What is the evidence that chiasmata are points of physical exchange between chromatids?.
Knobs and translocations are the evidence that chiasmata are points of physical exchange between chromatids.
Cytological indicators like as knobs and translocations have been used to demonstrate that there is a physical exchange of chromosome arms during meiosis. The chiasma is a structure that arises between two homologous chromosomes by crossover recombination and physically connects the two chromosomes during meiosis.
It is particularly important to develop during cell division because it aids in the attachment of chromosomes to opposing spindles. Chiasmata assist chromosomes in appropriately dividing. If there are chiasmata during metaphase I of meiosis, the alignment will be correct. Thus, these two evidence point to physical changes between chromatids in meiosis.

Who discovered type A and type B personalities?Two cardiologists are credited with developing the type A and type B personality theories. Meyer Friedman and RH Rosenman conducted research on potential coronary disease causes in the 1950s. Friedman and Rosenman created a system for classifying individuals as either type A, type B, or type AB after conducting a nine-year study of approximately 3,000 healthy males between the ages of 35 and 59. (for those who defied easy categorization).
What were their conclusions made by them?They concluded that those with type A personalities are more prone to be preoccupied with status and success. They are frequently compulsive workers who could struggle with impatience and low self-esteem. Additionally, they are more likely to lash out quickly. Unsurprisingly, Friedman and others have identified this personality type that has been linked to an increased risk of heart disease. People with type B personalities are more likely to be tolerant and even-tempered, and they also report higher levels of life satisfaction.

A channel protein, but not a carrier protein, can exist in a open configuration creating a pore through a membrane. True or false?.
The given statement is true.
On one side of the membrane, carrier proteins bind to molecules or ions and release them on the opposite side.In order to allow target molecules or ions to diffusely pass through the membrane without interfering with one another, channel proteins make holes/pores that permeate the membrane.The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane.In contrast, channel proteins have significantly weaker interactions with the solute being conveyed.While some channel proteins are always open, others are "gated," which means that they respond to a specific stimulus to either open or close the channel (like an electrical signal or the binding of a molecule).Transport proteins known as channel proteins contain a hydrophilic channel via which specific molecules or ions can pass across the membrane (Ex: aquaporins for water). Transport proteins known as carrier proteins bind to molecules and modify their structure to move them across the membrane.Learn more about channel protein here:

which provides long term energy storage
Answer: Glycogen
Explanation:
It provides long-term energy storage.
Further Explanation
Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.
Energy source in animals
Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.
Energy source in plants
In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.

Answer:
Cohesion and capillary action
Explanation:
Cohesion and capillary action are the answers. Cohesion is the attraction of water to water. Capillary action is when water travels up without something helping or propelling it. So, using cohesion, the liquid in the example is attracted to itself and sticks together. Capillary action occurs, making the stuck- together liquid travel up the straw and be higher than the liquid in the cup.

How does a prism separate white light into the different colors that compose it?.
The prism separates white light into the different colors that compose it, as white light passes through a prism, shorter wavelengths refract more than longer wavelengths, and the colors separate.
Visible light commonly referred to as white light is made up of several different colors. It is common to see these hues as light travels through a triangular prism. The white light is broken down into its component colors—red, orange, yellow, green, blue, and violet—as it passes through the prism. Dispersion is the division of visible light into various colors.
Each wavelength of light is refracted by a slightly different amount when it travels through a prism due to the angles and planar faces of the object. The most refracted color and one with the highest frequency is violet. Red is refracted the least and has the lowest frequency. White light is spread out and divided into the colors of the spectrum as a result of how differently each hue is refracted, which causes each color to bend at a different angle.

The correct answer is because MSD2 an apoplastic regulates ROS distribution during root skotomorphogenesis it plays an important role in plant growth and development.
MSD2 expression in roots is light condition dependent, implying that MSD2 may influence ROS metabolism in roots during the light-to-dark transition. ROS distribution, which exhibits an opposite gradient of H2O2 and O2radical dot in etiolated msd2 mutants and is accompanied by changes in the onset of differentiation, governs root architecture. MSD2 is secreted and has SOD activity that can be inhibited by tyrosine 68 nitration. Although membrane-localized NADPH oxidases are well known for producing ROS during developmental and stress responses, the metabolic pathways of the superoxide (O2radical dot) produced by them in the apoplast are poorly understood, and the identity of the apoplastic superoxide dismutase (SOD) in Arabidopsis is unknown.
