Answer:
The factors limiting the size of cells include: Surface area to volume ratio (surface area / volume) Nucleo-cytoplasmic ratio. Fragility of cell membrane.
Explanation:
mark me as brainliest pls :)
Emotional intelligence helps one regulate internal stress through:
Self - managment - take intitiative, control impluses, adapt to circumstances.
Self - awareness - recongize your emotions and how they affect your thought and behavior.
Relationship managment - know how to develop relationships, manage conflict, inspire and influence others.
Social - awareness - understand concerns and needs of others, and can pick up on emotional cues.
The answer is cellular aging theory. This theory focuses on the ways then that the molecules as well as the cells are being affected by aging and the passage of time. Aside from this theory there are 2 more theories of aging namely the genetic theory and the wear and tear.
Answer:
CO2
Explanation:
Diffusion is a simple process of molecular movement, from their higher concentration to the area with their lower concentration. The process of CO2 movement from the pulmonary capillaries into the alveoli is part of the gas exchange (together with oxygen movenent in opposite direction) and it is actually simple diffusion. Alveoli have huge surface area, thin cell walls and a lot of blood vessels around them. All of these are adaptations that facilitate gas exchange. There is a gradient in partial pressure of the CO2: it is much higher in the pulmonary capillaries than in the alveoili so it moves down its gradient-from the blood to the alveoli (exhale).
Correct answer: C). Coded in either DNA or RNA.
The instructions for making the new copies of the virus are coded either by the RNA or the DNA. The genetic material of the viruses are either the DNA or the RNA and they are known to contain the instructions for making the new viral copies. Before the viral replication, the virus gets into the cell. The viral copies of the virus are known to infect the host.
Hence, the correct answer would be option C.
