Which one of the following observations did Darwin first make during his discovery of evolution? a. The ability of individuals t
o survive and reproduce is not equal. b. There is variation in inherited traits. c. Individuals who reproduce more leave more offspring. d. The unequal ability to reproduce leads to the accumulation of favorable traits in a population.
The correct option is (b) There is variation in inherited traits.
Darwin made the following observations that informed his theory of natural selection: Overproduction, Variation, Selection, Survivors.
<h3>What were the darwins observation?</h3>
The first observation is overproduction. This shows that every species has more offspring than will grow up to be adults. Think about all the fish eggs that are produced every year.
This suggests that organisms should constantly reproduce, but they do not because mechanisms like food competition, predators, and disease exist to limit population growth.
Darwin was able to infer from this that there is a struggle for existence.
Darwin's second finding was variation. This suggests that members of the same species exhibit a range of features. For instance, the pattern and color of the stripes on zebras vary. Scales on goldfish might be entirely gold, entirely orange, entirely brown, or a mix of all three.

The correct answer is letter C. Bryophytes have biflagellate gametes and cuticle. The cuticle serves as the covering of the soft tissue of the plant which provides protection and prevents damages on the walls of the plants. The biflagellate gametes develop also as a form of protection as well. These plants have an aquatic ancestry because of their dependence on water for reproduction and survival.

Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere
