The correct answer is b.
The child is reaching for a toy which is not visible to him (hidden under a cloth), therefore, the child has a mental representation of the object in his/her mind. This action means that the child acknowledges that the objects continue to exist even when he/she can not hear or see them. This thought process is called object permanence and it is an ability acquired between the 4th and 7th month of a child's development.

many organisms that undergo chemosynthesis use instead of to fuel the processes that convert carbon dioxide into sugars.
OLEGan [10]

Answer:

Many organisms that undergo chemosynthesis use hydrogen sulphide (H2S) instead of sunlight to fuel the processes that convert carbon dioxide into sugars.

Explanation:

Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.

Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulphide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis. Example, bacteria and methanogenic archaea living in deep sea vents
