Which diagram below shows the process of meiosis - Diagram A or Diagram B? How do you know? Explain all the details that prove you are correct.
Answers
From the diagram, meiosis is shown by the diagram in B in the question.
What is meiosis?Meiosis occurs when a cell divides in such a way that each daughter cell gets only half of the number of chromosomes in the parent cell.
Looking at the cell division in diagram B, we can see that there are only two chromosomes in each daughter nuclei out of the four chromosomes in the parent nuclei hence that us meiosis.

Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans
Answers
From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.
---------------------------------------
Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level. From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment. At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The progressive reduction of energy determines the number of trophic levels (4 or 5).If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.
5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.
1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.
164.5 MJ of this energy is tranferred to the following trophic level.

B. Lego pieces or building.
C. long chain compounds.
Answers
Answer: B
Explanation:
Monomers are atoms or small molecules that bond together to form more complex structures such as polymers (which are long chain compounds)
Monomers are long chain compounds. So, the correct option is (C).
What are Monomers?A monomer is defined as a molecule which can react with other monomer molecules to form a larger polymer chain. It is also a three-dimensional network formed by a process called polymerization.
These are the molecules of any of a class of compounds mainly organic compounds which can react with other molecules to form very large molecules known as polymers.
Examples of monomers are glucose, vinyl chloride, amino acids and ethylene where each monomer is linked to form different types of polymers like glucose, glycosidic bonds which link sugars to form polymers like glycogen, starch and cellulose binds monomers.
Thus, Monomers are long chain compounds. So, the correct option is (C).

https://brainly.com/question/25961570
Real-life fingerprinting differs from CSI techniques. While CSI portrays fingerprint analysis as rapid and foolproof, reality involves a slower and more nuanced process.
Real-life fingerprinting is a more involved process than the quick and ostensibly error-proof fingerprint analysis seen on CSI. CSI frequently depicts fingerprint matching as a straightforward database search that produces instant identification. However, in the actual world, fingerprint analysis is carried out by skilled experts who painstakingly check ridge patterns, minute spots, and other traits to assure precise matches. To avoid mistakes, this procedure can be time-consuming and requires knowledge.
In addition, the way that huge, networked databases are shown in CSI oversimplifies reality. Although modern technology makes fingerprint comparison easier, the vast network of records that are easily available is more fantasy than reality. Real-world law enforcement databases are subject to stringent guidelines and restrictions.

What is Milton Erickson?He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.
Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.
