Mitochondria, or the "powerhouse of the cell" produces energy by breaking nutrients and creating a series of biochemical reactions in a process called cellular respiration. The mitochondria essentially makes ATP, a rich energy currency...
Answer is D
<span>The crossed flies are heterozygous so they have one allele of each for the characteristics. So the genotype is Bb for body color and Rr for eye color.
To set up the punnett square, you would determine all possible combinations for the alleles that each parent could provide: BR, Br, bR, and br. Then make the table, and combining the rows and columns:
BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
There are sixteen combinations of the genotypes and they need to be classified: BB or Bb- Brown body; bb- black body; RR or Rr- red eyes; rr- brown eyes
Brown body and red eyes- 9
Brown body and brown eyes- 3
Black body and red eyes- 3
Black body and brown eyes 1</span>
Earth's axis of rotation changes direction twice during this time explains the pattern of daytime & nighttime that occurs every 24 hours on Earth.
<h3>What about earth's axis?</h3>
- Every 365 days, the Earth revolves once around the sun, and every 24 hours, it rotates around its axis.
- Instead of the Earth orbiting the sun, day and night are caused by the planet rotating on its axis.
- One day encompasses both daytime and nighttime and is measured by how long it takes the Earth to complete one rotation around its axis.
- The Earth rotates on its axis more slowly than it does in relation to the Sun.
- Day and darkness are caused by the Earth's rotation, while the seasons are caused by its revolution.
- The tilt of the Earth's axis is what causes the seasons.
- The Northern Hemisphere is inclined toward the sun during the summer, allowing it to receive more direct sunlight.

Answer: The options are not given, here are the options from another website.
A. metamorphis
B. pupae stage
C)simple life cycle
Question 2
A)breathes through lungs
B. forms a pupa
C. lives completely underwater
The correct answers are A A.
Explanation:
Salamander go through process of metamorphosis that reproductive changes. They have a larvae stage that breathe through gills because the larvae are inform of a fish and gave gills for respiration while the adults breaths through lungs. The larvae stage develops 30 days after hatching and can possibly change into an adult like 60 after hatching.
