elemental energy is not a modern source of energy . the other three are . pls mark brainliest
The difference in air pressure.
<span>Here are the missing options for the above question:
</span><span>1. The bacterial culture in test tube D was diluted so much that no pink bacteria were left in the sample.
2. The pink bacteria were not able to get enough energy from the nutrient broth in test tube D to live.
3. The white bacteria outcompeted the pink bacteria for the nutrients in the broth in test tube D.
4. The pink bacteria are sediment growers in nutrient broth and the micropipette could not reach them.

It was about Spread Plate Method of Isolation with nutrient broth. Therefore the best answer choice is:
</span><span>1. The bacterial culture in test tube D was diluted so much that no pink bacteria were left in the sample.</span><span>

Dilation of blood vessels will cause them to be nearer to the skin surface. This means that it will be easier for heat to be lost from the blood vessels to the skin and ultimately to the atmosphere via conduction. This loss in heat reduces the temperature of blood and hence the body temperature in general.
If the rate at which blood is pumped is constant (whether blood vessels are constricted or dilated), then blood pressure decreases when blood vessels are dilated because blood pumped at constant speed has more space to pass resulting in decreased blood pressure.
The answers are (Bread mold fungus & Rhizopus stolonifer) hope it helps and have a great day!
