Cells get raw materials- including water, oxygen, minerals and other nutrients from the foods you eat. They let in raw materials through the cell membrane: the thin, elastic structure that forms the border of each cell.
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:
water flows through the landscape. the condition of the land surface affects the flow and quality of water .
<h2>Correct answer is option "E"</h2>
Explanation:
- The citric acid cycle, otherwise called the Krebs cycle or tricarboxylic acid (TCA) cycle, is the second phase of cell breath. This cycle is catalyzed by a few compounds and is named to pay tribute to the British researcher Hans Krebs who recognized the arrangement of steps engaged with the citric acid cycle. The usable vitality found in the starches, proteins, and fats we eat is discharged for the most part through the citric acid cycle. Despite the fact that the citric acid cycle doesn't utilize oxygen legitimately, it works just when oxygen is available.
- In eukaryotic cells, the citric acid cycle utilizes one particle of acetyl CoA to produce 1 ATP, 3 NADH, 1 FADH2, 2 CO2, and 3 H+. Since two acetyl CoA particles are created from the two pyruvic acid atoms delivered in glycolysis, the complete number of these atoms yielded in the citric acid cycle is multiplied to 2 ATP, 6 NADH, 2 FADH2, 4 CO2, and 6 H+. Two extra NADH atoms are additionally produced in the transformation of pyruvic acid to acetyl CoA preceding the beginning of the cycle. The NADH and FADH2 atoms delivered in the citric acid cycle are passed along to the last period of cell breath called the electron transport chain. Here NADH and FADH2 experience oxidative phosphorylation to produce more ATP.
- Hence, the correct answer is option E " The amount of ATP would be reduced from a total of 38 ATP to 14 ATP"
