Answer:
Explanation:
There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be:
The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.
They swam to the other continent/s in breeding pairs to establish a second population.
Answer:
This question is asking to identify the molecule being described.
The molecule is GLUCOSE
Explanation:
Photosynthesis is the process by which green plants make their food using energy from sunlight. This food, which happens to be the product of the photosynthetic process is GLUCOSE molecule. Glucose is the source of energy during cellular respiration for plants and animals as it is broken down to synthesize ATP.
The process of cellular respiration, which is carried out by virtually all living organisms make use of the GLUCOSE MOLECULE. The energy stored in the glucose molecule is converted to ATP in the mitochondria.
One of the most intelligent invertebrate animal is the octopus. These animals belong to the cephalopod class of molluscs. These animals demonstrate relatively complex reasoning especially when capturing prey. They also demonstrate their intelligence by their communicating skills and some even show signs of learning.
Answer:
Option (2).
Explanation:
Zygote is formed by the fusion of the male and female gamete during the process of sexual reproduction. The zygote undergoes further development inside the female womb.
The embryonic period starts from the third week after the conception. The important organs and structure development occur during the embryonic period. The formation of three germ layers occur in this period.
Thus, the correct answer is option (2)
