Answer:
Object is moving away from observer.
Explanation:
If a force is applied to an object it starts moving. The object will move towards the observer, this is known as Doppler effect. It is when an observer or the thing under observation moves. There is change in its position due to a force exerted on it. The motion of the object also depends on the direction of force.
What are the functions of the cells resulting from a double fertilization event? Both cells go on to form embryos. One cell goes on to form an embryo; the other cell goes on to form a protective seed coat. One cell goes on to form an embryo; the other cell goes on to form a fleshy fruit that has a protective function.
Answer:
The mutation will occur in all the cells of the fetus since they all formed by mitosis from the zygote.
Explanation:
<em>If there is a mutation in a zygote, the mutation will occur in all the cells of the fetus since they all formed by mitosis from the zygote.</em>
A zygote consist of a diploid cell formed from the fusion of male and female haploid cells during fertilization.
A zygote develops into a fetus through continuous mitotic division and differentiation.
Hence, if a mutation occur in a zygote, all the cells of the fetus formed from such zygote will have the mutation because the cells are formed from the mitotic division of the zygote.
Answer:
Complex organisms evolved from more simple organisms
Explanation:
<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>
<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>
The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.
