Answers

Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant  produced. This is common in premature infants.

Explanation:

Respiratory distress syndrome (RDS) is a well-known breathing disorder that is common in premature infants. It happens when there is a lack of surfactant produced in the baby's lungs which is quite bad because surfactant enables babies to breathe when they are born by keeping the lungs expanded.

It is common in premature infants because the lungs only begin to produce surfactant in the third trimester so babies that are born prematurely did not get to produce sufficient quantities. If not treated immediately, brain damage could follow.

1. What do you know about gravity?
2. How could gravity affect the water cycle?

Explain your answer.''

Answers

Explanation:

What do you know about gravity?

ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.

How could gravity affect the water cycle?

ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Which situation is the best example of secondary succession?

A) An organism survives a difficult winter

B) The population in an area remains the same

C) One species replaces another species in an ecosystem after a forest fire

D) Each of several species uses the same amount of resources

Answers

Answer:

The answer is C

Explanation:

Secondary succession often occurs after a disaster, the ecosystem is not as primary as the primary succession, so it will take shorter time to recover. New species will occur in this place, and rebuild a constant environment. C is exactly the situation.

Hope this will help❤️

The best example of secondary succession is when one species replaces another species in an ecosystem after a forest fire. The correct option is C.

What is secondary succession?

Secondary succession is a type of ecological succession that occurs on substrates that already have soil, and at least some organisms residing on it, like a forest or a community that has been disrupted by wildfire, tornadoes, or hurricanes.

The secondary succession in an ecosystem happens when a primary community is destroyed, for example, by wildfire. In secondary succession, the soil, seeds, and rhizomes survived in the soil and provides the foundation for the new community that is about to develop.

The rate of secondary succession varies according to the time taken for the primary community to regenerate, the level of disturbance of the habitat, the availability of propagules, and the dispersal capability of the species involved.

Therefore, the correct option is C.

to differentiate between agarose gel electrophoresis and SDS-PAGE based on the following criteria:
2.2.1 Composition of gels
2.2.2 Dye used for staining

Answers

Explanation:

Agarose has a large pore size and is suitable for separating nucleic acids and large protein complexes. ... SDS-PAGE separates proteins primarily by mass because the ionic detergent SDS denatures and binds to proteins to make them uniformly negatively charged.

In this question we will differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.

Agarose gel

The gel matrix is ​​created by dissolving a natural polysaccharide called dye-free agarose, which is derived from a type of seaweed, in a conductive buffer, in the approximate proportion of 1% to 3% agarose.

SDS-PAGE

Polyacrylamide gel electrophoresis (PAGE) with sodium dodecyl sulfate (SDS). SDS-PAGE consists of a type of electrophoresis performed under denaturing conditions for the separation of proteins without dyes.

Whit this information, we can conclude that differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.

Introduction, naturalization, colonization, and dispersal or spreading.

Explanation:

There are four main stages of invasion i.e. introduction, naturalization, colonization, and dispersal or spreading. In the first stage, the specie is introduced in the environment, in the second stage the specie adopt the environment, in the third stage the specie started growth and make colonies to increase its population and in the last stage the specie disperse in the environment through different means and spreading of that organism occur. The failing of adaptation to the environmental conditions leads to the failing of invasion of a specie.

Calcium is the most abundant mineral in the human body. Calcium ions are needed for bone mineralization and tooth health,
regulation of the heart rate and strength of contraction, blood coagulation, contraction of smooth and skeletal muscle cells, and
regulation of nerve impulse conduction. When blood levels of calcium get too high, the thyroid gland is stimulated to release
calcitonin, which initiates actions to lower blood levels of calcium.
Consider the role of calcitonin. ALL BUT ONE is the result of the release of calcitonin by the thyroid gland.
