The statement is True i.e. option (a) for The backbone of a DNA or RNA strand is made of alternating and molecules.

The backbone of a DNA or RNA strand is composed of alternating sugar and phosphate molecules. In DNA, the sugar is deoxyribose, while in RNA, the sugar is ribose. The sugar and phosphate molecules are linked by phosphodiester bonds, which form a repeating pattern of sugar-phosphate-sugar-phosphate along the length of the strand. The nitrogenous bases, which are responsible for the information-carrying properties of DNA and RNA, are attached to the sugar molecules, and project from the backbone of the strand. The alternating sugar-phosphate backbone is a key feature of the double-helix structure of DNA, and is essential for maintaining the stability and integrity of the molecule.

The large intestine is the major site where water and electrolytes are absorbed, and feces form from the indigestible components of food.

The large intestine, also known as the colon, is responsible for the final stages of digestion and absorption in the gastrointestinal tract. Its main functions include the absorption of water and electrolytes and the formation of feces from indigestible components of food.

As undigested material passes from the small intestine into the large intestine, the large intestine absorbs water, electrolytes (such as sodium, potassium, and chloride), and some vitamins produced by gut bacteria. This absorption helps in maintaining the body's fluid balance and electrolyte levels. The colon also serves as a site for the fermentation of certain indigestible carbohydrates by gut bacteria, producing short-chain fatty acids that provide energy to the cells lining the colon.

The remaining indigestible components, along with bacteria, mucus, and cellular debris, gradually move through the large intestine, where water absorption continues. As water is extracted, the contents become more solid, and feces are formed. Feces primarily consist of undigested food residues, bacteria, water, electrolytes, and waste products. The feces are eventually eliminated from the body during defecation.

Inherited variation

Natural selection is a process that occurs when certain inherited traits or variations of a species give certain individuals an advantage in their ability to survive and reproduce in a given environment. Therefore, for natural selection to occur, there must be inherited variation within a population. Other conditions such as unlimited resources, a static environment, and a long life span do not necessarily have a direct impact on natural selection. However, these factors can affect the relative fitness of individuals with different inherited variations and thus influence the outcome of natural selection.

Food is rearranged through chemical reactions, forming new molecules that release energy as this matter moves through an organism. Molecules are broken apart and put back together to form new substances, and in this process, energy is released.

Explanation:

Hope this helps! :)

Food is rearranged through chemical reactions, forming new molecules that release energy as this matter moves through an organism.

Any material that an organism consumes for sustenance is considered food. The majority of food comes from plants, animals, or fungi and contains vital nutrients like carbs, lipids, proteins, vitamins, and minerals.

An organism consumes the material, which is then absorbed by the organism's cells to supply energy, support life, or promote growth. Varied animal species have different feeding habits that meet the demands of their distinctive metabolisms.

Omnivorous people have evolved to find food in a variety of habitats due to their remarkable adaptability. In the past, mankind obtained food mostly through agriculture and hunting and gathering.

B. A recognition molecule on the surface of the cells.

An antigen is a substance that is capable of triggering an immune response in the body. It is typically a foreign substance, such as a pathogen (e.g. a virus or bacterium), a toxin, or a non-infectious particle (e.g. pollen or dust), that is recognized by the immune system as being foreign and potentially harmful.

When an antigen enters the body, it is recognized by immune cells called B cells and T cells, which produce proteins called antibodies to help neutralize and remove the antigen. The antigen-antibody interaction is a key part of the body's immune response and helps to protect us against infectious diseases.

Antigens can also be present on the surface of our own cells, such as cancer cells or transplanted organs, and can trigger an immune response if they are recognized as foreign by the immune system.

Overall, antigens are important components of the body's immune system and play a critical role in protecting us against infectious diseases and other threats.

The first statement only, best explain(s) these results for the control plots the number and diversity of species was basically unchanged in keystone species are critical to the diversity and stability of an ecosystem.

An ecosystem refers to a community of living organisms that interact with each other and their physical environment in a specific geographic area. They are characterized by a complex web of relationships among different species, including producers, consumers, and decomposers.

Producers, such as plants, use energy from the sun to produce organic compounds that other organisms can use as food. Consumers, such as animals, feed on these producers or other consumers to obtain energy. Decomposers, such as bacteria and fungi, break down dead organic matter into its component parts, returning nutrients to the ecosystem. Ecosystems are not only home to a diverse array of species but also provide important services to human populations, such as clean water, air, and soil.

The correct order of events in cell communication are reception, transduction, response, and termination.

The order of events in cell communication involves four main steps. These four steps include:

Reception Transduction Response Termination Reception: The first step in cell communication is the reception of a signal molecule.

A signal molecule binds to a receptor protein in the plasma membrane of the target cell. A receptor protein is a protein that changes its shape in response to the binding of a signal molecule.

Transduction: Once the signal molecule binds to the receptor protein, the receptor protein changes shape and initiates a series of intracellular signaling cascades. This is called signal transduction. Signal transduction pathways are often composed of a series of protein kinases and second messenger molecules, which amplify and relay the signal from the receptor protein to downstream targets.

Response: The third step in cell communication is the response to the signal. The response can be any number of cellular changes, including gene expression, enzyme activity, or membrane transport. The specific response is determined by the type of signal molecule, the receptor protein, and the downstream signaling pathways.

Termination: The final step in cell communication is the termination of the signal. This can occur through a variety of mechanisms, including degradation of the signal molecule, endocytosis of the receptor protein, or deactivation of the downstream signaling molecules.

Overall, cell communication is a highly regulated and complex process that is essential for the proper functioning of all cells.

The true statement regarding IHPS is that it commonly presents in infants between 2 and 8 weeks of age.

Infantile hypertrophic pyloric stenosis is a condition that primarily affects infants, usually between the ages of 2 and 8 weeks. It occurs more frequently in males than females. The condition is characterized by the thickening and hypertrophy (enlargement) of the circular muscle of the pylorus, leading to the narrowing of the pyloric channel. This narrowing results in the obstruction of food passage from the stomach to the small intestine.

Infants with IHPS typically present with symptoms such as projectile vomiting, persistent hunger, weight loss, and dehydration. The vomiting is forceful and often occurs shortly after feeding. The exact cause of IHPS is not fully understood, but it is believed to have a multifactorial etiology involving both genetic and environmental factors.

Early diagnosis and surgical intervention, typically in the form of a pyloromyotomy, are crucial in the management of IHPS. This surgical procedure involves making a small incision in the thickened muscle to relieve the obstruction and allow for normal passage of food. With prompt treatment, infants with IHPS can recover fully and resume normal feeding and growth.
