The fossil record
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
Answer:
Life, water, huge population of living organisms, biodiversity of species.
Explanation:
Earth is the only planet in our solar system that can maintain living organisms. It is the only planet in our solar system that is suitable for humans and animals to live on. Only planet with water suitable for a human/animal to drink. Many different types of species and organisms live on earth. And there is a large amount of living organisms living on earth.
Hope this helps!
From the options given above, the two structures that will provide positive identification of a plant cell under a microscope are CHLOROPLAST AND LARGE CENTRAL VACUOLES.
Plant cells have some cell organelles which is unique to them, these organelles are not found in animal cells. Examples of such organelles are chloroplasts, large central vacuole, cell wall, etc. The chloroplast found in plant cells help the plants to trap energy from the sun during the process of photosynthesis. The large central vacuole found in plants play a critical role in turgor pressure of plants.
<h3><u>Answer;</u></h3>
- mid-ocean ridges,
- abyssal plains,
- trenches,
<h3><u>
Explanation</u>;</h3>
- <u>Ocean basins refer to the part of the surface of the earth which extends to the sea from the continental margins.</u>
- All ocean basins are characterized by the primary features such as; <em><u>mid-ocean ridges, abyssal plains, trenches, and seamounts.
</u></em>
- Mid-ocean ridges are the most impressive feature of all ocean basins, which are long-continuous volcanic mountain ridges, they mark areas where oceanic crust sections are pulling or stretching apart.
