Falso porque natural selection is actually the process where organisms that are better adapted to their environment tend to produce more offspring than those that have a disadvantage
Diploid cells are like daughter cells coming from a mother cell called a haploid cell. So the more daughter cells are born, the greater the chance of getting hybrids and creating more diversity on the genetic races existing. In this case, the answer would have to be honeybees.
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.
