Answer:

Carbon fixation

Explanation:

Ribulose bisphosphate carboxylase (RuBisCo) is an enzyme which catalyses the reaction in which Ribulose bisphosphate (RuBp), a 5 carbon compound reacts with carbon dioxide in the Calvin cycle or light-independent reactions. The reaction results in a 6 carbon compound. In the Calvin cycle, RuBisCo is regenerated from Glycerate-3-phosphate, a three carbon intemediate. In the absence of RuBisCo, fixation of carbon dioxide will not happen, thus carbohydrate will not formed.

Imagine you were going to build a “green” building. What features would it have? What would it look like? How would it harmonize

9966 [12]

Answer:

Green building is a modern concept in architecture by means of which it is aimed at construction developments that are not invasive with the environment, or that affect the ecosystem in which they are built as little as possible, with the aim of leaving future generations an intact environment worth living in.

Thus, for a construction to conform to this concept, it must follow the following parameters:

-The construction must adapt to the natural environment, and not this to the construction.

-It has to be resource-efficient. Furthermore, the materials used must not be exploited indiscriminately or causing damage to the environment.

-The external area of the building must respect the natural patterns of the area where it is built, favoring a harmonic view between the building and the surroundings.

-Use of clean and renewable energy to supply the building.

A team of biologists develop a new drug, and one team member hypothesizes that the drug is incapable of freely passing across th

matrenka [14]

Answer:

B: The drug is a small charged molecule

Explanation:

Substances can passively diffuse in and out of the cell via the cell membrane in two ways;

Simple diffusion
Facilitated diffusion

The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.

In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.

Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.

Correct option: B

Mashcka [7]

Answer:

Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
