The correct answer is tick on a dog.
The parasitic relationship can be defined as the relation in which one organism feeds on the other organism for their nutritional purpose. It can also harm the other organism by any means. Here, tick on the dog is dependent on the dog for its nutritional requirement. This is an example of parasitic relationship between dog and tick.
Answer:
Natural selection doesn't really choose what animal/species is going to survive it's all based on the environment they live in. While a blue bird does well in the jungle it may not do well in the desert. For individuals it's based on their genes and genetics. Some are more prone to have a trail that doesn't benefit them and in fact, harms them in their environment. For populations you will see lots of the same animals but with different traits so some may do better in the wild than others because of those traits. A population is more likely to be successful because you do better when working with others. So animals have a better chance to survive if there is more diversity.
This statement is mostly false. While all organisms do share basic needs to sustain life, there is a wide variety of strategies employed to meet these needs. For example, while most plants receive nutrients from soil, some live in soils which do not fully meet their needs. Such plants sometimes kill and use animals in order to meet these needs (i.e. venus flytrap) or partner with bacteria that produce some of the nutrients they need (i.e legumes).
Answer:
I'm pretty sure the answer is b because since multicellualr organisms have more cells, they carry out more functions rather than a singlecellular organism.
Explanation:
Having genes with related function in one transcription unit is important because such transcription unit will have a single on and off switch. This switch can control expression of this group of genes in a more coordinated manner than when each gene has its own regulatory system. It ensures that these genes are transcribed together as a unit and therefore there functions are highly coordinated since they are related.
