The population of cactus dwelling birds will decrease and that of the animal they eat will increase.
Explanation:
When cacti is removed from the desert ecosystem, the birds that have their nest on the cacti will no longer have a home so they will migrate to other areas with favorable ecosystem.This will reduce the number of birds in this ecosystem.In turn, the animals that were feed by the birds will have the chance to multiply in numbers because a predator has been removed in the ecosystem.

Answer:
Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.
The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.
Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.
For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
<h3>Question from alternative source</h3>
Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
- silent
- missense
- nonsense
- deletion
Answer:
Nonsense
Explanation:
Nonsense mutations describe mutations that produce a premature stop codon. The stop codons are UAG, UAA, and UGA. A way in which this could arise is, for example, if there was a substution of a nucleotide in the mRNA codon UAC (which codes for the amino acid Tyrosine) to the nucleotide UAG (which codes for a stop codon).
The translation machinery would reach this codon, which signals that translation should be terminated. This would mean that the mRNA would be released, and a truncated (shortened) version of the amino acid would be produced. This is likely to be non-functional, and may even be marked for destruction by the cell.

There was two of the same question, but here is the answer again with a little more depth.
D - spine alignment and foot size.
It was only the late Australopiths that had an S-shaped spine. This allowed for them to be bipedal, that is, the ability to walk on two legs as we do. This is because the S-shaped spine allowed them to balance when they were standing. The late Australopiths also have shorter and less flexible toes. These smaller, but sturdier feet made pushing off the ground much easier - aiding in their bipedalism.
