Answer:

False.

Explanation:

Bacteria are the prokaryotic organism that lacks the well developed nucleus and the membrane bound cell organelle. The animal cells are the eukaryotic organisms.

Bacteria cells have cell walls that are made of the peptidoglycan layer. The cell wall of bacteria are important as it protect themselves from the extreme environment. The animal cells do not contain cell wall and they have plasma membrane only in their structure.

Thus, the correct answer is option (b).

Fantom [35]

Answer:

Explanation:

A woman with type A blood (whose father was type O) meaning her genotype is AO mates with

Man that has type O blood (OO genotype)

Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.

Cross

A O M N H h

O AO OO M MM MN H HH Hh

O AO OO N MN NN h Hh hh

Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4

Type A with M antigen:

1/2*1/4*3/4 = 3/32

Type A with M and N antigens:

1/2*1/2*3/4 = 3/16

Type A with N antigen:

1/2*1/4*3/4 = 3/32

Type O with M antigen:

1/2*1/4*3/4= 3/32

Type O with M and N antigens:

1/2*1/2*3/4 = 3/16

Type O with N antigen:

1/2*1/4*3/4 = 3/32.

The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).

Does the color of a surface affect its temperature
lubasha [3.4K]
 light is a form of energy expression, so knowing the law about energy conservation, we can conclude that the light absorbed by the dark object doesn't disappear but turned into heat, which is kept or emitted by the dark object.


So Yes,
the darker the color, the better the heat radiation is
