Answer:

The best explanation of how two (2) cell organelles work together to maintain homeostasis within a cell is: C) Chloroplasts (#2) convert solar energy to make simple sugars which are then used by the mitochondria (#5) to provide energy for the cell.

A cell refers to the fundamental (basic) functional, structural and smallest unit of life for all living organisms. Some examples of cell organelles found in all living organisms include;

  • Nucleus.
  • Mitochondria.
  • Lysosomes.
  • Chromosomes.
  • Ribosomes.
  • Endoplasmic reticulum.
  • Cytoskeleton.
  • Vesicles.
  • Golgi apparatus.
  • Cell membrane.
  • Chloroplasts.

Homeostasis can be defined as a biological process through which a living organism maintains a stable (steady) an internal, chemical and physical environment that is ideal to sustain life and enhance proper functionality.

In Plants, homeostasis takes place into two (2) distinct stages;

I. Chloroplasts convert solar energy to make simple sugars through photosynthesis.

II. These simple sugars are then used by mitochondria to provide the required amount of energy for the cell.

What is not contained in our blood?A. Blood Plasma
B. Leukoctyes
C. Erythrocytes
D. Lymph

Answers

i think it might be lymph, but its not one of the first two

Our blood contains blood plasma, leukocytes, and erythrocytes but does not contain lymph. Lymph is a separate body fluid, transported by the lymphatic system.

Blood consists of several components: blood plasma, leukocytes (white blood cells), and erythrocytes (red blood cells). Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It makes up about 55% of the body's total blood volume. Leukocytes are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. Erythrocytes, or red blood cells, are cells present in blood in order to transport oxygen. On the other hand, lymph, although a body fluid, is not a part of the blood. It is mainly composed of white blood cells and is transported by the lymphatic system, separate from the circulatory system that transports blood.

Describe what will occur the population if it increases in number when food is scarce?

Answers

Answer:

more people will die

Explanation:

If you have a big population and little food mor peple will die.
There will also be riots in the streets, criminals acts will increase, this could come from stealing to murdering for food, the animal kingdom will basically go near extinction if the government can’t control its people from hunting, ultimately governments might collapse under the demands of the people.

A dedicated surgery suite must be used for which type of surgery?

Answers

Major survival surgery on non-rodent mammals

Major survival surgery in non-rodent mammals must be conducted in dedicated facilities. Major survivalsurgery penetrates and exposes a body cavity, produces substantial impairment of physical or physiologicfunctions, orinvolves extensive tissue dissection ortransection (e.g., laparotomy, thoracotomy, jointreplacement, and limb amputation). The ultimate decision to classify a surgery as major or minor will bemade by the IACUC. Investigators cannot perform major survival surgery in non-rodent mammals in theirown laboratories, but must make use of IACUC approved survival surgery suites that meet federal standards.Major operative procedures on non-rodents will be conducted only in facilities intended forthat purposewhich shall be operated and maintained under aseptic conditions. Dedicated surgery suites must be1approved by the IACUC priorto use and inspected semi-annually. Contact the IACUC office for additionaldetails regarding dedicated surgical suites and major versus minor surgical classifications.

Match each type of cell junction with its description.Tight junctions
*prevent liquid from seeping between cells
Desmosomes
*act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions
*allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata
*openings through the cell walls of plant cells that allow adjacent cells to share materials

Answers

Answer:

Tight junctions - prevent liquid from seeping between cells

Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves

Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells

Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials

Explanation:

1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.

2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.

3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.

4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.

Final answer:

Tight junctions prevent liquid seepage between cells, desmosomes hold cells together, and gap junctions allow movement between animal cells.

Explanation:

  • Tight junctionsprevent liquid from seeping between cells by forming a barrier that tightly seals adjacent cells together, preventing substances from passing through the spaces between cells.
  • Desmosomes, on the other hand, act as rivets to hold adjacent cells together when epithelial tissue moves or is subjected to mechanical stress.
  • Gap junctions, found in animal cells, allow the movement of cytosol, ions, and small molecules between cells, enabling communication and coordination.
  • Plasmodesmata, found in plant cells, are openings through the cell walls that link adjacent cells and allow them to share materials, such as water, nutrients, and signaling molecules.

what is the autonomic nervous system about? explain full details, like a reflection on it. I will give brainliest if answered correctly

Answers

the autonomic nervous system is responsible for regulating the activity of glands, smooth muscle, and cardiac muscle. its under involuntary control, meaning it works without us telling it to do so. it's divided into two divisions: sympathetic and parasympathetic. in sympathetic division, here, the preganglionic fiber is short and the preganglionic fiber is long. sympathetic division is very important during emergancy situationd and is commonly associated with "fight or flight" response. it accelerates the heartbeat, dilates the bronchi, and inhibits the digestive tract. the parasympathetic includes cranial nerves and fibers. it is often referred to as the "rest and digest division". here, the preganglionic fiber is long and the preganglionic fiber is short. it promotes responses associated with a relaxed state, such as pupil contraction, digestion of food, and a reduced heart rate.

Benedict’s solution is an alkaline copper sulfate solution which is used to detect the presence of aldehyde groups. In the presence of Benedict’s solution, the aldehyde group is oxidized and the aqueous blue Cu2+ ion is reduced to a red Cu2O precipitate. Sugars such as glucose, which produce the red precipitate when Benedict’s solution is added, are called reducing sugars because they can reduce Cu2+ to Cu+. Which of the following carbohydrates would give a positive reaction with Benedict’s reagent? a. galactose; b. sorbitol (see below); c. β-ethylglucoside; d. gluconate .
As recently as 1996, the black-footed ferret, North America's only native ferret species, was listed as "extinct in the wild", with only captive individuals surviving in zoos and captive rearing programs. In 2002, 223 ferrets were released in Wyoming in an attempt to re-establish a wild population. Of these only 68 individuals survived the winter into 2003. By 2010, conservation biologists counted 760 ferrets, with an estimated annual growth rate of 0.35, one of the highest of any endangered species managed under the Endangered Species Act. The status of black-footed ferrets will be reevaluated and potentially downgraded from "critically endangered" to "endangered" once their population size exceeds 2000 individuals. Assuming no change to their annual growth rate in 2010, in what calendar year (in AD) would this occur?
HIV's genome of RNA includes the code for reverse transcriptase (RT), an enzyme that acts early in infection to synthesize a DNA genome off of an RNA template. The HIV genome also codes for protease (PR), an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. Both RT and PR represent potential targets for antiretroviral drugs. Drugs called nucleoside analogs (NA) act against RT, whereas drugs called protease inhibitors (PI) act against PR. Which of the following treatment options would most likely avoid the evolution of drug-resistant HIV (assuming no drug interactions or side effects)?(a) Use a series of NAs, one at a time, and change about once a week.(b) Use a single PI, but slowly increase the dosage over the course of a week.(c) Use high doses of NA and a PI at the same time for a period not to exceed one day.(d) Use moderate doses of NA and two different PIs at the same time for several months.
