Zigmanuir [339]3 years ago
6 0

Answer:

Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-

Original fossils that are not very old.  e.g. teeth, skeleton, shells.

Frozen fossils

less permanent fossils

casts, molds,  and prints - wings, skin, leaves, etc.

The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.  

e.g. Archeopteryx is the connecting link between the reptiles and birds.

The modern horse Equus have several ancestor species, we came to know from the fossil records.

The fossil record shows the evolution of humans and their ancestors.

Distinguish between voluntary and involuntary actions.
sukhopar [10]
<h2>GREETINGS!</h2><h2>_____________________________________</h2>

<u>ANSWER</u><u>:</u>

<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>

Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.

<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>

the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.

<h2>_____________________________________</h2><h2>DIFFERENCES</h2>

1)      VOLUNTARY MUSCLES are under our control but INVOLUNTARY                 MUSCLES are not under our control

2)      VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles

3)      VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.

4)      VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.

5)      VOLUNTARY MSUCLES  require more energy. INVOLUNTARY MUSCLES require less energy.

What happens to the CO2 released by the body?
Sladkaya [172]

Answer:

When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.

Why does geographic isolation cause speciation?
zimovet [89]

Answer:

A. It allows two populations to evolve separately.

Explanation:

Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.

We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.

B is incorrect because it doesn’t apply.
