They all develop gills, slits and tails
<span>1) It is the chromosomes, however, that assort independently, not individual genes.
2) </span> <span>It tells you they're really far apart.
You see, there's this phenomenon called crossing over. Chunks of DNA get randomly swapped between homologous chromosomes. If two genes are close together they're usually swapped together and if they're far apart (say, on opposite ends) they're probably never going to be swapped together because half a chromosome doesn't normally cross over at once.

3) <span>Sexual reproduction, because it results in offspring that combine alleles from two different individuals. </span>
<span>(Crossover is fine and dandy and you should mention it, but you'd get a C if you didn't mention that two different individuals are contributing genetic material to the offspring)</span>
Answer: Option A.
Different beaks were available
Explanation:
Variation is the difference between traits, cells, or characteristics between organisms of any species which is caused by change in genetic information or effect of environmental factors on the expression of genes.
From the question, different beaks were available because there is variation or differences in shapes, sizes and expression.
Answer:
The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere

From this, you hypothesize that this lineage of dinoflagellates was the result of ENDOSYMBIOSIS. It benefits both organisms.
<h3>What is endosymbiosis?</h3>
Endosymbiosis is an ecological relationship where one organism is incorporated inside another and it benefits both.
The theory of endosymbiosis states the eukaryotic cells emerged via this type of relationship.
According to the theory of endosymbiosis, prokaryotic organisms that were introduced into primitive eukaryotic cells led to the formation of chloroplasts and mitochondria.
