Which of the following correctly describes seafloor spreading?A. New oceanic crust is formed at midocean ridges, pushed away from the ridge, and destroyed at deep-sea trenches.

B. New oceanic crust is formed at seamounts and spreads outward in all directions.

C. New oceanic crust is formed at deep-sea trenches, pushed away from the trench, and destroyed at midocean ridges.

D. New oceanic crust is formed in the middle of tectonic plates and then spreads outward in bands.

Answers

Answer 1
Answer: Option D correctly describes seafloor spreading. Seafloor spreading is a process which typically occur at middle ocean ridges where new oceanic crusts are formed as a result of volcanic activity. These oceanic crusts then gradually move away from the ridge.
Answer 2
Answer:

The answer is B. This occurs at mid-ocean ridges, where two tectonic plates are moving away from each other. As they move in opposite directions, the magma from the mantle below rises to fill the void/space left above. As the magma rises, it cools and forms a new crust. This volcanic activity continues as long as the tectonic plates are moving away from each other and new crust is formed spreading outwards from the ridge, with time.

Which means of particle transport requires input of energy from the cell?A) Diffusion
B) Osmosis
C) Facilitated diffusion
D) Active transport

Answers

D) Active transport. In this process, dissolved molecules move across plasma membrane from a lower to higher concentration. Because they move against the concentration gradient, an energy from the cell is required.

For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with the genotype RR and a second parent with the genotype rr will have red flowers?

Answers

Answer:

0%

Explanation:

According to the question, the inheritance pattern of flower colour in four o'clock plants follow incomplete dominance i.e. one allele is not completely dominant over the other, and instead they form a heterozygous plant with a third intermediate phenotype (flower colour).

In this case, a four o'clock plant with genotype RR will have red flowers while a plant with genotype rr will have white flowers, Hence, they cross to form an all Rr genotype offsprings with pink flowers (since the red allele is incompletely dominant). Therefore, the percentage chance of having a red flower offspring from this cross is 0%, as it cannot occur.

Why are leaves green?

Answers

Because of the natural process of photosynthesis that always begins by absorbing light from the sun through proteins. And these reaction centres contain green chlorophyll pigments.
leaves appear green because the photosynthetic pigment chlorophyll is present in the leaves .. when sun light or any other light falls on leaves ,this chlorophyll absorbs all the other colours of light and only reflect green ..so our eye can only detect this green colour and it seems that leaves or chlorophyll is green but actually the matter is with absorption spectrum..
amazing fact :
if you fall red light on grass at night ,they will appear dark because they wont have any green light to reflect and they will absorb red light ..so our eye cant detect any colour :)
