Answer:

The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.

In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

Answer:

it should grow bigger over time

Explanation:

Answer:

Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. That causes their genes to become more common in the population over time, and it's the way species evolve to adapt to changes in their environment.

Answer:

In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).

Slomovic, S., Laufer, D., Geiger, D., & Schuster, G. (2005). Polyadenylation and degradation of human mitochondrial RNA: the prokaryotic past leaves its mark. Molecular and cellular biology, 25(15), 6427-6435.

The correct answer to this open question is the following.

These are the four points that explain the reason why the pace of the development of society is not equal everywhere.

1.- Education. Formal education is of the utmost importance in societies that are considered developed or part of the first world. On the other hand, lack of education is a major reason why people stay ignorant and progress is minimum. Governments must invest in a good public education system with opportunities for all.

2.- Infrastructure. If the country cannot cover the necessities of its citizens, it would be more difficult to develop the kind of infrastructure that allows growth for the nation. This means poor means of communication, poor road conditions, lack of trade systems, poor health services, and limited resources to create jobs in industries.

3.- Culture. People's idiosyncrasy has a lot to do with the way they think and behave. This directly impacts the way people see life, personal progress, ambitions, and aspirations.

4.- Location. Often, geographical location limits the progress and development of a country. For instance, Middle East countries have a problem accessing water resources. Or countries that have geographical features such as mountain ranges or deserts that limit communication and trade with other countries.

The pace of development of society is not the same everywhere, because geography, economy, natural resources and technological development are not the same, these being important points for the development of a society.

Social development is an important factor found in society, capable of changing its social and economic course, so that the increase in social development means an increase in human capital and in social capital itself, moreover, it means more than a quantitative issue. , but also something qualitative.

With this information, we can conclude that pace of development of society is not the same everywhere, because geography, economy, natural resources and technological development are not the same, these being important points for the development of a society.

Explanation:

The process directly responsible for root growth in plants is cell division. So, the correct option is D.

The process by which a cell divides into two or more daughter cells is called cell division. In relation to the above question, cell division is the mechanism due to which plant roots grow.

The meristematic region, which is in charge of cell division, is designated as part D in a cross-section illustration of the root tip of a plant. The meristem of the root is a unique region where cells continuously divide and differentiate into different tissues, helping the root to expand and mature.

Many tissues of the root, including the epidermis, cortex, and vascular tissue, are composed of distinct types of cells that differentiate when they divide into specialized cell types.

So, the correct option is D.

Answer:

1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat

Explanation:

RNA contains both nitrogen and phosphate hence it is the substance in tube 1.

Insulin being a protein contains sulfur hence it is the substance in tube 2.

Lysine does not hydrolyse hence it is the substance in tube 3.

Fat is hydrophobic hence it is the substance in tube 5.

Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.

Based on these data, each tube is identified as:

Hydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.

Nitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.

In RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA

Fatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.

Answer:

Explanation:

The VHL gene is a tumour suppressor gene that regulates cell growth and cell death. This gene is also located on chromosome 3. It functions to prevent rapid proliferation of cells. For a person to develop tumor both copies of the gene must be mistake or altered allowing for a loss of function that prevents its from causing degradation of HIF1α in the normal oxygen level as its it normal function. This then allows for the survival of HIF1α that promotes amgiogenesis promoting tumor development.

Answer: 1. Scientific theory

2. Scientific hypothesis

3. Scientific law

Explanation:

The scientific theory can be defined as the aspects of the natural world that are tested and proofed by the scientific methods, involving the observations, measurements and evaluation of the outcome. The scientific theory can be changed with new ideas or evidences. The first statement is a scientific theory because the microbial population may change due to the fact that how microbes interact rather than restricting to the differential reproductive success.

The scientific hypothesis can be defined as the statement that is required to be tested or verified by scientific method. It is based on presumption. The second statement is the example of scientific hypothesis because it is beginning with "if" here it is presumed that if the culture is exposed to ultraviolet radiation then reproductive success rate will be reduced.

The scientific law is based upon facts or evidences obtain after experimental trails or applying the scientific methodology. This cannot be changed with time. The third statement is the Mendel's law of dominance.

Lipids, proteins, nucleic acids, and carbohydrates are the four main types of carbon based biomolecules.

Biomolecules can be defined as the basic component of all living cell and it is the primary building blocks like Carbohydrates, Proteins, Fats, Nucleic Acids.

Carbohydrates or sugars are the primary energy source of body which are composed of polyhydroxy aldehydes or ketones formed by hydrolysis reaction; It can be monosaccharide, oligosaccharide and  polysaccharides.

Proteins are the structural unit and it express character of a gene and synthesized by translation from RNA; It is a polymers of amino acids, can be up primary, secondary, tertiary and quaternary protein.

Nucleic acids are the house of all genetic material of the cell which  are up two types namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Lipids are insoluble substance as it can not dissolve in water, soluble in only in non-polar solvents, include sterols, fat-soluble vitamins, mono-, di- or triglycerides, phospholipids, etc.
