Oligosaccharides are carbohydrates that consist of a few (typically 3-10) monosaccharide units (simple sugars) linked together by glycosidic bonds.

However, they are not necessarily composed of only glucose molecules; they can be made up of a combination of different monosaccharides such as glucose, fructose, galactose, etc.

Oligosaccharides can be found in many biological systems, including in glycoproteins and glycolipids in the cell membrane, where they play important roles in cellular recognition and signaling. Some oligosaccharides are also used as prebiotics in the human diet, as they are not digested in the small intestine and can be selectively fermented by beneficial gut bacteria.

In this scenario, the abiotic factors influencing the changes in the American prairie ecosystem are temperature and rainfall.

An increase in temperature can cause stress on certain plant species, like shrubs and flowering plants, making it difficult for them to survive. Meanwhile, a decrease in rainfall can lead to drought-like conditions, which further exacerbate the challenges faced by these plants.

Cacti, on the other hand, are well-adapted to survive in arid environments with high temperatures and low rainfall. They have specialized structures and mechanisms, such as shallow roots and water storage in their stems, that allow them to efficiently capture and conserve water.

As a result, if the abiotic factors in the prairie continue to shift towards higher temperatures and lower rainfall, cacti may outcompete the less-adapted shrubs and flowering plants, leading to a change in the overall composition of the ecosystem.

Carbohydrate metabolic pathways play a critical role in regulating blood sugar levels in the body. When carbohydrates are consumed, they are broken down into glucose, which enters the bloodstream and raises blood sugar levels.

In response, the pancreas secretes the hormone insulin, which triggers cells in the liver, muscles, and adipose tissue to take up glucose from the bloodstream and use it for energy or store it as glycogen or fat. This process lowers blood sugar levels.

Conversely, when blood sugar levels are low, the pancreas secretes the hormone glucagon, which stimulates the liver to break down glycogen and release glucose into the bloodstream. This process raises blood sugar levels.

Additionally, other hormones such as cortisol and adrenaline can also affect blood sugar levels by stimulating the breakdown of glycogen in the liver and releasing glucose into the bloodstream.

Overall, the regulation of blood sugar levels through carbohydrate metabolic pathways is crucial for maintaining normal physiological function and preventing the negative consequences of high or low blood sugar levels.

A delta is a deposit of soil and sand at the mouth of a river or stream.

Here, correct option is B.

It is formed when the river's current slows down as it enters a larger body of water, such as an ocean or lake. The sediment carried by the river is then deposited at the mouth, creating the fan-shaped delta. Deltas are usually found in areas where the river mouth is shallow and the current is not strong enough to carry the sediment further.

The sediment is then deposited in layers, with the coarser particles forming the base of the delta and the finer particles forming the upper layers. The delta is then subject to erosion, as the river's current carries away the sediment. This creates a distinct, fan-shaped feature with the river at its center.

Therefore, correct option is B.

In humans, the X and Y chromosomes determine an individual's sex. Females have two X chromosomes while males have one X and one Y chromosome.

Many genes responsible for various traits are located on the X chromosome. When a male inherits a recessive allele on the X chromosome, he will express the phenotype because he only has one copy of the X chromosome.

In contrast, females have two copies of the X chromosome, so they can be carriers of the recessive allele without expressing the phenotype. However, in rare cases, females can express X-linked recessive traits if they inherit two copies of the recessive allele or if they have a mutation that inactivates one of their X chromosomes.

Therefore, recessive X-linked phenotypes are more commonly seen in males because they only have one X chromosome, and thus, are more likely to express the phenotype.
