A parent cell divides according to the image shown below. What differences in structure and behavior would you expect from Cell A and Cell B?
The daughter cells have a different number of chromosomes what is an indication of failure in the motitic division, thats because during division the parent cell have to duplicate the genetic material to pass for the next generation in equal number, since this is important to maintain the cellular integrity, as weel as the characteristics of the cellular species. The Cell A is an identical copy of the parent cell (somatic cell), having the same traits and functions, as well as a normal cellular activity, while Cell B have only half of the genetic information of the mother cell, this cell more close to an sex cell than a somatic cell, numerically speaking, since the fact of it having 1/2 of the information makes it more difficult to perform its cellular functions as a somatic cell.

Which of the following processes occurring during meiosis helps to produce and maintain genetic variation in natural populations? Choose the best answer.DNA replicationcrossing overfertilizationlinkage
Crossing over is the mechanism that occurs during meiosis in order to produce and maintain genetic variation in natural populations.
Crossing over is the event that takes place in the pachytene stage of the Prophase I of meiotic cell division. It is the process where the exchange of the genetic material takes place between the two non-sister chromatids of the homologous chromosomes.
Meiosis is the type of cell division that results in the formation of daughter cells from one single parent cell. The number of chromosomes are halved in the daughter cells and therefore it is named as the reductional division. Meiosis can be accomplishes in two parts: meiosis I and meiosis II.

which has a greater contractile velocity? type I or type II fibers?
Type II fibers have a greater contractile velocity compared to Type I fibers. This is because Type II fibers contain more myosin ATPase, which is an enzyme responsible for breaking down ATP to generate energy for muscle contraction.
Type II fibers also have a larger cross-sectional area and a higher concentration of fast-twitch muscle fibers, which allows them to produce more force and contract more quickly than Type I fibers. However, Type I fibers have greater endurance and are more resistant to fatigue due to their high oxidative capacity and slow contraction speed.

the tympanic membrane connects to three tiny bones that, in turn, transmit the vibrations to the ____.
The tympanic membrane connects to three tiny bones (the malleus, incus, and stapes) that, in turn, transmit the vibrations to the cochlea.
The cochlea is a spiral-shaped organ located in the inner ear of humans and other vertebrates that plays a crucial role in hearing. It is filled with fluid and contains thousands of tiny hair cells that are responsible for converting sound waves into electrical signals that the brain can interpret as sound.
When sound waves enter the ear canal, they cause the eardrum to vibrate. These vibrations are transmitted through the bones of the middle ear to the cochlea, where they cause the fluid inside to move. This movement stimulates the hair cells, which then generate electrical signals that are sent to the brain via the auditory nerve.
The cochlea is divided into three sections: the scala vestibuli, the scala media, and the scala tympani. The scala media is where the hair cells are located, and it is separated from the scala vestibuli and the scala tympani by a thin membrane called the basilar membrane.

In an early experiment, it was found that a mouse in a sealed glass jar soon died, but if a plant was included in the jar, the mouse lived much longer. Explain theses results.
Answer:
The correct answer is - mouse produces carbon dioxide which is used by the plants for photosynthesis that in turn produces oxygen that is used for cellular respiration.
Explanation:
A mouse can not live in a sealed container or jar for a long time whereas with a plant in a closed and sealed jar mouse can live longer. This is due to the fact that in absence of the plant there is no oxygen for the mouse to get perform cellular respiration.
in a jar with a plant, the mouse lives longer because the plant still produces oxygen by the process of photosynthesis which is used by the mouse for cellular respiration and produces carbon dioxide that is taken by the plant.
