<span>The ash trees are being cut when the show signs of
infestation of the ash borer. Ash borer in particular the Emerald Ash Borer
(EAB) is a tiny bug but can really do a great damage to the tree. When the tree
is infested with the ash borer, they lay their eggs in the bark of tree, when
the eggs hatch the lavas would start eating on the inner tissues of the tree
blocking the flow of nutrients and water in the tree that causes the tree’s to
death. If the tree is infested they cut
it down, burn and bury the wood to stop the spread of infestation. Ash trees
are valued for its strength and elasticity that is often used to make baseball
bats, bows, tool handles and other products that needs durable wood.</span>

Answer:
This constancy of the chemicals involved denotes that no particular reaction is taking place on the cells involved. For instance, during photosynthesis it would require CO2, H2O and photons to initiate the process. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
Answer:
42,5 mL
Explanation:
We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.
<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>
The first step is to have the same measurment unit so we need to convert 345 µg to mg.
we know that 1 µg equals 0,001 g, hence:
now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula
Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL
So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)
I don't think so much for all your friends and family
