A section of elodea leaf is stained and examined under a microscope. The total number of cells in each stage of the cell cycle i

s recorded and presented in the table. If the complete cell cycle in an elodea leaf requires 24 hours, what is the average duration of metaphase in the cycle? assume no cells are in go.

Answer:

(Cells in metaphase/total number of cells) x 24 hours = hours in metaphase

Explanation:

You need to find the proportion of the cells in metaphase to the total number of cells, and multiplying by 24 hours will then give you the number of hours spent in metaphase.

For a more concrete example:

11 metaphase/200 total = .055

.055 x 24 hours = 1.32 hours in metaphase

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cel
Leviafan [203]

Answer:

large central vacuole

cell wall

Explanation:

Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.

Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.

A mixture of oxygen, hydrogen, and nitrogen exerts a total pressure of 378 kPa. If the partial pressures of oxygen and hydrogen
NARA [144]

As we know that

<span>P total = pO +pH +pN</span>

<span>so</span>

P = P1 + P2 + P3

378 kPa= 212 kPa + 101 kPa + P(H2)

P(H2) = 65 kPa

partial pressure is 65

so correct option is A
