Tropism is a descriptive reaction of a certain stimuli on how an organism responds to the confronted stimuli which can be called positive tropism or negative tropism.
<span>In positive tropism as the proposed answer </span>toward <span> involves the organism leaning forward or direct to the acting stimuli whereas the negative tropism is exactly the opposite. </span>
The process is likely to be triggered by the formation of the layers. Zygote is the structure that forms when a sperm fertilizes an egg, the zygote then divides many times by the process of mitosis to form an embryo. That is, it forms two cells, then four, then eight and so on, up to the eight stage the cells are identical and are called embryonic stem cell, which then develop into any specialized cells type by differentiation, that the growing embryo needs, such as the nerve cells, blood cells, among others.
Answer:
<em>The correct option is D) glial cell</em>
Explanation:
The function of the glial cells is to cover the neurons and to provide insulation between them. They also supply the neurons with oxygen and nutrients. The glial cells are also involved in protecting the neurons from pathogens and removing the dead neurons. Hence, glial cells perform functions other than producing actions when a stimuli is detected.
Other options like option B, sensory neurons, helps to convert external stimuli into electrical impulses.
<span>DNA replication involves unzipping the DNA molecule, followed by base pairing, which adds complementary nucleotides, to form two new identical DNA molecules that move to the new cells during cell division.</span>
