Answer:
enzymes are proteins. they are playing important role in normal functioning and survival of an organism. enzymes are substrate specific. each enzyme is specific for its substrate and in absence of this enzyme the metabolism of that substrate stops.
Explanation:
according to above discription without enzymes survival of an organism is not possible.
If pea plant cells contain 14 chromosomes, a pea plant's gamete cell contains 7 chromosomes.
<h3>Describe chromosomes.</h3>
Chromosomes are a pair of thread-like structures that are found in cells.
Re genes and a person's personality are found on the chromosomes.
Meiosis causes the daughter cells to contain half of each chromosome.
<h3>What does a chromosome do primarily?</h3>
Chromosomes' primary role is to transport DNA, which is the building block of all genetic material. DNA contains the genetic instructions for a number of cellular processes. These activities are necessary for the organisms' development, maintenance, and procreation. Chromosomes are shielded by proteins like histones.

The correct answer is option A , sensory system.
A human body primarily consists of the following organ systems :
Circulatory, Respiratory, Digestive, Excretory, Nervous and Endocrine systems, Immune, Integumentary, Skeletal, Muscle and Reproductive systems.
There is no as such sensory system. However the neurology based system is called Nervous system which includes organs and their processing in the sensing of stimulation.
This type of organism is called an autotroph.They are organisms capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy
Answer:
Analogous structures
Explanation:
These structures are similar but not derived from the common ancestor like homologous structures. Analogous structures are formed as a result of convergent evolution-type of evolution in which organisms develop on similar way but independently. An example of analogous structures are wings. Birds, insects and bats all have wings, with the same purpose (flight) but they evolved in their own way.
