Pollen , coal and stems are evidences that plants existed in Antarctica.
Explanation:
- Pollens being highly resistant to temperature changes due to the presence of sporopollenin must have remained preserved in ice covered continent of Antarctica.
- Pollens are reproductive units of Plant that suggest existence of plants in the Ice covered land.
- Coal is formed as the fossilization of plants under anaeorobic conditions and high pressure. thus, this also suggest the existence of plants.
- Stems are plant parts thus clearly is an evidence that plants existed there.
1. hydrogen atoms crash together
Hydrogen atoms (or protons) fuse within the Sun core and fall apart.
2. helium atoms are formed
Helium atom is a product of the proton-proton fusion and this process occurs through a series of steps.
3. an enormous amount of energy is released
The transformation that occurs after the fusion results in a release of huge amount of energy that keeps the sun hot. Energy is radiated out from the core of the Sun
4. energy travels to Earth in the form of light energy and heat
This energy is called The Solar energy to the Earth because it hits the surface of the Earth itself.
5. plants will use energy from the sun to make their own food
Plants are phototrophic organisms that transform the light energy into usable energy for their metabolism.
Answer:
The cell would fail to function. It would likely fail to properly replicate DNA properly or transcribe genes.
Explanation:
The nucleus holds the genetic information, the DNA. If the nucleus does not grow properly, the DNA might not fit or be properly organized inside. This would mean DNA replication could not proceed as normal, and the DNA might not even be able to fit inside the nucleus!
The cell would also struggle to properly transcribe the DNA if the nucleus is not fully formed. DNA acts as a template for mRNA transcription, which directs protein synthesis. The cell will very quickly die if there are inaccuracies in protein synthesis due to mRNA not being adequately synthesized.
