Answer:
It will depend on the type of virus that infects the host's cells. For example, if it is a poliovirus, the answer will be <em>"D. poliovirus protein coats and poliovirus genetic material"</em>
Explanation:
A virus is composed of genetic material encapsulated by a protective coat protein (capsid). The genetic material of a virus can be either DNA or RNA and single-strand or double-stranded (either DNA or RNA). Moreover, the capsid may be surrounded by an additional spikey coat known as envelope. During infection, a virus invades the host´s cells to replicate both its genetic material and its proteins (they use host cellular machinery to synthesize new viral proteins). Depending on the type of virus, they can integrate and replicate its genetic material into the host genome (DNA viruses and RNA retroviruses) or replicate its genetic material outside the host genome (RNA viruses in general).
Answer : Radiational Cooling
Explanation: Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable. These air masses originate over northern Canada and Alaska. They move southward, east of Rockies into the Plains, then eastward.
Answer:
Explanation:
Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.
C. The strongest species survive
Meiosis is the mechanism used for producing gametes in multicellular organisms whereas it does not play any role in unicellular organisms.
Meiosis produces gamete, or sex, cells and occurs only in multicellular organisms.
Mitosis produces somatic, or body, cells and can occur in both multi and uni cellular organisms.
