Answer: option A - denature
Explanation:
Microbial control agents are KNOWN to DENATURE cell proteins as a step in pathology of many diseases.
And because PROTEINS ACTIVITY depends on their three dimensional configuration, microbe attack and BREAK the bond in order to penetrate the cell membrane.
So, the ONLY right option is A
Answer:
25%
Explanation:
We have 2 independent genes with 2 alleles each: L/l and W/w
- W_: whiskers
- ww: no whiskers
- L_: long whiskers
- ll: short wiskers
Individuals with short whiskers will have the genotype <em>WWll </em>or <em>Wwll</em>.
<u>A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:</u>
<h3>WwLl x wwll</h3>
-The homozygous rat will produce only <em>wl </em>gametes.
-The heterozygous rat will produce the following gametes: <em>WL</em>, <em>Wl</em>, <em>wL</em>, <em>wl</em>.
If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.
