r) declines to 25% of normal
Biology

MaRussiya [10]2 years ago

A adequate amount of parathyroid hormone can no longer be secreted by the parathyroid gland .

  • GFR declines when the macula densa notices an increase in the concentration of NaCl in the renal filtrate.
  • By monitoring filtrate osmolarity, the macula densa controls the body's blood pressure. If it falls too low, it causes the kidney's afferent arterioles to constrict, increasing pressure at the glomerulus and increasing glomerular filtration rate.
  • Increased sodium chloride supply to the macula densa causes the production of adenosine, which causes vasoconstriction when it binds to the afferent arteriole. GFR is reduced as a result of the vasoconstriction.

It is thought that the distal tubule fluid's sodium content and maybe the speed at which the fluid passes through them cause the macula to react.

During inspiration, the intrapulmonary pressure is the atmospheric pressure. At this point the intrapulmonary pressure is ______
Feliz [49]

During inspiration , the intrapulmonary pressure is the atmospheric pressure. At this point the intrapulmonary pressure is  greater that intrapleural pressure.

Air flows into the lungs largely due to difference in pressure , atmospheric pressure is greater than infra-alveolar pressure . It is changes during the different phases of breathing because the alveolar which connected to atmosphere via tubing of airways.Due to certain characteristics of the lungs the intrapleural pressure is always lower than or negative to the intra-alveolar pressure.

Intrapleural pressure  air within the pleura cavity , Intra- alveolar pressure, between the visceral and parietal pleurae, , intrapleural pressure which is also changes during the different phases of breathing and due to certain characteristics of the lungs, the intra-alveolar pressure .

Why is it helpful to conduct a large number of trials when simulating genetic crosses?
Rainbow [258]
<span>Answer: If you were expecting a ratio of 9:3:3:1 you would have to make sure that you had enough offsrpring to count to give yourself a chance of getting that ratio. If you only had 8 offspring you would never get the ratio. Remember genetic ratios are probabilities of what to expect and you need a large enough sample to ensure accuracy.</span>

Sindrei [870]

Answer:

The correct answer is option E.

Explanation:

The effect on the growth of the full sunlight and green light or the increased carbon dioxide and normal air. There are several effects that can affect the growth of the plant can be affected. Provided options are directly or indirectly affects the variables that are unknown but can affect the growth of plants.

Increased in carbon dioxide does not leads to the decrease of other essential gasses in substantial amount, common uniform strain of seedlings are also cause effects the experiment of plant growth in specific manner. Light is also one of influential and limitation factor that affects the growth of the plant.

Thus, the correct answer is is option E.
