When charged particles from the sun strike atoms in Earth's atmosphere, they causeelectrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights
Answer:
The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.
Explanation:
This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.
According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.
This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
Answer: synthesizing of complex molecules
Explanation:
During the synthesizing of complex substances (catabolism) energy is given off to the body to generate heat within the body
The correct answer for this question is (D) It can proceed in the dark.
Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>
The Calvin cycle proceeds in three stages:
1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate
2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH
3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.
Answer:
The average speed of the fish is:
Explanation:
You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:
- 720 m * 10 = 7200 meters.
Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:
- 7200 m / 120 min = <u>60 m/min
</u>
Remember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.
