The nervous system is divided in two parts:
The central nervous system (CNS)
The peripheral nervous system (PNS)
1. CNS
The CNS consist of the brain and the spinal cord and its main function is to integrate and command the body. It uses the information obtained from the entire body and uses it to coordinate the organism's activity.
The brain is located inside the skull and the spinal cord is located inside the vertebrae. This helps protect the CNS.
The tissue that conform the CNS is grey matter (consists of neurone cell bodies and their dendrites, glial cells and capillaries) and white matter (host the majority of axions which are the long cords that extend from neurons).
2.PNS
The PNS consists of nerves that branch fromm the spinal cord and cover the entire body. It is formed by 12 pairs of cranial nerves, 31 pairs of spinal nerves and some small neuronal clusters called gaglia.
The PNS is the connection between the CNS and the body.
The PNS has no bone protection
Together the CNS and the PNS form the nervous system and transmit signals between the brain and the rest of the body, controlling the ability to move, breathe, see, think and many more.
The 3 accessory organs of the nervous system are:
The meninges: it is a set of 3 membranes that cover the brain and the spinal cord.
The cerebrospinal fluid: it is a lymph-like fluid that acts as a protective cushion for the CNS.
Ventricles: these are cavities that contain ependymal cells and blood vessels

Estimate daily energy needs for an active 60 kg man to gain weight and a 70 kg sedentary woman to lose weight
Women: BMR = weight in kilos x 2 x 11.
Men: BMR = weight in kilos x 2 x 12.
An active 60 kg woman's daily energy requirements for weight loss are 2,027 divided by 0.85, or 1,723 kcal.
An energetic 60 kg man needs 2,027 x 1.2 = 2,432 kcal per day to gain weight.
How do you calculate energy based on weight and age? The PAL value by the BMR, they were transformed into energy units (i.e. joules and calories). Requirements were divided by the weight employed in the equations to predict BMR in order to express them as energy units per kilogram of body weight. This computation is illustrated by the example given below for a population of females who lead a moderately active lifestyle and have a mean body weight of 70 kg:As a rule of thumb, BMR uses 11 calories for every 0.5 kg of a woman’s body weight and 12 calories per 0.5 kg of a man’s body weight.
Women: BMR = weight in kilos x 2 x 11 (alternatively weight in pounds x 11)
Men: BMR = weight in kilos x 2 x 12 (alternatively weight in pounds x 12)
Example: BMR for a 60 kg woman = 60 x 2 x 11 = 1,320 kcal.
You can either multiply the number above (maintenance calorie needs) by 0.85 or reduce your daily calorie consumption by 15%. A weekly fat reduction of roughly 0.5 kg will result from this. An active 60 kg woman's daily energy requirements for weight loss are 2,027 divided by 0.85, or 1,723 kcal.
The preceding number (maintenance calorie needs) should be multiplied by 1.2 or increased by 20% everyday. Expect a weight increase of 0.25–0.5 kg per month when combined with a resistance training regimen. An energetic 60 kg lady needs 2,027 x 1.2 = 2,432 kcal per day to gain weight.

It is called a semi-daily or semidiurnal tidal pattern when the heights of the two highs and lows are roughly equal whereas a mixed semidiurnal tidal pattern is one in which the heights of the high and low tides vary. It is called a diurnal tide when areas have only one high and one low tide each day.
Since "diurnal" refers to a daily occurrence, a tide is said to be diurnal if there is just one whole tidal cycle every day. In the Gulf of Mexico, on Alaska's west coast, and in some regions of Southeast Asia, diurnal tides are typical.
Semidiurnal refers to "half of a day," and as one tidal cycle lasts for half a day, there are two full cycles per day. The majority of Europe, the west coast of Africa, the east coast of North America, and Australia all experience semi-daily tides.

Which term describes a mutation where a chromosome breaks, and its genetic material is reinserted in a different orientation?.
Chromosomal Inversions: An inversion occurs when a chromosome breaks in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome. Genetic material may or may not be lost as a result of chromosome breaks.
Inversion happens when a part of the chromosome breaks off, turn around, and becomes reaffixed. So, the order of the genes becomes reversed from what it was. While most cases of inversions go unnoticed and cause no gains or losses of DNA, they can lead to infertility or phenotypic reverberation.
An inversion can disrupt a gene, either by truncating the coding region of the gene or by placing its regulatory region far from the gene itself.
There are two kinds of Inversion mutation:
Pericentric Inversions- It happens when the centromere is included in the break. In other words, the break happens in the centre of the chromosome.
Paracentric Inversions- These occur when a chromosome breaks in one of its arms. In other words, the centromere is not incorporated.

What are the first three amino acids coded by this new mutated sequence
The first three amino acids coded by this new mutated sequence are Glutamine, Alanine, and Lysine.
One triplet nucleotide is coded for by one amino acid. Therefore, there are 16 nucleotides altogether following the insertion of the adenosine residue. The mRNA sequence will thus encode five amino acids. A codon is a collection of three nucleotides that are found in mRNA, and each codon designates an individual amino acid (hence, it is a triplet code). Thus, the chain of amino acids that makes up a protein is assembled in accordance with the template provided by the mRNA sequence and this is how Glutamine, Alanine, and Lycine form.
A gene encodes the amino acid composition of a polypeptide. The polypeptide's amino acid composition is determined by the bases in the gene's DNA. Proteins can either have a single polypeptide or many polypeptides linked together. All of a cell's or an organism's generated proteins are found in the proteome. A codon is a group of three DNA or RNA nucleotides that specify an amino acid or serve as a signal to cease protein production.

The right reason to why the P waves and S waves are not received in the shadow zone is because P waves are refracted and S waves are absorbed in the earth's outer core.
As they move further into the Earth's mantle, P waves and S waves move faster.
Curvilinear pathways are followed as they move through the Earth, but when they cross the barrier between substances in various states, they abruptly shift course.
However, P waves can go through the liquid outer core but S waves cannot. Because of the Earth's changing density, waves are refracted as they pass through it. As a result, the waves follow curved pathways. Refraction causes an abrupt shift in direction of the waves when they cross the boundary between two separate layers.
What are the differences between P waves and S waves?
P waves can pass through solids, liquids, and gases, but S waves can only pass through solids. The structure of Earth can be determined by scientists using this information.
