HIV is unique because it copies the information for reproduction from RNA back into DNA.
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.
What is virus ?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.

Jennipher was asked by her mother to take a certain kind of fish in a bucket full of water so that she can prepare it for meal.when jenipher touched the fish she felt like an electric shock to her hand. what behavioural mechanism did the fish generate?
The fish use reacting behavioural mechanism in order to protect itself from the danger.
The fish uses reacting behavioural mechanism when the fish sense any type of danger surrounds it. This behaviour is a type of defense mechanisms which is used to defend and protect itself.
The fish apply electric shock in order to protect itself from the attackers and give harm to the other organisms which comes in contact with it so we can conclude that the fish use reacting behavioural mechanism in order to protect itself from the danger.

Proteins are made on cell structures known as.…
Answer:
Ribosomes
Explanation:
Ribosomes are organelles made of ribosomal RNA (rRNA) and protein. They exist in the cytoplasm of the cell and are the site of protein synthesis in all cells. Ribosomes read the codons in mRNA and catalyze the creation of peptide bonds between the appropriate amino acids, forming polypeptide chains.

Which of the following must be true in order for natural selection to occur?
Group of answer choices
There must be variation in traits in the population
The trait must cause the individual to evolve
The trait must have no other advantage in fitness
The trait must be for the good of the species
The trait must be heritable
The trait must advance the goal of evolution
Answer:
For natural selection to occur, it is true that there must be genetic variation in the population.
Explanation:
According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.
For natural selection to occur, three fundamental conditions must exist:
A trait that can be inherited from one generation to another.
The trait is subject to variability between subjects of the same species.
Genetic variability can determine the possibility of reproductive success and survival.
Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.
For natural selection to occur :-
There must be variation in traits in the population.The trait must cause the individual to evolve.The trait must be for the good of the species.The trait must be heritable.The trait must advance the goal of evolution.What is Evolution?It is the change in the characteristics of a species over several generation.It relies on the process of natural selection.

Use each of these terms correctly in your description:
community
population
ecosystem
individual
biotic
abiotic
The ecosystem is a habitat in which different types of biotic and abiotic organisms coexist.
How is the ecosystem made up?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.

why is the dominant allele seen in a heterozygous individual
Answer: Since it's the DOMINANT allele that means that it will take over reccesive allele that's why it's shown.
Explanation: A heterozygous individual is an individual where the have both the dominant and reccesive allele for a trait. The dominant allele will always be stronger than the reccesive allele. This results in the dominant allele being shown.
Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation.
The normal period of gestation is about 40 weeks.
The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days.
The stages of human development include, in order: zygote, blastocyst, embryo, and fetus
A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula.
Changes to the form of the embryo come from differentiation and growth.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

There are two birds that live in the same type of tree, same climate, and eat the same type of fruit. However, one is nocturnal (awake at night) and the other is diurnal (awake in the day). Explain why these two birds are considered to have different niches.
Answer: different species
Explanation: They live in the same community like a Gouldian finch and a Double-Barred finch but are different species
However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.
What shows the low light in the evening?The hours of low light in the evening shows that it would be when humans would be most at risk from dangers. Species might make sense to seek shelter during this period.
As a result of their divergent evolutionary paths, various species have evolved in various ways to adapt to their habitats. The reason a certain species is nocturnal or diurnal has a variety of different potential causes. Perhaps at night, when light levels are low, when humans would be most exposed to dangers. The decision to seek sanctuary during this time may therefore be justified. Considering the various predatory dangers that mice and rats encounter, it is possible that being active at night reduces the threat posed by predators like birds who utilize their visual senses to identify prey.
