Correct answer: C) Concentration gradient
The process of movement of a particle in a solution from the region of higher concentration to the region of lower concentration across a membrane is called as concentration gradient.
For example: If we drop a few drop of dye in a glass of water, it will diffuse along a concentration gradient, i.e, the region where dye is found in highest concentration to the region where it is in lower concentration.
It will occur until the concentration of dye become uniform in all the direction in the glass of water.
Answer: Central and Peripheral.
Explanation: The nervous system has two major divisions: central and peripheral. The central nervous system contains the brain and the spinal cord. The peripheral nervous system contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body.
Answer: Sperm
Explanation: Games are an organism's reproductive cells which in a male is his sperm
Answer:
These bands represent different confirmation of DNA
Explanation:
pGLO DNA is a plasmid DNA that is used as a vector for genetic engineering. Plasmid DNA is found in supercoiled confirmation in vivo. The double helix forms extra twists to easily fit inside the cells. During isolation of plasmid from the cell, nicks can be introduced in the DNA due to harsh isolating methods or contamination by nuclease. As a result the supercoiled confirmation is changed into circular confirmation. It is bulkier than the supercoiled form and travels more slowly. When both DNA stands get cut at the same place, the DNA gets liner confirmation. In the end, supercoiled DNA runs the fastest on gel followed by linear DNA and then the circular DNA.
