1. Hutton and Lyell were the people that influenced Darwin's idea that life could change slowly over a period of time. Both James Hutton and Charles Lyell were geologists who argued that Earth’s surface was shaped by gradual geological processes and that Earth must be far older than most people believed.
2. Malthus was the person who influenced Darwin's idea that some offspring are better suited for survival than others. Malthus was an economist who argued that human populations grow faster than the resources they depend on. He explained that population growth would always overpower food supply growth, creating states of hunger, disease, and struggle. That stimulated Darwin who than considered that some of the competitors would be better equipped to survive and that those who were less able would die out, leaving only those with the more desirable traits.
3. "Traits acquired during an organisms lifetime can be passed down to its offspring" is the parts of Lamarck's theory of evolution that is no longer supported. Lamarck was the first scientist that proposed that species change over time, but his idea of the inheritance of acquired characteristics is now considered as incorrect (yet, because of the knowledge of epigenetics today, some of his ideas might be partly true).
4. Darwin concluded that humans can influence an offsprings trait, and this is how livestock breeders and farmers influence Darwin's idea. The process of human influence is called artificial selection and it is a process in which organisms evolve traits useful to humans because people select which individuals are allowed to reproduce and pass on their genes to successive generations.

Before a captive breeding program and subsequent reintroduction of the black-footed ferret it is believed that their total popul
irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%

BLUEFIN TUNA: replace with pole or troll-caught Yellowfin tuna, Albacore tuna, Wahoo
Bluefin is the king of the sea. It is the fattiest, richest fish in the sea. Bluefin’s unique flavor contributes to its great appeal. However, we have eaten our way through this species’ ranks and have forfeited our ability to consume this fish. It is a taste that may be lost for many generations to come, maybe forever. However, in most preparations Bluefin can be substituted by pole or troll-caught Yellowfin tuna which, although not quite as elegant, is a great eating experience. For preparations such as grilled tuna, try to seek out pole or troll-caught Albacore or even the tuna cousin Wahoo.

ATLANTIC FARMED SALMON: replace with Wild Alaska Salmon
Substituting for farmed Atlantic Salmon is easy: look for the great quality salmon options from Alaska. All five species of Salmon from Alaska are great stand-ins for farmed salmon. Experiment with the different species to find the one that you like the best. King Salmon is the richest, Sockeye the gamiest, Coho the most balanced, Pink the lightest, and Chum is the most similar to farmed Atlantic Salmon in flavor.

IMPORTED SHRIMP: replace with Oregon Pink shrimp, Alaska shrimp species, or some U.S. farmed shrimp
There are some FANTASTIC shrimp out there that nearly no one knows about. Oregon Pink Shrimp are a delicious product that is very inexpensive and very convenient. Available all year round as a frozen product, these work well in soups, salads, cocktails, sandwiches, nearly every preparation you can imagine. They are smaller than the warm water shrimp but are clean and sweet in flavor and a real treat. Alaska coonstripe, northern and sidestripe shrimp, and spot prawns are all rated “green”. Coonstripe shrimp and spot praws are caught with pots/traps, unlike most shrimp which are caught with destructive bottom trawls. There are some farm raised shrimp options available from U.S. producers which are great eating. They are only a little more expensive and you can eat well knowing that you are supporting not only eco-friendly practices but also helping to create jobs for American
Are the substitutes or alternative products more or less expensive
