<span>Damming a river has a variety of effects on the freshwater ecosystem, more than just altering the flow from A to B. Dams create calm bodies of water, changing overall temperature regimes and sediment transport, leading to conditions which tend to favour generalist species. Loss of specialist species, particularly endemics, changes the community structure and leads to biotic homogenization. A dam will withhold sediment in the reservoir, not just decreasing the amount of substrate available to local freshwater species, but even impacting diadromous, estuarine and marine species much further downstream. The competition between resident species for food and breeding sites will increase as damming isolates populations, and perhaps more importantly, damming completely restricts migratory fish species. Isolation may lead to decreases in genetic diversity and therefore puts species at greater risk from disease. All of these effects may be exacerbated by changes in the surrounding land use. Overall, damming river flow will lead to both a loss of native species, but also an increase in exotic species which are more likely to become established in degraded habitats. For this reason, dams are one of the greatest global threats to freshwater biodiversity.</span>
Because proteins are complex molecules, the body takes longer to break them down
The answer is Urine specific gravity less than 1.025. Because
the exact gravity is less than 1.025 after treatment, the outcome is measured
positive. In syndrome of unsuitable antidiuretic hormone (SIADH), the specific
gravity is greater than 1.025. Small cell lung cancer is a risk factor of SIADH.
<span><u>Mitosis </u>
</span><span><span>
Mitosis </span>and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. </span>
Answer: C
Explanation:
HIV is classified as a retrovirus because its genetic material is composed of single-stranded RNA nucleotide. And also Retroviruses have the enzyme reverse transcriptase, which is capable of making a DNA copy of its RNA once inside the infected host cell
