Why does a chemical change change the chemical makeup of matter

Chemical change is a process where a current substance changes or is made into a new type of substance. Unlike the physical change, which is reversible. Chemical change stays into a its new form. Take for instance these -physical change- examples, making ice cubes. The process involves solidification or freezing where the water becomes ice or solid but when it melts back to its original or typical form with respect to temperature, it’s still water. When the paper is cut into pieces it isn’t burned or exposed to a stimuli that can trigger immediate change in its composition. It’s still the same. On the contrary, baking a cake involves these different compositions or substances –flour, egg, yeast and etc. that is baked to a cake, a newly formed unified substance of all the included ingredients.

The scientist that did NOT contribute to the idea of natural selection is none of the above. The answer is letter D. Both Charles Darwin and Alfred Russel Wallace contribute to the natural selection and are biologist. Darwin hypothesized his theory of evolution while Wallace supplied Darwin with birds for study only to found out that both have the same hypothesis regarding natural selection.

What is a communicable disease chain? what steps can a nurse can take to break a link within the communicable disease chain?

Kaylis [27]

A diseases may be classified as either communicable or non-communicable. Communicable diseases are caused by pathogens who inhabit a host, man (I'm not saying man is the only host or man is necessarily the final host; there could be many host) who in turn passes the disease to another. Pathogens are viral, bacterial, parasitic and fungal. There are several stages before the pathogen metamorphoses into a full-blown disease. The stages in which several events happen builds up before the pathogen affects the final host is called a communicable disease chain. There are six stages ( Pathogen, reservoir, portal of ext, mode of transmission, portal of entry and susceptible host) in the communicable disease chain but the step a nurse shouod take is 1. Destroy the second link (Reservoir) by thoroughly sanitizing the environment. Obviously, this is where the Pathogens live. If the reservoir is taken care of; there's no way they could infect the host.

Clear cutting has a similar effect as controlled burning of a forest. True False

zysi [14]

The correct answer is false and here is why:

Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.

Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.

Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
