Answer:
The skeletal system provides the shape and form for our bodies in addition to supporting and protecting our bodies, allowing bodily movement, producing blood cells, and storing minerals. This system consists of bones, cartilage, and joints.
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs.
Answer:
The correct answer will be option-B
Explanation:
Meissner corpuscles are one of four types of mechanoreceptors which response to mechanical pressure.
The corpuscles are very adaptive and sensitive receptors which convert the stimuli to action potential and send them to the Central nervous system.
The corpuscles are found in the areas which are exposed to touch or are sensitive to touch like in the fingers of the hand and the lips.
Since the deaf and blind lady distinguishes people with a light touch, therefore, these Meissner corpuscles are involved in helping identify the individuals.
Thus, Option-B is the correct answer.
Answer:
Cell will not replicate because of incomplete DNA replication.
Explanation:
DNA replication is crucial for reproduction/replication of any organism as it involves the duplication of genetic material. So if an organism is unable to perform proper DNA replication it would not be able to reproduce.
DNA polymerase is the enzyme that synthesize the new DNA strand in DNA replication. DNA polymerase can synthesize a strand only in 5'→3' direction. Both of the strands of DNA molecules are opposite in direction. So one strand is synthesized continuously called as leading strand while the other strand is synthesized in form of okazaki fragments called as lagging strand.
The okazaki fragments are joined together by the enzyme ligase. So if Ligase enzyme is absent in bacteria it would not be able to synthesize the lagging strand of DNA and thus could not be able to produce a replica of DNA. And if there is No replication of DNA then No replication of cell would occur.
Answer:
50 grams and 175 grams
Explanation
Acceptable macronutrient distribution range are predetermined ranges of intake of a specific macronutrient such as Proteins, carbohydrates and fats.
It was developed to promote healthy diet in the society.
According to the AMDR, the ranges of proteins should be 10-35 percent of the calories.
Therefore;
10/100×2000=200
But 1g contains 4 kilocalories of protein so;
200kCal/4kcal=<u>50 grams</u>
<u>35/100×2000=700 kcal of protein so; </u>
<u>700kcal÷4kcal= 175 grams </u>
