How can you test the idea that solar energy is required for the reduction of NADP+ to NADPH?
Answer:
In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.

ribozymes are rna molecules that have enzymatic activity. this conflicts with the belief of early molecular biologists that
Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

if a cell has 24 chromosomes, how many chromosomes would each of its four daughter cells have after meiosis?
Answer:
Because there are two rounds of division without duplication in between, the genetic content is cut in half. Each of the 4 daughter cells will only end up with half of the genetic content of the parent cell. Therefore, after meiosis, the daughter cells would have only 12 chromosomes each.

Answer:
organic molecules and carbon dioxide
Explanation:
Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas. Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ).

Why isnt there a solar eclipse during every new moon?
Answer:
Eclipses do not happen at every new moon, of course. This is because the moon's orbit is tilted just over 5 degrees relative to Earth's orbit around the sun. For this reason, the moon's shadow usually passes either above or below Earth, so a solar eclipse doesn't occur.
Explanation:
Make this in own words if it's for a test or smth

Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?
A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes
B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.
D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.
Answer:
your answer is B. The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.
These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.
