What gives a cell structure and provides support for its internal organelles

Sergio039 [100]

The cell's structure is given by the cytoskeleton found in the cytoplasm of cells. The cytoskeleton is made up of complex fibers throughout the cell that was discovered after a second glance at cell with improved microscope technology. It serves the same purpose as bones and muscles in the body, aka, it forms shape, keeps organelles in place and directs movements of organelles.

These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. W

Lana71 [14]

The correct answer is B. S-curve

Explanation

There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about

Bogdan [553]

Answer:

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

Explanation

Energy can be calculated by the equation

Q = m x Cp x delta T

where

m = mass = 0.5 kg

Cp = specific heat of water = 4184 J

Delta T = 12 degrees

Multiplying all

Q = 0.5 x 4184 x 12 = 25104 Joules

Converting it to Calories

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.
