The skeletal muscle is used, so A.
Answer:
hypertrophy
Explanation:
Hypertrophy is the excess enlargement of a tissue. When a tissue or organ overgrow without any cell division, it is called hypertrophy. For example, muscular hypertrophy occurs when there is a very forceful and repetitive muscular activity as it occurs during strength training. It triggers enlargement of muscle fibers as myofibrils, mitochondria, and other organelles are produced more in number to support the excess workload of the muscles.
Option A is correct. After making a punnet square, we can see that the genotypic ratio would be 1:2:1, being 25% dominant, 25% recessive and 50% heterozygous. However, we are asked for the phenotypic trait percentage. The phenotypic ration is 3:1, with 75% polka dotted tail (dominant gene active) and 25% solid tail (recessive gene active).
Pls thanks + branliest :P
It has the potential to add new traits to future generations of a specific species (hopefully good ones) but it could also impact that species in a negative way and decimate the species, because mother nature is a significantly better genetic engineer then we will ever be and we don't always know exactly what the indirect impacts of the new genetic "advantages" we implement will be.
Answer:
A nail grows from a deep layer of living epidermal tissues, called the nail matrix, at the proximal end of the nail. Stem cells in the nail matrix keep dividing to allow nail growth, forming first the nail root and then the nail plate as the nail continues to grow longer and emerges from the epidermis
Hope this helps
