Answer:
The correct answer is - people accept it in exchange for goods and services.
Explanation:
Money is valuable because we know that it is "accepted." Money can be used to purchase goods and services even though it is no longer backed by gold. Security measures prevent counterfeiting but do not add value.
People know at that time that their current money has value when they accept it in exchange for goods or services, which is option C, as money is a medium of exchange.
The value of money is influenced by central banks. Different countries have different currencies, but the currency that is stable and has more security has more use. Money is also linked to the underlying economics, such as the ability of a country to buy and manufacture goods, thus increasing the economy. There are also many security measures, such as unique designs, special inks, holograms, etc., that are helpful for maintaining trust and confidence in the currency.

Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.

Sally is a 41 year old female with a history of unsuccessful weight loss attempts. In the past, Sally has tried "almost every diet known to man" and now wants to lose "at least fifty pounds" and "stop fighting with myself". Sally lives alone, and works as an accountant. Her hobbies include reading, spending time with her cat, and shopping. She describes her life as "pretty isolated" and rates her happiness at a 4 out of 10. She explains that when trying to change her behavior, she usually "falls off the bandwagon after a few days", and describes herself as "stuck". She has no history of injuries or preclusions to exercise and has recently had a clean physical exam, with the exception of needing to lose weight.
Describe what approach you would take with Sally to help her change her behavior?
Answer:
the approach has been described below
Explanation:
I will have to use motivation as a way of enhancing change in the life of Sally. From this question, she seems to be a lonely lady, with low self-esteem and no physical activity. The first thing I would do is to help to get her out of monotony by motivating her.
Once motivated, I would help plan her diet and add combinations of physical activities. These activities may include walking and running. With time an expert would take over her physical training.
She has to make time for other activities such as yoga or community work. The purpose for this is so she can meet and connect with other people, this would give her a sense of belonging. And would help boost her self image.
In conclusion, Sally needs a combination of physical and emotional therapy in order to change her lifestyle.
w, use what you have learned about heredity to complete the chart below. The allele pairs in the left column represent eye color in fruit flies. Ris the
ominant color (red), and r is the recessive color (white). Study the chart and fill in the missing phenotypes.
Answer:
RR is hom0zygous dominant and will Red
Rr is heterosygous and will also be red
rr is hom0zygous recessive and will be white
Explanation:
The filling of the chart with respect to the genotype given is as follows:
RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies. What is meant by Genotype?Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.
As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.
In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.
Therefore, the filling of the chart with respect to the genotype given is well described above.

Diabetes is a disease characterized by the inability to break down sugars. Often a person with diabetes has a defective DNA sequence that messes up the code for making insulin. Suppose a person has a mutation in their DNA, and the first triplet for the gene encoding insulin is CCC (instead of CCA). Determine what amino acid the new DNA triplet codes
Answer:
The new CCC codon codes for proline, while the original CCA codon also encodes for proline
Explanation:
A synonymous substitution is a mutation produced by the substitution of one nucleotide for another in an exonic gene segment which doesn't modify the original amino acid in the protein sequence. Moreover, a silent mutation is any alteration in the nucleotide sequence that does not produce an observable effect on the organism's phenotype. The example above describes a synonymous substitution because the new codon (CCC) also codes for the same proline amino acid as the original non-mutated codon, thereby the resulting protein sequence remains unchanged. Consequently, in this case, mutations associated with diabetes are located at other gene regions. The genetic code is degenerate because different codons can code for the same amino acid.

DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.
DNA contains genetic information that is passed from adult organisms to their offspring during reproduction.Each offspring forms by the combination of the parent's gene or DNAThe actual sequence of DNA on each of the chromosomes is unique due in part to recombination.recombination causes genetic variation and made everyone unique.This is incorporated in the nucleotide sequences in DNA molecules.Thus, DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA

the developing of a fetus happens in the uterus
The female reproductive system includes the glands and organs that produce the female gamete, the egg. The highlighted part in the diagram stores eggs. Thus, option C is correct.
What are the parts of the female reproductive system?The female reproductive system has various organs like ovaries, fallopian tubes, vagina, uterus, accessory, and other external organs. They are involved in the production and storage of eggs or the ovum.
The ovaries are the main organs that are two in number and oval-shaped structures, located on either side of the uterus, and produce ovum and hormones, estrogen and progesterone.
During the menstrual cycle, one of the ovaries releases the ovum in the fallopian tubes that may get fertilized or get shaded with the blood and tissues. The egg is produced through the process of oogenesis in the ovaries.
Therefore, the highlighted part is the ovary that stores the egg.

If yes than plz ❤️
After chemical weathering, the rock changes form. Therefore, option C is correct.
What are weathering and its types?The breakdown or dissolution of rocks and minerals on the surface of the Earth is known as weathering. Once a rock has been disintegrated, the minerals and rock fragments are carried away by a process known as erosion. Weathering and erosion can be caused by water, acids, salt, plants, animals, and temperature changes.
Because it contributes to the formation of numerous different types of landforms on the surface of the earth, weathering is a crucial activity. For instance, weathering is the process that gives rise to mountains, canyons, and caves.
There are three types of weathering and that is physical, chemical, and biological weathering. After chemical weathering, the rock changes form. Therefore, option C is correct.
