Answer:

It can dissolve more things than any other substance.

Explanation:

Water is considered the universal solvent because it can dissolve more substances than any other liquid. This is because of its unique molecular structure and properties. The water molecule is polar, which means it has a slightly negative charge on one end and a slightly positive charge on the other end. This polarity allows water molecules to attract and surround charged particles, such as ions, and polar molecules, such as sugars and amino acids.

Competition- An interaction to gain a share of a limited resource. An example is an interaction between vultures, hyenas and a dead hippo.

When resources are insufficient to meet the demands of all the organisms living in a community, competition occurs when organisms of the same species or other species use the same resources.

Within a species, either all individuals get some of a resource they need, like food or space, or some get enough to meet their needs while others, who are shut off from the resource, perish or are compelled to live in a less desirable or marginal location. The majority of the time, young people in a population suffer negative effects.

The less likely it is that two different species may coexist in the same location, the closer their requirements must be. Although they may be forced into direct competition when resources are low, species with comparable requirements can occasionally coexist in the same region if they differ in behavioural ways like feeding patterns, breeding preferences, or activity periods. When two species coexist in small populations, their members frequently have smaller-than-average bodies or have a poor reproductive rate.

Interdependence- An interaction between two individual organisms, an interaction between animal or plant species.

The two sentences that describe why classification systems are still changing are:

Classification systems in biology are hierarchical frameworks that organize living organisms into groups based on their evolutionary relationships and shared characteristics. These systems are used to create a system of order, allowing for the identification and comparison of different organisms.

The most widely used classification system in biology is the Linnaean classification system, which was developed by Swedish biologist Carl Linnaeus in the 18th century.

In recent years, advances in molecular biology and genetics have led to the development of new classification systems that take into account the evolutionary relationships between organisms at the molecular level.

Answer:

During the process of metamorphic rock formation, there is a transformation or change in the mineral composition and texture of the original rock due to high heat, pressure, or chemically active fluids. As a result, the system goes through a significant change.

The system may be considered "stable" again once the metamorphism process has completed and the resulting metamorphic rock has reached equilibrium - meaning that there are no longer any changes occurring within the rock due to external factors. The stability of a metamorphic rock depends on various factors such as the mineral composition, temperature, pressure, and chemical environment. Once these factors balance out and reach a steady state, the system can be considered stable again.

Answer: The change that occurs is the eroding, or breaking down of a rock into sediments, the movement and deposition of the sediments, and the compaction and cementation of the sediments to form a new rock. The system is stable again once the new rock is formed.

Explanation:

Arable land is defined as land that is suitable for farming, and is typically used for the production of crops and livestock feed. The term "arable" is often used to describe land that has been cultivated, plowed, and is ready for planting. This land is usually nutrient-rich and capable of supporting a variety of crops such as wheat, rice, corn, and soybeans, as well as forage crops for livestock such as alfalfa, clover, and grasses.

Farmers rely on arable land to produce food and feed for animals, and this land is a crucial resource for meeting the world's growing demand for agricultural products. Arable land is a finite resource, and it is important to use it efficiently and sustainably to ensure that future generations have access to the resources they need to produce food and feed for a growing global population.

Answer: phenylalanine.

Explanation:

The tRNA with an anticodon GAA should attach the amino acid phenylalanine.

The identified pattern that is seen here is that : pairing bases (AT and GC) are both very close in numbers . The values are sometimes off by just 0.5

The Chargaff rule, also known as Chargaff's ratios or base pairing rules, states that in a double-stranded DNA molecule, the amount of adenine (A) is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). This is sometimes expressed as A=T and G=C.

Erwin Chargaff, an Austrian-American biochemist, discovered this rule in 1949 by analyzing the base composition of DNA from various species. He found that the amounts of A, T, G, and C in DNA differed between species, but within a species, the ratios between A and T, and between G and C, were always roughly equal.

(b) Lice feed harmlessly on the feathers of birds. commensalism

(c) A cowbird removes an egg from a robin's nest and replaces it with one of its own. commensalism

(d) An orchid plant grows on the branch of a tree. The tree remains healthy.​ commensalism

Answer:

A: Mutualism

B: Parasitism

C: Commensalism

D: Commensalism

Explanation:

Mutualism is a relationship between two species of organisms in which both benefit from the association.

Commensalism is a type of relationship between two species of a plant, animal, fungus, etc., in which one lives with, on, or in another without damage to either.

Parasitism is a relation between organisms in which one lives as a parasite on another.

PART A: The yucca plant is necessary for the yucca moth larvae to live because it is their only source of sustenance. The moth pollinates the plant, and in return, the plant provides sustenance for the moth, creating a harmonious partnership.

PART B: Different types of biting lice, fleas, and louse bugs are commensals because they graze safely on avian feathers and the skin flakes shed by animals.

PART C: A female cowbird looks for other species' female birds that are busy depositing eggs in a quiet manner. After locating an appropriate host, the cowbird will break or take one (or more) eggs from the resident bird's nest while it is gone and substitute them with one (or more) of her own.

PART D:

Commensalism is the term used to describe the interaction between plants and orchids. When two species coexist, one of the species benefits while the other is unchanged.

Answer:

Explanation:

In general, the more tightly the DNA is wound around the histone proteins in a chromosome, the more difficult it is for RNA polymerase to access a gene and make a copy of that gene. This is because the tight winding of DNA around histones creates a compact structure called chromatin, which can restrict the access of RNA polymerase and other transcription factors to the gene. Therefore, genes that are tightly packed within chromatin are generally less accessible for transcription, while genes that are less tightly packed are more accessible for transcription.

Three major types of insect development: a) Ametabolous development typified by the silverfish, b) Hemimetabolous development typified by the cockroach; in some hemimetabola such as termites and grasshoppers there may be more than one stage with wing pads that could be called nymphal; c) Holometabolous development 

The correct answer is option C) exploration of different niches, avoiding competition between life stages.

Each phase of development presents a different habitat and niche, which prevents competition between species, that is, intraspecific competition. In this way, the effectiveness of the animal within its environment is increased, as well as its adaptation to the environment.

The other alternatives highlight stages of development that exist, but are not related to the increase in the number of species or to the justification presented.

Answer:

Explanation:

Electrolytes are substances that conduct electricity when dissolved in water or melted. They are typically ionic compounds that dissociate into positive and negative ions in solution. These ions are free to move and carry an electrical charge, allowing them to conduct electricity.

Answer:

The statement is incorrect.

Succession is a gradual and predictable change in the species composition of an ecosystem over time, starting from bare rock or sand and ending in a stable, self-sustaining community called a climax community.

In the scenario described, the deposition of new sand and the formation of new dunes can provide new habitats for pioneer species, which are the first to colonize disturbed areas. These species are usually opportunistic and fast-growing, such as grasses and shrubs. Over time, as these species die and decompose, they contribute to the formation of soil, which allows for the establishment of other species, such as trees and woody plants.

However, since the scenario involves a coastal region, the newly formed sand dunes can be highly vulnerable to erosion and flooding, which can interrupt the successional process and prevent the establishment of a climax community. In addition, the deposition of new sand can also affect the chemical and physical properties of the soil, which can limit the growth of certain plant species and affect the food web of the ecosystem. Therefore, it is not certain that the region will undergo succession to become a climax community.
