<u>Answer:</u> C. A plant absorbing carbon dioxide during photosynthesis
<em>A plant absorbing carbon dioxide during photosynthesis can be considered as assimilation in the carbon cycle.
</em>
<u>Explanation:</u>
<em>The process of carbon fixation is called assimilation in carbon cycle. In the atmosphere carbon occurs in the form of carbon dioxide. </em>
By the process of carbon fixation this carbon dioxide is converted into carbon compounds and these act as source of energy in an ecosystem.
Photosynthesis is an example of carbon fixation process. Other processes like chemo-synthesis also fix carbon. <em>Majority of carbon fixation takes place in marine environments. </em>
The right answer is a. they contain many small, repeating subunits bonded together.
In chemistry and biology, a polymer is a molecule made up of a chain of similar molecules, called monomers; a polymer is a macromolecule resulting from the assembly of many identical units (monomers), a chemical compound with repetitive structural units.
DNA, glycogen and proteins are polymers
Answer:
<h2>2. Peter's maternal grandfather has PKU.</h2>
Explanation:
- Such type of the genetic disorder in which two copies of a gene must be mutated at a time is called autosomal recessive disorder such as sickle cell anemia, phenylketonuria, and some other diseases.
- When a sing copy of a gene is mutated in a person then this disorder is not appeared and the person is called a carrier.
- So when a child is born by two carrier parents then there is a chance that a child will be affected if both the parents donate mutated genes.
- In the case of Peter, since peter does not show this defect this means his maternal grandfather was affected by this disorder.
