Assume that you have an illuminated suspension of Chlorella cells carrying out photosynthesis in the presence of 0.1% carbon dio

xide and 20% oxygen.
What will be the short-term effects of the following changes in conditions on the levels of 3-phosphoglycerate (PGA) and ribulose-1,5-bisphosphate (RuBP)?

Carbon dioxide concentration is suddenly reduced 1000-fold.

a. PGA down, RuBP up
b. PGA up, RuBP down
c. PGA up, RuBP unchanged
d. PGA unchanged, RuBP up

Answer:

a. PGA down, RuBP up

Explanation:

RuBP, also known as Ribulose-1,5-bisphosphate is a molecule that assist in he fixation of carbon dioxide in the Calvin Cycle or light independent reaction of photosynthesis.

RuBP is combined with carbon dioxide using the enzyme known as rubisco to form an short-lived intermediate product which divides to form two 3-carbon molecule structure known as 3-phosphoglycerate.

<em>If the concentration of carbon dioxide is suddenly reduced, it thus means that the rate of production of 3-phosphoglycerate will reduce as carbon dioxide becomes a limiting factor. Hence, 3-phosphoglycerate's  concentration will reduce while more RuBP will become available as a result.</em>

The correct option is a.

Describe how biogeographical studies, esp. of islands and continents, explain species similarities and differences
Elan Coil [88]
Biogeographical studies use information for various fields, such as evolutionary biology, geography, geology, and climate science to determine how organisms evolved through time and how the moving of tectonic plates resulting in forming continents, mountain ranges and islands has affected their distribution.
Studies in this field explain how organisms that now live on different continents are very closely related and how the flora and fauna of islands are connected to one of the closest continents etc.

What should a person eat if she wants the fastest supply of energy?
Paul [167]


A person should eat energy bars and they should eat energy drinks because it supplies a good amount of carbohydrates (sugar) that can quickly convert inside your body to energy.

(Some good examples of energy drinks would be the brand 'Gatorade')

I am not so sure what exact brand of energy bars to eat, but I know for a fact that each energy bar contains carbohydrates, so probably any energy bar would work. :)

ICE Princess25 [194]

Answer:

Reduce genetic diversity

Explanation:

Genetic diversity is an extremely important factor when it comes to evolution. The more diversity and variation there is within a population, the more chances a species has of surviving.

In the case of inbreeding, organisms that are related are selected to mate. This has extremely negative effects on the species such as bad health and infertility issues. In addition, because they all share the same alleles, it results in a decrease in genetic diversity, augmenting the chances of the species to disappear.

This occurs because if, for example, there is an organism that possesses a capability to resist extreme weather conditions and another that does not have this trait, there are still chances to survive, whereas if they are all the same and none of them possess this capability, the probability of this species to go extinct is higher.
