The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.
Commensalism<span>, in </span>ecology<span>, is a class of relationships between two organisms where one organism benefits from the other without affecting it. This is in contrast with </span>mutualism<span>, in which both organisms benefit from each other, </span>amensalism<span>, where one is harmed while the other is unaffected, and </span>parasitism<span>, where one benefits while the other is harmed.</span>
As an organism evolved an ability or physical characteristic, another organism which evolved the ability to mimic that trait would have a higher chance of survival and could pass on its genes
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
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.
