Two diverse species naturally breed an offspring, and selective preserves raver new traits in a given environment, (they evolve).

Is called the cotton Boll. Hope this helps:)
She should have to classify this animal under pseudocoelomates category. The body cavity of these animals are filled with fluids. Internal organs are covered by the fluid filled space. The body cavity serves as the hydrostatic skeleton and have other functions such as digestion of food and waste removal.
The question lacks the diagram. The diagram has been attached below.
Answer:
1.
Explanation:
Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.
The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.
Thus, the answer is 1.
They are both important because mechanical has to do with physical - cause mechanical means physical, so chewing your mouth is physical (you break your food into smaller pieces physically). And then chemical digestion is when food and saliva mix together. They happen when breaking down food into nutrients - enzymes. Enzymes are important for that process, because they make a nutrient.
Hope this helps!!
