Answer:
reduced or poor blood supply
Explanation:
Since errors in the repair of DNA breaks can generate instability in the genome, repair of these breaks is a highly regulated process.
It is, therefore, essential the existence of control mechanisms that detect errors in this process and stop the cell cycle to allow the cell to repair the breaks, and if this is not possible, to eliminate the damaged cell.

Which of the following is NOT a statement from the cell theory?
O All cells come from pre-existing cells.
•All cells require water for survival.
•All living things are composed of cells.
•Cells are the basic unit of structure and function of living things.
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
All cells require water for survival is not a statement from the cell theory.
What is cell theory?The cell theory is a fundamental principle in biology that states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. The theory was first proposed by German scientists Matthias Schleiden and Theodor Schwann in 1839, and later refined by Rudolf Virchow in 1855. The three main principles of the cell theory are:
All living organisms are composed of one or more cells.The cell is the basic unit of life and structure for all living organisms.All cells come from pre-existing cells through the process of cell division.The cell theory is considered one of the most important and enduring concepts in biology, and it forms the foundation for understanding the structure and function of cells and the organization of life on Earth.

If the frequency of the black allele for the moth coloration gene in newly founded island population of moths in genetic draft lab simulation was 78% what was the frequency of the white allele in that same population at the same time?
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".

Explanation:
Hope this helps
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.
What is nucleic acid?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.

A 2-gallon container of laundry detergent costs $38.08. What is the price per cup?
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.
What is gallon?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.
