Answer:

(1) Their chemical structure is critical to their ability to function.

Explanation:

All enzymes, antibodies, and hormones have a similarity like they all have a particular and unique chemical structure which is critical to their ability to function. If they lose their shape then they will lose their function because in enzyme there are active site which have a particular shape in which substrate will bind.

Each antibody bind to specific antigen according to the chemical shape they have and hormone also binds to their receptor so they should have that shape that can fit into the receptor.

Viruses _____.

Montano1993 [528]

viruses are tiny bundles of genetic material which is carried in a viral coat.

<u>Explanation:</u>

The virus is generally a parasite that needs a host to become active and to reproduce. It cannot reproduce without the host.
The tiny bundle consists of genetic material and protein. The virus consists of capsid and nucleic acid. This capsid is said to be the protein coat.
This capsid consists of either RNA or DNA. virus replicate themself within the host body by using its genetic material along with the mechanism of the host.
Thus after replicating the virus need to get out of host cell, It is performed by two types budding or lysis( bursting the host cell ).

Answer:

The answer is 6.4 × $10^{-20}$ Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × $10^{-12}$ N

displacement = 8.0 nm = 8.0 × $10^{-9}$ N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × $10^{-12}$ × 8.0 × $10^{-9}$ = 64 × $10^{-21}$

= 6.4 × $10^{20}$ Joules (in standard form)
