Answer:
10
Explanation:
according to newton's second law f=ma. so a= f/m. then a= 20/2 = 10
<span>Organic Chemistry is so important in the study of Biology because most reactions in Biology are organic reactions. Organic chemistry is the study of structure, properties, and reactions of organic compounds</span>
Answer:
The human gene for your muscle protein is different from monkey muscle protein in 4 places and different from a chicken's gene in 25 places.
This is molecular biology, and this shows a little bit about evolution because it shows human, monkey and chickens share a common ancestor.
Explanation:
The example shows some features about biology. Molecular biology is focused on all the components and elements of molecular cells. In this case, analysing muscle protein and genes is considering this type biology.
DNA is the origin of every living cell on earth and is unique for every species. The analysis of protein's DNA is a determination of how distant or close species are.
There are many other ways to relate evolution to the different animals, species or cells. You can use fossil record, anatomy, reproductive isolation, embriology, among many others.
Answer:C
Explanation:
It is important for the cell not to activate glycolysis and gluconeogenesis at high rate simultaneously because it is expensive for the cell.
In the break down of one molecule of glucose to pyruvate, one ATP is used in the conversion of glucose to glucose-6-phosphate and one ATP is used in the conversion of fructose-1-phoshate to fructose-1,6-biphosohate. While a total of four ATPs are produced.
Making it a net gain of 2 ATP in glycolysis.
Gluconeogenesis produces no ATP and requires equivalents of 6 ATP (4 ATP and 2GTP) for one molecule of glucose produced.
(Glycolysis +2ATP) + (gluconeogenesis -6ATP) = -4ATP
There's a net loss of 4ATP if both reactions are activated simultaneously.
