Remember that a biotic factor is a living component in an ecosystem that affects the population of another organism. So that means that the answer is B.
Explanation:
Create the column headings "Reactants" and "Products". The two row headings should be "Photosynthesis" and "Cellular respiration".
Before filling in the table, make sure you know what the products and reactants from photosynthesis and cellular respiration are.
Remember reactants are the 'before' on the left, and products are the 'after' on the right.
<u>Photosynthesis</u>:

<u>Cellular Respiration</u>:

See attachment for how the table could look.
Answer:
Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.
Explanation:
The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.
<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>
To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.

Explanation:
Hydroponics way of growing, is way of farming, in which plants are grown in nutrient rich water. So, in Hydroponic growing of sprouts, sprouts get their nutrients from the nutrients supply like liquid fertilizers which are mixed with the water. It is one of the advantage of hydroponic means of growing because, unlike in soil system, the plants root does not have to work hard to get nutrient from underground. The easy availability of nutrients and other condition like water, pH level etc makes plants grow faster are fuller.
Also, advancement of technology have made it possible to prepare built-in hybrid hydroponic system which have multiple ways of delivering nutrient to specific plants.
