Ans. 'Reproduction.'

Skin cells are somatic cells or normal body cells that show mitotic cell division. These cells die and are lost daily, even without any damage or injury. Our body makes continuously new skin cells to replace died skin cells. Thus, the purpose of cell cycle for skin cells to replenish lost cells is reproduction.  

Thus, the correct answer is option). reproduction.

andrezito [222]

Answer:

Medical uses: The field of genetic engineering is making progress rapidly and it has helped doctor's to fight many challenging diseases. One of the medical use of genetic engineering is the production of insulin by genetic engineering and also the production of vaccines through this technique.

Agricultural uses: The field of biotechnology can change the life of farmers once it is fully known that the genetically engineered crops cannot harm the humans. One of the uses of genetic engineering in agriculture is the production of crops containing increased nutrition. For example,Golden rice which carries vitamin A in it.

Environmental uses: Genetic engineering is used to clean the Earth by producing genetically engineered microorganisms which can not only break down waste but also can degrade plastics.

When NADH passes its electrons into the Electron Transport System, NADH is chemically:
erik [133]

Answer:

Option D, oxidized

Explanation:

The NADH gets oxidised when it passes its electrons into the Electron Transport System

Oxidization is a process in which one element or compound loses its electron to other chemical element or compound thereby itself getting oxidised and reducing the other one (the one who gains the electron).

Here in the electron transport system, the NADH loses or donates its electron to the Electron Transport System thus chemically it gets oxidized.

Hence, option D is correct

Which of these is an example of part of a scientific theory?
Svetlanka [38]

The statement that is an example of part of a scientific theory statement that carbon is matter and cannot be created or destroyed (option A).

<h3>What is scientific theory?</h3>

Scientific theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed, or which sets out the laws and principles of something known or observed.

A scientific theory can be said to be an hypothesis confirmed by observation or experiment.

Therefore, the statement that is an example of part of a scientific theory statement that carbon is matter and cannot be created or destroyed because it is an established fact.

Arrange these elements of the intrinsic conduction system in the order that a depolarizing impulse travels during a normal heart
zlopas [31]

Answer:

SA Node

Inter-nodal Pathways

AV Node

AV Bundle

Bundle Branches

Purkinje Fibers

The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.
