When a haploid egg cell comes in contact with a haploid sperm cell they will fertilize and instantly began the cell cycle/mitosis.
A haploid egg cell, if not fertilized, will die after about 24 hours.
Answer:
A. One cell took over another cell
Explanation:
Mitochondria is an organelle present in a eukaryotic cell that performs the function of producing ATP molecules from the available substrates in the cell.
The mitochondria organelle has its DNA other than the cellular DNA which shows that it was once an independent organism. This was proved by the endosymbiotic theory that during the formation of the eukaryote cell, the proto-eukaryote engulfed the chemosynthetic bacteria which later formed the symbiotic relationship with the cell and evolved into the mitochondria.
Thus, Option-A is the correct answer.
The answer is all Earth's organisms and the non-living environment with which they interact.
Answer:
Keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation.
The intensity of a stimulus, such as the intensity of noise that a person experiences, can be communicated through the number of neurons that fire action.
A stimulus is a change detected by the neurons in a body for which a response is produced. The sensory nerves sense a stimulus and send signals to the brain. The brain interprets this message and sends a response action signal through the motor neurons.
The intensity of a stimulus is detected by the impulse of action potential carried by the sensory neurons. The number of sensory neurons will increase if an intense stimulus, which will lead to the generation of an increased action potential. The brain will determine the intensity of the increased action potential and send a response action from the motor neurons to act accordingly.
