Answer: crossing over allows for genetic variation
Explanation:
crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).
Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.
Answer: To do different kinds of jobs
Explanation:
Yes that's right, its True, are structures that have specific functions
Answer:
population = 600
heterozygotes = 2pq
The homozygous recessive percentage = 
q = 0.1
Solve for q:
∴ q = 
∴ q = 
∴ q = 0.316
solve for p:
for p + q = 1,
thus p = 1 – q = 1 – 0.316 = 0.684
The heterozygotes = 2pq
2pq = 2 x 0.316 x 0.684 = 0.432
600 x 0.432 = 259.2 = 259
so, the population reaches Hardy Weinberg equilibrium, 259 of indviduals should be heterozygous for this trait.
Hence, the correct answer is 259

Salutations!
<span>Put the following in order from least complex(1) to most complex(4). cell, organism, organ, organ system.
Cell is the basic and the smallest unit of life.
Organ is a wedge of a living thing/ organism that has a function to carry along. A group of organs is called organ system
Organ system is a group of organs working together to carry out the functions along.
Organism is separate living thing that lives through the functions carried along by the organ system.
Lets put the terms in order!
</span>→ 1) Cell
<span>
</span>→ 2) Organ
<span>
</span>→ 3) Organ system
<span>
</span>→ Organism.
