Answer:

The correct answer is A.

Explanation:

An osteoclast is large multinucleated cell present in the bone. Its main function is bone resorption, which occur when the osteoclasts secret hydrogen ions and many enzymes. As a result, bone matrix is digested by them. The most important enzyme is the protease cathepsin K, which degrades collagen.

Cathepsin K is regulated by parathormone, calcitonin and growth factor interleukin 6.

Matrix digestion is key during <u>bone fractures</u>, because it allows the repair and remodeling of the bone. But when this action is excessive, it can lead to osteoporosis (loss of bone density).

Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits. Mars
Mars Close Approach to Earth

Simply go outside and look up and, depending on your local weather and lighting conditions, you should be able to see Mars. That is the point in Mars' orbit when it comes closest to Earth, this time at about 38.6 million miles (62.07 million kilometers) from our planet. 24.8 million miles
Venus is closest to Earth at its inferior conjunction. The smallest distance this can be today is just under 24.8 million miles (40 million km). Their orbits rarely make this happen, but there is such a close approach in January 2022. Also, The Moon
A huge system of stars is called a galaxy. The Moon is the closest celestial body to our Earth. Earth is the third nearest planet to the Sun. Planets do not have their own heat and light.

Naily [24]

Answer: A) Layers 1 and 2.

Explanation:

Secondary succession refers to when species of plants and animals come back to recolonise an area that was destroyed by a natural disaster of some sort or human activity that change the makeup of the area but somehow left it still capable of supporting life.

As the species that come during secondary succession come after the land has been destroyed so to speak, they would be the later species to arrive which would mean that when they died they would be the closest to the surface when their body decays.

Secondary succession would therefore most likely be observed between layers 1 and 2.
