Lady bird [3.3K]

Answer:

Tissue

Explanation:

A cell is a structure formed during the evolution which contained all the molecules and favourable conditions required to survive and therefore acts as the functional and structural unit of life.

In evolution, more than one cell aggregated together to form a structure which could perform much complex function than a single cell called tissue as they are programmed to perform the same function.

In the given question, since the heart cells worked together to cause movement in the robot therefore the cardiac cells formed cardiac tissue or heart.

Thus, the tissue is the correct answer.

A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozy
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).
