what is the G1 phase of mitosis and what happens during this phase?


actually environmental science own words please need it now.

Answers

Answer 1

Answer:

G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. In G1, cells accomplish most of their growth; they get bigger in size and make proteins and organelles needed for normal functions of DNA synthesis. Here, proteins and RNAs are synthesized, and, more especially the centromere and the other components of the centrosomes are made.

When a protein molecule permanently changes its shape on being heated, this is
known as _____
What word completes the sentence?​

Answers

Such a process is known as denaturation. In this case where a protein "permanently" changes its shape (i.e., denatures) on being heated, the protein is irreversibly denatured.

When a protein molecule permanently changes its shape upon being heated, this is known as denaturation. It broke the shape of the protein.

What are proteins?

Proteins and nucleic acids can get denaturized when they are exposed to high temperatures, pH extremes, non-physiological quantities of salt, organic solvents, urea, or other chemical agents.

Denaturation is a biological process that alters a protein's molecular structure. Denaturation is the name given to such a process. A protein is irreversibly denatured when it undergoes a “permanent” change in shape (i.e., denatures) in response to heat.

Therefore, denaturation is the process by which a protein molecule undergoes a permanent change in form when heated. Thus, the word that completes the sentence is denaturation.

What is the Cell cycle?

The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. It can significantly be divided into two phases. They are as follows:

Interphase.M-phase (Division phase).

The Interphase of the cell cycle is the longest phase which consists of three phases. They are the G1 phase, S-phase, and G2 phase. In this phase, the cell replicates its genetic content and appears to be in a normal state.

In metaphase, the chromosomes usually align in one plane and form an equatorial plate. Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and centromeres migrate to opposite poles.

In telophase, two sets of daughter chromosomes reached the opposite poles and are converted into chromatin thread. After karyokinesis, the cytoplasm gets converted into two equal parts. This is known as cytokinesis.

Therefore, the letter answers to the matching image is well described above.

6. It is a criticism of many population ecologists that the pattern of population increase and frequent crash of the deer
population would have occurred even if the bounty had not been placed on the predators. Do you agree or disagree with
this statement? Explain your reasoning.

Answers

Answer:

I disagree with this statement.

Explanation:

I disagree with this statement because predators do have a place in ecosystemsto keep prey species from becoming overpopulated, therefore the extent of theoverpopulation would most likely have been much less if the natural predatorswere allowed to play a role in controlling the deer population.

Natural predators and prey have a beneficial interaction. Disagree with the assertion since predators have a big impact on controlling the size of their prey population and preventing overpopulation.

What is the population?

The population reaches a maximum point that is determined by the amount of space or food that is available. The carrying capacity, or K, is the equilibrium point where the natality and mortality rates are equal to one another. K is a constant that equals population size at this point.

However, the predator-prey interaction that exists in the presence of a predator causes the deer population to drop.

Therefore, disagree because predators are crucial in controlling the size of their prey's population and preventing overpopulation.

What color is ragweed pollen

Explanation:

The color which can be attributed to the ragweed pollen when it is been analyzed can be regarded as greenish yellow.

How can the color of ragweed be described?

Ragweed has tiny heads of greenish yellow blooms that produce large amounts of pollen that is dispersed by the wind rather than insects. While ragweed blooms are not particularly eye-catching, it is frequently simpler to identify these plants by their stems and leaves.

In the aster family, Asteraceae, the genus Ambrosia contains flowering plants known as ragweeds. They are found across the Americas' tropical and subtropical climates, particularly in North America, where the southwestern United States and northwest Mexico are the genus's origin and diversity core.

[tex]\boxed {\tt 2nd \ Answer}[/tex]

Explanation:

An enzyme is a protein that speeds up a chemical reaction. Enzymes are shape specific. The active site is a specific shape, which means it can only break down specific substrates.

Certain conditions can denature enzymes. For example, extreme temperatures or pH will cause the enzyme to deform and change shape, which means it cannot perform its job.

Therefore, the best choice is the second one: enzymes work best in specific conditions and only break down specific substrates.
