What is Aerobic respiration?The respiration in which glucose molecules produces energy in the form of ATP is called aerobic respiration.
The aerobic respiration produces 36 ATP molecules. Fermentation will produce lactic acid. Aerobic respiration consists of three stages such as glycolysis, ETC cycle.
The conversion of fuel, such as fats and sugars, into chemical energy is known as aerobic respiration. Anaerobic respiration, in contrast, doesn't require oxygen.
Therefore, Aerobic respiration will yields 36 ATP molecules and starts with the process of glucose molecules.

1. Explain five challenges involved in mobilizing deposits from
the poor.
Answers
Mobilizing deposits from the poor poses several challenges, including lack of documentation, limited financial literacy, inadequate access to banking services, informal financial practices, and mistrust in formal financial institutions.
Mobilizing deposits from the poor can be challenging due to various factors.
First, many individuals in impoverished communities may lack proper documentation such as identification cards or proof of address, which are often required by formal financial institutions to open accounts. This can hinder their ability to access banking services and deposit their savings.
Second, there is often limited financial literacy among the poor, making it difficult for them to understand the benefits and processes of depositing money in formal institutions.
Third, in many underserved areas, there is a lack of accessible banking services, with banks being located far away or having limited outreach programs, making it inconvenient for the poor to deposit their money.
Fourth, informal financial practices, such as savings groups or rotating savings and credit associations, may be prevalent in these communities, leading individuals to rely on these systems instead of formal banking channels.
Finally, there may be a general mistrust or skepticism towards formal financial institutions due to past experiences or perceptions of exclusion, making it challenging to encourage deposit mobilization among the poor. Overcoming these challenges requires innovative approaches, such as mobile banking solutions, financial education programs, and building trust through community engagement.

Natural selection has been the factor that includes the differential survival of the adapted individual. It may stop the decline of the Cheetah due to climate change, and habitat destruction.
What is natural selection?Natural selection is defined as the preference procedure that allows the adapted organism to survive and reproduce to the change in climatic conditions. It has been part of the evolution.
The decline in the cheetah population is difficult to stop as the climatic conditions have changed a lot and the habitats of the organisms have been destructed at a larger rate. Hunting by humans for their skins and claws has increased over years.
The genes of the cheetah population have been one of the factors that hinder their natural selection. This all together possesses a threat to the cheetah population.

_____: the sudden, temporary reversal of the difference in charge between the inside and outside of a neuron
Answers
Depolarization: This occurs when there is a rapid and temporary reversal of the electrical charge across the cell membrane of a neuron, leading to a brief increase in the membrane potential.
During depolarization, the inside of the neuron becomes more positively charged than the outside due to the influx of positively charged ions such as sodium (Na+) into the cell. This change in charge can trigger the opening of voltage-gated ion channels, leading to an action potential that propagates down the length of the neuron.
Depolarization is a crucial step in the process of neuronal communication and plays a role in various physiological processes such as muscle contraction, sensory perception, and cognitive function. Dysregulation of depolarization can lead to a variety of neurological disorders.

Answers
The spinal cord itself is shorter than the vertebral column, option A is correct.
The spinal cord is a long, thin, tubular bundle of nervous tissue that extends from the base of the brain and runs through the vertebral canal formed by the vertebral column. While the vertebral column is composed of 33 individual vertebrae stacked on top of one another, the spinal cord does not extend the entire length of the column.
Instead, it typically terminates around the first or second lumbar vertebra, leaving a considerable gap between its end and the lower part of the vertebral column. This gap is known as the cauda equina, which consists of a collection of nerve roots that continue down to the lower back and serve the lower limbs and pelvic organs, option A is correct.

what is the tolerance is interval for the 5 ml pipettes? The 25 ml
pipette?
Answers
The tolerance interval for the 5 ml pipette is ± 0.05 ml, while the tolerance interval for the 25 ml pipette is ± 0.15 ml. The pipette is a laboratory instrument used to transfer small volumes of liquid accurately from one container to another. Pipettes come in a variety of sizes, but the most common sizes are 5 ml and 25 ml.
Tolerance is the permissible variation from a specific value that an instrument or product may have. When it comes to pipettes, tolerance is critical because a small variation in the volume of liquid transferred can significantly affect the outcome of an experiment.
The tolerance interval for a pipette indicates the maximum allowable error or deviation from the nominal volume (the expected volume) for a pipette to be considered accurate. The tolerance interval for a 5 ml pipette is ± 0.05 ml, while the tolerance interval for a 25 ml pipette is ± 0.15 ml. This implies that the actual volume transferred can vary by up to ± 0.05 ml and ± 0.15 ml, respectively.

what is a mature virus outside the host cell called? (2 terms)
Answers
A mature virus outside the host cell can be referred to as either a virion or a viral particle. A virus is a microscopic infectious agent that replicates inside living cells of an organism.
The process of virus replication involves the virus infecting a host cell, using its machinery to replicate itself, and then releasing newly formed viruses to infect other cells. Once the virus has completed its replication cycle and has been assembled and packaged within the host cell, it is released from the host cell and can be referred to as a mature virus or viral particle.
A virion is the complete infectious unit of a virus, consisting of the virus's genetic material (DNA or RNA) encased in a protein shell called a capsid. Some viruses also have an outer lipid envelope surrounding the capsid. The virion is the infectious form of the virus that can transmit the virus from one host cell to another.
