Answer:
<em>The correct option is A) an increase in oxygen levels, which led to the extinction of many anaerobic organisms.</em>
Explanation:
Photosynthesis can be described as a process in which food (glucose) is produced by photosynthetic organisms by using carbon dioxide, water along with light energy from the sun. Oxygen is released as a by-product of this reaction. The process of photosynthesis initially allowed for oxygen gas to get accumulated in the air. This caused the rise of aerobic organisms who required oxygen for respiration. Before the photosynthesis organisms evolved, there was not enough oxygen gas on earth to support the life of aerobic organisms.
The molecule is formed from glucose, which fits together nicely and becomes sturdy. It relates to the function of the cellulose model because it aids in strength and structural support.
Answer: c. enhanced sense of smell.
Explanation:
Primates are an incredibly diverse group of living species between 190 and 350 based on various taxonomic structures and show a broad variety of characteristics that help differentiate them from other mammals.
The hands ofprimates are particularly sensitive and contribute to the sense of contact. Relative to other mammals, the brain areas that deal with eye-hand coordination and stereoscopic are very good and vision are especially large.
The smell characteristics decreases to survive for animals which develop a dependence on other senses, such as hearing or sight.
Hence the correct option is c. enhanced sense of smell.
Minerals are related to compounds and elements.
A mineral is defined as a naturally occurring substance that has a definite chemical composition and crystal structure.
Most minerals are made of two or more elements that are chemically combined together to form a compound. Others such as gold or copper are made of a single element. Minerals are grouped according to their chemical composition or makeup.
A mineral is always a solid and has a definite shape and volume and always has a characteristic crystal structure.
If I understand the question correctly the answer should be 4500 eons.
Hope this helps!
