differentiate between Acute and chronic diseases ...(minimum 5 points each)......pls help fast ....i have my exam tomorrow

Answers

Answer 1
Answer: Acute diseases are sudden, severe, and short term only. They quickly appear and worsen without warning and they disappear. Examples of this are flu or colds.  

Chronic diseases, on the other hand, are long-developing diseases. The symptoms have been present for long time and it worsens as time progresses. Examples of this are Osteoporosis and heart disease.

I think it is A. Molting

The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection?a. Directional selection
b. Stabilizing selection
c. Disruptive selection

Answers

b. Stabilizing selection. In stabilizing selection, the average trait in the population is more favored. In this case, the average leg muscle is favored over heavier and lighter because it can benefit Siberian Husky's role more.

The answer is the second option B

Precipitation includes ______.

hail
rain
snow
all of the above

Answers

Anything that falls from clouds is considered precipitation so the answer is all of the above.

Final answer:

Precipitation includes all forms of atmospheric water vapor that falls under gravity, including hail, rain, and snow.

Explanation:

In meteorology, precipitation refers to any product of the condensation of atmospheric water vapor that falls under gravity. This includes forms such as rain, snow, and hail. So, the answer to your question - Precipitation includes hail, rain, snow, or all of the above - is indeed, all of the above.

Which plant cell organelle helps maintain the shape of the cell by helping to maintain turgor pressure? A) cell membrane B) cell wall C) vacuole D) cytoskeleton

Answers

Answer: The correct answer is- C) vacuole.

Large central Vacuole is a specialized fluid filled organelle, present only in plant cell. It is primarily involved in providing support and shape to the plant cell by maintaining the turgor pressure ( a hydrostatic force that is produced due to the cell contents against the inner side of the cell wall). The central vacuole stores water ( that flows through osmosis) and maintains turgor pressure in a plant cell.

Turgor pressure provides mechanical support and helps in the growth and development of plant.

The plant cell organelle which helps in maintaining the shape of the cell by maintaining turgor pressure is vacuole.

Further Explanation:

The vacuole is an organelle which is mainly present in animal and plant also. There is a difference in size of plant and animal vacuole. Plant cells contain vacuole in the centre of the cell which is much larger than the animal vacuole. Animal cells contain multiple vacuoles that are scattered in the cytoplasm of the cell. They contain membrane-bound sacs. The cell membranes of vacuoles are made up of phospholipids. Proteins are embedded in the cell membrane to transport small molecule. Most plant cells use vacuoles to store water. Animals don’t use vacuole as water storage they store product for endocytosis and exocytosis.

The major functions of vacuoles are:

  • To store water in plants
  • To provide turgor pressure
  • To store material of exocytosis and endocytosis
  • To store fat cells

Manly in plants, a large vacuole is present. This vacuole is enclosed by a cytoplasmic membrane which is tonoplast. This layer can easily stretch and fill with solution. They can easily fill with proton and create acidic environment inside the cell. The development of chemical gradient is helps in transporting material inside and outside of vacuole. They use proton motive force to transport molecule. The vacuole when filled completely with water exerts a pressure on walls of cells called turgor pressure. These force help in maintaining the shape of the cell. Also, allow cells to stand up in rain, wind and hail.

The diagram represents the ____________ formula of glucose.A)
empirical
B)
ionic
C)
molecular
D)
structural

Answers

The answer is D) Structural

That is because we can automatically cross A out, and B is not the answer because ionic compounds aren't polyatomic. Poly atomic atoms are covalent and have no charge. While on the other hand, ions have a charge.
Also, C is not the answer because the molecular formula for glucose is C6H12O6, that leaves us with choice D.

I can pretty much conclude that D is the answer because you can see that the picture, it has a structure for the compound. Its showing us how the atoms are bonded and structured. 

Answer:

answer is d) structural

Explanation:

In what structures do the enzymes actually chemically digest food?

Answers

It's the amalyse that digested the food or starch in out mouth. Amalyse is an enzyme that is responsible to break down the starch in to sugar. Usually, it is present in our saliva, this is where the digestion started then next to our stomach.
