Answer:
The mitochondria, also called the powerhouse of a cell, is present in large numbers in almost every cell in the body.
Explanation:
Answer:
The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.
Explanation:
In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.
These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.
A solid minute object that is said to come together for the formation of the planet and are believed to produce cosmic dust are called planetesimal.
The options that best describes the planetesimals are:
- Option A. They are the origins of planets.
- Option B. They formed from gas and dust.
- Option D. They are believed to have developed in debris disks.
The descriptions can be explained as:
- It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.
- By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.
- This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.
Therefore, options A, B and D are correct.

I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.
The shape of a plant cell is a square, while the shape of an animal cell is circular. Hope this helps! :)
