Answer:

Catenation:

The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.

Formation of multiple bonds:

Carbon atoms are capable of forming multiple bonds with other carbon atoms.

Hydrocarbons:

All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.

isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.

Answer:

Answer:

Embryonic stem cells are more useful than the adults stem cells because;

* Embryonic stem cells have the ability to create any cell type in the human body while, the adults stem cells are more specialized( they generally make cells only from their tissue of origin).

They have the capacity to divide into additional stem cells or any kind of body cell.

Embryonic stem cells can develop into any type of human cell, whereas adult stem cells are more specialized and typically can only produce cells from the tissue from which they originated.

Additionally, it is simple to produce embryonic stem cells in a lab setting. There is always the option to manufacture more cells as needed because the cells can be developed through cultures.

Since embryonic stem cells are pluripotent, they are more adaptable in scientific experiments than adult stem cells. Finding novel treatments for ailments, wounds, and organ failure is one of the possible advantages of studying embryos.

Therefore, Embryonic stem cells are more useful than the adults stem cells.

Answer:

The backwards rotation makes Venus the only planet in the solar system where the sidereal day is actually longer than the solar one. The sun returns to it highest point in the sky before the planet has completed one rotation. Combining all this together leaves Venus with a solar day that takes 117 Earth-days.

Answer:

lungs

Explanation:

lungs

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

The lungs exchange gases

Answer:

1. Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.

2.The SmartPill is an ingested, wireless device for measuring the health of the digestive system. As it passes through the digestive tract, the capsule transmits data to a receiver, which is later returned to the doctor and the information downloaded onto a laptop computer.

3. When its not working many of the uncomfortable reactions such as an upset stomach, allergy-like symptoms or irritability are actually signs that the enzymes are working. The body is cleaning itself out and the healing process is starting.

4.One of the main reasons for reduced output of digestive enzymes is poor exocrine pancreatic function. The causes of Exocrine Pancreatic Insufficiency (EPI) are very diverse ranging from: Problems with the endocrine part of the pancreas such as insulin dysregulation from diet high in refined carbohydrates and diabetes.

Explanation:

Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet.

Explanation:

Plants, through photosynthesis, and soils sequester roughly a third of carbon dioxide emissions released into the atmosphere each decade from the burning of fossil fuels. During photosynthesis, plants open tiny pores on their leaf surfaces to suck carbon dioxide from the air and produce their own food.

Answer:

evolution

Explanation:

adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

Deductive reasoning is a sort of logical reasoning that starts with a broad concept and comes to a specific conclusion. It is also known as top-down thinking or moving from the general to the specific. Here the blank will be logical approach.

Deductive reasoning is a type of deduction that is used in both science and life in general.

It takes place when two true statements, or premises, are combined to form a conclusion.

A is equal to B, for example. B is also the same as C. Using deductive reasoning, one can conclude A is equal to C given those two statements.

It is a type of logical reasoning that begins with a broad concept and progresses to a specific conclusion.

Thus, deductive reasoning is a logical approach.

Answer:

A zygote is a fertilized ovum. The germ cells undergo meiosis to reach a haploid state (n) as part of spermatogenesis and oogenesis. The sperm and the unfertilized ovum reinstates a chromosome set in zygote in a diploid state (2n).

After fusing with the sperm, the second stage of meiosis takes place for separation of chromatids. Post-fertilization, mitosis of the zygote is initiated which develops into a mature offspring exhibiting characteristics of its parent.

Explanation:

The zygote stage development occurs in the first week of fertilization. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual.

Answer:

Zygote is a diploid cell resulting from the fusion of two haploid gametes

it forms when a sperm penetrates the outer surface of an egg.

Answer:

Developing nanotechnology would result in a reduction of mineral use since only minute amounts of minerals are required.

Minerals refers the elemental form of elements found in the earth's crust either in the free or combined state with other elements.

Mining of minerals refers to the process of extracting minerals from the earth.

Nanotechnology would results in the use of minerals as it requires only very minute amount of these minerals in its processes.

Therefore, developing nanotechnology would result in a reduction of mineral use.

Bicarbonate ions present in body performs a variety of functions, in blood it carries carbon dioxide. Its other functions include keeping the balance of acids and bases in the body. It acts as a buffer.

Buffer is a type of solution that resists pH change either by the addition of acid or base.

Bicarbonate is a base, which the body requires to keep a normal acid-base (pH) balance.

This balance prevents the body from having too much acid means maintaining buffer. The lungs and kidneys helps to keep a normal blood pH by removing excess acid.

Thus, the correct option is B.
