What is the difference between DNA, chromatin, and Chromosomes?

Serhud [2]3 years ago

Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.

A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.

Under a microscope, chromatids look like little dots and chromosomes are lines.

yKpoI14uk [10]

Answer:

a,c,d

Explanation:

Crossing over occcur when genetic material is exchanged between homologous chromosome this leads to formation of new genes that creates diversity.

homologous chromosome assort imdependently i.e seperate from each other leading to the formation of an entirely new gene that creates diversity.

Genetic recombination when gene recombines together to produce a unique type. It occurs between different species.

Carbon from glucose is essential for the formation of amino acids. Which process is responsible for the
insens350 [35]

The process that is responsible for the production of glucose in plants is photosynthesis.

<h3>What is photosynthesis?</h3>

Photosynthesis is a chemical process in which organic matter is formed from inorganic matter thanks to <em>sunlight</em>, this is a process given in autotrophic organisms which are <u>capable of synthesizing their own food</u> through this process.

What happens is that thanks to sunlight, molecules are formed that contain high levels of energy (ATP and NADPH), these molecules are used for the synthesis of carbohydrates that are used to feed the cell.

Therefore, we can confirm that the process that is responsible for the production of glucose in plants is photosynthesis.

Rasek [7]

Answer:

1) The main difference between Fats and Oils is that, fats are usually derived from animals, whereas oils are usually derived from plants.

Fats and oils are very important for every human body. It is mainly essential for daily dietary plan. Fats and oils are totally different from each other. In simple terms, fats are animal fats whereas oils are vegetable oils. The other difference is fats tend to be solids at room temperature; on the other hand, oils tend to be liquid at room temperature. Remember, on the daily basis the two terms can be used interchangeably because both, fats and oils contain 9 calories per grams.

2) Phospholipids are similar to triglycerides, but they do vary slightly in form and function. While triglycerides have glycerol and three fatty acids, phospholipids have glycerol, two fatty acids and a phosphate. Phosphates are molecules with charges and have oxygen and phosphorus. ... Fat cells do not store phospholipids.

3) Thoracic cavity, also called chest cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm. It contains the lungs, the middle and lower airways—the tracheobronchial tree—the heart, the vessels transporting blood between the heart and the lungs, the great arteries bringing blood from the heart out into general circulation, and the major veins into which the blood is collected for transport back to the heart. The heart is covered by a fibrous membrane sac called the pericardium that blends with the trunks of the vessels running to and from the heart. The thoracic cavity also contains the esophagus, the channel through which food is passed from the throat to the stomach.

4) An organelle (think of it as a cell's internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

5) Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. Many organs working together to accomplish a common purpose is called an organ system.

6) Absorption: The process of absorbing food in the form of nutrients into the blood stream of the body. Assimilation: The process of nutrients being absorbed by each cell of the body in the form of energy. Egestion: Secretion of waste, unwanted and excess substances from the body after food the as been digestion
