Answer:
The living conditions were unfair. People owning big industries saw an opportunity to work these immigrants day and night, though they only paid them less then what they deserve (but they didn't know that because they are new to America). Immigrants often didn't have enough money to provide for their families, so many of them were split apart and some children had to work. Because most couldn't pay for housing, many immigrants from the same areas lived in groups so they could help support each other. It was a difficult time for many, and a lot of immigrant workers slept in the factories, for there was no else to go.

Homeotic genes regulate the development of structures. Logically, then, the mutation of this gene must result in improper structure development, such as structures in abnormal places. The answer is C.
<u>During </u><u>latent </u><u>phase of a muscle twitch chemical changes such as the release of calicum are according intracelluary as rthe muscles prepare for contractrion.</u>
What are the phases of a twitch contraction?
- A single contraction is called a twitch. A muscle twitch has a latent period, a contraction phase, and a relaxation phase.
- A graded muscle response allows variation in muscle tension.
What is a latent period ?
The amount of time that passes between an action potential being generated in a muscle cell and the beginning of muscular contraction.
What is a muscle twitch?
- The fundamental reaction of a motor unit to a single stimulus is a muscle twitch. Muscle Twitch in three different states .
- Excitation of the muscle fiber takes place during the latent phase, and calcium ions are released from the sarcoplasmic reticulum into the cell's cytoplasm.
What happens during latent period of muscle twitch?
- A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase.
- The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle.

The chromosomes become more compact and tightly coiled. They are ready to separate. :)
