Answer: Option D
Explanation:
The embryonic induction can be defined as the critical part in formation of the other tissues and organs because one cells affects the development of the other cells.
In vertebrates the notochord arises from the dorsal organiser, in amphibian the organizer is a region of vertebrate gastrulae which is when transplanted into the ventral region of the host embryo stimulates the formation of second embryonic axis and neural tube in embryo.
This generation of second notochord in the an example of influence of one group of cell on other.
I think that a basic experiment involves a minimum of two participants group(s). Simple or basic experiment are ones that researchers use to determine if changes in one variable might lead to changes in another variable. In these experiments looking at the effectiveness of a new medication, for example, study participants may be random.
<span>In human beings the "master switch" that determines whether an individual will become a male is the SRY gene, which is found on the Y chromosome. The sex-determining region Y protein produced from this gene acts as a transcription factor, meaning it attaches to specific regions of DNA and helps control the activity of particular genes.</span>
Answer:
The correct answer will be option A-more complex.
Explanation:
The brain is divided into three parts: cerebrum, cerebellum and Brainstem.
The medulla oblongata is a part of the brainstem which is involved in the response of the autonomic nervous system (ANS) like body temperature, breathing, digestion, heart rate, wake and sleep cycles, vomiting, sneezing, coughing and swallowing.
The cerebrum is the largest part of the brain which includes basal ganglia, hippocampus and olfactory bulb. This is involved in performing the higher functions of the central nervous system (CNS) like vision and hearing, speech, emotions, reasoning, learning and fine control of movement.
As we move from the medulla oblongata to cerebrum the response to stimuli changes from simple to complex as medulla oblongata is involved in simple processes of ANS whereas cerebrum is involved in the higher process of CNS like learning, speech and many more.
Thus, option A-more complex is the correct answer.
