In mammals,  is aneuploidy of the x chromosome more often viable than aneuploidy of the autosomes is only one X chromosome remains fully functional in mammalian cells.

Many or all genes on additional X chromosomes are silenced early during development.

Aneuploidy is the condition in which the chromosomes and the number of it are missing that is either one chromosome can be missed or more than one which can lead to abnormalities in the body and malfunctioning in the expression of characters and can also lead to any chromosome number that is not the exact multiple of haploid number which in humans is 23 and its paired form has 46 chromosomes so whenever there is a loss in one chromosomes or addition of one chromosome it can lead to different syndromes like down syndrome, knilfeltners syndrome, turners syndrome and many more and it can be the main cause of miscarriages during pregnancy as well and in mammals aneuploidy of x chromosome is more viable because only one X chromosome remains fully functional in mammalian cells.

Many or all genes on additional X chromosomes are silenced early during development. In females there are two x chromosomes so even the other is silenced the other one is functional and in the same way in males the x chromosomes remains functional that is why aneuploidy affects are seen on x chromosomes.

Three reasons to use higher percentage of Nguni cattle breeds-

Nguni cattle can withstand both extremes of heat and cold since they are light and heat tolerant. They have good resistance to internal and external parasites as well as built-in immunity to diseases transmitted by ticks. They are versatile and robust. Cows will produce 10 or more calves because of their early maturity, fertility, ease of calving, and longevity. The cows wean calves who weigh 45–50% of their body mass with remarkable efficiency. Calves grow at a rate of about 0.70 kg per day until weaning, when their average birth weight is 22.5 kg and they wean at a weight of about 175 kg.

Due to their low birth mass, small uterus, and sloping rumps, Nguni cattle are less prone to dystocia.

The adaptation to the reduced size of the liver leads to (C) compensatory hyperplasia of the remaining liver cells since the patient is found to have liver disease, resulting in the removal of a lobe of his liver.

According to the medical definition of hyperplasia, this is a particular kind of biological reaction to stress. It involves a rise in cell division, which leads to an increase in the number of cells. Organs get significantly larger as a result of cell hyperplasia.

Compensatory Hyperplasia is the proliferation of cells while they retain their differentiated form and function, and it is a hyperplasia that develops in reaction to change that occurs in the body. Hepatocyte regeneration in a damaged liver is a famous illustration. The result in the adaptation to the reduced size of the liver is Compensatory Hyperplasia.

When you get a scratch, the cells in your body will multiply until  they reach the cells gathering at the other side of the wound.

A wound is a cut that occurs on the body. When the  scratch or the wound occurs, the skin cells that are around that area are destroyed. When this occurs, the person would feel pain as the blood vessels in that area become affected and the individual begins to bleed. The bleeding that the individual experiences is in proportion to the extent of the wound that the individual has.

Having said this, we know that the cells are affected when there is a scratch on the body. The scratch depends on the impact of the object that caused the injury in the body.

Immediately the scratch occurs, the cells that are around the affected area begins to multiply. The multiplication of the cells is in order to cover the area and cause the wound to heal.

Thus, when you get a scratch, the cells in your body will multiply until  they reach the cells gathering at the other side of the wound.

Functions of neurons supported by glial cells, which provide support and also help increase action potential, hence option c is correct.

Neurons are the basic functional units of the nervous system, and they create electrical impulses referred to as action potentials, which allow them to transmit data swiftly over large distances.

Glia is also essential for nervous system function, although they primarily serve to support neurons. Despite the complex nature of the nervous system, the nervous system consists of only two main types of nerve cells: neurons and glial cells.

Glial cells clearly provide "support" both for cells such as neurons and structures such as blood vessels, they can also function to increase action potential conduction.

Therefore glia provides support to the function of neurons and helps to generate an action potential, hence option c is correct.

A cell with a certain salt concentration is immersed in a solution. The cell does not shrink or swell. The solution is thus said to be isotonic to the cell.

A cell in an isotonic solution is in harmony with its surroundings, which means that the concentrations of solutes within and outside are comparable (iso means equal in Latin). Because there is no concentration gradient in this state, hence there is no substantial movement of water in or out.

A solution outside a cell is said to be hypotonic if it contains a lower solute concentration than the cytoplasm. Water diffuses into cell as a result of osmotic pressure, and the cell frequently appears turgid, meaning bloated.

Hypotonic fluid has less fluid, carbohydrates, plus salt than blood. Hypertonic fluid contains more fluid, carbohydrates, and salt then blood. Isotonic fluid, carbohydrates, and salt concentrations are similar in blood.
