Answer:

Microscopically, a single crystal has atoms in a near-perfect periodic arrangement; a polycrystal is composed of many microscopic crystals (called "crystallites" or "grains"), and an amorphous solid (such as glass) has no periodic arrangement even microscopically.

Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. ... The third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. Examples of amorphous solids include glass, wax, and many plastics.

In condensed matter physics and materials science, an amorphous (from the Greek a, without, morphé, shape, form) or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used synonymously with glass.

Explanation:

This chapter highlights mesocrystals as an interesting example of particle‐mediated, non‐classical crystallization processes. Mesocrystals — the shortened name for mesoscopically structured crystals — are superstructures composed of nanoparticles, being arranged three‐dimensionally in crystallographic register. Mesocrystals are often only intermediate structures in a non‐classical crystallization pathway leading to a final single crystal by nanoparticle fusion. Therefore, they are difficult to detect. Although mesocrystals were initially described for synthetic systems, recent investigations have revealed an increasing number of bio‐mineral systems which appear to be mesocrystals, but which so far have been considered to be single crystalline, including nacre and sea urchin spines. This chapter briefly defines non‐classical crystallization processes, provides some examples of synthetic mesocrystals and mesocrystals in biomineralization, and attempts to provide some insight into their formation mechanisms, despite their being as yet largely unexplored.

The origin of the galactic coordinate system points towards the center of the galaxy rather than towards the vernal equinox. The celestial and ecliptic coordinate systems have their point of origin towards the Vernal Equinox. The equatorial coordinate system doesn't exist.

Answer:

The Circulatory system has two organs the heart, and blood vessels. The heart pumps blood and the blood is carried away and back through blood vessels like capillaries, veins, and arteries. The Circulatory system works with the Respiratory system by carrying the oxygen that is brings in, and takes away the carbon dioxide to the Excretory system. The Circulatory system helps the Excretory system by bringing waste, and carbon dioxide to kidneys, and liver I believe it might be a different organ but I know the kidneys for sure.

The Nervous system consists of three organs the spinal cord, brain, and nerves. The two systems are the Central Nervous system is made up of the the brain, and spinal cord. The Peripheral system is made up of the nerves, which branch off from the spinal cord to all parts of the body. The Central Nervous system sends a jolt of electricity from the brain through the spinal cord to the nerves that branch of it to all parts of the body so that we can move. The Nervous system helps the Digestive system by sending electricity to the nerves so that we can swallow our food and so that we can digest our food. The Nervous system helps the Excretory system by detecting any changes in the salt levels in the blood through the urine in the Excretory system. By providing the brain with a constant supply of oxygen rich blood the Circulatory system helps the Nervous system, so the Nervous system regulates the heart rate and blood pressure. So that the Nervous system can regulate the Respiratory rate, and monitor the blood gas levels the Respiratory system supplies oxygen, and removes carbon dioxide.

The Excretory system consists of five organs the Large Intestine, Liver, Lungs, Kidneys, Skin. The Excretory system helps the Digestive system by getting rid of the waste it produces. The circulatory system helps the Excretory system by giving the kidneys, and the other organs in the Excretory system blood, and carry carbon dioxide from cells to the kidneys.

The Respiratory consists of five organs Lungs, Larynx, Trachea, Pharynx, and Bronchi. The Respiratory system provides the body with oxygen, and allows us to breath.

The Digestive System consists of nine organs, the Mouth, Esophagus, Stomach, Pancreas, Liver, Gallbladder, Small Intestine, Large Intestine, and the Anus. The Digestive system dissolves food and turns them into nutrients for cells, to give them energy, use for growth, and cell repair.

Answer:

C) Sodium ions

Answer:

1) Option b is correct. a founder effect

2) Option a is correct. keeping the sex ratio as close to 50:50 as possible

Explanation:

The exposed situation is an example of an ex-situ conservation program. These programs are planned to keep and restore the population of species that are in danger of extinction. There are many challenges associated with captivity, and one of them is related to maintaining genetic diversity in the population.

1) Introducing a few animals of an endangered species into the zoo might be considered an example of the founder effect. Just a pregnant female is enough for it to occur. And the most significant problem associated with this event is the loss the genetic diversity or variability. When breeding animals in captivity there is a high risk of losing some genes and fixating others, due to inbreeding.    

Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect-. In founder effect, a new population originates when a few individuals, coming from a bigger-sized population and carrying their genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.

2) When selecting the animals that are being kept in captivity, it is significant to consider a few aspects concerning genetic diversity maintenance. The main objective is to prioritize the original genetic material.

Answer:

The frequency of the population that are carriers is 0.284 or 28.4%

Explanation:

According to Hardy-Weinberg equilibrium equation, p² + q² + 2pq = 1

Also, the sum of the allele frequencies for all the alleles at the locus, p + q = 1.

Where where p is the frequency of the dominant allele and q is the frequency of the recessive allele in the population.

p² = dominant h0m0zygous genotype frequency

2pq = heterozygous genotype frequency

q² = recessive h0m0zygous genotype frequency

From the given data; the dominant h0m0zygous genotype, i.e., the proportion of an African population that are susceptible to Malaria, p² = 0.688

p = √0.6880 = 0.829

But p + q = 1; q = 1 - p

Since p = 0.829, q = 1 - 0.829

q = 0.171

Frequency carriers for Sickle Cell allele, i.e., the heterozygous genotype = 2pq

Frequency of carriers = 2 × 0.829 × 0.171 = 0.284

Therefore, the frequency of the population that are carriers is 0.284 or 28.4%

Living things are shielded from harmful UV radiation by ozone inside the upper atmosphere, which keeps the sun's rays from reaching the planet's surface.

The colorless, odorless reactive atmosphere known as ozone is created when three oxygen atoms combine. It can be found in nature blocking UV radiation that can damage the planet's life in the troposphere of the atmosphere.

The atmospheric ozone layer in the stratosphere absorbs some of the solar radiation, preventing it from reaching the planet's surface. The main UVB energy that it absorbs is this kind of UV light. Numerous harmful effects are associated with UVB, a kind of ultraviolet rays emitted by the sun including sunlamps.

Answer:

The Newton's three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion.

Explanation:

Answer: Hope This Helps!

Explanation:

Newton's First Law of Motion:

Newton's First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it. Similarly, if the object is at rest, it will remain at rest unless an unbalanced force acts upon it. Newton's First Law of Motion is also known as the Law of Inertia.

Basically, what Newton's First Law is saying is that objects behave predictably. If a ball is sitting on your table, it isn't going to start rolling or fall off the table unless a force acts upon it to cause it to do so. Moving objects don't change their direction unless a force causes them to move from their path.

As you know, if you slide a block across a table, it eventually stops rather than continuing on forever. This is because the frictional force opposes the continued movement. If you threw a ball out in space, there is much less resistance, so the ball would continue onward for a much greater distance.

Newton's Second Law of Motion:

Newton's Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will need to be to cause it to accelerate. This Law may be written as force = mass x acceleration or:

F = m * a

Another way to state the Second Law is to say it takes more force to move a heavy object than it does to move a light object. Simple, right? The law also explains deceleration or slowing down. You can think of deceleration as acceleration with a negative sign on it. For example, a ball rolling down a hill moves faster or accelerates as gravity acts on it in the same direction as the motion (acceleration is positive). If a ball is rolled up a hill, the force of gravity acts on it in the opposite direction of the motion (acceleration is negative or the ball decelerates).

Newton's Third Law of Motion:

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.

What this means is that pushing on an object causes that object to push back against you, the exact same amount, but in the opposite direction. For example, when you are standing on the ground, you are pushing down on the Earth with the same magnitude of force that it is pushing back up at you.

Answer:

Since glycolysis of one glucose molecule generates two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, 10 NADH molecules, and two FADH2 molecules per glucose molecule

The products of glycolysis alone are not sufficient to directly drive the citric acid cycle (also known as the Krebs cycle or the tricarboxylic acid cycle).

However, the output of glycolysis, specifically pyruvate, is a crucial substrate that enters the mitochondria, where it undergoes further processing before entering the citric acid cycle.

The energy carriers, specifically NADH and FADH2, play a crucial role in driving the electron transport chain, the final step of cellular respiration.

The electron transport chain uses the energy from NADH and FADH2 to generate a large amount of ATP through oxidative phosphorylation.

Thus, while the products of glycolysis do not directly drive the citric acid cycle, they contribute to the overall energy production and supply the necessary substrates, such as acetyl-CoA, which is essential for the initiation of the citric acid cycle.
