Answer:
plant material
Explanation:
After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal.

Which reaction is endothermic?
Answer:
Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

Among evolutionary mechanisms, there can be mentioned non-random matings (1 and 8) , mutations (3 and 6), genetic drift (2, 4 and 5), and genetic flow (7).
What are evolutionary mechanisms?These are different mechanisms that change allelic frequencies and genotypic frequencies conserning the expected ones if populations were under Hardy-Weinber equilibrium.
When these mechanisms are going on, populations evolve.
Among them, we can mention,
Non-random matings Mutation Genetic drift Genetic flowIn the attached files you will find a better explanation about evolutionary mechanisms

How is information contained within a molecule of DNA?
Answer:
DNA stores biological information in sequences of four bases of nucleic acid.
Explanation:
— adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Answer:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each moleculeof DNA is a double helixformed from two complementarystrands of nucleotides held together by hydrogen bonds between G-C and A-T basepairs.

Removing a flower’s stigma would initially affect
Answer:
Pollination.
Explanation:
Removing a flower’s stigma would initially affect pollination.
Removing a flower’s stigma would initially affect pollination.
The stigma is found in the pollen-bearing part of the flower, which is called the “gynoecium”. The stigma’s primary purpose is to pull pollen grains out of the air using its sticky tip in order to reproduce.
If a flower does not have an anther or stigma, then the flower may be cross-pollinated. Cross-pollination occurs when pollen from one flower fertilizes the pollen of another flower. In other words, pollen from one plant fertilizes pollen from another plant.
When the stigma is taken off before pollination occurs, then the pollen grains do not collect in the receptive area of the flower.

How long does humans know that long gone animals have been on earth?Explain why or why not?
Answer:
Fossils
Explanation:
By using fossils we can not only know that extinct animals once roamed the planet, but also get an estimate of when they did so. We can use fossils to pin down their location (which we can use to see what might have killed them, resource loss, climate change, human interaction, etc.), to see when they appeared and went extinct (thanks to rock layers and knowledge of geology), and even what may have been in their diets (based on location or.. well, other pieces of evidence, if you know what I mean.) Fossils also give you their size and shape which can help paleontologists determine the type of animal, ex. birdlike, reptile, mammal, etc.

Which of the following best describes how crossing over occurs during meiosis?
During prophase I, homologous chromosomes are lined up and pulled apart to opposite poles.
During prophase II, sister chromatids trade places with each other before metaphase begins.
During prophase I, segments of chromatids are exchanged between homologous chromosomes.
During prophase II, spindle fibers begin to form, attaching chromosomes together.
During prophase I, segments of chromatids are exchanged between homologous chromosomes.
What is crossing over?Crossing over is the exchange of chromatid segments between homologous chromosome pairs during the early stages of meiotic division.
Crossing over occurs after the pairing of chromosomes to form tetrads at prophase I of meiosis I.
