<h2>Answer:</h2>
<em>True.</em><em> Yes the sun is the ultimate source of energy.</em>
Explanation:
- We all living organism needs energy for their survival like for walking, talking and breathing.
- Energy is required by every cell for their reproduction, growth and maintenance.
- We all eat food to get that energy. Food is consists of plants and meat of some animal.
- These some animals also get food from plant.
- Plants take sun light to make their food/energy.
- Sun just provide energy in form of food. It dose not get energy from anywhere.
- Hence we all are ultimately depends on sun.
Tachycardia is a condition when the heart rate is greater than 100 beats per min at rest. The electrocardiogram is a diagnostic tool that measures and records the electrical activity of the heart. Bradycardia on the other hand is when the heart rate is slower than normal. The Tachycardia and bradycardia can arise from either the SA node or from other areas of the cardiac.
Answer:
The correct answer is -
1. protein synthesis or central dogma
2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.
Explanation:
1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.
2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.
