D- skin appears blue because of a lack of oxygen in the blood
It was ancient fossils containing ----Ancient bacteria---
Answer:
The following is the formula to determine the size from minor spaces and ocular spaces on the stage micrometer:
Size = Number of minor spaces * 10 micrometer / Number of ocular spaces
A = Number of minor spaces is 2 and the number of ocular space is 1,
Size = 2 * 10 / 1 = 20 micro micrometer. Thus, the size of a bacterium is 20 micrometers.
B = Thus, it can be said that the size of the bacterium is almost 4 times bigger in comparison to a human red blood cell, which is 6 micrometers in diameter.
Answer:
inputs: carbon dioxide, water
outputs: sugar, oxygen
Explanation:
Here is the equation for photosynthesis:
CO2 + H2O ----sunlight energy---> C6H12O6 (glucose/sugar) + O2
When a stimulus is being detected, this stimulus is being sent to the brain through the sensory neuron, going to the spinal cord then to the brain. The brain then interprets these stimuli, and responds to it using the motor neurons. These are the neurons that are responsible in our actions depending on the stimuli we are exposed to. Hope this helps.
