If you are referring to Darwin's Theory...

1.

Individual show variation

2.

Variations can be inherited

3.

Organisms produce more offspring then can survive

4.

Hope this helps, (:

Glycolysis occurs in the mitochondria protoplasm cytoplasm of the cell.

dmitriy555 [2]

Glycolysis occurs in the cytoplasm of the cell. You can remember this because even prokaryotic cells can do glycolysis so it must occur without a membrane bound organelle such as a mitochondrion.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

What two characteristics do fungi lack that forced them to become decomposers

Artist 52 [7]

Fungi are decomposers, they obtain their food from dead organic matters. Fungi obtain their nutrient this way because they can not produce their own food. To produce their own food they need chloroplast in their cells to obtain energy from the sun. And they also need the ability to fix nitrogen which they will incorporate into the food they produce. Because they lack the ability to do this thing, they have to adapt to eating dead materials. <span />
