Answer:
The stages of human life can be written as:
- Infancy: It is the time period between birth and the age of one year.
- Toddlers: It represents the child between 1 to 3 years of age.
- Childhood: Children between the age group of 4 to 8 years old are referred to being in childhood.
- Puberty: It is the time period in which children mature sexually. It represents the children which are 9 to 13 years old.
- Adolescents: These are also termed as teens as the age bracket is thirteen to eighteen years old.
- Adulthood: The age range from 19 to 50 years.
- Old age: It represents the people which are 51 plus in age.
Growth Hormone and insulin are protein hormones that promotes the growth and regulation of substrate metabolism.
Explanation:
The Growth Hormone performs the metabolic actions in various tissues like liver, muscle, and pancreas through insulin growth factor. Insulin slows down the growth hormone signalling through the growth hormone receptor. It is important for maintaining the responsiveness of liver to growth hormone.
The insulin signalling pathway is very important in metabolic diseases like diabetes and aging. These insulin activates a phosphorylation cascade that branches to form a network affecting multiple biological processes.
<span>Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
</span>The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite <span>receive nerve impulses from other cells. </span><span>The place where the axon of one neuron meets the </span>dendrite<span> of another is called a </span>synapse.
Light-headedness is a condition in
which an individual may feel dizzy or about to faint and it often goes away or
improves when one lies down. For the question above, you should respond by
having your coworker sit down in a cool area, and drink plenty of cold water.
Answer:1.c 2.d 3. d
Explanation:
The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.
The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.
