To determine how long it takes a solution containing algae and the indicator to turn blue under different intensities of light. Option B.

<h3>Photosynthesis</h3>

During photosynthesis, green plants use their green pigments to absorb light and drive the reaction between carbon dioxide and water to produce carbohydrates. The equation is as below:

$6CO_2 + 6H_2O --- > C_6H_1_2O_6 + 6O_2$

Thus, in the experimental setup, the algae will gradually consume CO₂ to produce carbohydrates.

Since bromothymol blue turns blue from yellow when CO₂ is removed from a solution, its function in the setup would be to indicate when all the CO₂ has been consumed by the algae.

zalisa [80]

The space between the parietal layer and visceral layer of the pericardium contains serous fluid. It is a tissue of the hearth.

<h3>What is pericardium?</h3>

The pericardium is one of the three tissues that form the hearth, which also includes the myocardium and epicardium.

The pericardium forms a highly fibrous structure that is capable of holding heart tissues and blood vessels.

Pericardial fluid is composed of a serous liquid that is produced by the pericardium and released into the pericardial cavity.

Which kingdom would include organisms that are all heterotrophic and motile?

zlopas [31]

Answer:

Animalia, essentially

Explanation:

First, let's define our terms -

<u>Heterotrophic</u>: consumes other organisms to survive, as opposed to <em>autotrophic</em>

<u>Motile</u>: can move around, as opposed to <em>sessile</em>

There is debate on what constitutes a kingdom, but I generally go with the 6 kingdoms model, which includes animalia, plantae, fungi, protista, eubacteria, and archaebacteria.

Fungi, though heterotrophic, include mushrooms, which are obviously stationary (sessile). So we can rule them out.

Plantae are your traditional plants, which clearly fit neither of the categories, being sessile and phototrophic (they get energy from light, not other organisms.)

Archaebacteria are mostly autotrophs. I doubt they would be considered anyway.

Eubacteria, your traditional bacteria, include cyanobacteria, which are photosynthetic, and other exceptions. I don't think this is what the question is going for.

Protista are essentially the spare parts drawer of the kingdom system. They vary widely in being hetero- or autotrophic, so they certainly don't fit the criteria.

I can only conclude that this question is asking for animalia, which <em>for the most part </em>are heterotrophic and motile. (An exception is the most primitive, sponges or porifera, which are sessile and can't move around, but I expect this is what the question is looking for.) Because heterotrophy and motility are two defining features of animalia, most likely this is what the question is asking. This is a difficult question, because biologists themselves aren't real decided on the right answer.

how does the nucleus contribute to the transcription and translation of genetic information into proteins.

Bumek [7]

Answer:

transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA in the cell nucleus. A type of RNA called transfer RNA also known as tRNA assembles the protein, one amino acid at a time.
