Answer:

RBCs' production is controlled by erythropoietin.

Mature RBCs are released into the bloodstream after approximately seven days RBCs are produced in the bone marrow

Explanation:

The hormone erythropoietin is produced and released in the bloodstream by peritubular interstitial cells of kidneys. The function of erythropoietin is to increase the number of the precursors of red blood cells and thereby to stimulate the production of red blood cells in the bone marrow. When the oxygen supply to body cells is reduced, the hormone erythropoietin stimulates the development of proerythroblasts into reticulocytes and thereby increases the RBC production.

RBCs are produced by the process of erythropoiesis and take about seven days to become mature and to be released in circulation to serve the function of oxygen delivery. The maturation of RBCs also includes the loss of most of the organelles such as the nucleus and mitochondria to accommodate hemoglobin protein. The life span of circulating RBCs is about 100-120 days.

If a postsynaptic neuron is stimulated to threshold by spatial summation this implies that ________. If a postsynaptic neuron is
Maslowich

Answer:

The postsynaptic cell has many synapses with many presynaptic neurons

Explanation:

Spatial summation is a process of producing an action potential in a neuron with input from multiple presynaptic nerve cells. This process determines whether an action potential will be triggered upon reaching threshold from multiple synapses with presynaptic neurons. Summation of all inputs determines if an action potential will b generated.

What is the role of an indicator? Predict how the glucose test strips and iodine would react with the following foods:
mihalych1998 [28]
The main role of an indicator is to establish the equivalence point when two substance has reached its neutralization process. The purpose of an indicator is to determine how acidic or basic the product or solution is. Indicator solutions work by actually reacting with the components of food that they test for, creating a new substance of a different color. This is a chemical reaction.If the substance that they test for is not present in the food, there will be no reaction, and therefore no color change. The test strips will be more likely to be dark blue or black for Grape, Tomato, Summer squash, Orange Bell pepper as they all contain starch. Color intensity may vary depending on the level of starch found in the samples.

What is the percent by mass of 8.0g copper is added yo enough zinc to produce 100g an alloy brainly
kogti [31]

Answer:

8%

Explanation:

Given that,

Mass of solute = 8 g

Mass of soultion, (mass of alloy) = 100 g

We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :

\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%

So, the percent by mass is 8%.
