Meninges are membranes that cover and protect the brain and spinal cord. There are three layers of meninges: Dura mater (closest to the bone), Arachnoid loosely around the brain, Pia mater is closely attached to the brain and spinal cord surface

Hepatitis refers to an inflammatory condition of the liver. It’s commonly caused by a viral infection.

We know plants prepare their own food and so are known as autotrophs. With the help of photosynthesis they make food in which they produce glucose from carbon dioxide and sunlight. Also, oxygen is released by plants which is further used by humans and other animals. But Fungi lack chlorophyll and do not engage in photosynthesis.

The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. The spleen is not part of the digestive system however is connected to the blood vessels of both the stomach and the pancreas.

Gibberellin

Gibberellin, auxin, and cytokinin are the plant hormones helpful in this process when sprayed on flowers could stimulate the development of parthenocarpic fruit. It is termed as artificial parthenocarpy.

The Function of Cytokinins is plant hormones that cause increased cell division by stimulating the process of mitosis. They are made naturally by plants but have been synthesized by humans. Increased mitosis results in plant growth and the formation of shoots and buds, as well as the development of fruits and seeds.

These 46 chromosomes carry the genetic information that’s passed from parent to child through heredity. It is the very detail of this genetic material – in the DNA – that makes most people (other than identical siblings) totally unique.

Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the sex chromosomes, called the ‘X’ and ‘Y’ chromosome. This is the pair of chromosomes that are responsible for ‘sex-linked’ medical conditions that pass through some families, such as the blood disorder hemophilia, which affects mainly males. Females have a pair of X chromosomes, males have an X and Y chromosome.

Aestivation is summer sleep. Many organisms like the snails do not find it comfortable in summer. They withdraw and lead a life with reduced BMR (basic Metabolic Rate) in a state of  dormancy.
