The correct answer is option A- HIV virus.
HIV virus is an example of enveloped virus, that has the ability to infect a host cell by attaching itself to it and fusing with the host cell.

Answer:
a dam flooding a valley
Explanation:
It would be a dam flooding a valley because in a new ecosystem there would then be a increased load of phosphorus and nitrogen and increased algae growth.
(x-3)² = (x-3)(x-3)
= x² - 3x - 3x + 9
= x² - 6x + 9
The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
<h3>Synthetic theory of Evolution </h3>
- The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.
The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.
Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
