Answer:
8 min 20 seconds
Explanation:
Radiation from the sun travels as light through the vacuum of space. Therefore, it is travelling at the speed of light which is roughly 300,000 km/s. If we divide this speed by the average distance between the Sun and the Earth (150,000,000 km) we would get a total of 500 seconds. We can now turn this total time into minutes which would be roughly 8 min and 20 seconds. Therefore, it would take a total of 8 min 20 seconds for radiation from the Sun to reach Earth.

Explanation:
Why do traits that give an organism a disadvantage exist during meiosis? Please be as descriptive as possible and write it in your own words
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
Explanation:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
11. Circle the letter of where cells get the energy to regenerate ATP.
a. ADP
b. phosphates
c. foods like glucose
d. organelles
Answer:
c
ADP is what is missing one of the phospates that gets put on there to turn it into ATP which is done in mitochondria which is an organelle
Explanation:
Particular to plants and cyanobacteria is the process of photophosphorylation. During photosynthesis, it is the conversion of ADP to ATP utilizing solar energy. In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP. Thus, option A is correct.
What is the impact of ADP in ATP formation?The excess energy is stored by the cell by reuniting an unattached phosphate molecule with ADP, turning it back into ATP. This extra energy can come from the breakdown of food that has been ingested.
In the case of plants, energy produced during photosynthesis. The ATP molecule is comparable to a battery that can be recharged.
The cell uses ATP to generate energy. The energy source used by cells to carry out activities is ATP.
It can then replenish ATP by adding an inorganic phosphate molecule to ADP through a process known as cellular respiration.
Therefore, ADP of where cells get the energy to regenerate ATP.

does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Explain what incomplete dominance is
Answer:
Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism ’s resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance. One example is shown in roses.
