Classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).

There are many types of classification systems that are used for different purposes. The classification of organisms takes place in the form of a classification system called Linnaean classification.

Linnaean classification involves the use of organisms grouped using a hierarchy called taxa which includes taxonomic levels and taxonomic groups that animals are placed in based on their characteristics and even shared ancestry.

The different levels of biological classification are as follows:

Species » Genus » Family » Order » Class » Phylum » Kingdom » Domain

It changes over time as scientific studies find new evidence.

Explanation:

"Particles migrate in diffuion from a low-concentration area to a high-concentration area."

The statement is false.

Diffusion is the movement of a substance's individual molecules over a semipermeable barrier from an area of higher concentration to an area of lower concentration.

Diffusion is the total net transfer of a substance from one concentration to another. Diffusion is fueled by a gradient in the chemical potential or Gibbs free energy.

The movement of materials into and out of cells is facilitated by diffusion. The molecules move from an area of higher concentration to an area of lower concentration until the concentration is the same everywhere.

Due to the possibility of random molecule movement, diffusion happens in gases and liquids.

The incorrect statement concerning evaporation is: "Increasing the surface area of the liquid decreases the rate of evaporation." Option A is correct.

In reality, increasing the surface area of the liquid actually increases the rate of evaporation. This is because evaporation occurs at the surface of the liquid, and a larger surface area provides more space for molecules to escape into the vapor phase. Evaporation is a process by which a liquid changes into a gas or vapor state.

It occurs when molecules near the surface of a liquid gain enough energy to overcome intermolecular forces and escape into the surrounding space as vapor. Increasing the temperature of the liquid is one of the factors that can significantly affect the rate of evaporation. As the temperature rises, the average kinetic energy of the molecules increases, resulting in more molecules having sufficient energy to transition from the liquid to the gas phase, option A is correct.

The osmotic solution that the novice gardener would suggest using to best return the plants to full health would be a hypotonic solution.

Osmosis  is the process by which molecules of a solvent, typically water, pass through a semipermeable membrane from as concentrated solution to a more concentrated solution, resulting in a balance of concentrations on both sides of the membrane. There are three types of osmotic solutions: Hypotonic, Hypertonic, and Isotonic.

A hypotonic solution is a type of osmotic solution in which the concentration of solutes is lower outside the cell than inside the cell, and the solvent moves from a hypotonic solution to a hypertonic solution, resulting in swelling and growth.The hypertonic solution contains more dissolved solutes than the hypotonic solution. As a result, water will diffuse from the hypotonic solution to the hypertonic solution, increasing the amount of water in the hypertonic solution. This increase in water will cause the cells to swell, making the plant's cells turgid.

Hence, a novice gardener would suggest using a hypotonic solution to best return the plants to full health.

Monkeys and hominids are believed to have diverged in the tropical forest ecosystem.

Yes, the divergence between monkeys and hominids is believed to have occurred in the tropical forest ecosystem. It is thought that the earliest primates evolved in the trees of the tropical forests, and that the divergence between monkeys and hominids occurred around 25 million years ago in this ecosystem. As primates continued to evolve, some species began to move into other habitats such as grasslands and deserts.

An ecosystem is a biological community of interacting organisms (plants, animals, and microbes) and their physical environment. It includes both living and nonliving components of the environment, such as soil, water, air, and sunlight. Ecosystems can be large, such as a rainforest, or small, such as a pond.

Cyclic interactions play a significant role in evolution by driving co-evolutionary processes between different species or populations. These interactions involve reciprocal changes and adaptations between species that interact closely with each other, often leading to evolutionary changes in both parties involved.

Cyclic interactions can take various forms, such as predator-prey relationships, host-parasite interactions, or mutualistic symbioses.

In predator-prey relationships, for example, cyclic interactions can drive evolutionary changes in both predator and prey populations. Predators exert selective pressure on prey, favoring individuals with traits that make them more difficult to capture or consume. Over time, this can lead to the evolution of defensive mechanisms in prey, such as camouflage, toxicity, or enhanced escape abilities. In response, predators may evolve strategies to overcome these defenses, such as improved hunting techniques or specialized adaptations for capturing certain prey. This ongoing arms race between predator and prey can drive co-evolutionary dynamics and contribute to the diversification and adaptation of both species.

Similar co-evolutionary processes occur in host-parasite interactions. Parasites impose selective pressures on their hosts, favoring hosts with genetic or physiological traits that provide resistance or tolerance to the parasite. Hosts, in turn, may evolve countermeasures to defend against parasites, such as immune system adaptations or behavioral changes. This dynamic interplay between hosts and parasites can lead to the continual evolution of more potent parasites and enhanced defenses in hosts, driving the evolution of both parties.

Mutualistic interactions, where two species benefit from each other, can also contribute to evolution through cyclic interactions. For instance, in plant-pollinator interactions, plants rely on pollinators for reproduction, while pollinators depend on plants for food. This mutual dependency can lead to the evolution of specialized traits in both plants and pollinators, such as specific flower shapes, colors, or behaviors that maximize their interaction efficiency. As these traits evolve, they can result in the diversification of both plant and pollinator species.

Immortal-Cultured Indefinitely

Explanation:

As stated in the text:

"The isolated B-cells are made to fuse with immortal tumor cells and can be cultured indefinitely in a suitable growing medium."

Answer:

Yes

Explanation:

This can be explained with the concept of induced resistance. it is the ability of a plant to respond the certain chemical released from the damaged body parts,The diffusion of the chemical stimulates all other plants parts and other plants to be less tasty and therefore not pleasant to eat. Thus the more the extent of damage to the plant,the higher the volume of chemicals released and therefore the less tasty the plants and lower the damages-negative feedback mechanisms. Since this restored the plants to relatively constant internal environments,this is homeostasis.

Hornworm caterpillar damages tomatoes plants leaves,leaving holes.When a tomato plant is eaten,it releases chemical substance called methyl jasmonate. The latter would be received by adjacent plants parts or other tomato plants. The receptive tomatoes plants therefore becomes less tasty. Hence the caterpillar after destroying  the initial part of the tomato plants would not be able to continue with the feeding and therefore feed on one another leading to their death,turning them to cannibal caterpillars.

Since in an attempt to maintain the relatively constant internal environment plant releases methyl jasmonate to prevent futher damage and therefore ensures stability of the plant.

The phenomenon of global warming has been casting a stark life or death shadow over many major U.S. cities. The increase in temperature due to the emission of greenhouse gases may cause an extreme heat wave that could claim thousands of lives in these cities.

Even if nations honor only their current commitments for curbing emissions, the global average temperature is expected to rise by 3 degrees Celsius, which some scientists say is likely.

A major heat wave in New York City could claim up to 6,000 lives, while similar events in Los Angeles and Miami could kill over 2,500 and 2,300 people, respectively, according to the new research.

However, if the U.S. and other nations take aggressive measures to limit warming, many heat-related fatalities could be prevented.

The article was published in 2019, but there is little evidence to suggest that the situation has improved significantly. Heat-related issues have claimed several lives in Vancouver, B.C. and many others in Los Angeles and Florida this past summer.
