SOMEONE PLZ HELP!!!!!!!

Answer:

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution.[1][2] In 1978 Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."

The dark-coloured or melanic form of the peppered moth (var. carbonaria) was not known before 1811. After field collection in 1848 from Manchester, an industrial city in England, the frequency of the variety was found to have increased drastically. By the end of the 19th century it almost completely outnumbered the original light-coloured type (var. typica), with a record of 98% in 1895.[5] The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. It was 14 years after Darwin's death, in 1896, that J.W. Tutt presented it as a case of natural selection.[6] Due to this, the idea widely spread, and more people believed in Darwin's theory.

Bernard Kettlewell was the first to investigate the evolutionary mechanism behind peppered moth adaptation, between 1953 and 1956. He found that a light-coloured body was an effective camouflage in a clean environment, such as in Dorset, while the dark colour was beneficial in a polluted environment like in Birmingham. This selective survival was due to birds which easily caught dark moths on clean trees, and white moths on trees darkened with soot. The story, supported by Kettlewell's experiment, became the canonical example of Darwinian evolution and evidence for natural selection used in standard textbooks.[7]

However, failure to replicate the experiment and criticism of Kettlewell's methods by Theodore David Sargent in the late 1960s led to general skepticism. When Judith Hooper's Of Moths and Men was published in 2002, Kettlewell's story was more sternly attacked, accused of fraud, and became widely disregarded. The criticism became a major argument for creationists. Michael Majerus was the principal defender. His seven-year experiment beginning in 2001, the most elaborate of its kind in population biology, the results of which were published posthumously in 2012, vindicated Kettlewell's work in great detail. This restored peppered moth evolution as "the most direct evidence", and "one of the clearest and most easily understood examples of Darwinian evolution in action".

Answer:

$1.19 per cup

Explanation:

So there are 32 cups in 2 gallons (16 cups per gallon) and we already know how much the whole container costs. So now all we have to do is come up with an equation, such as $38.08/32.

38.08/32 = 1.19

To solve this we must be knowing each and every concept related to gallon. Therefore, $1.19 is the price per cup when a 2-gallon container of laundry detergent costs $38.08.

The gallon presently has one definition inside the imperial system and two in the US customary system (liquid and dry). There have been several definitions and redefinitions throughout history.

Similarly, a Gallon is the standard unit of volume which denoted as “gal”, mainly used to measure the liquid Quantity in the customary systems of the United States and the Imperial System of measurement of the united kingdom.

there are 32 cups in 2 gallons

the price per cup=38.08/32 = $1.19

Therefore, $1.19 is the price per cup when a 2-gallon container of laundry detergent costs $38.08.

Classification-

The process of grouping things

based on similarities.

Taxonomy

The scientific study of how living

things are classified.

Aristotle-Was Credited with creating the first classification system around 5AD. And he only classified objects as plants or animals

Carolus Linnaeus was known as the Father of Taxonomy.And he Gave us the hierarchical system we now use.(His system had 3 Kingdoms)

- Animals

- Plants

- Mineral

**Sorry I don't know the answer to this question here(george fox and Carl worse....)**

The 8 levels of classification:

Broadest levels:

1.Domain

2.Kingdom

3.Phylum

4.Class

Most specific:

5.Order,

6.Family,

7.Genus,

8.Species

*Species is the most specific category of classification of organisms so as each group split into smaller groups the organisms are more specific.**

Domain is The highest rank of organisms in biological taxonomy. It divides all cellular life forms into three groups.

The mRNA code determines which tRNA molecules are used. The purpose of this process is to synthesize protein. DNA contains the information used to make proteins. The presence of uracil (U) in codons makes difference between DNA and RNA. The correct options are A, D, C, C, and C respectively.

Natural chemical substances called nucleic acids are the main information-transporting molecules in organisms.

They are particularly crucial in controlling protein synthesis. Deoxyribonucleic acid (DNA) and ribonucleic acid are the two primary types of nucleic acids (RNA).

That tRNA molecules are utilized is determined by the mRNA code. The creation of protein is the aim of this procedure.

The instructions needed to create proteins are found in DNA. Codons that contain uracil (U) distinguish between DNA and RNA as RNA possesses uracil in plane of thymine in DNA.

In the sequence given in the second image, the sequence of the mRNA will be C – U – A – G – G – A.

Thus, the correct options are A, D, C, C, and C respectively.
