Answer:
The cell type I work with (chondrocytes) are really similar between different species. The tissue they make is very similar between species and that is why they are a great model for looking at human joint tissues. In terms of the basic elements of the cell, all animal cells are very similar, i.e. they do not have a cell wall and they have a nucleus. Dogs have different features to us because they have adapted and evolved to have the features they have. For example, when a puppy is developing, cells receive signals to move to one end of the puppy and develop the tail. A long time ago our ancestors had tails but over millions of years we have lost that feature because we don’t need it to survive.
Explanation:
Single nucleotide polymorphism or point substitution
Explanation:
By NATURAL SELECTION, the green grasshopper in the population will increase with succeeding generations – also meaning the allelic frequency for green color with increase. This is because the grasshoppers blend / camouflage well with their green environment hence are less exposed to their predators that the brightly colored grasshoppers. These grasshoppers are therefore more likely to reach maturity and pass down their genes by reproduction.
