In which type of human cell(s) would 46 chromosomes be located? Select all that apply.A. diploidB. eggC. somaticD. gameteE. sper
Marrrta [24]

Answer:

A. diploid and C. somatic

Explanation:

Humans are diploid organisms and have 23 pair of chromosomes i.e. in total humans have 46 chromosomes.

There are 2 types of cells in humans (1) somatic cells and (2) germ cells.

Somatic cells are normal body cells which are diploid and have all 23 pairs of chromosomes. But, germ cells are special type of cells which are produced by gonads (sex organs). Germ cells are also known as gametes. In females, ovary is the sex organ which produces germ cells named as egg cells while in males testes is the sex organ which produces germ cells named as sperms. Germ cells (egg and sperm) are haploid cells which fuse to form a zygote which is the first cell of next generation. The process of fusion of egg and sperm is known as fertilization which is responsible for restoring diploidy in the progeny which receives half the genetic material from female parent and half the genetic material from male parent.

What part of DNA determines traits?
makvit [3.9K]

Answer:

The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.

Name the quadrant(s) (RUQ, LUQ, RLQ, and LLQ) and region(s) (right hypochondriac, epigastric, left hypochondriac, right lumbar,
andreev551 [17]

Answer:Answer: 1) (a) The left lobe of the Liver is located in Left Upper Quadrant while the main part of the Liver is located in the Right Upper Quadrant.

(b) The liver is located in both the right hypochondriac region and the epigastric region

2) (a) The stomach is is located in the Left Upper Quadrant (LUQ)

(b) The stomach is majorly located in the epigastric region and the Left Hypochondriac Region.

3) (a)The Spleen is located at the Left Upper Quadrant (LUQ)

(b) The regions the Spleen are located at are the Left Hypochondriac Region, Epigastric Region and Left Lumbar

4) (a) The Gall Bladder is located at the Right Upper Quadrant

(b) The Gall Bladder is located at the Right Hypochondriac Region and the Right Lumbar Region.

5) (a)The Appendix is located in the Right Lower Quadrant

(b) The Appendix is located in the Right Iliac region.

6) (a) The Left kidney is located at the Left Upper Quadrant

(b) The left kidney cuts across the Left Hypochondriac Region, Right Lumbar and the Left Lumbar.

7) (a) The right Ovary is located at the Right Lower Quadrant

(b) The region of the right ovary is the hypogastric region.

8) (a) The Uterus is located at both the Right Lower Quadrant and Left Lower Quadrant.

(b) The Uterus is located in the hypogastric region of the abdomen.

Explanation: In medicine, the practitioners divide the lower part of the body known as the 'abdomen' with imaginary lines ( one vertical and one horizontal) to form the 'Quadrants' and (two vertical and two horizontal) the 'Regions'. The Quadrants are divided into four main parts:

1) Left Upper Quadrant (LUQ)

2) Right Upper Quadrant (RUQ)

3) Left Lower Quadrant (LLQ)

4) Right Lower Quadrant (RLQ)

The regions are divided into nine parts:

1) Left Hypochondriac Region

2) Right Hypochondriac Region

3) Epigastric Region

4) Left Lumbar Region

5) Right Lumbar Region

6) Umbilical Region

7) Right Iliac/Inguinal Region

8) Left Iliac/Inguinal Region

9) Hypogastric Region.

The abdomen is divided into regions in order to help medical practitioners and students easily understand the abdominal area of the body as well as the human anatomy. It also helps them provide preliminary diagnosis and treatment based on pain emanating from each region or quadrant.

polysaccharide protein

Enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist

Explanation:

Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
