Answer:
By definition, baryonic matter should only include matter composed of baryons. In other words, it should include protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude things such as electrons and neutrinos which are actually leptons.
since on astronomical scales, protons and neutrons are always accompanied by electrons (in appropriate numbers for astronomical objects to possess all but zero net charge). Astronomers therefore use the term ‘baryonic’ to refer to all objects made of normal atomic matter, essentially ignoring the presence of electrons which, after all, represent only ~0.0005 of the mass. Neutrinos, on the other hand, are (correctly) considered non-baryonic by astronomers.
I think the answer is B
Beacuse It follows the successful completion of S phase, during which the cell's DNA is replicated. Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
Answer:
The correct answer is a. the photosynthetic part of a lichen.
Explanation:
Lichen is a symbiotic association in which the algae and fungi are associated with each other. Fungus can not make there own food so they are not photosynthetic like algae or plants and in lichens algae are the photosynthetic part while fungus plays the role of absorbing nutrients for the algal partner.
Lichens are found all over the world and they absorb industrial pollution very quickly so are also referred to as pollution indicators of the environment as they do not grow in a polluted area.
Therefore the photosynthetic part of lichen is algae, not fungus so the correct answer is a.
