Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, and small and large fish will be common is a type of natural selection that is acting on the given population. So, it's B.

An ecosystem may be defined as any place or area where the members of different species or communities live together and interact with one another for the purpose of food, shelter, and space.

As predators are only able to attack the moderate-sized fishes, so the population of moderate-sized fishes may decline in the aquatic ecosystem, while extremely short and large fishes are able to maintain their population at the same pace.

Therefore, the correct option for this question is B.

The process that destroys all microbial life including spores is called Sterilization.

The foundational elements of hospital infection control procedures are sterilization and disinfection. Numerous hospitals carry out various surgical operations every day. Numerous invasive treatments are carried out in various healthcare facilities.

The risk of introducing infections into the patient's body is enhanced when a medical device or surgical instrument comes into touch with the sterile tissue or mucous membrane of the patient during the various processes.

Additionally, there is a potential that an infection will spread from one patient to another, from a patient to a member of the medical staff and vice versa, or from the environment to the patient through improperly sanitized or disinfected equipment.

Thus, The process that destroys all microbial life including spores is called Sterilization.

Because gustatory receptors have separate receptor cells and sensory neurons, there is synaptic delay in gustatory receptors that is not found in olfactory receptors.

Gustatory receptors Taste receptors are a diverse group of seven-transmembrane (non-GPCR) chemoreceptors expressed in receptor neurons of taste sensilla. They detect flavors (non-volatile compounds) by contact chemical sensing. Taste receptors, or tastants, are a class of cellular receptors that facilitate taste. When food or other substances enter the mouth, molecules interact with saliva and attach themselves to taste receptors in the oral cavity and elsewhere.The molecules that evoke the sensation of taste are called "gustatory receptors" and present in the papillae and used to sense taste. Olfactory receptors are present in the olfactory epithelium of the nasal cavity. They are used for various odor detection. Sensory signals are sent from these receptors to the brain via sensory nerves.

Answer: Some of the components in tobacco smoke include:

Nicotine (the addictive drug that produces the effects in the brain that people are looking for)

Hydrogen cyanide.

Formaldehyde.

Lead.

Arsenic.

Ammonia.

Radioactive elements, such as polonium-210

Benzene.

Explanation: Highly damaging components of tobacco smoke include:

tar – is the word for the solid particles suspended in tobacco smoke. The particles contain chemicals, including cancer-causing substances (carcinogens). Tar is sticky and brown, and stains teeth, fingernails and lung tissue

carbon monoxide – is a poisonous gas. It is odourless and colourless and, in large doses, quickly causes death because it takes the place of oxygen in the blood. In people who smoke, the carbon monoxide in their blood makes it harder for oxygen to get to their organs and muscles

oxidizing chemicals – are highly reactive chemicals that can damage the heart muscles and blood vessels of people who smoke. They react with cholesterol, leading to the build-up of fatty material on artery walls. Their actions lead to heart disease, stroke and blood vessel disease

metals – tobacco smoke contains several metals that cause cancer, including arsenic, beryllium, cadmium, chromium, cobalt, lead and nickel

radioactive compounds – tobacco smoke contains radioactive compounds that are known to be carcinogenic.

The effects of tobacco smoke on the body include:

raised blood pressure and heart rate

constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature

less oxygen carried by the blood during exercise

‘stickier’ blood, which is more prone to clotting

damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)

reduced blood flow to extremities (fingers and toes)

increased risk of stroke and heart attack due to blockages of the blood supply.

Natural Selection is an evolutionary force that acts at the phenotypic and genetic level. At the genetic level, selection decreases the genetic diversity in the population.

Natural selection is a process that results in the survival and reproduction of the fittest organisms. This theory was introduced by Charles Darwin. Natural selection operates at both the genetic and phenotypic levels. At the genetic level, selection decreases the genetic diversity in the population.

Genetic diversity refers to the total genetic information available in a population. The more the genetic diversity, the greater the number of available options. Genetic diversity plays a vital role in the survival of a population in the face of environmental challenges.At the genetic level, natural selection acts by favoring some genes over others. Selection increases the frequency of beneficial genes that improve the fitness of the organisms. Selection, on the other hand, decreases the frequency of harmful genes that reduce the fitness of the organisms. This, in turn, leads to a decrease in the genetic diversity of the population. Hence, at the genetic level, selection decreases the genetic diversity .Phenotypic level refers to the physical expression of genes.

species A and B in the table should have much more phospholipid, in the form of bilayers, to increase surface area for metabolic reactions.

Phospholipids are compound lipids made of alcohol, fatty acids, nitrogen base, and phosphoric acids. The cell membrane is primarily made up of these complex lipids, which also give the membranes their fluidity. These phospholipids constitute the interior of the bilayer and have a hydrophilic head and a hydrophobic tail in cell membranes.

Two varieties of phospholipids exist. they are as follows,

Glycerophospholipids :

They are the main phospholipid kinds found in biological membranes. Glycerol-based phospholipids make up this substance.

Answer:

Explanation:

In an overlap-layout-consensus, some of the ways to ensure that assemble repeats are to adjust the read length of the genome and using an overlap graph.

In overlap-layout-consensus (OLC) graph assembly of a genome, one way to accurately assemble repeats is by adjusting the read length to span the repetitive regions of the genome. This helps correctly resolve these regions and come very close to the ideal of a complete, continuous genome.

Arachne, a well-known overlap-layout-consensus assembler, makes use of k = 241. An overlap graph, pre-calculated by pair-wise sequence alignments, shows the sequencing reads as nodes and their overlaps as edges in the OLC method. Potential contigs in the graph can be converted to sequence by following the paths through the graph.

The statements which accurately support the argument that procreation  is advantageous over propagation in many species are given below:

Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.

Due to the involvement of two parents, procreation increases the genetic diversity among organisms.

In procreation, clutch size is low but parental care is high. It means that this type of reproduction does not produce a large number of offspring.

The plasma membrane cannot regulate simple diffusion, rather the movement of these substances is dependent only upon concentration gradients.

Simple diffusion is a passive process in which molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached. The plasma membrane does not control this process, but it does provide a barrier that allows certain molecules to pass through.

The movement of substances through the plasma membrane via simple diffusion is solely influenced by the concentration gradient, which is the difference in concentration between the inside and outside of the cell.

This means that substances will naturally move from areas of higher concentration to areas of lower concentration until the concentration is equal on both sides of the membrane.
