False
reason -
Gene testing is not full proof as there are possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof
Answer:
a. food pellet
Explanation:
In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.
In the experiment described above in the question, <em>the unconditioned stimulus is the food pellet,</em> which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.
Answer:
Hypothalamus of human body system interact to perform temperature regulation along with nervous system and endocrine system.
Explanation:
Hypothamus is an important part of our lower brain that play a significant role in regulation of body temperature.
Hypothalamus works with nervous system along with the other parts of our body such as blood vessels,skin and sweat gland to maintain temperature homeostasis of human body.
When our body temperature rises at that time hypothalamus slows down the rate of metabolism of our body to restrict further increase in our body temperature and also dilates the blood vessels present beneath the skin so that body can liberate heat to the environment.
on the other hand when the body temperature decreases at that time hypothalamus increases the metabolic rate of our body to increase the body temperature and also the constrict the blood vessels present under the skin.
Answer:
Fermentation
Explanation:
Fermentation is the process whereby carbohydrates are converted to acohol or acid by the activities of some enzymes. During the process of fermentation, carbon dioxide is produced and it is found as tiny pockets of air inside the bread dough. This make it to rise. The alcohol produced evaporates later during the bread making process.
