the 5-to-3 direction of one strand is counter to the 5-to-3 direction of the other strand.
<h2>Respiration is a <u>
redox</u> reaction where sugar is oxidized to produce energy.</h2>
Explanation:
Respiration is a biochemical process that involves a series of reactions most of which are redox reactions to produce energy by oxidizing sugars.
It involves the breakdown of glucose (glycolysis) in the cellular mitochondria to produce ATP which is the fundamental unit of energy in the human body
Answer:
It tells us that homologous structure is evidence of common ancestry
Explanation:
<em>Homology is the similarity of organs of different organisms even though they perform different functions in the organisms. Organs that are built on a similar plan but perform different functions are known as homologous organs. </em>
Organisms having organs built on a similar plan is an indication that they were once from the same source and adapting to different environments must have been the reason the organs evolved for different functions.
For example, all mammals have limbs that are built on a similar five-digit plan even though limbs are adapted for different functions in different mammals.
6. Algae are biotic factors. They are living organisms which have the capability to produce food through photosynthesis. It acts as a producer. Also they appear on the wall of tank through reproduction , which is characteristics of living being.
7. Snail is also a biotic factor like algae. They are classified as consumers. They feed on algae to survive with in the tank. They move while feeding on algae and movement is an important trait of living being.
8. Light Bulb is an abiotic factor. Though it is an essential requirement for fish to survive but since it is not a living being , it is considered as abiotic. While fish on the other hand is a biotic factor as it possess life in it.
