A species of mouse which was once killed by a certain disease is now resistant to the disease because some individual mice that were resistant to the disease survived and reproduced offspring. Those that weren't resistant died. Thus, the correct option is D.

Resistant genes is the gene which contains the information for the production of a protein that makes an antibiotic ineffective on that organism and hence confers resistance against that antibiotic to a pathogen.

The transfer of resistant genes can occur in organisms. Acquired resistance from the parents can occur through horizontal transfer of genes between the bacterial species, or by vertical transmission that can occur between mother and offspring at birth and during lactation period, or spontaneously due to the exposure to an antibiotic. These genes help the organism to survive in the antibiotic medium and produce offspring.

Therefore, the correct option is D.

The friend is nearsighted and a concave lens would best correct the problem. A nearsighted person has difficulty seeing objects at a distance, but they can see objects that are closer to them.

On the other hand, a farsighted person has difficulty seeing objects that are close to them, but they can see objects that are far away. A concave lens is a diverging lens that is thin at the center and thick at the edges. The concave lens is used to correct nearsightedness or myopia. It is designed to help reduce the focusing power of the lens in the eye.

By reducing the focusing power of the lens in the eye, the concave lens helps to improve the clarity of distant vision. Impaired anatomical structures that could lead to the need for glasses include: The cornea: If the cornea is too curved or not curved enough, it can cause vision problems. The lens: If the lens is too curved or not curved enough, it can cause vision problems. The eyeball: If the eyeball is too long or too short, it can cause vision problems.

A small mass of masticated food, commonly known as a bolus, is a crucial stage in the process of digestion.

After thorough chewing, the food is broken down into smaller particles, mixed with saliva, and forms a cohesive mass ready for swallowing. The bolus, consisting of a combination of food particles and saliva, is propelled by the tongue towards the back of the mouth.

As it reaches the throat, the swallowing reflex is triggered, and the bolus enters the esophagus, eventually making its way to the stomach. Once in the stomach, the digestive process continues, breaking down the bolus further into nutrients that can be absorbed by the body.

Thus, the bolus serves as a conduit for the transport and processing of food during digestion.

By adding more plants to the pond, Joann increased the rate of consumption of the excess nitrates. It would also replenish the dissolved oxygen in the water.

Fish food is rich in nitrates and phosphates. So by overfeeding, Joann increased the concentration of the nitrates and phosphates in the pond water, making it ideal for algal overgrowth.

Algae uses these nitrates and phosphates to break down the organic substances in the pond water consuming more and more dissolved oxygen. The amount of oxygen that is dissolved in the water, or the amount of oxygen that is available to living aquatic organisms, is measured by the term "dissolved oxygen" (DO).

This might suffocate the fish by creating oxygen scarcity, which would lead to their death.

Hence by adding more plants, Joann can ensure the excess nitrates added would be consumed by the new plant, limiting the nutritional supply of the algae.

Also, the potential threat of dissolved oxygen scarcity would be eliminated as the new plants would add to the dissolved oxygen content of the pond.

The movement of particles that would be most affected by a disorder causing damage to carrier proteins is active transport.

Active transport is a cellular process that requires the use of energy to move particles across a cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. Carrier proteins play a crucial role in active transport by facilitating the movement of specific molecules or ions across the cell membrane. These proteins bind to the particles being transported and undergo conformational changes that allow them to move the particles across the membrane.

If there is damage to the carrier proteins due to a disorder, their ability to bind to and transport particles may be compromised. This impairment can disrupt the active transport process, leading to a decrease or complete loss of the movement of particles against their concentration gradient. Consequently, the normal cellular functions that rely on active transport, such as nutrient uptake, ion regulation, and maintenance of cellular homeostasis, would be significantly affected.
