<span>Lateral roots that extend out are called called tap roots.
The first root which develops from a radicle and becomes dominant is called a taproot. Roots that develop from other roots are generally termed as lateral roots; >Roots that arise from other plant organs rather than the root, are called adventitious roots.</span>
Answer:
Visible light, ultraviolet light and infrared light
The correct answer is: The recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.
Natural selection (adaptation mechanism), gene flow, and mutation combine to change allele frequencies across generations. Natural selection tends to increase in frequency beneficial alleles, while it tends to decrease in frequency deleterious alleles.
Answer/ explanation :
Reflex response is an involuntary, automatic and rapid response to a stimulus.
It's is controlled by the brain stem.
Reflex actions cannot be controlled. They are coordinated by nerves which moves to and fro in the spinal cord without a direct involvement of the brain.
Examples of a reflex response
Sneezing, coughing, yawning, toughing a hot object, blinking of the eyes.
There are two types of reflex response
Autonomic reflex arc
The somatic reflex arc
The reflex responses happens so quickly because they do not have to be processed by the brain before taking place.
This is why natural selection acts on phenotypes instead of genotypes. A phenotype is an organism's physical traits, while a genotype is an organism's genetic makeup. This may sound counter-intuitive since the genetic makeup does get<span> passed on from generation to generation through reproduction.</span>
