Which of the following statements is true? Linked genes are found on different chromosomes. The observed frequency of recombinat

ion of two genes that are far apart from each other has a maximum value of 100%. Crossing over occurs during prophase II of meiosis. The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.

The correct answer is option The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.

In case, two genes are present in very close proximity to one another, they would represent the phenomenon of linkage. Due to the the presence of the linkage between the two closely related genes, the crossing over between them would not occur. As the distance between the two genes is decreased, the linkage becomes more strong and reduced the chances of the crossing over. Hence, it can be said that the chance of the crossing over between two genes varies according to the distance between them.

List several important provisions from the oceans.
Leto [7]

Answer:

the ocean provides several important resources to its inhabitants

Explanation:

The majority of biomass in any ocean consists of microscopic organisms such as phytoplankton which are pivotal to aquatic ecosystems. These microorganisms are able to thrive in their habitat due to incredibly dense populations of the bacteria <em>phackingyurmom aquatica </em>present in most oceans. These bacteria provide a wide spectrum of vital nutrients. As a result many of the aforementioned microorganisms love <em>phackingyurmom</em>.

Describe the function of sodium and potassium in the generation of an action<br> potential.
larisa [96]

Answer:

The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.

Answer:

Transmission electron microscope (MET): allows sample observation in ultra-thin sections. A TEM directs the electron beam towards the object to be increased. A part of the electrons bounce or are absorbed by the object and others pass through it forming an enlarged image of the specimen. To use a TEM, the sample must be cut into thin layers, not larger than a couple thousand thousands of angstroms. A photographic plate or a fluorescent screen is placed behind the object to record the enlarged image. Transmission electron microscopes can increase an object up to a million times.

A scanning electron microscope creates an enlarged image of the surface of an object. It is not necessary to cut the object into layers to observe it with an SEM, but it can be placed in the microscope with very few preparations. The SEM scans the image surface point by point, unlike the TEM, which examines a large part of the sample each time. Its operation is based on traversing the sample with a very concentrated beam of electrons, similar to the scanning of an electron beam on a television screen. The electrons in the beam can disperse from the sample or cause secondary electrons to appear. Lost and secondary electrons are collected and counted by an electronic device located on the sides of the specimen. Each point read from the sample corresponds to a pixel on a television monitor. The higher the number of electrons counted by the device, the greater the brightness of the pixel on the screen. As the electron beam sweeps the sample, the entire image of it is presented on the monitor. Scanning electron microscopes can enlarge objects 200,000 times or more. This type of microscope is very useful because, unlike TEM or optical microscopes, it produces realistic three-dimensional images of the object's surface.
