regulate blood flow into the capillary bed and respond to local chemical conditions. If the tissue is metabolically active, they

would _________________________ in diameter to allow flow into the tissue. If the tissue is not metabolically active, they would _________________________ in diameter and blood would be __________________________ through the capillary bed.

Pre-capillary sphincters regulate the blood flow into the capillary bed and respond to local chemical conditions. If tissue is metabolically active it would increase in diameter to allow flow into the tissue. If the tissue is not metabolically active it would decrease in diameter and blood flow would be decreased through the capillary bed.

<h3>What are Pre-capillary sphincters?</h3>

A precapillary sphincter is a band of pericytes or smooth muscle-like contractile mural cells that regulates blood flow into capillaries. They were once believed to solely exist in the mesenteric microcirculation, where they had been first described.

Changes take place while the metabolism is active.

  • A rise in the level of adenosine
  • A spike in the area's carbon dioxide levels.
  • An increase in blood lactate levels.
  • A high pH. A drop in oxygen concentration

The tissue's metabolism slows down after it has been removed.

Since the temperature drops frequently, the reported variations must take these potential variables into account.

If the tissue is maintained via temperature and perfusion systems, it may be stabilized in a living state in vitro.

<u>Pre capillary sphincters </u>regulates the blood flow into the capillary bed and respond to local chemical conditions. If tissue is metabolically active they would <u>increase </u>in diameter to allow flow into the tissue. If the tissue is not metabolically active they would <u>decrease</u> in diameter and blood flow would be<u> decreased </u>through the capillary bed.

When the metabolism is operating, changes are created.

1. An increase in adenosine concentration

2. a rise in carbon dioxide levels there.

3. A rise in lactic acid levels.

4. A high pH.

5. A decrease in oxygen content

  • After the tissue has been removed, the metabolism of the tissue slows down.
  • The recorded variances must take these potential variables into consideration because the temperature drops often.
  • The tissue may be stabilized in a live condition in vitro if it is sustained by temperature and perfusion systems.

One day you notice that part of your garden is much more prolific in producing flowers than another part. You observe that some
makvit [3.9K]

Answer and Explanation:

The steps of the scientific method are

1) A question the investigator wants to answer.

2) Antecedents or Previous knowledge about the study object.

3) The goal, which is what the investigator wants to know.

4) The hypothesis that the investigator makes in order to predict what is going to happen.

5)The experiment is performed to answer the question.

6) Results achievement

7) Conclusions where the hypothesis is rejected or accepted.

In the case of the exposed example,

  1. Question: How does the amount of sunlight affect the extent of flower production?
  2. Previous knowledge and antecedents about solar radiation influencing different plant growth and flowering. Information about the species of interest. Other studies or investigations performed in relation to this question.
  3. Objective/Goal: To study the influence of sunlight in flowering
  4. Hypothesis: Too many hours of radiation affect flowering production
  5. Experiment: (Example)

Native species are going to be planted in the garden to observe their growth and flower production at different exposure levels to sunlight. Native species will be planted, as they are used to the environmental conditions and they do not need extra care, as a cultivated species would. More than one individual is needed to ensure their establishment. All the species will be watered according to each species needs and location. Plagues will be equally controlled.

  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives straight sun radiation during the whole light hours.  
  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives sun radiation during half a day
  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a  shaded section.

Plants will be grown and the flowering process will be recorded by season in relation to the number of flowers, sizes, quality, and pollinizer visitors which will reflect the amount and quality of nectar.

6 y 7. Every recorded result will be then analyzed to conclude.
