Answer:
Adrenaline
Explanation:
The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.
Answer:
2
Explanation:
Prokaryotic cells don't have a nucleus or membrane bound organelles
<h3><u>Answer;</u></h3>
C.) The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
<h3><u>Explanation</u>;</h3>
- Molecular clocks are used to date origin of species. They are based on the observation that random mutations accumulate in genes at a fairly constant rate
.
- Once a mutation rate is determined it can be used to establish dates of divergence of species.
- Molecular clocks can be used in putting a series of evolutionary events into chronological order, by comparing sequences from different species to determine when they last shared a common ancestor, in effect drawing the family tree.
Answer:
abiogenesis
Explanation:
Abiogenesis is the idea that supports the thought that the emergence of life is associated with the non-living things. It is believed that initially, the structure of the formation of life was simple. With further process, it turned to be complex. According to this hypothesis, the non-living matter of the Earth gave birth to the living matter.
In the given excerpt, the experiment performed by the evolutionists by using chemicals is an example of abiogenesis.
C. 8 * 10^-8 cm2
2*10^4=20000
20000*(4*10^-12)=8*10^-8
