The area of the muscle fiber where the actin and myosin myofilaments overlap is
Varvara68 [4.7K]

Answer:

Sarcomere

Explanation:

The muscle fiber / myofibrils consist of 2 types of filaments - actin and myosin. The myosin filaments are thick filament whereas the actin filaments are the thin filament.

In addition to this, the muscles have A-band and I-bands. These bands give the muscles alternate light and dark colour band structure. In the A-band, myosin filaments are present, whereas in the I - band the actin filaments are found.

In I-band 2 Z-lines are located.  The area between the Z-lines is called sarcomere. In this sarcomere region both actin and myosin filaments present.

When muscles get contracted the length of the sarcomere shorten. The actin and myosin filaments overlap in this area. A cross-bridge form between them, with the help of filamentous protein titin.

In a flowering plant, blue flower (B) trait is dominant to white flower (b) trait. A true-breeding blue flower plant (BB) is cro
scoundrel [369]

Answer: D. 100%

Explanation:

One parent is with is a true breeding blue flowering plants this means the two alleles of the genotype are homozygous dominant alleles (BB).

The other parent is a true breeding with flowering plant, this means the two alleles of the genotype are homozygous recessive alleles (BB).

When both parents are crossed, the possible genotype outcome is

B B  *  b b

Bb Bb Bb Bb

Therefore since the blue flowering plant allele (B) is dominant to the white flowering plant allele (b) the probability of an offspring outcome to be a blue flowering plant is 4/4 which is 100%.44

Answer is 100%
