Emperor penguins leave and stay for winter months.
Answer:
Endosymbiont theory was proposed by Lynn Margulis in 1967 which suggested the origin of Chloroplast and mitochondria in eukaryotic cells.
The theory suggested that chloroplast and mitochondria organelle originated by engulfing the cyanobacteria and proteobacteria by other prokaryotic bacteria.
This shows that Prokaryotes exhibit the following characters:
1. These were the first organisms on Earth
2. Lack membrane-bounded
3. Aerobic bacteria are these types of cells
Eukaryotes exhibit:
1. Have mitochondria
2. Includes organisms that carry out aerobic respiration
3. Can be a multicellular organism
4. Includes organisms that are photosynthetic
5. Might have chloroplasts
Answer: C
Explanation: The atomic mass is 22.990 so it would be C
The terrestrial planets are Mercury, Venus, Earth, and Mars.
Here's the explanation in regards to the Goldilocks Theory.
The Goldilocks Theory is often used by astrologists to describe the conditions of Earth's positioning in the solar system. The Goldilocks Zone was described by Stephen Hawking as "like Goldilocks, the development of intelligent life requires that planetary temperatures be ‘just right’” The Goldilocks theory argues that a planet must be neither too far away from nor too close to a star and galactic center to support life, while either extreme would result in a planet incapable of supporting life. Terrestrial planets such as Mercury, Venus, Earth, and Mars are more likely to lie in the Goldilocks zone due to their close proximity to their home star along with other crucial factors that allow for life to exist.
