors of the three different type of erythrocytes that are polychromatophilic, proerythroblasts, and orthochromatic erythroblasts. It also includes building up the color of the hemoglobin that overwhelms the color of ribosomes that is blue color.

Thus, the correct answer is - phase 2.

Oksana_A [137]

Answer:

a. Decrease water reabsorption : decrease blood pressure.

b. Decrease peripheral resistance : decrease blood pressure

c. Vasodilation : decrease blood pressure

d. Decrease salt intake : decrease blood pressure

e. Decrease blood volume : decrease blood pressure

f. Vasoconstriction : increase blood pressure

g. Increase peripheral resistance:  increase blood pressure

h. Increase salt intake:  increase blood pressure

i. Increase blood volume : increase blood pressure

j. Increase water reabsorption: increase blood pressure

Explanation:

  • Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow.  This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance.    
  • Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows.  This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others.    
  • Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure.
  • The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs.
  • Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.
