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
Answer:
results much like those obtained in western cultures
Explanation:
Explanation:
The Earth's magnetic field protects us by deflecting much of the incoming solar radiation. Without it, our atmosphere would be stripped by solar winds.
Satellites can and do suffer damage from solar storms, and without Earth's magnetic field, every electronic device could be exposed to high-energy particles from cosmic rays and the solar wind. If Earth lost its magnetic field, there would be no magnetosphere and no line of defense, even from weaker solar storms
Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
Answer:
C
Explanation:
It is right trust me. It needs a longer beak to reach food in smaller areas and it has adapted to the enviroment in many years
