Fungi of the phylum Basidiomycota form mycorrhizal
Reika [66]

Answer:

The orchids derive nutrients from the association at very young stages of its life cycle while the fungi obtain water and organic matter

Explanation:

As stated in this question, fungi species belonging to the phylum Basidiomycota form mycorrhizal associations with a flowering plant called orchids. This relationship is a mutualistic one because both participants benefit from the relationship.

In this association, the young orchid plant relies on the mycorrhizal fungi's metabolism to get nutrients needed for its development in form of carbohydrates while the fungi in return gets water (from the roots of the plant) and organic matter.

lidiya [134]

Answer:

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.  

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

A segment of DNA is 400 base pairs long and contains 2 restriction sites for the restriction enzyme HindIII. This DNA is cut wit
r-ruslan [8.4K]

Answer:

I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.

Explanation:

The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.

     As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.

     The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.

Sodium has the atomic number 11. How many electrons are in a sodium ion, which has the symbol Na=?
AlladinOne [14]
Atomic number is the number of protons of an atom. And, given that the atoms are electrically neutral and the charge of one proton is equal to the charge of one electron, the number of electrons is equal to the number of protons. So the neutral atom of sodium has 11 protons and 11 electrons. But, the sodium ion (Na+) has one positive charge, that means that it has lost one negative charge or one electron. Then, the sodium ion (Na+) has 11 - 1 = 10 electrons. <span>Then, the answer is that there are 10 electrons in a sodium ion. 

hope this helps :3</span>
