Mutated gene
A mistake by cellular machinery, or damage from an environmental agent such as radiation may produce a mutated gene which is a permanently altered segment of dna.
A gene mutation is a perpetual change in the DNA sequence that forms a gene which makes the sequence different from what is present in most people. Gene mutations can be classified into; hereditary mutation (changes inherited from parents) and somatic mutation (changes caused by environmental factors such as ultraviolet radiation from the sun).
Answer:
B. found in every living thing
Explanation:
Answer: Gastrocnemius, soleus, and Achilles tendon
Explanation:
The heel cord or achilles tendon is also known as calcaneal tendon is found at the back of the leg and is known to be the thickest bone in the human body.
It is attached to the plantaris, calf muscles (gastrocnemius) and soleus muscles. A person who wears heels regularly for a longer period of time suffers from pain and inflammation in muscles of leg.
These muscles helps in the walking and other movements of the legs. Wearing heals and walking is quite painful.
<h2>
Answer</h2>
It is because of different arrangements of nucleotide bases.
<h2>
Explanation</h2>
There are only five types of nucleotide basis are present in the genetic material which makes up the all the genetic information of the individuals. These nucleotides are named as Adenine, Thymine, Guanine, Cytosine and Uracil. In all the living beings on the earth, these only five nucleotides are present which decides their behaviour and functions on the earth. These five bases have features to get any arrangements according to the situation. Their different arrangement at the heredity material makes the difference in all living beings regarding their behaviour.
Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
