Viefleur [7K]

When one thing dies, or is taken away from the food web, then this could happen:

Let's say plants are taken away. Then, herbivores have nothing to eat, sot hey die. Then, carnivores have nothing to eat, and the same thing happens, etc.

Plants are the base of survival for every organism in nearly every ecosystem.

Describe how the functional units for beta carotene, xanthophyll, chlorophyll a, and chlorophyll b are different. be sure to ide
leonid [27]

The pigments have a similar structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls, hence move farthest in chromatography paper using a nonpolar mobile phase. Chlorophyll pigment, on the other hand, has chlorin rings (which are larger) as functional units hence move slowly in chromatography.

Photosynthetic rates can be measured by either the amount of oxygen they consume per particular time period or the amount of carbon dioxide produced per particular time period. This is conducted while immersed in water so as to measure bubble rate formation in case of oxygen production or the change in water pH in the case of carbon dioxide consumption.

When autumn approaches, the amount sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing chlorophyll a and b pigments (most important in photosynthesis) during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from green to yellow-red.

It is believed that this is the result of an ancient endosymbiotic relationship between a protist and a eukaryotic cell. The protist generates energy that the eukaryotic can utilize in its growth and reproduction while the protist is sheltered. This relationship became obligatory symbiosis over time.

How might giving a mumps vaccine to a boy protect his reproductive health later?
ArbitrLikvidat [17]
<span>There are a small number of boys who, after possibly contracting mumps, could experienced decreased fertility in the future. Giving a mumps vaccine, since it's a weaker version of the virus, will allow the body to fight it off without the negative effects that could come with a full version of the illness.</span>
