This drugs taken together are not recommended because it may cause blood pressure to fall
excessively, which can lead to cardiovascular collapse.

headache, heart palpitations, and priapism (prolonged and
painful erection)
According to the phylogenetic tree, Eukarya evolve <u>First in the Prokaryotic Organisms.</u>
Oh god, large question. My eyes hurt... Mitosis is the formation of 2 identical daughter cells (cell division). Mitosis have 5 phrases: interphase, prometaphase, prophase, metaphase, anaphase, telophase and cytokinesis. The chromosomes are duplicated during the cell life just before mitosis since mitosis states that it is the splitting of the cells so duplicating the chromosomes isn't actually mitosis but it is still important to mitosis. Anyway, in interphase, the nucleolus starts to disappear, the microtubule starts to form and the chromosomes start to condense. In pro metaphase, some of the microtubule connect to the centromere, the cell membrane fully disappear and the chromosomes finishes condensing. In metaphase, the chromosomes are pulled to the center of the cell via by the contraction of the spindles and 2 spindles are connected to each of the kinetochores. In anaphase, the chromatids are separated via by the spindles. In Telophase, the nuclear membrane reappears, the chromosomes un-condenses and the micro tubal breaks down. In Cytokinesis, the cell membrane in one cell breaks apart from the other cell forming 2 daughter cells or in plant cells, another cell wall is formed. (this process can differ fro each different organism)
Answer:
Parasites are organisms that infect the body of another living being and live off their hosts to survive. While some parasites create no symptoms in their hosts, others can cause severe illness. Parasitic infections occur when parasites grow, reproduce, or invade organ systems that make their hosts ill.
Answer:
There are four main stages in the water cycle. Evaporation water can go to the clouds from about anywhere that has water ,
condensation the vapor in the cloud turns back to a liquid ,
Precipitation rain ,
and collection water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Most will infiltrate (soak into) the ground and will collect as underground water.
If a step was removed from the cycle then it there would be no water coming down. Let’s say if Precipitation was removed then what would happen. The water would be stuck up into the clouds .
The ice would be melting like it is right know and the polar bear would be going extinct because like off of a show polar bears can’t swim far and for let’s say that someplace would change like the desert would not be so hot.
A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. I think.
