Answer:
The correct answer would be option C.
Explanation:
Cellular respiration is the st of the chemical reaction that uses glucose molecule and produces energy as ATP that is the energy currency of the cell. It includes three-stage glycolysis, Krebs cycle and electron transport cycle with an intermediate stage in between Krebs cycle and glycolysis that is oxidative carboxylation.
The energy produced by the cellular respiration is utilized in all type of cellular function including repair and renewal of cell and tissue by the cell division.
Thus, the correct answer is option C.
Answer:
Proteins are the major 'working molecules' within every organism. Among their many jobs, proteins catalyse reactions, transport oxygen and defend organisms from infection- like a doctor for organisms. The precise shape of each protein, and its genes, along with the amino acids it contains, determines what it does, some develop different traits and they may also copy traits of related organisms, which means some organisms may create more protein depending on their traits.
Answer:
There's no eclipse at every full moon and new moon because the moon's orbit is inclined to Earth's orbit by about five degrees. Most of the time, the sun, Earth and moon don't line up precisely enough to cause an eclipse.
Explanation:
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.
Answer:
The correct answer is option c. "Ceruminous glands produce a waxy substance which protects the genitals".
Explanation:
It is incorrect that ceruminous glands produce a waxy substance which protects the genitals. The ceruminous glands are not located in the genital area, ceruminous glands are specialized sudoriferous glands located in the the external auditory canal. A normal ear have between 1,000 and 2,000 ceruminous glands, which produce the ear wax that protects this zone.
Differences.
Exoskeleton
1. Hard part that lies outside of the body
2. Develops from ectoderm
3. Composed mainly of hard non-living material called chitin.
Endoskeleton
1. Hard part that lies inside the body
2. Develops from endoderm
3. Composed of living material i.e. bone tissue
Similarities
Both endoskeleton and exoskeleton play a protective role. The endoskeleton protects internal body organs of the organism. The exoskeleton protects the soft body parts and appendages of the organism.
Both endoskeleton and exoskeleton provide structural support and shape to the concerned organism.
