Answer:
Explanation:
Study design:
blood samples from each partner will be collected and sequence for HIV genes. Sequences from other locally circulating HIV strains will be sort for. A phylogenetic tree will be build for easy comprehension
Support for partner-partner transmission:
the strains of the initially infected partner will be nested with the newly infected partner's strains
Refute:
strains different from those carried by the partner would be more closely related to that of newly infected partner's
Answer:
There is a great interaction between reproductive stage and absorption of nutrients.
Explanation:
Good interaction of reproductive stage and absorption of nutrients from the soil is very important for producing good and healthy flowers because reproductive stage needs nutrients. If these nutrients can't available in the soil so the plant produced less flowers and as a result less seeds are produced in the end of this reproductive stage so we can say that reproductive stage and absorption of nutrients has a great interaction between each other.

Answer:
The keystone species is the wolf.
Explanation:
Every species of organism is important to the ecosystem, so if just one species gets extinct for whatever reason there will be consequences for the other species. How big the consequences will be, depends on the species and on how big of an effect it has on the ecosystem. Some species have relatively small importance, while some have huge importance, and the ones that have huge importance are called keystone species.
The keystone species have such big importance to an ecosystem that with their presence everything is under control, but if they go extinct then the ecosystem suffers badly and changes dramatically. In this case, a keystone species is the wolf. The wolves control the elk population, which in turn means that there is no shortage of food for the elk and they don't damage the young trees. By not damaging the young trees, they grow, so there is a much larger area covered by forest. More forest means less erosion, the water of the streams is better controlled, and there is less meandering. If the wolves are out of the picture, as they were for some time, the picture is totally opposite.
Answer:
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
