The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.
Explanation:
In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.
The sea-level got drop due to global cooling of that time.
This resulted in continental drift making land connection of Africa with Eurasia.
The primates started migrating through this route.
The African forest become dry causing selective pressures in primates.
The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.
The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.
The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.
<h3>What is muscle contraction?</h3>
It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.
<h3>Characteristics of muscle contraction</h3>
- In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.
- The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.
- To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.
Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.

Gregor Mendel was a scientist born in the Austrian Empire in 1822. He
conducted pea plant experiments and established many of the rules of
heredity. He was explaining the significance of invisible factors ( now
called genes ) for the inheritance. He also experimented with hawkweed
and honeybees. Mendel is referred to as "The Father of Genetics".
Answer: Genetics.
Answer:
Zinc. (Ans. B)
Explanation:
Trace minerals: Trace minerals are defined as the inorganic molecules which are necessary for the human body for the different functions.
Zinc function in human metabolism is defined as a cofactor for numerous enzymes. Zinc play a role as a catalyst in a broad range of reactions. It is involved in the metabolic pathway directly or indirectly with lipids, carbohydrates, proteins, energy metabolism, and they are also important for the cell division process.
They also need for tissue and growth repair, and for reproductive development also. It's also played a vital role in immune system such as wound healing or required for the function and structure of the skin.
I think it might be metaphase because all of the chromosomes are lined up in the middle :) either that or anaphase!
