Which question, is it b, c or 4

Answer:

Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon. This myelination, as it is called, can greatly increase the speed of signals transmitted between neurons (known as action potentials).

Answer:

The color of a dog's fur with the genes aabb would be yellow. So, in other words, Option A is correct.

Hope this helped :D Happy holidays! :D

Epistasis is the effect or character appear due to the interaction between genes. Here, the alleles responsible for the color of dog's fur show epistasis and the progeny with (aabb) genotype will show white colored fur. Thus, the correct option is D.

Epistasis is also known as gene masking, where the expression of one gene is modified or masked or suppressed by the expression of another gene or more other genes. In this, more than one gene controls a specific character such as fur color, etc.

Epistasis is of different types such as dominant epistasis, recessive epistasis depending upon the effect of genes.

Here, the progenies with AABB genotype show black colored fur, the progeny with Aabb show brown colored fur, the progeny with genotype aaBB show yellow colored fur, and therefore, the progeny with genotype aabb i.e., both the recessive genes will show white colored dog fur.

Therefore, the correct option is D.

Answer:

nerve cell

Explanation:

it helps in the nervous parts

it comprises of neuron,dendrides and axons..

The given cell is the nerve cell, as the structure has a single cell body and dendrites that are coming out of the cell body, and it is important for the body as the function is to send information.

In animals, nerve cells are the primary cells that carry information throughout the body and are responsible for transmitting information in the form of electrical and chemical signals, and each neuron has three main parts: the cell body, dendrites, and axons, here the cell body contains the cell's nucleus and other organelles; dendrites are branching extensions of the cell body that receive signals from other neurons or sensory cells; and axons are long structure that transmit signals to other neurons.

Hence, the given cell is the nerve cell, as the structure has a single cell body and dendrites that are coming out of the cell body, and it is important for the body as the function is to send information.

Answer:

Producers are the plants that use sunlight, water, and carbon dioxide to make their own food. They are called producers because they produce sugars from CO2 which they share with the rest of the world through photosynthesis. The carbohydrates, fats, proteins etc in your diet were all originally made by green plants! All green plants need is CO2 and water to live.

Explanation:

Answer:

Sugar and oxygen

Explanation:

energy from the sun converts the carbon dioxide and water it absorbs into sugar and the byproduct of oxygen

Answer:

Large nitrogen-containing polymers found mainly in cell nuclei

Explanation:

The statement that best describes nucleic acids is that they are large nitrogen-containing polymers found mainly in cell nuclei, which is present in Option A. Nucleic acid includes both the DNA and the RNA, and in eukaryotes, these are found in the nucleus.

The nucleic acid consists of DNA and RNA, which are made up of nucleotides, each of which is composed of a sugar, either deoxyribose sugar (DNA) or ribose sugar (RNA), phosphate, and a nitrogen base. In humans and other eukaryotes, DNA and RNA are present in the nucleus. In the human cell, the DNA is double helical, with hydrogen bonds connecting the strands.

While RNA is a single chain, the majority of it does not form a double helix. Nucleic acids carry out the gene expression present in the cell.

Hence The statement that best describes nucleic acids is that they are large nitrogen-containing polymers found mainly in cell nuclei, which is present in Option A.

All bone formation is a replacement process. During development, tissues are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage, bone formation, also called ossification, process by which new bone is produced. ... Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as mineralized bone. The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres.

Explanation:

Sociologists argue that the division of the human population into two distinctive and  mutually exclusive categories, male and female, is best understood as a biological fact.

The division into these two major categories as male or female is mainly due to the biological and the physiological characteristics produced in both male and female.

Although in some cases, it may be argued that they are not mutually exclusive as there are some who have both.

Nevertheless, the above mentioned characteristics are just used to differentiate between a male and a female in humans and as well an individual self-concept of being a male or a female.

The flow of carbon between inorganic and organic sources in the environment is best description of the carbon cycle as a whole. Thus, option B is correct.

It is the process in which carbon compounds are interchanged among the biosphere.

For example the elemental form of carbon such as diamond and graphite in a combined state are mostly found as carbonates and as carbon dioxide gas.

It act as a blanket over our earth, by balancing the energy and also absorb  sun's long wave length radiation.

It also involve in plant photosynthesis, bioaccumulation of carbon occur in animal body by consuming plant material, after the death of the animal it can decomposed and carbon is released back into the atmosphere.

The carbon which is not released back will form  fossil fuels.

B: Haploid cells join to form an organism that has a complete set of chromosomes.

Explanation:

HOPE THIS HELPS!!!!

Haploid cells join to form an organism that has a complete set of chromosomes describes a process associated with meiosis.

Meiosis occurs in the primordial germ cells, which are distinct from the body's normal somatic cells and are designed for sexual reproduction. A germ cell goes through interphase, during which the entire cell, including the genetic material.

In sexually reproducing organisms, meiosis is a unique type of cell division that results in the production of gametes, such as sperm or egg cells. It involves two division rounds that produce four cells with just one copy of each chromosome.

Gametes, or sex cells, are produced during meiosis. Each of the four haploid daughter cells produced during meiosis has half the number of chromosomes as the parent cell.
