Vladimir79 [104]3 years ago
7 0

Answer:

A. contains the cell's DNA

Explanation:

Prokaryotic cells such as the bacterial cells and the cells of archaeans do not have a membrane-bound nucleus. Their genetic material DNA is present in the cytoplasm only. However, their genetic material is concentrated in a specific region inside their cells. This is called a nucleoid. Nucleoid does not have any surrounding membrane. It represents the nuclear area where the DNA of the prokaryotic cells is present.

If resaurchers use only the number of coral found in dive 1 calculate the predicted population of brain coral in a reef that cov
Aloiza [94]

Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40

First step : Calculate the value of the default population density

Population density = population size (dive 1) / total area

                                                               = 4 / 12  = 0.33

Total area ;

∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²

∴ Total area = 4 + 4 + 4 = 12m².

Final step : Determine the value of the predicted population of brain coral

Population density = ( predicted population ) / predicted area

0.33 = ( pp ) / 120m²

∴ Predicted population ( pp ) = 0.33 * 120

                                                = 39.6 ≈ 40 brain corals

Hence we can conclude that the predicted population of brain coral is 40

Marta_Voda [28]

Answer:

<em>When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power.</em>

Which of the following transport mechanisms utilizes energy? A) osmosis B) Diffusion Facilitated difusion D) endocytosis
prisoha [69]
D) Endocytosis is a transport mechanism that utilizes energy.
Endocytosis is an active transport, a biological process in which <span>molecules from outside the cell (proteins for example) are passed through the cell membrane and put into the cell. This process requires energy.

The other transport mechanisms, osmosis, diffusion and facilitated diffusion are processes that do not utilize energy. </span>
