<u>Full question:</u>
Which of the following is/are characteristic of the earth but not the moon? A. Molten core B. Plate tectonics C. Asteroid impacts D. Volcanoes
<u>Answer:</u>
Plate tectonics is characteristic of the earth but not the moon
<u>Explanation:</u>
Tectonic plate movements in Earth are forced by convection in the mantle-the hard mantle transits at rates of a some centimeters a year. The Moon’s mantle, too cool to travel easily, has no convection and no moving tectonic plate motions. More uncommon movements inside the Moon indicate fewer quakes. The few moonquakes that do happen are made fundamentally by gravitational tugs by Earth and Sun ).
The quantity and intensity (magnitude) of moonquakes is much less than the quantity and consequence of earthquakes. The feasible reason of this discrepancy is the Moon's smaller size and cooler interior. Earth is hot and active, manifested most dramatically in plate tectonics. The secret of plate tectonics is that the Earth has gaps between the continents, and so they can move around like a sliding block puzzle.
Well i know you need carbon nitrogen and oxygen but there might be more
The most important factor that limits the size of a cell is the ability of the cell to transport materials efficiently into and out of the cell. In this case the size of a cell should have a particular form in order to export and import material.
Answer No 1:
The trait which is being studied in the cross is the height of the pea plant.
Answer No 2:
The two alleles for this trait are tall height allele which we can write as T and the allele for short height which we can write as t.
Answer No 3:
The allele for tall height is the dominant allele. We can say this because when a cross between a dominant homozyous and a recessive plant were made the offsprings resulted in the tall plants which is the F1 generation in the figure. As a dominant trait masks the recessive trait, hence we can say that the tall height allele is dominant over the short height allele.
Answer No 4:
The allele for short height t is recessive because as we can see the short height trait is being masked by the tall height trait in the F1 progeny. In F2 progeny, there are more number of tall height plants produced which further prove that short height is the recessive trait.
Answer No 5:
The F1 offsprings will have a dominant tall height allele, T, and a recessive short height allele, t. The dominant allele was inherited from the tall parent and the short height allele, t, was inherited from the recessive parent.
We can say that because the F2 progeny shows some plants to have short heights which is only possible if the F1 generation has heterozygous dominant (Tt) alleles.
Two examples include Cyanobacteria streptococci. Prokaryotes don’t really create systems into higher orders of living things so they create chains like the two I mentioned
