Answer:

B) Some of the product escaped as a vapor from the crucible.

Explanation:

Impurities and magnesium not reacting completely would not lead to less product necessarily. Nitrogen gas getting into the crucible would lead to a larger product mass.

Answer the following questions.
Dafna1 [17]

Answer: reading paper books and magazines,  sleeping in beds under cotton sheets, having a sandwich for lunch , sitting at wooden desks , I picking wildflowers , eating a favorite breakfast cereal.

Explanation: These are all correct because each has to deal with plants. For example, reading the paper books, sleeping in the bed and sitting at the wooden desk all have to due with the products that come from plants. Paper, cotton, and wood are all grown from plants and turned into resources. Next picking flowers, eating foods are also direct examples of how plants help us. Picking flowers that come directly from plants. Then eating food that is grown from plants shows that it is directly plants providing for humans.

Does this mechanism produce a change in individuals or populations? Explain
I am Lyosha [343]
<h2><u>Answer:</u></h2>

<u>mechanism:</u>  the process of evoluton .

Evolution is the process by which veriety of  modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all  0rganisms and the amazing diversity of that organisms  but exactly how does it work? Fundamental of  the  process of evolution  is genetic variation upon which selective forces can act in order for evolution to occur.

Examines the mechanisms of evolution focusing on:

•<u>Decent </u>: the  genetic differences that are heritable and passed on to the next generation successfully.  

• <u>mechanisms of change</u>:   Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .  

• The random nature of genetic drift  and their effects .

• How variation, differential reproduction, and  heredity result in evolution natural selection .

• How different species can affect each other's evolution through co-evolution.

All of these mechanisms can cause changes in the frequencies of genes produce change in  in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.

gtnhenbr [62]

Answer:

habituation

Explanation:

Habituation is a kind of learning process in psychology, which describes the behavioral responsiveness of humans and animals to a stimulus that is presented repeatedly without a change, punishment or reward. It explains that response of humans and animals to a stimulus that is repeatedly presented will reduce over time. The more the repetition, the less response is exhibited.

Hannah is simply exhibiting a lesser degree of responsiveness to the repeated occurrence of same stimuli which is termed habituation.
