All plants have a cell wall, all mammals have a cell membrane. a cell membrane is semi-permeable it allows mammal cells to absorb needed nutrients, oxygen and deposit waste into the blood stream where it is excreted through urine and feces. a plant cells nutrients are absorbed through the root system and leaves, waste is excreted in the form of oxygen through the plant itself.

What would happen to the possible variation in gametes if the number if chromosome pairs increased from two to three?
Orlov [11]
<span>If each of the pairs of chromosomes was heterozygous (what gives you the highest potential number of different gametes), then the number of possible gametes increases from 4 to 8 for a diploid organism. To figure out how many are possible, raise the number of homologous chromsomes (2 for a diploid organism) to the power of the number of chromosomes. So if you have two different chromosomes (A and B), raise 2 to the 2nd power (or multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C, then you have 2^3, or 2 x 2 x 2 = 8.

To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>

There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.

Oceanic crust is best described as _______.
Valentin [98]
<span>The oceanic crust is part of the crust that is made fully out of basaltic rock and is several times thinner than the continental crust which is made out of granitic rock. Oceanic crust underlies Earth's oceans and is produced at divergent plate boundaries which are commonly referred to as mid-ocean ridges. As it grows from infilling magma and spreads away from the ridges, it will becomes cooler, thicker, and more dense, and will eventually sink into the mantle.</span>
