Answer: Hydrochloric acid is responsible for the acidic medium of the stomach, it creates an optimum acidity in the stomach. HCl makes digestion easy in the stomach.

How digestion of food takes place in our digestion system?

  • The process of the breakdown of the food into simpler and soluble particles is called digestion.
  • Teeth convert the food into pieces so that they can digest easily.
  • In the mouth, saliva converts starch into soluble sugar.
  • After the mouth, the bolus of the food goes into the stomach, where the food is partially digested.
  • Partially digested food is completely digested in the small intestine.
  • Undigested food passes into the large intestine, from where the waste product is excreted out through the rectum and anus.

Explanation: The stomach wall releases hydrochloric acid, which makes the medium of the stomach acidic to kill the germ that enters the stomach and activates the pepsin enzyme.

How did the Earth get these different layers? Did the Earth always have very separate, distinct layers? Describe what happened.
Orlov [11]
Answer: The different layers are a result of lighter parts (such as the continental crust) settling at the surface level and heavier parts (such as iron and nickel in the core) settling in the middle. The layers separate by density, otherwise known as compositional layering. The earth did not always have these layers, as it had to undergo cooling to form some of them (like the continental crust).

3. Suppose you are viewing a sample from a PURE culture and observe both red and purple cocci. What are the possible problems th
Scorpion4ik [409]

Answer:

The culture might not be stained properly or the culture might be too old.

Explanation:

Gram staining is done to differentiate between gram-positive and gram-negative bacteria according to the difference in their cell wall. In gram staining, the gram-positive bacteria appears violet and gram-negative bacteria appear pink in color.

Therefore if a pure culture contains have both red and purple cocci that it can be concluded that the gram stating was not done properly like too much destaining was done or too much safranin was used or maybe the culture is too old so that cell wall of some bacteria degrades.

castortr0y [4]

Question:

Which of the following is an incorrect statement about the regulation of populations?

Answer:

b. Density-independent factors have an increasingly greater effect as a population's density increases.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
