What is the advantage of having a folded inner membrane in the mitochondria

Biology
1 answer:
Aliun [14]3 years ago
8 0

Okay so, the mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.

Hope that helps (:

A marine ecologist counts the number of crabs in three different intertidal regions that are each two hectares. The crab counts
romanna [79]

Answer:

Density is nearly 3 cabs per hectare

Explanation:

Given -

There are three three intertidal regions.

Area of each intertidal region is 2 hectares.

Number of crab in the intertidal regions are as follows -

Intertidal region I - 7

Intertidal region I - 2

Intertidal region I - 6

Sum of crabs in all three regions is equal to

7 + 2+ 6\\= 15

Total area of all three intertidal regions is equal to

2 + 2+ 2\\= 6 hectares

Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions

Density = \frac{15}{6} \\= 2.5

Density is nearly 3 cabs per hectare

Which statement among A-D is false regarding the standard plate count method?
scoundrel [369]

Answer:

The correct answer is option E. "None of A-D is false; all are true statements".

Explanation:

The standard plate count involve different considerations including the ones listed:

A. It utilizes a standard dilution procedure called serial dilution. Most of the time culture plates have thousands of cells growing in it, it is necessary to use a standard dilution in order to make the counting feasible.

B. It measures both live and dead cells in the liquid sample. The standard plate count procedure uses a dye such as crystal violet to differentiate among live and dead cells. Both should be counted and the percentage of viability should be reported as well.

C. A countable plate in the procedure is one having 30 to 300 CFUs on it. Between 30 to 300 CFU is considered a countable plate since less than 30 will be make errors in dilution to be considerable and more than 300 is difficult to count and tend to form cell aggregates.

D. It is a viable count method to quantitate cell density of a liquid sample. This is true as long as the cells in the liquid sample are able to growth in a standard plate as well, since the cells must adhere to the counting device in order to perform the procedure.
