Answer:
I do not agree with this statement.
Explanation:
Plants and some bacterias are autotrophic, meaning that they manufacture their own food from basic elements using an energy source in an anabolic process. Plants mostly utilize sunlight which they trap with the help of their green pigmentation called chlorophyll. Bacteria on the other hand mostly get their energy source by splitting chemical compounds, utilizing the liberated bond energy of the compound (examples is the sulfur bacteria) to fuel their food building process.
Answer:
A shared character is one that two lineages have in common. Because organisms evolve from common ancestors and then diversify, the logic is stating that the more shared characteristics two organisms have, the closer their evolutionary relationship is.
Explanation:
Out of the following give choices;
a. All DNA strands
contained only the heavy nitrogen isotope.
b. Half of the DNA strands contained only the light nitrogen
isotope.
c. All DNA strands contained both heavy and light nitrogen
isotopes.
d. All DNA strands contained only the lighter nitrogen
isotope.
The answer is b. Meselson–Stahl experiment demonstrated the semi-conservative model of DNA replication.
When DNA is replicated, one strand of the new double
helix strand is the parent's strand while the other is the newly synthesized
one. This made the semiconservative model stand out over the other two, dispersive
and conservative models.
When crossing alleles for color, you get
25% pp
50% Pp
25% PP
White flowers are recessive, so there is a 1/4 chance
And when crossing alleles for shape you get
25% rr
50% Rr
25% RR
Wrinkled seeds are recessive so there is a 1/4 chance
Since you are looking for white flowers AND wrinkled seeds, you need to multiply 1/4 x 1/4, giving you a 1/16 chance that the offspring will have these two traits
