Hi!
During a chemical reaction, some of the basic signs that a chemical reaction is occurring is a color change and heat / light also burning . You can clearly see these changes happening

But changes in volume is a physical property, not a chemical.

I hope this helps!

Africa and South America are 4,000 km apart. If the plates move away from each other at a rate of 30 km per 1 million years, how
yulyashka [42]

Answer:

The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.



The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year. That is about the same rate at which your fingernails will grow.



The distance from New York to London is in 3459 miles (5567 km). What will the distance be in 5 million years?.





The distance from New York to London in 5 million years will be 3552 miles (5717 km). So if today it takes us 7 hours and 30 minutes to fly to London at a speed of 460 miles per hour, in 5 million years at the same rate of speed will take us close to 8 hours.

Why does putting your name on a health behavior contract indicate your commitment to the contract?
dimulka [17.4K]
Because it is written. A popular tool used for motivation and commitment is the use of written contracts and often does not even need to be as lengthy as a contract. A slip of paper or even another writing surface has been shown to significantly increase the likelihood of committing to that action. 

There is also premeditation involved when signing a contract or writing on a piece of paper. An individual has read and recognized the written words and then signed it according to a commitment to that act. As such there is a significant amount of thought put into the over procedure, and thus increases again the likelihood of an individual to be committed to completing those actions.

Aside from all the factors of motivation, the signing demonstrates commitment to the contract because that is fairly universally understood to be the way in which people recognize and formally commit to contracts. Whatever the context of the action, whether signing papers to buy a house or for a new job, the signing of the contract is the commitment of the individuals involved to complete the requirements within the contract. Although in this instance the healthier behavior most directly affects the individual who signs the paper.

Anuta_ua [19.1K]

Answer:

0.7

Explanation:

Using Hardy-Weinberg equation of genetic variation being constant when disturbing factors such has mutation and others are removed.

p² + pq + q² = 1 and p + q = 1

where p² is the frequency of the homozygous dominant genotype (RR) and q² is the frequency of the homozygous recessive genotype (rr) and 2pq is the frequency of heterozygous genotype (Rr). p represent the frequency of "R" and q represent "g". since the coefficient against the green/green homozygote is 0.30 then

the fitness of the green/green homozygote = 1 - 0.3 = 0.7
