Research on Hemisphere specialization of the intact brain patients resulted in the understanding of the relative speeds of verbal and virtual-spatial processing in the two hemispheres.
Based on their findings and research in patients with intact brain, hemisphere research has resulted into the discovery of what part of the brain serves a particular function. Researchers thought that the left hemisphere was the dominant hemisphere in which all higher brain activities, such as thinking and problem solving, occurred. The right hemisphere was often assumed to have no specific functions or talents.
According to the current view of hemispheric specialization, the left hemisphere is better at verbal processing activities while the right hemisphere is better at nonverbal processing tasks. This shift in viewpoint was prompted by research into the impacts of split-brain surgery.

A mineral that has no particular planes of weakness in its lattice structure, so it does not break along particular planes. What happens when this mineral is struck?.
A mineral has no particular planes of weakness in its lattice structure, so it does not break along particular planes. Fracture is what happens when this mineral is struck.
An organized collection of points that characterizes a crystal-forming particle's structure is known as a lattice structure. The lattice points help identify a crystal's unit cell. In the sketched structure, every particle (yellow) is the same.
The face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal closest packed are significant lattice structures.
Because of the structural positions of atoms and ions in the crystal, cleavage is the tendency of minerals to split along crystallographic planes, resulting in planes of relative weakness.
While a break occurs when the rock shows no evidence of a plane of weakness. In the event that the break is clean, parallel, and has reflective surfaces, it can be distinguished from a fracture.

The unit discusses the mass abundance of water on our planet and in our oceans which is a stark contrast to Sedlak’s highlighting massive droughts and cities in danger of having no drinking water. Briefly explain the reason that Sedlak gives for water shortages.
According to Sedlak, there are factors that contribute to water shortages.
One is the population .
Two is the climate change.
What is Drought?A drought is a period of time when an area or region experiences below-normal precipitation.
The amount of precipitation at a particular location varies from year to year, but over a period of years the average amount is fairly constant.
These are two major changes that have occurred over the past couple of years.
Sedlak gave reasons for water shortages which is that the population has clearly increased dramatically, which means more people need access to water to survive.
The second impact is the climate change.
Climate changes can cause drought which in effect means no water coming in to replace any previous ones.
In conclusion, the beginning of a drought is most times difficult to determine owing to the fact several weeks, months, or even years might pass before people know that a drought is occurring.

What is the name for amount of energy that a reaction needs to get started?
The amount of energy that a reaction needs to get started is activation energy and is used by the substrate to form products.
The enzymes are the biocatalysts that are required to increase the rate of reaction because they help in the lowering of the threshold or minimum energy which is called activation energy which is used by the substrate to form the products and if that activation energy is very high that cannot be passed by the substrate then
enzymes help to reduce it by joining with the substrate so activation energy is the amount of energy required by a reaction or substrate to get started and this energy is measured in the joules per minute, kilojoules per mole and kilocalories per mole and activation energy is calculated using k = Ae -Ea / RT where k is rate constant, A is the pre-exponential factor, Ea is activation energy and it has the same unit as R*T, R is the universal gas constant and T is the absolute temperature in kelvins and the example of activation energy is turning the key which causes the spark which activates the burning of gasoline in the engine.
The enzyme which has the maximum capacity of lowering the activation energy and increasing the maximum rate of reaction is known as carbonic anhydrase enzyme forming almost 6000 products per second.

In which process does a solute bind to a carrier in the plasma membrane that then changes shape and releases the solute to the other side of t?
Facilitated diffusion is the process where a solute bind to a carrier in the plasma membrane that then changes shape and releases the solute to the other side of the membrane.
What is carrier-mediated diffusion?In carrier-mediated diffusion, Polar molecules including simple sugars, simple carbohydrates, and amino acids are transported across the membrane by carrier-mediated diffusion, the carrier protein, which actually alters form in the process, is responsible for this.
There are three mechanisms of carrier-mediated transport;
1. Facilitated diffusion: Solutes diffuse across transport proteins in the plasma membrane when their diffusion is facilitated. A form of passive transport is facilitated diffusion. Because the solution is flowing down the concentration gradient, passive transport is still occurring despite the presence of transport proteins in assisted diffusion.
2. Primary active transport: Primary active transport, also known as direct active transport, employs chemical energy (such as that from the cell membrane's adenosine triphosphate or ATP) to move all types of solutes against their concentration gradient across a membrane.
3. Secondary active transport-It is known as secondary active transport when a solute is transported in the direction of its rising electrochemical potential while a second solute, typically an ion, is spread out more readily in the direction that its electrochemical potential is lowering.

Which of these does mRNA do in eukaryotic cells but not prokaryotic cells?
A. duplicate itself
B. cross a membrane
C. coil into a compact crystal form
D. break off some of its phosphates to release energy
In the case of prokaryotic cells, the mRNA does not need to cross a nuclear membrane. So the correct option is B.
What is prokaryotic mRNA?The kind of mRNA produced by transcription in prokaryotes is known as prokaryotic mRNA. In most cases, RNA polymerase is in charge of turning genes into mRNA molecules. Prokaryotic mRNA's primary characteristic is polycistronic, however.
As a result, a single mRNA molecule comprises a number of structural genes that are members of a certain operon. As a result, many locations for the start and termination of polypeptides exist inside the same mRNA molecule. This explains how several kinds of proteins may be made by a single bacterial mRNA molecule.
Prokaryotes also usually combine transcription and translation. While a result, bacterial mRNA translation begins as the DNA template is now being transcribed. Therefore, post-transcriptional changes to bacterial mRNA molecules are quite limited. They frequently undergo rapid ribonuclease degradation, shortening bacterial mRNA's half-life.
Therefore the correct option is B.

if you have a group of individuals that are all clones or each other (i.e. all individuals are genetically identical), but all individuals are phenotypically different, what is the estimated heritability
The estimated heritability by comparing individual phenotypic variation among related individuals in a population
Individual phenotypic variance across related individuals in a population is compared to assess heritability, as is the relationship between individual phenotype and genetic information, or even the modelling of summary-level data from genome-wide association studies (GWAS).Historically, twin studies have been used to estimate heritability. Fraternal twins typically share 50% of their DNA, compared to identical twins, who have essentially no genetic differences. When identical twins and fraternal twins are raised together in the same environment and a trait between them appears to be more similar, genetic factors most likely play a significant part in defining that feature. Researchers can measure a characteristic's heritability by comparing identical twins to fraternal twins for that trait.To learn more about heritability.

Ayumi can she explain why the land cools faster than the sea by saying that water retains heat longer than other substances; option B.
What is the reason why land cools faster than the sea?The process of cooling and heating of a substance depends on the conducting ability of the substance.
Substances that are good conductors of heat are heated up faster and also cool down faster whereas, substances that are poor conductors of heat are heated up slowly and also cool down slowly.
Comparing the conducting ability of solids and liquids shows that solids are generally better conductors of heat than liquids.
Therefore, land is a better conductor of heat than the water in the sea.
Land will thus heat up faster and cool down faster than the sea. This implies that water will retain heat more as it is heated up more slowly

onycholemmal carcinoma is believed to be of trichilemmal origin, and shows differentiation similar to that found in the trichilemmal portion of the hair follicle. less then 3 cases are currently in the english literature. all reported cases presented in elderly patients and were without recurrence after amputation. clinical presentation has been varied and can be very subtle. as with most nail tumors, pain is not a common feature. the diagnosis is based on the histology showing an infiltrative growth of atypical keratinocytes, one or more foci of abrupt keratinization, and usually also keratinous cysts devoid of a granular layer. when a cystic component and clear cells predominate, the subtype description of malignant proliferating onycholemmal cyst has been applied. no standard treatment option or follow up has been established.
Rarely, "malignant proliferating onycholemmal cyst" and "onycholemmal carcinoma (OC)" have been used to characterize subungual malignant epithelial tumors with tricholemmal keratinization.
In addition to a nail bed carcinoma with tricholemmal microcysts, we also present a case of a slow-growing OC that developed on the middle finger of a 58-year-old male. This case was remarkable because it had sebaceous-apocrine differentiation.
Therefore, we believe that OC is a less appropriate name to describe this condition than microcystic nail bed cancer.
None of the uncommon cases of OC are known to match the additional traditional criteria for tricholemmal carcinoma provided by Headington, namely lobular organization, peripheral palisading, thicker basement membrane, and glycogen-positive tumor cells.
