The statement which is not true of the purpose of the alcohol in Gram staining is as follows:

Thus, the correct option is A.

Gram staining may be defined as a methodology that is utilized for the classification of bacterial species such as gram-positive and gram-negative.

In gram staining, ethyl alcohol or acetone is used as a decolorizer that dehydrates the peptidoglycan layer. It involves the shrinkage or tightening of the cell wall.

In this process, the large crystal violet-iodine complex is not able to puncture this tightened layer of peptidoglycan.  

Therefore, the correct option for this question is A.

Answer:

The density of a liquid is shown by the object sinking or floating. Therfore, using this information if the object sinks then the object is more dense than the object that floats. When it comes to the density of liquids if the liquid sits on top of the water and does not mix, the liquid is less dense than water. If the liquid sinks into the water and the water sits on top, the liquid is more dense than the water.

Explanation:

The advantage of selective breeding is​ the ability to produce offspring with more desirable traits. Therefore, option A is correct.

Choosing parents with specific traits to breed with one another in order to generate kids with more desired traits is known as selective breeding. For thousands of years, humans have carefully bred a variety of animals and plants, including crop species that produce more.

Through artificial selection, several fruits and vegetables have been enhanced or even created. For instance, selective breeding was used to create broccoli, cauliflower, and cabbage from the wild mustard plant.

offspring can be produced with more desirable characteristics by selective breeding. Therefore, option A is correct.

Answer: Male

Explanation:

The pelvis is narrow in males, the pubis arch is 90 degrees in angle. It is broad in case of females to support pregnancy and child birth. Also the pubis arch is more than 90 degrees in angle. An occipital protuberance is a region that connects the head to the neck and it is generally larger in males than in female. In males the forehead is sloping in the cranium whereas that in females it is vertical and flat.

Hence, the skeleton have the features that can be indicated towards the features of a male.

a. low hemoglobin levels despite high elevation in Tibetan populations over generations.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

A suggested evidence of natural selection at work in humans is the observation of low hemoglobin levels despite high elevation in Tibetan populations over generations. This is as a result of a low level of oxygen in the blood of a living organism such as humans.

Answer:

Humans have breached this cycle by digging up fossil fuels and burning them, leading to carbon dioxide building up in the atmosphere faster than natural systems can soak it up. This has led to a net increase in greenhouse gases in the atmosphere, causing the planet to heat up.

Amino Acid: lipid: Insulation

Explanation:

Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.

When a parent cell splits to create two identical daughter cells, the process of the nuclear division known as mitosis takes place in eukaryotic cells.

What is meant by mitosis?

DNA, a molecule found on chromosomes, is the genetic information carrier. They are linearly arranged genes that are present in couples in the cell's nucleus. Genes also are arranged in pairs, and each pair produces a coding that results in the production of a distinct protein.

Mitosis is a sort of cell division that makes sure each new daughter cell formed when a cell splits possess the same genomic structure.

Two cells referred to known as daughter cells are created during mitosis. Any newly formed daughter cells must have genetic material that is similar to that of the parent cell, and the number of chromosomes must stay constant.

Therefore two identical daughter cells are produced as a result of mitosis.
