When the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.

What is Earth rotation?

Earth's rotation or Earth's spin is defined as the rotation of the planet Earth around its axis as well as the change in the orientation of the axis of rotation in space. When viewed from Polaris, the north pole star, the Earth rotates in the east facing east, the Earth rotates counterclockwise.

When the heading of the particular place is towards the Sun, there is warm temperature which is called as the summer when the heading of the same place is away from the Sun, there is cold temperature which is called as the winter.

Thus, when the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.

Secondary Consumer organism that consumes a primary consumer for energy.Tertiary Consumer organism that consumes a secondary consumer for energy. Therefore options "B" and "A" are correct.

What are primary and secondary producers?

Primary producers are known as autotrophs. They generate energy from the sunlight. The process by which they produce energy is known as photosynthesis. Examples of organisms are algae, bacteria, higher plants, and some protists. These organisms also store this energy.

Secondary producers are the organisms and animals which feed on the primary producers. After consumption, they convert it into energy. The energy generated is known as ATP. The process by which the energy is generated is known as cellular respiration.

C

Answers

Answer:

C

Similar fossils are found on the coasts of South America and Africa.

Continental drift is a hypothetical argument that affirms that the continents of the Earth shifted over the geological timeline. It says that the landmasses drifted over the oceans hence creating several continents and oceans.

The correct answer is:

Option C. Similar fossils are found on the coasts of South America and Africa.

The explanation for the correct answer is:

The continents either drifted away or clashed together to form present-day continents.

Remains from similar species infer that South America and Africa used to be together.

The theory of Pangaea states that all the continents were united once but due to a shift in tectonic plates the continents drifted apart.

Therefore, alike fossils found in various continents supports the theory of continental drift.

Which of the following observations would provide the strongest evidence that two plants belong to different biological species?

A. There are variations in their RNA sequences.

B. The leaves and flowers show morphological differences.

C.They produce viable but sterile offspring.

D.They occupy unique habitats in an ecosystem. .

Answers

Answer:

the answer is C

Explanation:

Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.

The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).

The biological concept of species was developed by Ernst Mayr, who also develop the idea that species are metapopulation lineages.

The biological concept of species states that mating between individuals of the same species produces viable offspring.

The biological concept of species can be used to provide independent evidence for the presence of morphological and biological species.

In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
