how many chromosomes are represented in each cell?
Answer:
46
Explanation:
A mutation in body cells do not affect future generations, but mutations in gamete (sex cells) will affect future generations.
A.True
B.False
Answer: A. True
Explanation:
Answer:
True
Explanation:
Only hereditary mutations, which occur in egg or sperm cells, can be passed to future generations and potentially contribute to evolution. Some mutations occur during a person's lifetime in only some of the body's cells and are not hereditary, so natural selection cannot play a role.

why is active transport needed to take mineral ions into the cytoplasm of the root hair cell?
Answer: In plants, they need to move mineral ions from the soil into the roots. Mineral ions are more concentrated in the cytoplasm of plant cells than in soil water or dillute.
Explanation:
Minerals cannot be soaked up through osmosis since it only involves the movement of water. Because the minerals are in such low concentration, they cannot be absorbed through diffusion. Active transportation is used instead.
What is active transport?Active transport refers to the transport of molecules or ions into or out of a cell via the cell membrane, from a low concentration region to a high concentration region.
The particles use the energy released during respiration to move against the concentration gradient.
Active transport is defined as the movement of molecules against a gradient from a region of lower concentration to a region of higher concentration.
Active transport in plant root hairs allows plants to absorb mineral ions, which are required for healthy growth, even though the concentration of minerals in the soil is usually lower than in the root hair.
Thus, active transport is needed to take mineral ions into the cytoplasm of the root hair cell, as there is a need to move the minerals from the region of lower to higher concentration.

Answer:
When the skin is injured, our body sets into motion an automatic series of events, often referred to as the “cascade of healing,” in order to repair the injured tissues. The cascade of healing is divided into these four overlapping phases: Hemostasis, Inflammatory, Proliferative, and Maturation.

Plz help ASAP on a timer
Answer: It is a cell
Explanation: Most cells have a honey cone shape.
The image represents the level of organization known as tissue. In the image, the cells are organized into a specific pattern and shape to form a tissue. It is important to note that different tissues can be organized into organs, and organs can be organized into organ systems, which make up the various body systems.
What is a Tissue?A tissue is a group of similar cells that work together to perform a particular function. Tissues can be found in many places in the body and they are specialized to carry out specific functions. For example, muscle tissue is composed of cells that contract and allow movement, while nerve tissue is made up of cells that transmit electrical signals.
The different levels of organization in the body are all interconnected and work together to maintain homeostasis and keep the body functioning properly.

A student claims that the Y chromosome contains the sex-determining region gene, known as the SRY gene, which causes male fetuses to develop testes.
Which of the following provides correct information about cell signaling that supports the claim?
A student claims that the Y chromosome contains the sex-determining region gene, known as the SRY gene, which causes male fetuses to develop testes.
The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
A
The SRY gene produces a protein that deletes portions of the X chromosome in males so that male characteristics can develop.
The SRY gene produces a protein that deletes portions of the X chromosome in males so that male characteristics can develop.
B
The SRY gene produces an RNA segment that is exported from specific cells and targets the developing gonads.
The SRY gene produces an RNA segment that is exported from specific cells and targets the developing gonads.
C
The SRY gene is found only in tissues of the developing gonads.
Answer:
The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
Explanation:
In humans, there are two sex chromosomes namely: X and Y chromosomes. The Y chromosome contains a gene called sex-determining region gene or SRY gene. The SRY gene undergoes genetic expression to produce SRY proteins, which is responsible for the development of male sexual characteristics (testes) in humans.
The SRY protein achieves this by binding to a specific region on the DNA of reproductive tissues and regulates the expression of certain genes i.e. the SRY protein acts as a transcription factor. These regulation causes male fetuses to develop testes and inhibits the development of female sexual characteristics like uterus etc.
The answer option which provides the correct information about cell signaling that supports the claim is: A. The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
A cell is the fundamental (basic) structural, functional and smallest unit of life, that is found in any living organism.
Cell signaling can be defined as a fundamental process through which specific information (signals) are transmitted from the surface of a cell to the cytosol and finally to the nucleus, thereby, causing a change in the gene expression of a living organism.
Basically, cell signaling is an ability of a living cell to do the following from and within its environment:
Process specific information (signal).Transmit specific information (signal).Receive specific information (signal).In Science, the four (4) main stages of cell signaling include:
1. Signal transmission.
2. Cell reception.
3. Signal transduction.
4. Cellular response.
In this context, cell signaling is described by the SRY gene (sex-determining region gene) produces a protein that binds to specific regions of deoxyribonucleic acid (DNA) in certain tissues, which affects the development of these tissues.

How have you heard the word metabolism used in daily conversation? How does this usage differ from the actual definition of metabolism?
Answer:
Metabolism - the chemical process within a living organism in order to maintain life
Explanation:
The common use it 'my metabolism is really slow/fast', usually heard in fitness and diet communities. The biggest difference is that, while metabolism does deal with the burning of energy from food, it really covers the processes using all materials such as water, food, nutrients, and oxygen in the cells to produce the body's energy.
Answer: Metabolism is often used in ads for exercise products or diet pills, which claim that they will boost metabolism to help people lose weight. In this context, metabolism is used only to describe weight loss or gain. This interpretation differs greatly from the actual definition of metabolism, which describes all the chemical reactions that occur within a cell.

Explain how water behaves in this reaction. Which definition of acids and bases would you apply? Upper subscript 2 upper C upper O subscript 3 plus upper H subscript 2 upper O right arrow upper H upper C upper O subscript 3 superscript minus plus upper H subscript 3 upper O superscript plus.
Answer:
Brownstead- Lowry base
Explanation:
A Brownstead- Lowry base accepts protons. If we look at this reaction, the water molecule accepted a proton to form its conjugate acid H3O^+.
Hence, in this particular instance, water behaved as a Brownstead- Lowry base in accordance with the definition of a Brownstead- Lowry bases.
Answer:
the correct answer is:
Explanation:
Water behaves as a base in this reaction.
The Bronsted-Lowry definition is applied because the reaction involves the transfer of H+ from one reactant to the other.
A Bronsted-Lowry base is defined as a substance that accepts a proton.
Because water gains a proton to form H3O+ in this particular reaction, it acts as a base.
