2AP
ROCKER
173 terawatts
1.73 terawatts
17,300 terawatts
173,000 terawatts
Answers
D. 173,000 terawatts
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.The Earth receives ≈174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.Since, 1PW=1000TW
Thus, 174 PW= 174*1000=174,000 TW.
Therefore, correct option is D.

How are meiosis and mitosis different?
Answers
Answer:
Function. Mitosis is for the growth, development, repair of damaged cells and replacement of damaged cells in multi-cellular organisms. Meiosis is the production of gametes for sexual reproduction.
Location it takes place in. Mitosis takes place in all somatic cells! Meiosis takes place in the testes and ovaries. (In humans)
Number of daughter cells produced by a single parent cell. Mitosis produces 2 daughter cells from 1 parent cell. Meiosis produces 4 daughter cells from 1 parent cell.
Number of chromosomes each daughter cell contains. In mitosis, each daughter cell contains a diploid number of chromosomes. (2n) In meiosis, each daughter cell contains a haploid number of chromosomes. (n)
Presence of crossing over stage in Prophase. In mitosis, there is no crossing over (homologous recombination) that occurs in Prophase. In meiosis, there is crossing over (homologous recombination) that occurs in Prophase.
Genetically identical to parent cells? In mitosis, daughter cells are clones of their parent cell. Hence they are genetically identical to each other. In meiosis, daughter cells are genetically different to their parent cells as they contain different genetic codes due to crossing over that had led to the recombination of genes between homologues during Prophase I.

A small group of birds became isolated from a large population when deforestation occurred for the development of new buildings. Over the course of a few generations, the gene pool of the small group became drastically different from the original population. Which of the following best describes this occurrence?
A selective process caused an increase in the population's genetic variation.
The founder effect caused the chance event that altered the allele frequency.
Bottleneck effect led to over-representation of certain alleles in the new gene pool.
Gene flow led to an increase in the gene pool's allele frequencies.
Answers
I'm thinking it's the founder effect, which according to something I found on the Internet is genetic variation from when a population originates from a small amount of species.
Bottleneck effect led to over-representation of certain alleles in the new gene pool. Therefore, option (C) is correct.
What is The bottleneck effect?
The phenomenon known as the bottleneck effect takes place when a population suffers a significant decrease in size, which leads to a reduction in the amount of genetic variation in the population. In this hypothetical situation, the clearing of land for new construction and the introduction of new structures led to a small group of birds becoming cut off from the larger, original population of birds.
Due to the fact that this small group was kept apart from the larger population, a phenomenon known as a bottleneck effect occurred. This caused the gene pool to become strikingly dissimilar to that of the original population as a result of the overrepresentation of certain alleles in the new gene pool. As a result, the response that should be chosen is option C.

2. animals eat plants and produce carbon dioxide and water how do you animals affect the amount of carbon in the earths atmosphere
Answers
Hope that helped
Animals eat plants and produce Carbon-di-oxide. Due to this, the concentration of carbon increases in the Earth's atmosphere by the carbon cycle.
What is the carbon cycle?The carbon cycle is a biogeochemical cycle in which the exchange of carbon between the environment and the organisms occurs.
Plants are producers, they absorb carbon-di-oxide from the environment, and by the process of photosynthesis, they convert it into an organic molecule (glucose). When these plants are consumed by consumers, carbons enter the food chain. It transfers from primary consumers to secondary consumers and then tertiary consumers.
When the consumer respires, carbon is released into the environment in the form of carbon-di-oxide. When these animals die, their bodies decompose and carbon is absorbed again into the atmosphere.
Thus, this is how animals affect the amount of carbon in the atmosphere.

What is the relationship between wavelength and frequency?
What is the relationship between frequency and energy?
(any troll answers will be reported)
Answers
Gamma rays have the highest frequency (waves are close together/short wavelength)
Highest wavelength is red (distance between peaks is longest), lowest wavelength is violet (distance between peaks is shortest)
Gamma rays have the most energy (highest frequency) and are the most dangerous
Wavelength and frequency have an inverse relationship. As wavelength increases, frequency decreases and visa versa.
Frequency and energy have a direct relationship. As frequency increases, energy increases.
Answer:
See below.
Explanation:
● Gamma rays have the highest frequency.
○ The highest wavelength will be for red while the lowest wavelength will be for violet.
● Gamma rays are more dangerous & also have more energy.
○ Wavelength & frequency have an indirecly proportional relationship.
● Frequency & energy have a directly proportional relationship.

What is needed in order to give the DNA polymerase a place to start copying DNA? How long is it? What puts it on?
Answers
DNA polymerases add nucleotides to the 3′ end of a polynucleotide chain. ... To initiate this reaction, DNA polymerases require a primer with a free 3′-hydroxyl group already base-paired to the template. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
