Prokaryotes don't have a nucleus, Eukaryotes have a nucleus as well as organelles, they perform functions together with other specialized cells where prokaryotes can be individual and functioning organisms.
I believe this is a bit of a trick question, while you are right about both B and D, they both preexist they just develop into other structures. I believe the correct answer is A since the nerve cord is hollow not solid.
Answer:
M
=
2.0
m
o
l
L
−
1
Explanation:
The molarity,
M
of this solution can be calculated by a formula which is;
M
=
n
V
where;
M
= Molarity of solution
n
=Number of moles of solute
V
= Volume of solution in Litre
Given,
n
=
4.0
moles and
V
=
2.0
L, so we have enough information to calculate the molarity of the solution;
M
=
n
V
M

because

Answer:
Responsiveness to the environment/adaptation. This is one of the 8 characteristics of living things.
Explanation:
Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.
