You can tell if matter is conserved if the substance changes . If the substance changes then matter has been conserved .
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
Answer:
(a) Allow movement in only one plane/direction (that is extension or flexion)
(b) The skeletal system also produces blood cells in their bone marrow
Answer:
Hypochlorhydria is a condition in which the quantity of stomach acids is reduced. When severe forms of hypochlorhydria arise, then it leads to a condition termed as Achlorhydria. The stomach stops producing hydrochloric acid at all in such a condition.
The effects of Achlorhydria would be devastating on the body. It will
- weaken or entirely stop the digestive process.
- impair the gastrointestinal system.
- stop the proper digestion of proteins.
- cause gastrointestinal infections to occur which would entirely damage the digestive system.
- lead to iron deficiency
Hi!
One of the ways we make sure data is reliable is by repeating and replicating experiments.
If we consistently get the same results, then this means that the data is both credible and reliable.
Hopefully, this helps! =)
