What is the classification of virus
Answer:
Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.
Many viruses attach to host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.
The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.
What is Virus?A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.
Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.
Class 1: Double-stranded DNA viruses.
This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.
Class 2: Single-stranded DNA viruses.
Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.
Class 3: Double-stranded RNA viruses.
Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.
Class 4: Single-stranded RNA viruses (positive sense).
Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.
Class 5: Single-stranded RNA viruses (negative sense).
Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.
Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.
Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.
Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.
Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.
Therefore, it is well described above.

PLZ HELP IM TAKING MY EXAM!! which of the following best explains the impact of mrna being double stranded before translation
Answer:
Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.
Explanation:
The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.
Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.
If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.

through muscle contractions
by using special hairs
by producing estrogen
through secretions of glands
Answer:
by using special hairs
Explanation:
When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus.

The increasing demands for fossil fuels has led governments and businesses to
consider several possibilities to solve the energy crisis. Which solution will reduce the
impact of this crisis on the environment and future generations?
(1) increase the number of drilling sites for crude oil in North America
(2) build more power plants away from population centers
(3) limit the number of people in each vehicle
(4) develop alternative fuel sources that can be produced from renewable
resources
The rise of fossil fuels demands various nations has created problems for the government to meet the increasing supplies as fossil fuels are fast depleting and heavily pollute the environment at large.
The government is trying to build more alternative fuel sources and produce some renewable resources in case of fossil fuels get depleted completely.Hence the option 4 is correct.

Answer:

Explanation:
Everyone's DNA is unique unless they are identical twins or if you have some kind of transplant.
Of the following best explains why DNA fingerprints can be used to identify an individual, such as from a crime scene sample it is the situation that Each individual has a unique DNA sequence, with the exception of identical twins. The correct answer is option 4.
What are identical twins ?These are the babies that are formed from multiple fusion of gametes and resulting into double fertilization.
DNA is inherited from both maternal and paternal parents. Yes, it is so but the pattern is not same as it will be possible to get the idea of the pattern and analyse along with the prediction of the genome as only few % is predicted.
DNA is used to make proteins during protein synthesis and this situation is clearly correct too but the fact is that this is not helping in the case of DNA fingerprinting where it is not easy to firstly see the DNA pattern then the RNA and then the amino acids and then the proteins.
