Biology Questions

The given statement that all cells divide at the same rate is FALSE.

No, all cells do not divide at the same rate. Cells that require frequent replenishing, such as skin or intestinal cells, may only take roughly twelve hours to complete a cell cycle. Other cells, such as liver cells, remain in a resting state (interphase) for up to a year before undergoing division.

Air or gas can build up in the pleural space and when this happens, it's called a pneumothorax.

Hence the given statement is TRUE.

Oxygen in our blood is transported by a protein named Haemoglobin.

The ATP is synthesized from ADP and an inorganic phosphate and involves special channel proteins that are embedded in a membrane. ATP is formed in the electron transport chain of photosynthesis and cellular respiration.

Photosynthesis only occurs in autotrophic organisms while respiration occurs in all types of organisms.

A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function.

Hence, Cells with similar markers stick together and function as tissues.

Blood alcohol concentration is affected by factors such as body size and gender. Women are usually smaller than men, and that they turn out less of the enzyme that breaks down alcohol.

For those reasons, most girls can have a higher BAC than the typical male if they each drink an identical quantity of alcohol.
