Answer:
It is confirmed that epigenetic changes play a significant role in imprinting disorders and food like folic acid, vitamin B12 and other certain food can affect the DNA methylation process.
Demethylation of DNA has been effective to human disorders even though methylation is an important and natural process, may be useful for regulating one gene which can lead to various changes that need to be avoided.
Answer:
A
Explanation:
Living organisms adapt to their moves and positions in response to the environmental changes for their protection or to their advantage. When an entity reacts to the changes in its surroundings, it is referred to as stimulus while the reaction to the stimulus is referred to as a response. Common stimuli are sound, light, air, heat, smell, taste, water and gravity.
Think of burning your finger of fracturing your bone without any pain sensation. It may certainly sound like a superpower or an ideal situation, however, when it comes to the standpoint of survival, it can be disastrous.
It is a characteristic behaviour of living entities to respond to stimuli with the intervention of the Nervous System. It is an organ system ascribed to send signals from the spinal cord and the brain throughout the body and then back from all the body parts to the brain. Neuron acts as the mediator and is the basic signalling unit of the Nervous system.
Pain is the body’s way of letting us know that something is not right. It can prevent further injuries or push us to seek medical attention. Moreover, all of this is possible because humans can respond and react to stimuli due to control and coordination among the various organs and organ systems.
Control and Coordination in simple multicellular organisms take place through only the Nervous system which coordinates activities of our body. It is the control system for all our actions, thinking, and behaviour.
<u>Answer</u>: Dense regular (fibrous) connective tissue.
<u>Explanation</u>:
- <em>Connective tissue</em> is a tissue that performs various functions such as binding, connecting and supporting the other organs or tissues or separating one tissue from another.
- <em>Dense regular connective tissue</em> connects various tissues present in the body.
- Since the fibers are tightly <em>packed</em>, this tissue is <em>dense and fibrous</em>, and because the arrangement of the fibers is in <em>parallel</em> fashion, it is of the <em>regular</em> type.
