Show how evolution could have occurred by the process of natural selection

Biology
1 answer:
Karo-lina-s [1.5K]3 years ago
4 0

Natural selection is basically a way for nature to choose what works and what doesn't work.  For example, if an animal was born with webs to swim, but most of its food source can be gotten on land, then the animal will die off until it evolves to go on land.  That is how evolution works with natural selection.  In the past long ago, millions of years back, animals in the water needed oxygen to breath, but the water started to lose it.  The land had air, and then the fish slowly grew legs, and their gills would evolve to lungs.  Eventually they would be able to roam the land.  Because there was so much oxygen with all of the shrubs, trees, and plants, that allowed the bodies of animals to grow big.

Travka [436]

Answer:

Option C, coracoid process of the scapula

Explanation:

Coracobrachialis muscle is one of the essential muscles that is responsible for the movement of elbow along with biceps brachii and triceps muscles.  

The coracobrachialis arises from the coracoid process of the scapula. It assists the elbow in flexion and internal rotation. Musculocutaneous nerve passes through the Coracobrachialis muscle and terminates at the lateral end of the cutaneous nerve of the forearm. However, the Coracobrachialis terminates at the humerus and its medial surface

Hence, option C is correct

How is the size of a planet related to the thickness of its atmosphere
Butoxors [25]
<span>Many planets are made of gas, and in different situations, the atmosphere can be destroyed.

The sun which is burnt measures atmosphere and in the same case planets can be in a good situation on galactic map and a great condition in the atmosphere as well as earth.
For example, the mass of an object can attract a smaller object causing gravity. The bigger the masses of a planet when it is in the right condition the more atmosphere it can attract if there is any floating on the planet. If it is big it will make a gravitational influence and gather more gases.</span>
