Which is the functional unit of the kidney where blood is filtered, water and other dissolved substances are reabsorbed, and waste is sent out to be excreted?

Answers

Answer 1
Answer: The correct answer to this question would be the nephron. The nephron is the functional unit of the kidney. It is where the blood, water, wastes that are in the form of fluid, and other dissolved substance (small enough to pass through the kidney) is sent out and to be excreted.
Answer 2
Answer:

D. Nephron

Hope it helps :)

How does biofuel use differ from solar, wind, and geothermal energy use? a. Biofuels can have a more widespread use. b. Biofuels are less damaging to the environment. c. Biofuels are not a renewable energy source. d. Biofuels cannot be used as an energy source. a. Biofuels can have a more widespread use. b. Biofuels are less damaging to the environment. c. Biofuels are not a renewable energy source. d. Biofuels cannot be used as an energy source.

Answers

The correct answer is option (a) Biofuels can have a more widespread use.

Biofuel is a fuel that is produced from biological process like anaerobic and agriculture digestion. It can be derived directly from plants, agricultural, commercial, domestic and agricultural waste. It has a more widespread use as compared to solar, wind and geothermal energy. Uses of biofuel.

  • It can be used as an alternative diesel
  • It can be used for power generation in backup systems when emission is most important
  • Bioheat can be generated from biofuel
  • It can be used to clean oil spills and grease
  • It can be used as a lubricant
  • It can be used as a fuel in stove for cooking
  • It can be used to remove paint and adhesives
a. Biofuels can have a more widespread use.
i think the answer is "a".

Diuretics are often prescribed to treat high blood pressure. Given the name of the class of drug, how do diuretics affect the kidney, the fluid and electrolyte balance in the body, and the overall blood pressure?

Answers

Diuretics incease the urine flow within the excretory system. 

The kidney which is responsible for the process of filtering toxins and other harmful chemicals within the cells produce urine as a form of product which is the combination of all the harmful chemicals. 

During meiosis, homologous sets of four chromatids are lined up along the cell's equator, attached to spindle fibers. Which of the following processes will happen next?A) Anaphase 1
B) Telophase 2
C) Prophase 1
D) Metaphase 2

Answers

Answer:

A) Anaphase 1

Explanation:

In sexual reproduction, Meiosis is a nuclear division of diploid cells that results into haploid cell. In Meiosis 1, the stages involved in the process include;

Prophase I

Prometaphase I

Metaphase I

Anaphase I

Telophase I  

In prophase I, the chromosomes condense and it visibility is vivid inside the nucleus. When nuclear envelope starts to break down, homologous chromosomes move closer together.

The important role in prometaphase I is the formation of the spindle fiber in which the spindle fiber microtubules attach to the kinetochore proteins at the centromeres.

During metaphase I, homologous sets of four chromatids  (tetrads) move and orient themselves  to the metaphase plate with kinetochores facing opposite poles. Followed by a kind of random orientation of  homologous pairs at the equator.

This stage is followed by Anaphase I where  microtubules slightly pull the chromosomes that are attached together apart. Though, the sister chromatids remain tightly bound together at the centromere. Also, the chiasmata are broken in anaphase I , as well as the microtubules attached to the fused kinetochores pull the homologous chromosomes apart.

This process of meiosis I ends in  telophase I, where the separated chromosomes arrive at opposite poles.

From the concept of meiosis I explanation, we can arrive at a conclusion that Anaphase I follows the process where  homologous sets of four chromatids are lined up along the cell's equator, attached to spindle fibers.
A) anaphase. It's when the pairs of chromosomes are pulled apart by spindle fibers.

Which method would allow you to study the behavior of a tiger in its native habitat in India?

Answers

The answer is field investigation.

A field investigation includes observation of free-living animals in their natural habitat without affecting them, their behavior, or their habitat. So, observation of tigers' activity in their native habitat is an example of the field investigation. The investigator would simply observe their behavior, not affecting the tigers in any way.
