Prokaryotes are the Earth`s firs living things. This are the simplest life forms exhibiting ( showing ) cellular structures.
They exist in 2 major forms:
- Eubacteria ( most of the common bacteria that are found everywhere ),
- Archaebacteria ( ancient bacteria that live in very extreme conditions ).
Answer: Prokaryotes.
Answer:
Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.
Explanation:

Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.
Answer:Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. Over millions of years of intense heat and pressure, these organic remains (fossils) transformed into carbon-rich substances we rely on as raw materials for fuel and a wide variety of products.
