The mutation you are talking about is called: somatic mutations
These mutations occur in non-reproductive cells and they will not be passed off onto offspring.
I hope this helps!
Explanation:
Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 65million years a couple of things can happen:
- Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.
- The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.
- Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.
All these factors will eventually have a prolonged effect that combine to force dinosaurs into extinction.

Answer:
A
Explanation:
They form in mountains and flow through mountain river valleys. Glaciers cause erosion by plucking and abrasion.
Answer:
These organisms are a part of the kingdom Archaebacteria (otherwise known as just "Archaea")
These organisms are a part of the kingdom Archaebacteria (otherwise known as just "Archaea"), which consists of bacteria. ... This, archaebacteria undergo anaerobic respiration. This is a characteristic that allows such organisms to live in the harsh conditions in which they are found.
Answer:
According to the sliding-filament model of contraction, the muscle contraction occur due to the myosin heads propel the actin myofilaments toward the center of the sarcomere. This pulls the Z disks closer together, shortening sarcomere and the entire muscle
Explanation:
In the muscle fiber there are two proteins that facilitate the process of contraction, myosin and actin. Myosin is thicker and more abundant than actin, and its interaction is responsible for the process of muscle contraction.
Both molecules, myosin and actin, form bonds -called cross bridges- where the myosin heads produce the mobilization of actin towards the center of the sarcomere. Z discs are associated with actin myofibrils, so they come close, and promote the shortening of the sarcomere.
This process requires the action of calcium ions, which depolarize the muscle cell and consume energy in the form of ATP.
It should be noted that the myosin and actin molecules do not change their length, but their action causes the muscle fibers to shorten during contraction.
