Answer:

Yes, a plant can reproduce without another plant involved.

No, there is no beginning of rock cycle.

Two ways in which carbon dioxide is released into the atmosphere are burning of fossil fuels such as petrol and coal etc and respiration process.

Explanation:

This type of reproduction occurs in non seed bearing plants such as ferns and mosses etc. These plants reproduce by the formation of spores. Spore formation is a type of asexual reproduction in which only one plant is involved. In cellular respiration, glucose molecule is broken down and energy is released with carbon dioxide gas. Fossil fuels are also responsible for the emission of carbon dioxide gas after burning in vehicles and industries.

In the equation above, m is a constant. If the equation has the solutions x=−5/2 and
x=3/2, what is the value of m?
-m (3/2) + 9 = 0
-3/2m +9-9 = 0-9
-3/2m = -9
(-3/2m)(-2/3) = -9 (-2/3)
m = 6

Explain how science uses fossil evidence to support the theory of evolution
Oksi-84 [34.3K]

Answer:

The fossil record

Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. 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.
