Answer:
15 hours and 40 minutes
Explanation:
The stages of mitosis are prophase, metaphase, anaphase and telophase. Anaphase is the stage of mitosis after metaphase where replicated chromosomes are segregated to opposite poles of the cell. Anaphase is the third stage after prophase and metaphase, which in this case have the same duration (20 minutes each one). In consequence, a cell that is just starting anaphase is 15 hours and 40 minutes old.
Interphase: 15 hours
Prophase: 20 minutes
Metaphase: 20 minutes
This sounds like a question to something your teacher has just recently taught. I'm not sure how he/she wants you to answer but you a welcome to try; caloric intake and exercise frequency. Hope this helped.
Answer:
d.Different sets of genes.
Explanation:
A cell normally only expresses a percentage of its genes and various cell types are created by the expression of distinct gene sets. In addition, in response to changes in their environment, cells can alter the pattern of genes they express, such as signaling from neighboring cells.
In the 1920s, Walter Cannon discovered that emotion-arousing incidents trigger an outpouring of stress hormones from the adrenal glands. One of the stress hormones is Cortisol. Cortisol is a steroid hormone, in the glucocorticoid class of hormones. When used as a medication, it is known as hydrocortisone. It is produced in humans by the zona fasciculata of the adrenal cortex within the adrenal gland. It is released in response to stress<span> and low blood-glucose concentration.
The missing words from your question were </span>stress hormones. I hope this is the answer that you were looking for.
