<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:
temporal reproductive isolation
Explanation:
The correct answer would be temporal reproductive isolation.
<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.
Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.
Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.
<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>
Answer:
what are you trying to ask about?
What happens to the population density and competition if the birth rate decreases?
The birth rate would increase is the population density competition increased.
Hope I helped.
Explanation:
The enzymatic digestion of starch by amylase can be performed in the laboratory by several ways. But below there is an example of it
In order to have the best protein performance we have to set the temperature of the reaction to 37 celsius degrees.
- Prepare a starch solution and spread into tubes
- Prepare an amylase solution and spread into tubes
- Adjust the pH to the optimum range with buffers, that is about 6.7 to 7.
- Adjust the temperature of the tubes reaction to 37 celsius degrees.
The wrong temperature and the pH can unfold the enzymes and make the binding site inefficient.
- Pipette the starch solution in the tubes with enzymes.
By the final step the glucose will be produced by the enzymatic digestion of amylase.
It's attached the scheme of the hydrolyzation of a starch strain
