A common way that humans pollute water is through the addition of nutrients (fertilizers and sewage) to water as nonpoint source pollution. These added materials are full of nitrogen and phosphorus, two nutrients that encourage the growth of aquatic producers, such as algae.
Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
Which simple machine can be described as a rope that is threaded through a wheel or disk?
The correct answer is B - Pulley
A pulley is a simple machine that is used to lift loads. It consists of a wheel on which a rope is placed and the rope is pulled by the person towards himself to lift the load that is tied on the other side of the rope. There are three main types of pulleys: fixed, movable, and compound.
Answer:
apply direct pressure to the injury site while manually stabilizing the stick in her arm
Explanation:
Spinal immobilization can generally be explained as the use of adjuncts such as cervical collar, that are being applied to minimize movement of the spinal column.
In this case, since the area where the girl is injured is the forearm, it has no direct connection with the spinal column, this means that, the cervical spinal immobilization is unnecessary.
Therefore, there should be direct application of pressure to the injury site while manually stabilizing the stick in her arm.
