Answer:
It is true that one-toed horse of today steadily evolved from its five-toed ancestor.
Explanation:
- Evolution is the law of nature.There is a continuous process of evolution in each biological species in nature.
- Similarly, horses had 5 toes millions of year back, but according to the theory of gradualism their use decreased and toes started fusing.
- Now, its only one toe at present but the vestigial left over provides the solid evidence for the fact that horses had 5 toes in the past.
Metamorphic are formed through change underground sedimentary are formed through sediment
Answer: When using fossils approximate age by comparing it to similar rocks and fossils of known ages, is called relative dating.
Using that method we can determine the age of rock layers. That’s our way of dating them.
Hope this helps! ^^
Answer: by using artificial light (grow light) in place of sunlight
Explanation: Plants generally needs sunlight to grow and survive through a process known as photosynthesis, this is when Plants and other organism uses sunlight to convert water, carbon dioxide and minerals into energy rich compound (starch) while oxygen is been released into the environment.
However in the absence of sunlight, artificial light know as grow light can be used, these lights are design in such a way that it emits lights of wavelengths that are appropriate for photosynthesis. The grow light replaces the sun as a source of photons in the process of photosynthesis.
