Answer:
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. and I can't think of the other one sorry.
Explanation:
Answer:
Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
Explanation:
The main advantage of sexual reproduction is that it increases the genetic variation in the species by creating new combinations of alleles.
However, asexual reproduction produces more offspring, as it is usually a quicker method of reproduction. It also does not require the organisms to socialise to mate.
Sexual reproduction does not reduce the rate of mutation, which is influenced by environmental factors as well as the genome itself.
In my opinion we would not have clouds because the clouds is our water vapor
Answer:
Diffusion rate is 1.96 × 
/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = 
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = 
r = 
= 
= 7.5 mm = 0.75 cm
area = 
× 
= 1.7679
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = 
= 0.0019643 /s
Diffusion rate is 1.96 × /s
