Answer:

Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface.

What is the evidence of prokaryotes?

Scientists have concluded that prokaryote life forms preceded the more complex eukaryotes. All organisms on Earth are classified into two basic cell types. "Kary" means nucleus. "Pro" means "before," and prokaryotes have DNA in a freely floating ring that is not encased in a nucleus.

The trait of medium-sized leaves in iris is determined by the genetic condition PP′. Plants with large leaves are PP, whereas pl
dsp73

Answer:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

Explanation:

PP = large leaves

P'P' = small leaves

PP' = medium leaves

PP' was crossed with another PP' plant:

PP'   x   PP'

progeny = PP, 2PP', and P'P'

PP = 1/4  x 80 = 20 large size leaves plants

PP' = 1/2 x 80 = 40 medium sized leaves plants

P'P' = 1/4 x 80 = 20 small sized leaves.

<em>Hence the phenotypes would be:</em>

<em>20 large size leaves plants</em>

<em>40 medium sized leaves plants</em>

<em>20 small sized leaves.</em>
