19. the binding energy per nucleon of a nucleus is 3 mev. what is the minimum energy needed to completely separate the nucleons of ?

Answers

The minimum energy needed to completely separate the nucleons of the nucleus is known as the binding energy of the nucleus.

The energy needed to completely disassemble a nucleus into its component protons and neutrons is known as the binding energy of a nucleus.

Given that each nucleon in a nucleus has a binding energy of 3 MeV, the total binding energy of the nucleus would be equal to three times the number of nucleons.

This indicates that the total binding energy of the nucleus is equal to the minimal energy needed to entirely separate the nucleons of the nucleus.

The energy required to separate the nucleons of the nucleus must be at least 3 MeV per nucleon, which is the same as the nucleus's binding energy.

Answer:

There is no correlation/connection between number of chromosomes and complexity of an organism.

Explanation:

If the number of chromosomes determined the complexity of an organism, we could say that the kiwi in this problem is more complex than the human, however, this is not true. A chromosome is like a container for the genetic material (genes) of an organism, it doesn't matter how many containers there are, but rather what's inside the containers that determine genotype and phenotype.

Answer:

Not much.

Explanation:

Considering the fact that banannas have like half of the chromosomes that a living animal has, and the fact that an animal somehow has more chromosomes than a human, leads me to believe there is little to no correlation with the amount of chromosomes someone has and their complexity.

NOT true?
A always pairs with T
C always pairs with G
T always pairs with G
T always pairs with A

Answers

Answer:

T always pairs with A

Explanation:

I think so I'm super sorry if its wrong :)

According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.

What is base-pairing in DNA?

Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.

Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs

Although they keep the two strands of DNA together, they are not strong enough to withstand replication.

Therefore, the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, hence option C is correct.

During the initiation step of translation, the fmet charged trna assembles in which site of the ribosome?

Answers

P site, initiation step of translation, the fmet charged tRNA assembles in this site of the ribosome.The small ribosomal subunit, mRNA, initiator tRNA, and large ribosomal subunit come together to form the initiation complex. The P site of the completed ribosome is where the initiator tRNA is located.

When an amino acid, tRNA, and mRNA come together inside the ribosome, translation begins. The process of translation continues as the mRNA passes through the ribosome after it has started. Each codon pairs with a new tRNA anticodon, bringing in new amino acid to lengthen the chain.

At the subunit interface, tRNA molecules bind to the ribosome in a solvent-accessible channel. The big and small subunits each feature three tRNA binding sites known as the aminoacyl site (A site), peptidyl site (P site), and exit site (E site). The expanding polypeptide chain of amino acids is held in place by the tRNA by the P site, also known as the peptidyl site. The new amino acid that will be added to the polypeptide chain is stored in the aminoacyl tRNA, to which the A site (acceptor site) binds.

csccs that develop from well-differentiated cells manifest as scaly nodes and plaques while poorly differentiated cells that become csccs develop as soft and hemorrhagic lesions

Answers

In conclusion, the degree of differentiation in csccs determines their appearance and characteristics. Well-differentiated csccs manifest as scaly nodes and plaques, while poorly differentiated csccs develop as soft and hemorrhagic lesions.

The csccs (cutaneous squamous cell carcinomas) that develop from well-differentiated cells exhibit scaly nodes and plaques, while poorly differentiated cells that become csccs result in soft and hemorrhagic lesions.
To break it down:
- Well-differentiated csccs present as scaly nodes and plaques. These types of csccs typically have cells that closely resemble normal skin cells and are organized in a more orderly manner.
- On the other hand, poorly differentiated csccs display soft and hemorrhagic lesions. In this case, the cells are less organized and resemble less mature skin cells.
In conclusion, the degree of differentiation in csccs determines their appearance and characteristics. Well-differentiated csccs manifest as scaly nodes and plaques, while poorly differentiated csccs develop as soft and hemorrhagic lesions.

Which statement best describes chromatin associated with actively transcribed genes as compared to chromatin associated with genes which are not being actively transcribed?
More compacted and more acetylated
More relaxed and more acetylated
More relaxed and less acetylated
More compacted and less acetylated

Answers

The best statement that describes chromatin associated with actively transcribed genes as compared to chromatin associated with genes which are not being actively transcribed is "More relaxed and more acetylated".

The chromatin associated with actively transcribed genes is more relaxed and more acetylated as compared to chromatin associated with genes that are not being actively transcribed. The chromatin is composed of DNA and histones and can be modified to enable or prevent gene expression.

The relaxation of the chromatin allows transcription factors to access and interact with the DNA while the acetylation of the histones creates a less compact chromatin structure that enables easier access of the transcription machinery to the DNA template.This relationship of chromatin structure with transcription is known as epigenetics. Epigenetic modifications are changes to the DNA that affect gene expression without changing the DNA sequence. Acetylation is one of the most common epigenetic modifications that occurs on the histone tails.

DNA replication is the process through which DNA duplicates. It occurs in the interphase and involves different enzymes, DNA molecules, and free nucleotides. Terms and definitions in the attached files.

What is DNA replication?

DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.

The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.

DNA strands are antiparallel, and replication occurs only in 5'-3' direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

A population of 40 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can
sustain up to 600 deer. Absent constraints, the population would grow by 60% per year. Estimate the population
after one year Pi Estimate the population after two years P2 -

Answers

The population of deer in the wildlife sanctuary can be estimated using the formula:

P(t) = P(0) * (1 + r)^t

where P(t) is the population after t years, P(0) is the initial population, r is the growth rate per year, and t is the number of years.

In this case, the initial population (P(0)) is 40 deer, the growth rate (r) is 60% per year (0.60), and we need to estimate the population after one year (P1) and two years (P2).

To calculate P1:
P(1) = 40 * (1 + 0.60)^1
P(1) = 40 * (1 + 0.60)
P(1) = 40 * 1.60
P(1) = 64

Therefore, the estimated population after one year is 64 deer.

To calculate P2:
P(2) = 40 * (1 + 0.60)^2
P(2) = 40 * (1 + 0.60)^2
P(2) = 40 * 1.60^2
P(2) = 40 * 2.56
P(2) = 102.4

Therefore, the estimated population after two years is 102.4 deer.

It's important to note that these are estimates and assume that there are no constraints on the population growth. In reality, factors like limited resources, predation, and disease can affect the growth rate and population size.

There is a net diffusion of water out of an animal cell when it is placed in a hypertonic blank solution.

The ideal osmotic environment for a plant cell is hypotonic a blank environment.

An isotonic environment is the ideal osmotic environment for animal cells. Animal cells have the same concentration as the cytosol. The penetration rate is the same on both the inside and outside sides. There is no increase or decrease in water or solvent concentration.

Plant cells are bloated and generally healthiest in a hypotonic environment where water uptake is ultimately balanced by walls that are pressed against the cell. This is considered normal. When a plant cell is surrounded by a solution containing a higher concentration of water molecules than the solution inside the cell water enters the cell by osmosis and the plant cell swells.
