The changes that occur during puberty are mostly a result of changes in hormone levels in the body.

<h3>Puberty</h3>

The transition from a child to an adult is caused by changes in the level of some hormones in the body.

In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.

In males, there is an increase in the production of testosterone hormone among many other hormones.

Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

What geologic activity occurs at continental- convergent plate boundaries?
Llana [10]

Answer:

A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

The location where two plates meet is called a plate boundary. Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains, volcanoes, mid-ocean ridges, and oceanic trenches.

baherus [9]

Answer:

At least 17 PCR cycles or 16 PCR cycles

Explanation:

As we know -

In one chain of  heating and cooling  of polymerase chain reaction (PCR), the strands of DNA gets doubled.

The general mathematical representation of this is

{2^n - (2 *  n)}

where "n" is the number of PCR cycles.

It is given that DNA strands  to be produced is 16 times the original quantity of DNA.

So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less  than 16 times the original quantity of DNA

What is it called when the forest remains but its richness and well-being have deteriorated?

Answer: Biodiversity loss

The biodiversity can be defined as the variety of life forms on earth or any other region. The forests are rich sources of biodiversity. The hunting, poaching, animal trafficking, and other ill-legal related human activities are like to reduce the species richness in forests. As many species are dependent upon other species for food, mate and other requirements for completing the life cycle thus the well-being of the forests will get deteriorated by the loss of biodiversity.
