Which of the following is not true about the rock layers?

Answer:

1. dna needs to be replicated before mitosis so that the parent cell has the same amount of genetic material as the parent cell once it has split.

2. helicase is an enzyme that is so dna can unwind.

Explanation:

the explanation is in the answer.

I hope this helps!

Answer:

DNA must be replicated before mitosis so that both identical daughter cells contain the same amount of genetic material as the parent cell once it has split in two. Helicase is an enzyme necessary at the initiation of DNA replication to unwind/unzip the DNA so that this process may begin.

Answer:

BB and BB

Explanation:

BB is a homo-zygous allele and both of the parent guinea pigs are homo-zygous.

A black coat is dominant over a white coat in guinea pigs. The genotypes of the parents are BB and BB. The correct option is d.

The terms genotype and phenotype relate to the individual's alleles and the observable traits that are generated from the genotype and determined by the dominance of the alleles, respectively.

For black coat = B

For White coat = b

A homozygous black pig is mated with another homozygous black pig. Homozygous means only one character will be shown in the genotype, that is the dominant and the dominant trait is black, B so, the genotype will be BB and BB. Recessive traits are hidden that do not show, and that is also black.

Therefore, the correct option is d. BB and BB.

Answer:

Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land - meandering - or going around objects such as hills or large rocks.

Answer: No because each have an important impact on humans.

Explanation:

Answer:

C

Explanation:

The data shows that each phenotype occurs about one-fourth of the time. That means that there are about equal numbers of purple-stemmed and green-stemmed plants, and about equal numbers of green-leaf and yellow-leaf plants. Of the four choices, answer A can be eliminated because all of the offspring of an ANL/ANL plant will have purple stems. Answer D can be eliminated because all of the offspring of two anl/anl parents will have green stems.

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.

Answer: the chemical messages will impact the cells resulting in change to gene expression

Explanation:

The specific function of signal cells releasing chemical messages to nearby cells during early embryonic development is the chemical messages will impact the cells, resulting in a change in gene expression. The correct option is A.

The growth and formation of the human embryo are known as human embryonic development or human embryogenesis. It is distinguished by early developmental processes in the embryo, such as cell division and cellular differentiation.

The endoderm, mesoderm, and ectoderm are three germ layers that develop throughout this process, known as gastrulation. Different components of the organism will develop from the cells in these three levels.

Therefore, the correct option is A, The chemical messages will impact the cells, resulting in a change in gene expression.

Answer:

The correct answer is - A patient's own tissue - an autograft and tissue from another person - an Allograft.

Explanation:

If the bone or the tissue is transferred from one point of the body to another point of the same person's body, this is called an autograft and is also thought of as "gold standard". It has a low level of risk in comparison to other grafts. It is used for surgical reconstruction.

An allograft is the transfer of the tissues or bone of an individual to the body of another individual of the same species during the surgical process. This type of graft has some risk of compatiblity.

Wires made of conductors have low resistance. The correct option is C.

Conductors are materials that allow the flow of through them. Insulators are those materials that prevent electricity from passing through them.

Copper, aluminum, gold, and silver are a few examples of common conductors. Wood, rubber, plastic, and glass are a few typical insulators.

A conductor is an object or kind of material that permits the movement of charge (electric current) in one or more directions.

This term is used in both physics and electrical engineering. Metal-based materials are frequently used as electrical conductors.

Low resistance to the flow of electricity is provided by good conductors like copper, aluminum, etc. They do so because they have a lot of free electrons.

There are no free electrons in insulators. As a result, despite applying voltage across them, essentially no electric current flows through them.

Thus, the correct option is C.

Hair plays an important role in our lives. The hair on our head keeps us warm and acts as a cushion for our skull. Hair appearance can also help form our identity and self-image, which makes hair loss very troubling.

Most hair disorders aren’t serious, but they are often considered major cosmetic issues that require treatment. Androgenetic alopecia is the most common form of hair loss, although there are a number of other hair conditions that can affect the scalp and other parts of the body.

Explanation: Protozoans are a single-celled microscopic animal of a group of phyla of the kingdom Protista, such as an amoeba, flagellate, ciliate, or sporozoan.

Protozoans play important roles in the fertility of soils. By grazing on soil bacteria, they regulate bacterial populations and maintain them in a state of physiological youth— in the active growing phase. This enhances the rates at which bacteria decompose dead organic matter.

homeostatic protection, mechanical protection, circulation

Explanation:

Homeostatic protection: cerebrospinal fluid transports polypeptide hormones and its PH allows for cerebral blood flow as well as pulmonary ventilation

Mechanical protection: cerebrospinal fluid absorbs shock, so that energy from an impact does not directly first affect the spine

Circulation: helps allow for the exchange of nutrients between the blood and adjacent nervous tissue
