The group of crop plant that are vegetatively propagated is:

 

A protein is being assembled when RNA is being translated. This process goes as, by the process of transcription first DNA is is converted to mRNA. And then by the process of translation this mRNA is converted to proteins.

=> DNA ----> mRNA ----> Proteins.

A gametes are haploid cells as they have only one set of chromosomes. Meiosis is a process of cellular reproduction in which both male and female gametes are formed. During meiosis, the DNA is only replicated or copied one time.

A nutrient is a substance used by an organism to survive, grow, and reproduce. These are compounds in foods essential to life and health, providing us with energy.

There are two types of nutrients:

1. Organic Nutrients
2. Inorganic Nutrients

Carbohydrates (CHO), Lipids (fats), Proteins and Vitamins come under organic nutrients as they contain carbon. These can add fat to the body.

Minerals and Water come under inorganic nutrients as they lack in carbon. These cannot add fat to the body.

Goosebumps are caused by the contraction of the tiny muscles attached to hair follicles. These muscles are arrectores pilorum muscles.

Mitochondrial DNA analysis is best suited for Forensic science analysis.

The three types of muscle fibers are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). Slow oxidative fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue.

A dissecting aortic aneurysm occurs when the inner layers of the aorta become separated.

The number of cell layers and cell types together give rise to 6 different types of epithelial tissue.

1. Simple squamous epithelia

2. Simple cuboidal epithelia

3. Simple columnar epithelia

4. Stratified squamous epithelia

5. Stratified cuboidal epithelia

6. Stratified columnar epithelia

Stratified squamous epithelia is best suited for areas subject to friction.
