Answer:
B or C
Explanation:
Alchemy rely a lot on the spiritual connections to the four elements and they are fire, water, earth and air while chemistry is a lot more logical, factual and scientific based. Also, chemistry is considered as science, while alchemy is not.
Alchemy was based more on experimentation and had little basis in science. Chemistry utilizes both experimentation and scientific practices. Modern chemistry basically relies on scientific theories and experimental results, but the alchemy was a blend of myths, religion, magic, astrology, philosophy, and spirituality.
Answer:
0.501 L
Explanation:
To solve this problem we will use Boyle,s Law. According to this law "The volume of given amount of gas is inversely proportional to applied pressure at constant temperature".
V∝ 1/P
V= K/P
VP=K
Here the K is proportionality constant.
so,
P1V1 = P2V2
P= pressure
V= volume
Given data:
P1= 1 atm
V1= 461 mL
P2= 0.92 atm
V2= ? (L)
To solve this problem we have to convert the mL into L first.
1 L = 1000 mL
461/1000= 0.461 L
Now we will put the values in the equation,
P1V1 = P2V2
V2= P1V1/ P2
V2= 1 atm × 0.461 L / 0.92 atm
V2= 0.501 L

Purebreds
Purebreds are the result of true breeding where specimens breed true-to type when mated like-to-like. The idea is that the purebred has fundamental characteristics that are consistent, replicable and predictable. Pure breeding is of necessity carried out from a restricted gene pool which has been a cause for concern. As the positive characteristics of any species or type are perpetuated through true breeding so are the undesirable traits which are a result of inbreeding. The limited gene pool leaves purebred products susceptible to a range of congenital health issues particularly where the emphasis is on aesthetics.
Hybrids
A hybrid organism is one with parentage of two different species. In the animal kingdom, mules (horse and donkey), ligers (tiger and lion), yakalos (yak and buffalo) and so on are familiar hybrids. There are various types of hybrids possible. The most obvious kind is offspring resulting from the interbreeding of two species. The second kind is hybrids between different subspecies which include intra-specific (between subspecies), intergeneric (between genera) and interfamilial hybrids. The third sort of hybrid is that caused by selective breeding to enhance and make consistent desirable characteristics such as heat tolerance amongst certain breeds of cattle.
