Answer:
Cephalocaudal.
Explanation:
Cephalocaudal refers to the head to the toe of the body. The cephalocaudal principle denotes the motor and the physical development of the individual infants to the early childhood.
This principle explains the phenomena of the post natal development and includes the development of the weight, size, and differentiation of the body. The development always occur from the top to the bottom fashion. The first control of the head will occur and later the toe.
Thus, the answer is cephalocaudal.
Answer:
I believe it is D
Explanation:
Complementary base pairs are held together by hydrogen bonds. Adenine and Thymine go together. Cytosine and Guanine go together.
The influx of positive charges makes the membrane potential more positive and is known as depolarization.
<h3>
What makes the membrane more positive charge ?</h3>
The membrane potential normally becomes more positive in response to neurotransmitters that open Na+ channels, more negatively in response to those that open K+ channels, and vice versa in response to neurotransmitters that inhibit these channels.
<h3>What does polarization mean?</h3>
The orientation dispersion of the electromagnetic waves that make up light beams is referred to as polarization. Unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized are some of the different polarization states that light can take on (rotating field about the line of sight).
<h3>How membrane is affected by polarization and depolarization?</h3>
At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).

Population decline causes an extreme genetic drift called a bottleneck effect. The correct option is C.
<h3>What is bottleneck effect?</h3>
The bottleneck effect describes how a population's size is reduced and then increased, affecting the distribution of genetic variation among its members.
It happened when the population reduced severely. Events like natural disaster or decline of the population.
Thus, the correct option is C) bottleneck effect.
