B. anisogamous
C. oogamous
D. none of the above
Human gametes are anisogamous, which means the reproductive cells are different in size. The male gamete, sperm, is smaller and motile while the female gamete, ovum, is larger and non-motile.
Human gametes are B. anisogamous. The term 'anisogamous' means that the gametes or the reproductive cells are different in size. In human beings, the male gamete, or sperm, is smaller and motile, while the female gamete, or ovum, is larger and non-motile. This is a typical characteristic of sexually reproducing species where there are distinct male and female gametes. Isogamous refers to species where the gametes are of equivalent size and morphology, and oogamous pertains to species where a tiny, motile sperm fertilizes a large, stationary ovum, which is primarily in many algae and fungi. So, among the given choices, human beings fall under the category of anisogamous.

Explanation:
Because these fossils would have had no way to get across the ocean, especially for large terrestrial animals. The continents used to be in different locations, allowing some animals to cross. These animals then died on different continents as they shifted, thereby proving that the continents used to be much closer than they are now.
Answer:
This is not true
Explanation:
Wells were used in olden days to store and use water. During those days mechanical pulleys were used to extract water out of wells but now a days modern pumps and lifting equipment are used for bringing underground water to the users.
These days water is supplied through pipes and no traditional bucket or rope is used for pulling out water out of the ground. Though wells exists even today but its usage as a primary source of fresh drinking water is no longer in system but rather they are preferred as water storage units.

The use of wells to obtain drinking water is not a modern convenience. It might have been a convenience in the past, but with our technological advancements, the use of wells aren't that popular anymore. It is not disregarded though that the usage of wells aren't dropping to a stop since they are still utilized by people usually living in the rural areas. As for the convenience part, well it isn't as convenient as it seems since establishing the well itself would take so much work.

B. Uneven rock layer
C. Climate change
D. Erosion
b. the plant flower opening with the sunrise
c. the plant root growing down into the soil
d. the plant turning towards the sun
Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
