The answer to your question 12
Interphase: Chromosomes duplicate, and the copies remain attached to each other.
Prophase: In the nucleus, chromosomes condense and become visible. Spindle fibers begin to form.
Prometaphase: The nulcear membrane breaks apart, and the spindle starts to interact with the chromosomes.
Metaphase: The copied chromosomes align in the middle of the spindle.
Anaphase: Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.
Telophase: Nuclear membranes form around each of the two sets of chromosomes, they begin to spread out, and the spindle begins to break down.
Cytokinesis: The two cells split into two daughter cells, each with the same number of chromosomes as the parent cell.
The two major systems involved in the stress response are the Nervous System [the Sympathetic subdivision of the Autonomic Nervous System (ANS)] and the Endocrine System (glands which secrete hormones intonthe bloodstream).
The Endocrine System's response during acute and/or chronic stress (adaptation) involves first the Hypothalamic release of Corticotropin-Releasing Hormone (CRH), which stimulates the Anterior Pituitary (via the blood) to release AdrenoCorticoTropic Hormone (ACTH), which then activates the Adrenal Cortex to release glucocorticoid hormones (i.e. Cortisol), amongst others into the bloodstream. Cortisol then has many effects on tissues and organs throughout the body to allow better generalized coping with the initial stress stimulus.
Answer:
Homeostasis
Explanation:
Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.
An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.
Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.
Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.
Innate behaviors are behaviors that do not need to be taught, you naturally develop them. Some examples are eating and sleeping.
The four learned behaviors: Habituation, Sensitization, Imprinting, and <span>The Conditioned Response.
</span><u>Habituation </u>- Turtle hides into shell after being touched. After being touched several times and has associated that no danger is involved, turtle is no longer scared.
<u>Sensitization</u><u /> - Your first presentation may make you insanely nervous, but once you gain more experience you become less and less nervous.
<u>Imprinting</u><u /> - Ducklings following their mother
<u>Conditioned Response</u><u /> - Dogs don't like getting shots. They may associate the scent or appearance of the animal hospital with getting shots. They may try to avoid the scent or something similar to the hospital.
Hope this helped! :)
