A depletion of fish stocks. Carbon dioxide makes ocean water more acidic which is dangerous to fish.
Wilts, wood rot, sooty molds, rusts, and smuts. These are all types of plant diseases caused by Fungi. For example, dry rot is a wood decay caused by certain species of fungi that digest parts of the wood which give the wood stiffness and strength. All of them are plant diseases caused by fungi.
Segments of dna capable of moving from one area in the dna to another are called: transposable elements or "transposons."
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
