The answer is; The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them
The closer together two genes are on a chromosome, the higher the likelihood that they will be inherited together. This is referred to as genetic linkage. The higher the genetic linkage the lower the recombination frequency of the two genes.
The statement that 'The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them' is true regarding linkage. This is because genes close together are less likely to be separated during crossover in meiosis. Other statements provided about linkage are typically incorrect.
In the context of genetics, linkage refers to the phenomenon where genes that are located nearby each other on the same chromosome tend to be inherited together. Therefore, the correct statement regarding linkage from the provided options is:
The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.
This is because when genes are close together, they are less likely to be separated during crossover, a process that occurs during meiosis.
Note that not all traits that Mendel studied are due to genes linked on the same chromosome. Most genes are in fact not linked - they can independently assort during meiosis. Equally, linked genes are not found on different chromosomes, they are on the same one.
Lastly, the recombination frequency for two genes that are far apart from each other doesn't have a maximum of 100%. It typically peaks around 50%, which is an indication that the genes behave as if they are independently assorting.

I would also have to say B: those individuals whose traits give them an advantage in staying alive long enough to reproduce.....
I believe this is called natural selection. Hopefully this helps and good luck.
Those individuals whose traits give them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation. Hence, option B is correct.
Charles Darwin's theory of evolution by natural selection is based on the idea that individuals with advantageous traits have a better chance of surviving and reproducing, passing those traits on to their offspring.
Over time, this process leads to the accumulation of beneficial traits in a population, ultimately resulting in the adaptation and diversification of species. Darwin's observations and studies, including his famous work on the Galápagos Islands, provided evidence supporting this principle of natural selection.

it occurs in every body cell.
Answer:
The correct answer would be hybridization.
Hybridization refers to the process by which organisms of different breed, species, or varieties are selectively interbred in order to produce offspring with desired characters.
Similarly, Maltese dogs were selectively bred in order to attain characters like the small size, less shedding of hairs et cetera.

Severe weather signifies any threatened meteorological occurrence with the likelihood to cause serious social disruption, destruction, or loss of human life. The kinds of severe weather phenomenon differ, on the basis of altitude, latitude, atmospheric conditions, and topography.
Hail, high winds, wildfires, and excessive precipitation are the kinds and influences of severe weather, likewise, tornadoes, thunderstorms, cyclones, and others are. The key variables that influence that how the weather will behave are temperature, air pressure, and density of the air.
The movement of water from an area of high water concentration to an area of low water concentration is known as osmosis. Diffusion is also one such mechanism in which particles move from high concentration to low concentration. But, there is a difference between diffusion and osmosis. In osmosis, the movement occurs through a semi-permeable membrane. In cells, plasma membrane acts as semi-permeable membrane. Osmosis is a very important phenomenon to sustain life in biological systems because it helps in maintaining homeostasis. Homeostasis on the other hand is a process which aids living beings in regulating their daily activities so as to maintain stable internal environment. For example, if a cell becomes dehydrated (flaccid cell), then it can be easily rehydrated by keeping it in an environment full of water i.e. a hypertonic solution . The water will enter into the cell by osmosis thereby making it rehydrated again.
