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.

The thallus of a mold consists of long, branched, threadlike filaments of cells called _________ that form a tangled mass called a
Answer:
Hyphae; mycelium.
Explanation:
Fungi can be defined as living microorganisms that are eukaryotic in nature and are able to reproduce using both means of reproduction i.e both asexually and sexually. Also, fungi do not have chlorophyll but are of great importance to the human world both scientifically and practically.
A thallus can be defined as the vegetative or bodily structure of fungi. Thus, the various forms of fungi are;
I. Yeast.
II. Mushroom.
III. Mold.
A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.
The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.
What are hyphae and mycelium in fungi?Hyphae are the tubular projections of multicellular fungi that form a filamentous network. Fungal hyphae release digestive enzymes in order to absorb nutrients from food sources.
mycelium, the mass of branched, tubular filaments of fungi. The mycelium makes up the thallus, or undifferentiated body, of a typical fungus.
Thus, hyphae and mycelium is the correct answer.

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.

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth. The ocean's tidal energy causes water to cycle on the earth. The water from the oceans evaporate and form precipitation. The precipitation then condenses back on the surface of the earth. The earth's magnetic energy causes water to evaporate. The water condenses into water vapor once it becomes precipitation. The condensation then falls back to the surface of the earth. The sun's thermal energy causes water vapor to condense. This condensation then forms precipitation. This precipitation returns to the atmosphere for the cycle to continue.
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.
Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.
The ocean's tidal energy does not cause water to cycle on earth.
Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit
