With all multicellular organisms all the cells that are dividing do not undergo the process of passing genetic information. . Basically all the cells are passing out the genetic information except the RBC and the cornified cells.  

It is the information that is passing to the genomic interpretation of a living organism what to code or what not to especially for the protein.

All the cells contain the genetic information even the cells which undergo differentiation are responsible for passing out the property of an assigned function contain the nuclear DNA as well.

RBC cells are the cells which do not contain DNA and the genetic information is not stored in these cells thus these are the cells which do not have the property as discussed in the question.

Answer:

Signal transduction pathways allow different types of cells to respond differently to the same signal molecule. Signal transduction pathways convert a signal on a cell's surface to a specific cellular response.

The targets of such signaling pathways frequently include transcription factors that function to regulate gene expression. Intracellular signaling pathways thus connect the cell surface to the nucleus, leading to changes in gene expression in response to extracellular stimuli.

Answer: number 3

Explanation:

Diffusion is the process by which gases move from an area of high pressure to low pressure. This is during internal and external respiration when gas is exchanged between the alveoli and lung capillaries. It is the simple movement of gases, without the need of any energy or endeavor by the body, between the alveoli and the capillaries in the lungs. Once in the lungs, the air travels over the bronchioles where it reaches the alveoli. From there, the oxygen from the air you breathe enters your blood in nearby blood vessels.

In single-celled organisms, diffusion across the cell membrane is enough for conveying oxygen to the cell. In order to be a beneficial means of providing oxygen to the cell, the rate of oxygen uptake must meet the rate of diffusion across the membrane.

Sea ice in the summer is vanishing The amount of summer Arctic sea ice is decreasing by 13% every decade and becomes younger and thinner.

The majority of the Arctic Circle is made up of ocean, which used to be completely or partially frozen. Although seasonal ice melts sooner in the year and forms later, permanent sea ice is steadily diminishing. More open water is a result of this. But although water is darker and absorbs heat from the sun, ice is brilliant and reflects heat from the sun.

Polar bears must swim farther between large ice floes to get food as a result of the melting of the ice, and many of them perish. In the western Arctic, the depth of snow on sea ice has decreased by more than 33% over the past 30 years.

One environmental factor that could influence natural selection and decrease genetic diversity is habitat destruction or fragmentation.

When natural habitats are destroyed or fragmented due to human activities such as deforestation, mining, or urbanization, it can significantly alter the environmental conditions that organisms depend on for survival. This can lead to the loss of biodiversity and the homogenization of the gene pool within a population.

As habitats are destroyed or fragmented, species are forced to adapt to new environmental conditions or migrate to other areas. This can create selective pressures that favor certain traits over others, leading to the evolution of specialized adaptations that may not be present in other populations. Over time, this can lead to reduced genetic diversity within a population and even the loss of unique genetic variants that were once present.

Explanation:

Photosynthesis involves Light-dependent reactions, which are the noncyclic pathway, and the light-independent reactions, known as Calvin cycle. The sequence of events is described below.

NOTE: Since I could not find the complete question, I will provide a complete explanation of how photosynthesis occurs, so you will be able to arrange the events in your statement in the correct order.

Photosynthesis involves two stages: light-dependent and light-independent reactions.

LIGHT-DEPENDENT REACTION

It occurs in the thylakoids of chloroplasts. Involves the noncyclic pathway which is a flow of electrons along a chain located in the thylakoid membrane.

Photosynthetic pigments are in charge of light absorption. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain.

During these reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.

LIGHT-INDEPENDENT REACTION

Light-independent reaction is known as the Calvin cycle, and it takes place in the stroma.

During the Calvin cycle, sugars or carbohydrates are synthesized.

When carbon dioxide, CO₂, enters the leaves through stomas, it diffuses to the chloroplast stroma.

Carbon atoms fixate, meaning that they incorporate into organic molecules. These molecules are used to produce 3-C sugars.

The whole process is impulsed by ATP and NADPH coming from light-dependent reactions.

SEQUENCE OF EVENTS

⇒ THYLAKOID MEMBRANE: The steps of light-dependent reactions are the followings,

1) Luminous energy is trapped by chlorophyll in Photosystem II.

2) When the pigment molecules absorb light, electrons provided by water molecules get to a higher energy level.

3) The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.

4) When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.

5) The absorbed luminous energy moves the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.

6) When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.

7) When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.

8) The released energy is used to produce ATP molecules.

9) Hydrogen ions go back from the stroma to the thylakoid compartment.

⇒ STROMA: The steps of light-independent reactions are the followings,

1) During the carbon fixation phase, a CO₂ molecule combinates with a ribulose-1,5-bisphosphate (5-C molecule) to form 6-C molecules, which will divide into two 3-phosphoglycerate molecules, 3-PGA (3-C molecules).

    CO₂ + ribulose-1,5-bisphosphate ⟶  6-C molecule ⟶ 2  3-PGA

2) During the reduction phase, ATP and NADPH are used to produce the sugar molecule glyceraldehyde-3-phosphate (G3P) from 3-PGA molecules.

NADPH donates its electrons to turn 3-PGA into glyceraldehyde 3-phosphate, G3P.

                  3-PGA + ATP + NADPH  ⟶ G3P + ADP + NADP⁺

3) During the regeneration phase,

When three CO₂ enter the cycle, 6 G3P are produced. One of them leaves the cycle, and the remaining five are recycled and generate three RuBP.

⇒ CYTOSOL

1) Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose.

2) These two molecules are the monosaccharides that form sucrose.

3) Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

Answer: The main purposes of mitosis are  Organism growth and tissue repair and maintenance.

Explanation: MITOSIS is the step of cell division in cell cycle. Cell cycle contains G1 S G2 and M phase. During mitosis  a cell replicates its chromosome and segregates them to produce two identical daughter nuclei, which after undergoing cytokinesis produces two identical daughter cells. mitosis is often called as equational division.

Mitosis do not control metabolism nor it synthesize energy.

MITOSIS produces two identical daughter cells which are identical to their parents, so it cannot cause genetic diversity.

Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.

Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.

Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.

Due to generic factors, some people need to limit their exposure to pollen because it aggravates their respiratory systems.

What is Pathogens?

Pathogens are microorganisms, such as bacteria, viruses, fungi, and parasites, that cause diseases in humans, animals, and plants. They are capable of infecting the body and causing illness by invading host cells, tissues, and organs, and disrupting normal physiological processes.

"Generic factors" likely refers to genetic factors, which are inherited traits that can increase a person's susceptibility to certain health conditions or reactions. In the case of pollen allergies, genetic factors can play a role in determining whether a person is more likely to have an allergic reaction to pollen or not. Allergies are caused by an overreaction of the immune system to harmless substances, and this response can be influenced by genetic factors.
