The source of the oxygen released into the air as a product of photosynthesis is C) Water only.
Answer:
The answer is A. There is more genetic variation in organisms that reproduce sexually than those that reproduce asexually.
Explanation:
This is because offspring with two parents can get genetics from both family's which means there is a chance for many different types of characteristics.
If an offspring only has one parent however, the offspring will only get those genetics from the parent which means there are not many possibilities for offspring to look or act different then their parent.

The pancreas is a six-inch-long gland located in your abdomen near your liver and part of the small intestine. It’s nestled right behind and slightly below your stomach and in front of your spine. The head of the pancreas is along the curve of your duodenum, the first part of the small intestine just beyond the stomach.
The pancreas plays a dual role in your bodily functions:
Endocrine system. The pancreas secretes hormones, including the blood sugar-regulating hormones: insulin and glucagon.
Exocrine system. The pancreas also secretes enzymes into your digestive tract through a duct into your duodenum.
D. Precambrian
<span>The Precambrian Era is the longest geological era beginning 4.5 billion years ago and lasting approximately 4 billion years. The Precambrian era is generally separated into two eons the first of which being the Archaean Eon. spanning from around 4.5 billion years ago to 2.5 billion years ago, during this time air temperatures lowered and the water vapour condensed forming the first primeval oceans. This was a period of great volcanic activity when immense lava flows solidified both on the surface and below were transformed into rocks which were then carried by the first rivers to oceans where they were deposited at the bottom of the oceans forming the first sediments. The second eon was the Proterozoic Eon spanning from 2.5 billion years ago to 500 million years ago. </span>
