Complete question:

This model of the cell cycle includes two arrows that each represent a process in the cycle.

What do the two arrows represent?

A. Arrow 1 represents prophase, and arrow 2 represents interphase.

B. Arrow 1 represents mitosis, and Arrow 2 represent meiosis.

C. Arrow 1 represents interphase, and Arrow 2 represents mitosis.

D. Arrow 1 represents meiosis, and Arrow 2 represents prophase.

(You will find the cycle in the attached files)

Answer:

C. Arrow 1 represents interphase, and Arrow 2 represents mitosis.

Explanation:

When we talk about the whole cell cycle we are referring to the interphase and the cell division (mitosis or meiosis).

Interphase: Represented in the cycle by arrow 1.

The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.  

• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.  

• During the S stage occurs the DNI replication process. At this point, also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.  

• G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.

Once the whole interphase is completed, mitosis occurs.

Mitosis: Represented in the cycle by arrow 2.

Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the cell separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles. Sister chromatids are held together until they reach the Anaphase, during which other enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles. In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, occurs cytokinesis.

Explanation:

Answer:

The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.

Explanation:

mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.

Explanation:

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

Answer:

Air pollution

Contributes to global climate change.

Answer:

amplitude, wavelength, frequency, and speed.

Explanation:  Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast. Water waves are the focus of our Tsunamis and surf resources, but many other kinds of wave exist. These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.

Explanation:

The inheritance of multiple phenotype genes that is the mother will have heterozygous as well as the father will have the heterozygous condition as well. The process is included in  genetics and the genetics is related to it.

It is defined as the study of genes and study of genes expression along with all the genetic factors associated with it.

The expression of the hair that is expressed in the progeny of the parents where the multiple expression is present can show incomplete dominance as well where none of the phenotype that is the alleles and the genes that are present in the parents will not express it in the child.

The process is also called as recombination where both the traits re expressed in the child and the characters both associated with the parents will express in the child.

Explanation:

Answer:

Apoptosis is an orderly process in which the cell's contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell's contents spill out and cause inflammation. Apoptosis removes cells during development.

Apoptosis is a form of programmed cell death that occurs in multicellular organisms.

It is a  natural biological process of programmed cell death in which the cells destroy themselves and maintain the smooth function of the body parts.

There are two types cell death such as Programmed death of cells or apoptosis and uncontrolled death or Necrosis.

Apoptosis can occur via two pathway such as Extrinsic Pathway is triggered in response to external stimuli, ligand binding at death receptor and these receptors are called as Tumor Necrosis Factor gene.

Intrinsic Pathway triggered in response to internal stimuli such as biochemical stress, DNA damage and this pathway is modulated  Bax, and Bcl-2 molecules.

Apoptosis helps in maintaining homeostasis, proper size of the body, cell number, elimination of unwanted cell, T-lymphocytes etc.

A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota

Explanation:

Corks are a type of plant part that is eukaryotic cell having well developed nucleus.

Cork cells are dead cells found in the bark of stems. They appear hexagonal or pentagonal under a microscope. In 1665, Robert Hook used a microscope for the first time to examine cork cells.

Plant cells that mature into mature cork cells form the protective water-resistant tissue in the outer covering of stems or trunks.

Cork cells are genetically programmed not to divide and, as a result, are considered dead cells.

Eukaryotes are organisms with nuclei and other membrane-bound organelles. Eukaryotic organisms include all animals, plants, fungi, and protists, as well as the majority of algae.

Thus, it can be concluded that the corks are eukaryotic cells.
