A cell can only grow so large in size, becauseA. its ability to exchange materials would happen more quickly as the cell grows.
B. its surface-to-volume ratio decreases as the cell becomes larger.
C. its surface-to-volume ratio decreases as the cell becomes smaller.
D. its ability to exchange materials is affected by a growing surface-to-volume ratio.

Answers

Answer 1
Answer: A cell can only grow so large in size because itsability to exchange materials is affected by a growing surface-to-volume ratio.Nature designed cells to be small in size because of the network of membranespassing through it. If cells grow any bigger, membranes in it will not be ableto pass through its different parts and perform their purpose.


A cell is a network composed of many organelles (e.g. mitochondria, nucleus),that communicate and work together to provide bodily functions. The cell issmall so that communication between organelles will be faster and much easier. Whencells are small they can be easily repaired when damaged and replicated whenneeded.
Answer 2
Answer:

Final answer:

A cell can only grow to a certain size because as it grows, its surface-to-volume ratio decreases, reducing the efficiency of material exchange between the cell and its environment. The larger the cell, the more challenging it is to exchange materials, hence a size limitation.

Explanation:

The reason a cell can only grow so large in size is due to the decrease in its surface-to-volume ratio as the cell becomes larger. This concept, often discussed in biology, refers to the relationship between the surface area of a cell (which determines the amount of substances that can be exchanged with the environment) and its volume (which determines the amount of substances required by the cell).

As the cell grows larger, its volume increases more rapidly than its surface area, reducing the ability of the cell to exchange materials efficiently. Thus, the correct answer is Option B: its surface-to-volume ratio decreases as the cell becomes larger.

Regular human body cells contain a total of 46 chromosomes. Therefore, because of meiosis, sperm cells contain ____ chromosomes.

Answers

Regular human body cells or somatic cells have a total of 46 chromosomes. Therefore, because of meiosis, sperm cells, which are gametes or sex cells must contain 1/2 of the number of total chromosomes found within a somatic cell, to make sure that the chromosome number within an organism is maintained, this would be 23 in this case.

What is the likely motivation for a person giving up soup after an extended illness? Values Habit Social interactions Positive associations Negative associations

Answers

Answer:

The correct answer is: Positive Associations.

Explanation:

  • Due to prolonged illness the person has lost all desire to survive.
  • This is the reason why he stopped consuming food.
  • Under such a situation, it is necessary that the person should be exposed to people who can positively counsel the person and make the ill person realise the importance of life.
  • It is necessary to make the person realise what he would gain if he chooses to survive and what he would lose if he chooses to die.
  • It is necessary to remind the person of all the possible goals he could achieve in his life if he chooses to survive.

Final answer:

A person may give up soup after an illness because they might develop a negative association with it. This is due to a psychological phenomenon called conditioned taste aversion, where the person associates the food with the unpleasant feelings of being sick.

Explanation:

The most likely motivation for a person to give up soup after an extended illness may be due to negative associations. After a long period of illness, a person may associate the consumption of soup with the period of sickness and, thus, develop aversion to it. This aversion could lead to the decision to stop consuming soup. This psychological phenomenon is also known as 'conditioned taste aversion'.

For example, imagine a person consumed a particular soup while sick for an extended time. Even after recovery, each time this individual thinks about or tries to eat that soup, it might trigger memories of being unwell. These negative emotions can be so strong that the person might steer clear of that soup in the future, despite soup being originally a comfort food or a staple in their diet.Remember, this is associated with our survival instinct—an evolutionary mechanism to prevent us from consuming harmful food substances that might have caused illness in the past.
