Growth of bacteria in food products causes a need to "time-date" some products (like milk) so that shoppers will buy the product
Yuri [45]

Answer: 19,960,039.97 days

Explanation: f(t) = 200e0.002t

where, f(t) is number of bacteria in millions and t is time in days.

so, if the product cannot be eaten after the bacteria count reaches 4000, it will take:

4,000,000,000 = 200e0.002t

4,000,000,000 = 200.4004003t

therefore, t= 4,000,000,000/200.4004003 =19,960,039.97 days

that is, to say that it will take 19,960,039.97 days  before the product will not be eaten again.

The graph shows the results of an investigation into the effect of distance from a light source on the rate of photosynthesis. ​
jeka94

Answer:

<em>A:</em>

  1. increases
  2. light
  3. low

Explanation:

Photosynthesis is a chemical process in plants and other primary producers that is integral to energy production. Carbohydrates containing energy is made from light, water and carbon dioxide in the form of glucose molecules.

As a result, the waste product oxygen is released. Photosynthesis is a rate-limited reaction, depending on many factors, including the concentration of carbon dioxide, atmospheric temperature and intensity of light. Because the energy needed is derived from photons, i.e. light particles, lower light intensities lower the rate of photosynthesis significantly.

Natural selection story
svetlana [45]

Natural Selection Theory: The Natural Selection Theory is given by Charles Darwin. There are 3 principles of Natural Selection Theory

Variation, Heredity, Selection.

Explanation:

Natural Selection is the cause of evolution. The adaptation to the environment is the key to survival according to Charles Darwin.

The story behind Natural Selection is his visit to Galapagos Islands in 1835. Here he noticed the finches of different varieties in their beaks and food sources adapted to different environments i.e from different islands. This pushed him to think about those adaptations and eventually theory of natural selection.
