Genome editing is a group of technologies that enables scientists to edit an organism's DNA. One genetic editing technology is called CRISPR-Cas9, which was developed based on a naturally occurring genome editing system in bacteria. CRISPR-Cas9 uses a cell's own machinery to edit the genetic material; scientists can add or remove genetic sequences from an organism's genome. CRISPR-Cas9 can customize an organism's DNA by replacing an existing segment with a customized sequence of DNA. In 2018, a Chinese scientist announced that he had created the world's first genome-edited babies, twin girls born in November 2018. The scientist wanted to create children who were resistant to Human Immunodeficiency Virus (HIV). The Chinese scientist used CRISPR-Cas9 to disable a gene called CCR5, which encodes a protein that enables HIV to infect cells. This announcement caused outrage in the international scientific community. While genomic editing of bacteria and viruses is commonly used in science, genetic editing of humans remains highly controversial. Why do you think the news of this new use of CRISPR-Cas9 in humans generated so much anger in the research community and in the world at large? What are the dangers of genomic editing in humans?

Answers

Answer 1

Answer:

Explanation:

It generated anger because:

1) Human gene editing is highly controversial as humans are considered the "top" organisms and any tests conducted on humans whether it be clinical trials of medicine and such need to be approved and need to be ethical.

2) We are still years behind in terms of knowledge of genomic editing on animals and its side effects, and taking this in account, performing such editing with humans is obviously going to draw controversy as we do not know enough about genomic editing.

Dangers of editing in humans:

1) Although Crispr-Cas9 is highly accurate, it is still capable of making mistakes and we are still unsure about how those mistakes can affect the whole human. After all, the editing needs to be done in embryo for it to make a pronounced effect later in life on the grown human so any mistakes could ruin the new life of this human.

Answer 2

Gene editing is a technique that is used in research areas to modify genes of organisms for improving their function and to treat diseases.

Genome editing generated anger when used on Humans because:

Genome editing or any research based on humans as a subject is considered very controversial and have always created anger even in the case of clinical trials.

Genome editing has been conducted on animals for years and the results and side effects are the reasons that the human specimens cannot be used for experimentation.

Dangers of genome editing in humans:

The accuracy rate of gene editing is still not 100% and they are chances that unintended changes can occur during editing.

These mistakes and errors can affect the human as a whole and will ruin its whole life.

The possibility of getting cancers and getting vulnerable to biological attacks makes gene editing in humans a disadvantage.

Thus, human gene editing is a controversial issue.

What could happen if a person doesn’t get the proper amount of protein in his or her diet? The impact of a diet lacking in protein would be of little consequence. Stored proteins would assist in creating new amino acids that the body needs. The body would break down existing muscle to get the amino acids it needs.

Answers

Answer:

The body would break down existing muscle to get the amino acids it needs.

Explanation:

If a person doesn’t get the proper amount of protein in his or her diet, then the body would break down existing muscle to get the amino acids it needs, which are present in the last option.

What is the function of proteins?

Proteins are made up of building blocks called amino acids; some of these amino acids can be produced by the body, while others must be obtained through the diet, so if a person does not consume enough dietary protein, their body may not have access to enough essential amino acids to build and repair tissues or produce enzymes. As a result, the body may break down muscle tissue in order to obtain the amino acids it requires, resulting in muscle wasting; the immune system may not function optimally; and so on.

Hence, the body would break down existing muscle to get the amino acids it needs, which are present in the last option.

How does the structure of epithelial tissue help it to perform its function? Its ability to conduct electrical signals allows for control and coordination of body movements. Its fibrous layers allow the tissue to be a strong yet flexible binding agent. Its contractile cells that make up the tissue allow for movement. Its tightly packed cells allow for protection against harmful substances.

Answers

Answer:

Explanation:

Epithelial tissue consists of tightly packed sheets of cells that cover surfaces—including the outside of the body—and line body cavities. For instance, the outer layer of your skin is an epithelial tissue, and so is the lining of your small intestine.

Epithelial cells are polarized, meaning that they have a top and a bottom side. The apical, top, side of an epithelial cell faces the inside of a cavity or the outside of a structure and is usually exposed to fluid or air. The basal, bottom, side faces the underlying cells. For instance, the apical sides of intestinal cells have finger-like structures that increase surface area for absorbing nutrients

The paramecium was the only unicellular organism that Stella viewed through her microscope. All the other organisms were multicellular. How was the unicellular specimen different from the multicellular organisms?

Answers

Answer:

The difference between a unicellular specimen and other multicellular organisms will be the NUMBER OF CELLS. See detailed explanation below.

Explanation:

Cells are the simplest and basic unit of life. Living organisms has been classified as unicellular or multicellular depending on the number of the cells that make them up. A unicellular organism is that which possess only one cell to carry out all its life functions. According to the question, the Paramecium is an example of unicellular organism.

On the other hand, a multicellular organism is made up of many cells that specializes to perform the different life functions of the organism. This means that a specific kind of cell carries out a specific life function, this is called Cell differentiation. Examples of multicellular organisms include plants, all eukaryotic fungi etc.

Therefore, Stella's unicellular specimen, which is the Paramecium, will be different from other multicellular organisms in the number of cells possessed by each of them. The unicellular specimen will possess just a single cell while the multicellular organisms will possess more than one cell as viewed by the microscope.

2. What is Nutrient?
3. Differentiate between macronutrient and micronutrients? Give
some examples of each type.
4. What did the law of conservation of matter say?​

Answers

Answer:

Substances that living organism obtained from food substances consumed for effective  biochemical reactions of the body are called nutrients.Theses substances are produced  in cells of living organisms,they are therefore obtained from the food substances consumed.When they  are needed in large amounts for survival of living organisms they are called Macro nutrients or essential nutrients-CHO,proteins fatty acids  are examples but in smaller amounts as micro nutrients,because they are needed for the general well being,thus living organism can survive without them-Ca,K,Zn,Mg are examples,

The law of conservation matter- Matter in any chemical reactions the total mass of the product must be equal in proportion to that of the reactants.Thus the mass in the reaction must be constant,

Biogeochemical cycles;this is also known as substances turn over,It is the exchange of elements and compounds between the living organism and their immediate environments.

Thus living  organisms obtained substances in the food chain as this is moved from one trophic levels to another.These are used for different biochemical reactions. However,they are expanded  for  different biochemical activities ,excretion,respiration,locomotion and movements and  death and decomposition where after decay,are reabsorbed by the producers for the cycle to continue.

Explanation:

1> Biogeochemical cycle has four
different name -Carbon cycle-Hydrologic cycle-Nitrogen cycle-Oxygen cycle

2> a substance that provides nourishment essential for the maintenance of life and for growth.

3> Macronutrients are those nutrients that the body needs in large amounts. These provide the body with energy (calories). Micronutrients are those nutrients that the body needs in smaller amounts.

4> Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

How does this image compare to the white blood cells you saw using Stella’s compound microscope? What are the pros and cons of using electron and compound microscopes? In your response consider cost and ease of use.

Answers

Answer:

The Resolution and  Magnify power are the major  differences between the electron microscope compare to compound microscope. This is due to the source of power for the operation,Light rays of (400-700nm) are used by the compound microscopes,while short frequencies  beam of  electrons  of(  1 nm)are used by the  Electron Microscope.

The compound microscope consists of objective lens  with short focal length.They are therefore used for magnification of tiny objects.While the   E. microscope makes use of beam of electrons(compare to light rays in  the compound microscope) with higher resolutions.The  beam of electrons are  focused by magnetic lenses to give images.

Electron microscope is cumbersome to use,it is expensive, requires a lot of expertise, and occupies large space.

Compound are less expensive with low maintenance,it  does not requires expertise;very easy to operate, and can easily be moved about.

There is low risk of radiation with compound,lower magnification,both dead and living creatures can be used.

E.microscope,has high radiation risk,higher magnification, with only dead materials.

Explanation:

White blood cells are the immune cells that protect the body. They are also known as leukocytes or leucocytes.

The compound microscope magnifies objects lesser than the electron microscope. We can see higher magnified things in the electron microscope.

Pros and cons of  electron and compound microscope

Compound microscopes are easier to move and set up because they are small and light.

Electron microscopes are heavy and higher. They are harder to set up and move.

Electron microscopes use electromagnet glasses, whereas compound microscopes use glass lenses.

Describe the process of mitosis and meiosis.​

Answers

Answer:

Mitosis:

Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.

Meiosis:

Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.

The process of dividing the pre-existing cell into two or more daughter cells is called cell division.

Mitosis

Mitosis is defined as the division of the cell in which a single cell divides to form two daughter cells, having the equal number of chromosomes as present in the mother cell. In mitosis cell division, chromosomes duplicate and equally distribute into two diploid cells. Thus as a result, all the daughter cells come to have the same number of chromosomes compared to the mother cell. It occurs in somatic or vegetative cells.

Meiosis

Meiosis is a types of cell division in which a mother cell divides into four daughter cells and each daughter cell having only the half number of chromosomes as compared to mother cell. Meiosis cell division comprises two divisions: Meiosis I and Meiosis II

The meiosis I division is also known as reduction division. This is because it involves the formation of two daughter nuclei with just half number of chromosomes as that present in the another cell. more over, in the prophase stage of meiosis, crossing over ( interchange of chromosome segments between two homologous chromosomes) takes place. This causes the variation in the off-spring and gas a role in evolution.

The meiosis II is also called equational division because the number of chromosomes remains the same in the daughter nuclei as after meiosis I. In this way, four daughter haploid nuclei formed. Then the divison of cytoplasm of the cell ( cytokinesis) takes place and all nuclei get their own cytoplasm and form four haploids.
