to see if they can find any other information to see what it worth how valuable it is or wht it is
Answer:
Mushrooms with gills, typically available in supermarkets, have meiotically produced spores located in or on BASIDIA and belong to the phylum BASIDIOMYCOTA.
Explanation:
Mushrooms are fruiting bodies of certain fungi that belongs yo the phylum BASIDIOMYCOTA. They are incapable of producing their own foods( because of lack of chlorophyl) therefore are saprophytic in nature. It derives its nutrients for growth from metabolizing non living organic matter.The structure that you normally see above the ground is the part of the mushroom that is producing and dispersing spores which is located at the BASIDIA.
Mushroom are used for different purposes:
- the edible species are useful in cooking since it provides vitamin D to the diet.
- it's extracts can be used for medical purposes.
There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living organisms.
There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.
Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species. Confounding factors rack up for species that are very distantly related, making the earlier dates more uncertain.
These difficulties mean that the dates in the timeline should be taken as approximate. As a general rule, they become more uncertain the further back along the geological timescale we look. Dates that are very uncertain are marked with a question mark.
Answer:
A healthy artery is wider and has no blockages. The lumen (which is the hole in the centre of the artery), is open and clear. This means there is more blood flow. An artery of a person suffering from coronary heart disease is often blocked, usually by a fatty deposit. This means the blood does not flow as well. (See diagram, in which I would draw two arteries, one with a blockage of fatty deposit, one clear and healthy).
