C) it regulates what goes in and out of the cell
Usually the membrane is the organelles that acts like a door. They decide what type of nutrients and molecules go into the cell.
Dependent reaction is the factor that is observed and measured
<span>The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.</span>
A protonema (plural: protonemata) is a
thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life
cycle..
<span>A haploid gametophyte ( each of whose cells contains a fixed number of
unpaired </span>chromosomes) gives rise to a <span>diploid sporophyte</span>,.
Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes
that grow into sporophytes.
This is a physics question, not biology, but...
f=1/T where f is frequency and T is the period.
f= 1/(1/3)=3
frequency =3 Hz
1. Is A
2 Is B
Because A and T in the DNA sequence goes together so they both have to have the same amount same goes for C and G
