An intragenic inversion refers to an inversion event that occurs within a single gene on a chromosome.
What is an intragenic inversion?An intragenic inversion refers to an inversion event that occurs within a single gene on a chromosome. As a result of this inversion, several possible outcomes can arise.
Firstly, the order of genes along the chromosome may be altered, disrupting the normal sequence. Secondly, the inversion can cause rearrangement of the gene's DNA sequences, leading to some segments being adjacent to DNA sequences they are not normally connected to.
These changes can impact gene expression and function. However, it is important to note that despite the inversion, the individual bases (A, C, G, and T) within the gene generally remain in the same order as normal. Therefore, the correct options are A, C, and D.

Corticotropin-releasing hormone (CRH)-immunoreactive (IR) axon varicosities target a subset of growth hormone-releasing hormone (GHRH)-IR neurons in the human hypothalamus
It is well accepted that one of the key causes stifling growth is stress.
Previous research has shown that the catecholaminergic and neuropeptide Y (NPY) systems, which are involved in the activation of stress-related neural circuits, regulate growth hormone (GH) release through altering GHRH production.
Catecholaminergic and NPY-immunoreactive (IR) axon varicosities do, in fact, abut the surface of GHRH neurons, creating connections. These juxtapositions appear to be actual synapses and might be the morphological foundation of stress's influence on development.
Aside from catecholamines and NPY, there is a large body of evidence suggesting corticotropin-releasing hormone (CRH), a significant stress hormone, regulates GH secretion.
The architecture of these CRH-GHRH juxtapositions shows that, among other neurotransmitters/neuromodulators, CRH regulates development via direct synaptic processes via influencing hypothalamic GHRH production.

Neural impulses are propogated down the axon by the movement of ions along the cell membrane. Specifically, ___________________ moves in and ________________ moves out of the cell.
The nerve impulse through the neuron is also called an action potential. The sodium ions move into the cell and the potassium ions leave the cell at action potential.
Conduction of nerve impulses:
The transmission of signals from one end of the neuron to another neuron is called nerve impulse conduction. The positive charges are inside the cell and the negative on the outside. There are three phases of an electric impulse: depolarization, overshoot, and repolarisation. The resting potential of the membrane is -70mV. During the depolarization phase, the membrane is depolarized and the sodium ions move into the cell and the potassium ions move outside the cell. The impulse is transmitted from the axon of the neuron with the release of neurotransmitters from the vesicles. These vesicles fuse with the plasma membrane and release the neurotransmitters into the synaptic cleft which then bind to the receptors on the dendrites of another neuron leading to the conduction of nerve impulses.

What are the phases of mitosis?
For revision notes
Answer:
Interphase: The first phase in mitosis can be split up into G (growth) and S (synthesis) phases. In the first G phase, the cell increases in size. DNA is synthesized here (to synthesize is to produce a substance by a chemical reaction). Once this happens, the cell undergoes the G2 phase where there is more cell growth and proteins are produced.
Prophase.
1) Preprophase:
In plant cells only, the cell remains where it is and the nucleus moves around the cell before the start of mitosis through the formation of a phragmosome. In this formation, pre-prophase is the formation of microtubules ring and pre-prophase band under the plasma membrane.
2) Prophase:
A lot of things happen here. The DNA, RNA and proteins combined together - chromatin - merge into chromosomes which are held together by a centromere. Spindle fibers as well as microtubles are then formed in the cytoplasm and the cells organelles eventually migrate to opposite sides of the cell. As prophase continues, the cell nucleus membrane breaks up and the chromosomes move towards the center of the cell.
3. Prometaphase:
This is the end of prophase and an early stage of metaphase. The nuclear membrane breaks up. In addition, the microtubules occupy the nuclear space. Each chromosome forms two kinetochores.
Metaphase
During metaphase the chromosomes line up at the center of the cell along a metaphase plate, exactly in the middle of the cell where it is equidistant from each spindle pole. The chromosomes line up at the metaphase plate randomly until they eventually attach to each other.
Anaphase
The attached chromosomes break apart and move to the opposite ends of the cell. Once there, the “daughter” chromosomes split apart forming single chromatids again.
Telophase
In telophase, the chromosomes then become sectioned off into new nuclei and daughter cells. These nuclei develop nuclear envelopes and mitosis is basically complete with two new daughter cells. The daughter cells are formed with genetic information passed on from the parent cell.
Cytokinesis
The final step, cytokinesis actually takes place near the end of telophase where the two daughter cells now formed split apart into individual cells.
This is a separate process from telophase that begins at the same time as the telophase.
Hope this makes sense. Feel free to ask further for any info.

Synaptic potentials that do not depolarize membrane potential enough to reach threshold are known as hyperpolarization.
Electrical signals that travel from one region of the nervous system to another define it. The signal must move along an axon, regardless of how close together or how far apart those locations are. The carefully regulated ion distribution across the membrane forms the foundation of the electrical signal. In a resting state, the membrane has stable Na+ and K+ concentrations on each side.
A stimulus will cause the membrane to depolarize, and voltage-gated channels will cause the membrane to depolarize even more before repolarizing. Action potentials finish with a slight overshoot of hyperpolarization.
