Loss of habitat is the main reason for decreasing wildlife population in most of the places in our country.
The term "habitat loss" describes the shrinkage of the area where a single species, or a group of species, may coexist and reproduce. Human activities such as farming, urbanization, deforestation, resource extraction, fragmentation, damage, changing the seafloor, or releasing pollutants can lead to habitat loss.
Environmental changes, such as tsunamis or volcanic eruptions, as well as shifts in the climate or the level of the water, can also result in habitat loss. As a result, species ranges and interactions are changed, and biodiversity is decreased.
In simple terms, when a habitat is destroyed, the plants, animals, and other species that lived there have a lower carrying capacity, which causes population declines and increases the likelihood of extinction.
Therefore, option c is the correct option.

A special type of passive transport is the movement of water across a membrane, or osmosis.
By definition, osmosis is the diffusion of water through a selectively permeable membrane from an area of high water potential (low solute concentration) to and area of low water potential (high solute concentration). Therefore, for osmosis to occur, the membrane must be permeable to water, but impermeable to the solute, and the concentration of the solute must be different on the two sides of the membrane. Water will move from the side with lower solute concentration to the side with higher solute concentration until the concentrations are equal, or until some external force prevents further movement of water. This is a passive process, in that no energy expenditure is required for the movement of water. In an artificial system such as the one depicted in the figure below, water will attempt to move from chamber B to chamber A. Since chamber A is a rigid chamber, pressure will develop. The pressure that is just sufficient to prevent water from moving across the membrane is referred to as osmotic pressure.

This results in the formation of cells with half the number of chromosomes as the original cell, which in humans is 7 chromosomes. In meiosis II, sister chromatids separate. Two cells combine during fertilization to produce offspring with 14 chromosomes.
In meiosis I, homologous chromosomes, which are pairs of chromosomes that contain genes for the same traits, separate from each other. During fertilization, which is the process by which an egg and sperm combine to form a zygote, two cells with 7 chromosomes combine to produce an offspring with 14 chromosomes.

what would happen to the helix-3 interaction with dna if a mutation occurred that altered this adenine (as shown) to guanine?
The integrity of the interaction would decrease to the helix-3 interaction with DNA if a mutation occurred that altered this adenine to guanine. The integrity of the interaction would decrease to the helix-3 interaction with DNA if a mutation occurred that altered this adenine to guanine because one of the two hydrogen bonds would not be able to form.
If a mutation occurred that altered an Adenine to Guanine, the helix-3 interaction with DNA would be affected as follows:
1. Adenine is a purine base, while Guanine is a pyrimidine base. This means that the shape of the base in the DNA molecule would change, as purines are larger than pyrimidines.
2. This shape change would result in a decrease in the number of hydrogen bonds between the helix-3 and the DNA molecule. This is because Adenine can form two hydrogen bonds with a cytosine, while Guanine can only form three hydrogen bonds with a cytosine.
3. The decrease in hydrogen bonds would weaken the interaction between the helix-3 and the DNA molecule, reducing the stability of the DNA structure.
4. The DNA molecule would become more vulnerable to damage and mutations, as the helix-3 is an important structural component of the DNA molecule.
