It is an example of Fixed Action Patterns.
What are fixed action patterns?
A fixed action pattern (FAP) is a predetermined set of behaviors that happen in a predetermined order in response to a sign stimulus, which is an external stimulus. The behavior is "fixed" because it is essentially unchanging and behaves consistently among members of a species.
FAPs are inherent, which means that the animal is born with the capacity to engage in the behavior and does not require learning. FAPs are also typically finished after being triggered. The ability to instinctively identify and attack prey or, as in the case of sticklebacks, the ability to produce more young that can survive to adulthood are just two examples of how these behaviors may be crucial to improving an animal's fitness.

The majority of neurotransmitters migrate across the synaptic gap and latch onto receptor sites of the receiving neuron's:
Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.
What is a synapse?
Neurons are cells that communicate with each other through the transmition of nervous impulses.
Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.
Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.
During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.
This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.
Dendrites are the structures that receive chemical messages from the other cells.
The correct option is D. Dendrites.

Phenytoin blocks the opening of voltage-gated na channels in neurons. therefore, this action has its primary effects on which part of the neuron?
Numerous antiepileptic medications, such phenytoin, have been designed to block voltage-gated sodium channels (VGSC) in neuronal membrane. In addition, multiple toxins and pharmacological modulators work by attaching to various biophysical states of the VGSC to cause their effects. Depending on how modulatory agents act, some VGSC states are stabilized or destabilized, altering the channel's biophysical properties. The first anticonvulsant to successfully treat epileptic disorders without causing undesirable side effects such as brain drowsiness was phenytoin.
Phenytoin has been indicated to block high-frequency neuronal activity potentials from the inner vestibule of the pore, as demonstrated by electrophysiological research and site-directed mutation.
Frequency and voltage both affect phenytoin binding.
There are theories that phenytoin interferes with the late sodium current that sustains depolarizations in epilepsy by blocking non-inactivated channels.

gene that is expressed only in the homozygous state
A gene that is expressed only in the homozygous state is known as recessive.
Alleles of a gene can be either dominant or recessive. Dominant alleles show their effect even when they are present in the heterozygous state. The recessive alleles only show effect when in homozygous state. Only the homozygous individuals, which are the ones having two copies, will experience the effects of recessive alleles.
For example, the allele for blue eyes is recessive and is represented by "b" and the allele for brown eyes is dominant and is represented by "B". If the genotype of the individual is BB or Bb, they will have brown eyes as they B is the dominant allele. If the genotype of the individual is bb, they'll have blue eyes as b is a recessive allele and will only show effect in homozygous condition.

Explanation:
Based on today's reading, CRISPR is most likely to be more successful in embryos and adolescents instead of adults. Why is that?
A) Adolescent muscle cells in adults don’t typically divide and therefore don’t have the necessary DNA repair machinery turned on for adding or correcting genes.
B) Mature muscle cells in adults don’t typically divide and therefore don’t have the necessary DNA repair machinery turned on for adding or correcting genes.
C) Mature muscle cells in adults divide and therefore have the necessary DNA repair machinery turned on for adding or correcting genes.
Option B is Correct. Because mature muscle cells in adults don't frequently divide, they lack the requisite DNA repair mechanisms for introducing or changing genes.

Answer: Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker. By contrast, an individual who is homozygous for a marker has identical versions of that marker.
Organisms can be homozygous or heterozygous for a gene. Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous. People with CF are homozygous recessive. Since Huntington's disease is autosomal dominant, people with the disease can be either homozygous dominant or heterozygous.
