Explanation:

True. it is a virus and that's how viruses reproduce.

HIV is a virus which is unique because it copies the information for reproduction from RNA back into DNA, the statement is true.

A virus is a nonliving thing which is a  connecting link between living and nonliving organism, depend on living host cell for their survival.

virus contain a chain of nucleic acids (DNA or RNA) which  use different parts of the cellular machinery to reproduce, and releases the replicated nucleic acid chains

A virus has a protein coat or protein envelope allows the virus to survive between hosts act as a protective covering, do not have cells and lack a cell wall .

The protein coating is called as the capsid, genetic element present and is characterized by the evolution of the virus and the host.

It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.

In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.

An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.

In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.

A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.

A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).

In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

Answer:

Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

Carbon is both the foundation of all life on Earth, and the source of the majority of energy consumed by human civilization. [Photographs ©2007 MorBCN (top) and ©2009 sarahluv (lower).]

Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.

Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.

Draft diagram of the carbon cycle.

This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon. (Diagram adapted from U.S. DOE, Biological and Environmental Research Information System.)

Over the long term, the carbon cycle seems to maintain a balance that prevents all of Earth’s carbon from entering the atmosphere (as is the case on Venus) or from being stored entirely in rocks. This balance helps keep Earth’s temperature relatively stable, like a thermostat.

This thermostat works over a few hundred thousand years, as part of the slow carbon cycle. This means that for shorter time periods—tens to a hundred thousand years—the temperature of Earth can vary. And, in fact, Earth swings between ice ages and warmer interglacial periods on these time scales. Parts of the carbon cycle may even amplify these short-term temperature changes.

The global carbon cycle model describes the evolution of carbon mass in the mantle (Cm), the combined reservoir of ocean and atmosphere (Co+a), the continental crust (Cc), the ocean crust and floor (Cf), the kerogen (Cker), and the biosphere (Cbio).

Carbon on the dynamic planet can move from one of these realms to another as part of the carbon cycle.

Thus, above-mentioned are the steps involved in a carbon cycle.

Answer:

In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Other changes in limiting factors will cause a population to decrease.

Explanation:

hope it helps.

Answer: Two or more limiting factors may work in conjunction with one another.

Explanation:  For example, parasites and disease. In this case, we have a biotic factor (parasites) combined with an abiotic factor (a disease-causing virus). Combining these limiting factors creates a deadly team that can have an even greater impact on a population's growth and survival.

The ecosystem is a habitat in which different types of biotic and abiotic organisms coexist.

The ecosystem in which we live is coexisting with different types of population. Biotic and abiotic organisms coexist, interdependent organisms that share the same habitat. Through different processes such as predation, symbiosis, parasitism, they will disintegrate and reform to give themselves the energy and nutrient cycle.

The relationship that occurs between the community and its environment will be a flow of matter and energy in the ecosystem. There will also be different types of ecosystems such as marine, terrestrial, microbial and artificial. In all of these there will be food chains between the different species.
