B. they are defined by their biotic factors and abiotic factors.
<h2>
Answer:</h2>
<u>A) Break down of lactose</u> and production of glucose.
<h2>
Explanation:</h2>
Β-galactosidase is a glycoside hydrolases and breaks the lactose polysaccharide into two different monosaccharide called galactose and glucose. It is significant for life forms as it is a key supplier in the generation of vitality and a wellspring of carbons through the separate of lactose to galactose and glucose.
It is additionally significant for the lactose bigoted network as it is liable for making sans lactose milk and other dairy items.
The function of beta-galactosidase is shown in the image below.
An abiotic factor would be a Rocky Desert Soil.
Answer: Carbohydrates in the form of glucose and oxygen as byproduct.
Explanation:
Photosynthesis is a process which occurs in green plants and in other autotrophs. In this process the autotrophs can prepare their own food by using reactants like water and carbon dioxide to produce glucose which is a carbohydrate which a major source of energy for plants and oxygen gas is released as a byproduct of this chemical reaction. On the contrary to this the cellular respiration can be defined as the process in which the biochemical oxidation of food occurs and energy is released in the form of ATP and carbon dioxide and water are produced.
Thus in photosynthesis the carbon dioxide and water are the reactants whereas in cellular respiration they are the products.
