Many plants depend on animals primarily insects for pollination and sexual reproduction. If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct.
Both plants and animals undergo cellular respiration producing Carbon Dioxide. Animals produce only Carbon Dioxide while plants produce both Carbon Dioxide and Oxygen. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.
Plants that survived the extinction of animals would be much simpler than presently complex plants.
Perhaps some plants would become predators of other plants to absorb the nitrogen content of other plants because of the lack of animals to engage in the recycling of nitrogen content.

Answer: The correct answer is- B)They are single cells that lack a nucleus and tend to live in extreme conditions.
Archaebacteria are the oldest life forms, which are found on earth. They are unicellular ( made up of one cell) prokaryotes ( lacking nucleus and membrane bound subcellular organelles) belonging to the kindom, Archea. They are found in extremely harsh environmental conditions such as hotsprings, boiling mud surrounding volcanoes.
Example- Methanogens, halophiles.
Thus, option B) is the right answer.
Answer:
Nucleic acids combine to synthesize proteins, from DNA which becomes RNA and when entering the ribosome generates such synthesis.
Explanation:
Protein synthesis is a complex process that begins in the cell nucleus and begins when the protein gene is encoded and expressed by the transcription process. The transcript is the one that transmits the information from the DNA to the RNA (the two nucleic acids).
There is also an tRNA, which carries the amino acids for each messenger RNA where they bind to the proper position, within the protein synthesis
Answer:
Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.
