The correct answer is option B and C, that is, they do not share similar stimulus characteristics and include a restricted number of stimuli.
An arbitrary stimulus class refers to predecessor stimuli, which induce the similar reaction, however, they do not share relational feature and do not resemble each other in physical form. For example, cheese, peanuts, chicken breasts, and coconut milk are the members of an arbitrary stimulus class if they induce the response, that is, sources of protein.
diffusion is the movement of molecules or stuff through the cell membrane
osmosis is the movement of water
water move from high contration to lower concentration
the there is salt outside of the cells the water will move out of the cell membrane and if there is salt inside the cells the water will move into the cell
Answer: a) true
Explanation:
The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.
The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.
During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.
Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>
Answer:
A feedback loop is a biological occurrence where the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback).
Explanation:
Example, during blood clotting, a cascade of enzymic proteins acitvates each other, leading to the formation of fibrin clot that prevents further blood loss.
