How does a single-cell organism get oxygen and food?
A single-cell organism obtains oxygen through simple diffusion across its cell membrane. It acquires food by engulfing or absorbing organic molecules from its environment. These nutrients are then used for energy and growth.
What happens if there is an excess of cholesterol in the cell membrane?
An excess of cholesterol in the cell membrane can lead to decreased fluidity and flexibility of the membrane, potentially affecting the cell's ability to function properly.
How is cancer cell growth different from normal cell growth?
Cancer cell growth is different from normal cell growth because cancer cells divide uncontrollably and do not respond to signals that regulate cell growth and death. This uncontrolled growth can lead to the formation of tumors and the spread of cancer to other parts of the body.
Does every cells needs oxygen and nutrients?
Yes, every cell in the body requires both oxygen and nutrients to survive and carry out its function. Oxygen is needed for cellular respiration to generate ATP, the cell's energy source, while nutrients provide the building blocks for cell growth and maintenance. Without a constant supply of oxygen and nutrients, cells would not be able to function properly and would eventually die.
How does the Oxygen get from the interstitial fluid to the inside of the cell?
Oxygen diffuses from the interstitial fluid into the cell through the cell membrane. This process occurs due to a concentration gradient, where oxygen moves from an area of higher concentration (interstitial fluid) to an area of lower concentration (inside the cell). Once inside the cell, oxygen is used in cellular respiration to produce energy.
What causes increased gh secretion?
excess cell growth and division
What problems do cell growth cause?
Uncontrolled cell growth can lead to tumors and cancer. It can also disrupt tissue function and cause organ enlargement or dysfunction. Additionally, rapid cell growth can deplete resources and lead to nutrient or oxygen deprivation in surrounding tissues.
What is a that cell division solves the problem of cell growth?
cell division increases the mass of the original cell.
What is the continued increased metabolism that occurs in a cell to remove excess lactic acid that resulted from exercise?
oxygen debt
Is not related to a cells ratio of surface area to volume?
cell size rate of growth number of nuclei efficency of cell's transport of oxygen efficiency of cell's transport of nutrients
Why do cats breathe?
The same reason all land animals breathe, to take in oxygen for cell growth and repair.
In 1961 Procter and Gamble introduced what shampoo which used zinc pyrithione to stop the excess cell growth on your scalps that leads to dandruff?
Head and Shoulders
How does a single-cell organism get oxygen and food?

Which is not a way that cell division solves the problems of cell growth?
Cell division helps in solving the problem of cell growth by allowing cells to replicate. This ensures that genetic material is distributed equally between daughter cells. However, cell division does not solve the problem of accumulation of waste products within the cell. This issue is addressed by different cellular waste management processes like autophagy.
What hematopoietic growth factor controls red blood cell synthesis and what organ release it?
Erythropoietin is the hematopoietic growth factor that controls red blood cell synthesis, and it is released mainly by the kidneys in response to low oxygen levels in the blood.
What happens if there is an excess of cholesterol in the cell membrane?
An excess of cholesterol in the cell membrane can lead to decreased fluidity and flexibility of the membrane, potentially affecting the cell's ability to function properly.
What if a cell receives no oxygen or food?
The cell would die. A cell is just like you. A cell can not live with out oxygen or food!
