Answer:Have you ever wondered how scientists extract DNA from an organism? All living organisms have DNA, which is short for deoxyribonucleic acid; it is basically the blueprint for everything that happens inside an organism’s cells. Overall, DNA tells an organism how to develop and function, and is so important that this complex compound is found in virtually every one of its cells. In this activity you’ll make your own DNA extraction kit from household chemicals and use it to separate DNA from strawberries.

10. Name the pigments present in plants which can absorb solar energy.
Minchanka [31]

Answer:

10. chlorophyll

11. There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

12. Nutrition is necessary for the growth of new cells and the replacement or repair of worn-out cells. Nutrition gives energy for different metabolic processes in the body. Nutrition is required to produce resistance against different diseases.

13. trypsin

14. salivary amylase

15. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.

16. Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.

17. Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

18. small intestine

19. heterotrophic

The immune response requires a team effort. How do the specific and non-specific defenses work together? EXPLAIN YOUR ANSWER.
kotegsom [21]

A non-specific immune response (also called immunity) is antigen-independent while a specific immune response is antigen-dependent. The examples of the non-specific immunity are fever, phagocytosis by macrophages, skin and mucus.  The example of the specific immune response is cytotoxic T-cells able to recognize antigens on infected cells and kill them before the infection could spread.

Compare and contrast structural and functional proteins
vova2212 [387]

The major difference between these two types of protein is that structural proteins are used as structures while functional proteins perform specific active functions in the cells.

1. Nucleotides: A phosphate group, a 5-carbon sugar, and a nitrogenous base are the three components of a nucleotide. Adenine, cytosine, guanine, and thymine are the four nitrogenous bases in DNA. Instead of thymine, uracil is found in RNA. The genetic material of all known living creatures is made up of nucleotides in a chain.

2. Genes:  A gene is a small segment of a lengthy DNA double helix molecule that consists of a linear base pair sequence. A gene is any portion of DNA that contains instructions that allow a cell to generate a specific product – usually a protein, such as an enzyme – that performs a single specified action.

3. A locus (plural loci) is a stable location on a chromosome where a certain gene or genetic marker can be found.

4.  At a genomic region, an allele is one of two or more variations of DNA sequence (a single base or a segment of nucleotides).

5.  Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.

6.  Karyotype: A karyotype is a individual's entire set of chromosomes. A laboratory-produced representation of a person's chromosomes extracted from an individual cell and arranged in numerical order is also known as a chromosomal map. A karyotype can be used to check for chromosomal number or structural problems.

8. Genotype: An organism's genotype is its genetic makeup. From embryonic development to adulthood, the genotype determines an individual's inherited potentials and limitations. In se×ually reproducing organisms, a person's genotype is made up of the whole set of genes acquired from both parents.

9. Phenotype: Physical traits are described by phenotypes. It encompasses both apparent (such as hair or eye color) and measured characteristics (like height or weight). Characteristics relevant to your development and behavior, such as personality traits, are also referred to as phenotypes.
