Answer:
100%
Explanation:
A pea plant homozygous for the trait of smooth seeds;
let that be = ss
A pea plant that is homozygous for the trait of wrinkled seeds;
let that be = ww
if ss crosses with ww; the F1 produces seeds that are all smooth
i.e ss × ww = (sw, sw, sw, sw)
From the question, we are to find the percentage of the second generation that will produce smooth seeds after self fertilization occurs.
i.e sw, sw, sw, sw × sw, sw, sw, sw
= the result will yield ssww for all F2 progeny
∴ the percentage of plants that will have smooth seeds when the F1 generation is self-fertiized is 100%
Answer:
Viruses and bacteria helps to build up our immune system, specifically our adaptive immune response such that we will be able to eliminate such pathogens when our body comes into contact with them. This builds up the resilience of our immune system over time, similar to how vaccines work.
<span>The number of humans on earth is experiencing exponential growth. The amount of growth is proportional to the amount of humans on earth to begin with; the more humans there are, the more growth there will be.</span>
Both plant and animal cells have a nucleus. However, animal cells don’t have a cell wall but they have a cell membrane. Plant cells have a cell wall and a cell membrane. Plant and animal cells have different organelles.
