<span>1) stimulate rapid shoot growth while slowing down root growth and increasing the need for more frequent mowing; 2) deplete the plant's carbohydrate reserves more rapidly, which in turn can result in less stress tolerance and slower recovery from any injury to the plant; 3) result in thinner, more succulent leaf tissue, which increases moisture loss and therefore creates a greater need for water; 4) can predispose the plant to greater insect and disease problems</span>
Answer:
The answer is "They contain half a set of chromosomes"
Explanation:
Diploid cells have two complete sets of chromosomes.
P ( fail U infection ) = P ( fail ) + P ( infection ) - P ( fail AND infection )
==>
0.03 + 0.16 - 0.01 = -.18
==>
P ( success AND infection-free )
==>
1 - 0.18 = 0.82
==>
Therefore, 82 percent of these operations succeed and are free from infection.
Answer:
The answer is C - Naturalistic
Explanation:
Naturalistic theory is a philosophical and artistic view based on the belief that nothing exists beyond the natural world and all explanations come from the laws of nature. It proclaims that everything in the universe are natural and all understanding of the universe falls within scientific investigation.
Answer: Na+ channels are closed
Explanation:
The refractory period describes a period between the initiation of an action potential (where Na+ channels are active/open), and immediately after the action potential’s peak. In the absolute refractory period, action potentials cannot be generated, as Na+ channels are in an inactive or closed state, they usually take around one or two minutes.
After the absolute refractory period the relative refractory period (RRP) occurs. During the RRP, it is hard to send another action potential. Na+ channels are once again open, but the cell remains hyperpolarized- its membrane potential, remains negative. Recovery from inactivation is voltage and time-dependent; Action potentials would require an influx of more positively charged ions. These must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
