Answer:
a. activation of the sympathetic autonomic nervous system by the new experience.
Explanation:
The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.
Answer:
Instrumental learning
Explanation:
Associative learning is a form of learning which is performed when two or more events or stimuli controls the learning behaviour. The instrumental learning is a type of learning in which the learning process is associated with the consequence or result of the action.
In the given question, the mouse learns how to step on the lever as a result of the received food in the form of reward or he learned because he received the treatment, therefore, this act of learning will be considered the instrumental learning.
Thus, Instrumental learning is correct.
Answer:
Explanation:
A cross between plants with round seeds (RR) and plants with wrinkled seeds (rr). If both parents are homozygous, having one type of gamete each, i.e. R from round seed parent and r from wrinkled seed parent (RR X rr).
R R
r Rr Rr
r Rr Rr
All the offspring of generation would be round with genetic constitution Rr. They will be heterozygous plants having two different alleles.
If both parents has heterozygous round seeds with genotype Rr. So, we have Rr × Rr. The gametes produced from each of the parents are of two types, R and r.
R r
R RR Rr
r Rr rr
The generation has a genotypic ratio of 1 RR : 2 Rr : 1 rr. The phenotypic ratio is 3 round : 1 wrinkled.
Answer:The cell cycle has two major phases: interphase and the mitotic phase. During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides.
