THE STRUCTURE OF THE CELL MEMBRANE
the cell membrane is a thin layer of a partially permable membrane. That protects the cell's organelles and helps to maintain the shape of the cell.
WHAT MATERIALS ENTER OR LEAVE THE CELL MEMBRANE.
since the cell membrane is partially permable, that it only allows some materials to pass through it only nutrients that need to be metabolized or neede by the cell is allowed or permitted to go in the cell either by diffusion or osmosis.
HOW IE ONE METHOD DIFFRENT FROM THE OTHER?
since diffrent materials that go in the cell have different concentrations, sizes, and weights, the method by which they go into the cell will definately be diffrent materials with larger molecules use the osmosis method to go in the cell, while materials with smaller molecules use the diffusion method. I HOPE THIS REALLY HELPED

Why does a parcel of air expand as it rises upward through the atmosphere?
vichka [17]
the atmospheric pressure decreases upwards, hence the inter-molecular attraction between the air molecules decreases or to say that the inter-molecular space increases and the parcel of air expands.

Which statement is not true of endothermic animals?
ahrayia [7]

Hello! Your answer would be C, They regulate body temperature through behavioral mechanisms.

An endothermic animal is one which is capable of maintaining its own body temperature. They do this through physiological mechanisms, which is what the last choice is saying - these involve things such as hormones, sweating, etc.

These endothermic animals are considered warm blooded. This is because they can make their own body heat. Humans and other mammals are endothermic. We generate our own heat - we don't rely on sunbathing or shade to cool down or heat up our <u>internal</u> body temperature.

Hope this helps!

When a living organism dies, it stops taking in new carbon. Thus, as the radioactive carbon-14 decays, the ratio of carbon-12 to
Alexxandr [17]

Answer: The fossil is 11459 years old.

Explanation:

Half-life of carbon-14 = 5700 years

First we have to calculate the rate constant, we use the formula :

k=\frac{0.693}{5700\text{years}}

k=1.21\times 10^{-4}\text{years}^{-1}

Now we have to calculate the age of the sample:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  = 1.21\times 10^{-4}\text{years}^{-1}&#10;t = age of sample  = ?&#10;a = let initial amount of the reactant  = 100 g&#10;x = amount decayed = 75 g&#10;a - x = amount left after decay process  = 100 - 75 = 25 g  Now put all the given values in above equation, we get&#10;[tex]t==\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{25}

t=11459years

The fossil is 11459 years old.
