Answer:
Time taken to cover the distance 100 m = 2000 year
Explanation:
Given data:
Speed of plate = 5 cm per year
Time taken to cover the distance 100 m = ?
Solution:
Formula:
t = d/s
t = time
d = distance
s = speed
We will convert the given distance into cm.
100 m × 100 cm/1 m = 10000 cm
Now we will put the values in formula,
t = 10000 cm/ 5 cm/year
t = 2000 year
The answer is natural killer cells.
Natural killer cells are a type of lymphocytes and they are important for the innate immune system. They recognise stressed cells much faster than other immune cells. Their response is rapid and usually only a few days after a viral infection. They also respond to <span>cancer cell </span>formation. While other immune cells can detect only those harmful cells that have specific markers on the surface of the cell membrane, natural killer cells can even detect those cells that miss markers for apoptosis.
Explanation:
The answer is D. Krebs cycle. the Krebs cycle only occurs when oxygen is present, and so it would seem to be the same for the electron transport system... although, in anaerobic bacteria, it is still used as a respiratory electron transport chain called physolmere.
Explanation:
This shows movement of a plant. Plant movement due to external stimuli are of two types: tropism and nasties. When the direction of external stimulus decides the direction of response in the form of growth it is called tropism. Thus, tropism is the directional growth movement of a plant part.
