Answer:
Option A
Explanation:
As per the principle of intrinsic fitness, a person likes to work for his/her inner satisfaction driven by motivation within him/herself.
Thus, a young bird which feels an urge to produce chicks by mating each year will ultimately go outside to find his/her mate on their own and will produce chick every year. In an intrinsic behaviour the rewards achieved are internally self satisfying and thus a person need no assistance in achieving them on their own.
Thus, option A is correct.
Answer: d. breakdown starch
Explanation:
The hydrochloric acid is produced by the parietal cells of the gastric glands present in the stomach. The primary function of the hydrochloric acid is to sterilize the food consumed by the human being. The acidic pH is unsuitable for the survival of the microbes present in the stomach. It triggers the activation of enzyme pepsin which is responsible for denaturation of proteins. The pepsin converts the protein into simple form of amino acids hence, facilitates the digestion of protein content in food.
The starch present in the food is digested by the enzyme called as salivary amylase present in the saliva present inside the mouth. The breakdown and digestion of starch is not the function of the hydrochloric acid.
Answer:
A. The plant would wilt.
Explanation:
In order to stay healthy and fresh, plants like every other living organism require certain substances. One of those substances is WATER, which the plant gets by absorption via the root hairs. The water circulates throughout the plant with the aid of a water-conducting vascular tissue called XYLEM. Without the xylem, water will not be transported throughout the plant.
The xylem tissue helps provide structural support to the plant as it helps the plant cell to be turgid. A non-functional xylem means the conduction of water is impossible, hence causing the plant cells to become flaccid and lose strength; a process called wiltering.

It’s C. The gene for orange and black coat are incomplete dominant and found on different chromosomes; females have 2x chromosomes whereas males have only one X chromosome.
