Answer:
C. Genetic material composed of nucleic acid
Explanation:
The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.
The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
Answer:
C: competitive exclusion
Explanation:
<em>The competitive exclusion principle states that organisms living in the same community while competing for the same resources cannot coexist at a constant population rate. </em>
Once some of the species within the community get a slight competitive edge over other species, they become dominant and this might lead to the extinction of the weaker species in the long run.
<u>In the experimental plot, the removal of sea stars provided mussel and barnacle with a competitive advantage over other species within the community (sea stars are predators of mussels and barnacles). This led to the dominance of mussel and barnacle and the eventual extinction of other species within the experimental plot as compared to the control plot.</u>
The correct answer is C.
Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. ... Invasive species can change the food web in an ecosystem by destroying or replacing native food sources.

Answer:
2-Water helps maintain body temperature.
3-Diuretics like alcohol and some medications can cause the body to lose water.
Explanation:
Dehydration occurs when the amount of what loss is more than the amount taken. And we lose water in many ways therefore taking water on a regular basis is important to replace the fluids lost and keep the body functioning.
Water Maintains the Body Temperature
During high temperature, the body cools itself naturally by sweating and by sweating a large amount of water is lost. So when enough water is not taken, there will be less production of sweating thereby causing the body's temperature to rise.
Alcohol Causes Water Loss
Taking excess alcohol can result to dehydration because the hormone called anti-diuretic (while alcohol is diuretic) is used to reabsorb water by the body and alcohol in the body depletes the production of this hormone. The body loses more water than normal with a reduced amount of anti-diuretic in the body. Excessive intake of alcohol can also cause vomiting, which depletes the body of fluids and can cause further dehydration.
