When a can is crushed is it going threw physical change or chemical change

Answer:

Ptolemy

Explanation:

Ptolemy is the earliest earliest astronomer and mathematician in the list who lived and worked in the second century AD. Nothing is known about his personal life but his scientific work is well known.

He made his observations using naked eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center.''(Khan Academy). His argument was that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.

Although Ptolemy made significant contributions in Astronomy but he was wrong in positing that the earth did not move at all. This is inconsistent with our present day knowledge about the celestial bodies. Also, his work missed out other planets that were yet to be discovered then such as Uranus, Neptune, Pluto etc.

Food.

Explanation:

Animals get energy from food.

When the temperature and dew point are close together, within 5 degrees Fahrenheit or Celsius, it indicates that the relative humidity is high.

When the temperature and dew point in the atmosphere are in close proximity, it frequently means that fog, mist, or low clouds are likely to form. The reason for this is that the air at the surface is almost saturated, and if it cools down any further or is given more moisture, it will condense into visible moisture at its dew point.

Additionally, since the body's natural cooling mechanisms (sweating) are less effective when the temperature and dew point are close together, it can make the air feel humid and uncomfortable. This could also make people more susceptible to heat-related disorders, especially in hot and humid climates.

A. Different types of tissues work together to carry out a function.

An organ is a structure composed of different types of tissues that work together to perform a specific function in an organism. Organs are more complex than cells and tissues, but they are not the most complex level of organization in life. The most complex level of organization would typically refer to systems or organisms as a whole.

A possible consequence of a single nucleotide addition to the DNA code used to generate a protein is a frameshift mutation, which can alter the entire coding sequence and protein structure

.An addition or deletion of a single nucleotide can cause the DNA code to shift one base over, causing an entirely different set of codons to be read. This creates a frameshift mutation, which changes the entire coding sequence downstream of the mutation point. Because codons are read in groups of three, an insertion or deletion will alter the remaining codons after the point of mutation.A protein sequence that is produced from the mutated DNA code is likely to be altered significantly because the codons following the point of mutation will not be read in the correct manner. This can result in a stop codon being generated prematurely or a frameshift mutation, which can alter the entire coding sequence and protein structure.In conclusion, a possible consequence of a single nucleotide addition to the DNA code used to generate a protein is a frameshift mutation, which can alter the entire coding sequence and protein structure.

The following may be caused by mobile genetic elements except "none of the above." Mobile genetic elements can disrupt a gene, activate a gene in which they reside, cause chromosome breaks, and undergo mutation.

It's true that mobile genetic components can prevent a gene from encoding a functional protein.

False: you cannot change how a gene expresses itself.

By introducing new promoters, splice sites, or other post-transcriptional changes, mobile genetic elements (transposable elements) can change the way that genes are regulated. When mobile genetic elements enter introns, they may develop into exons or be spliced into the gene's mRNA, which may result in the introduction of stop codons.

Enzymes in a reaction act as catalysts.  They speed up the chemical reaction process.

Answer:

Explanation:

(a) The best way to describe this study is: Experiment with 2 treatments: the bandages with antibiotic and the bandages with antibiotic applied first.

(b) To calculate the critical value for a 99% confidence interval for the difference in population means, we need to find the t-value. Since the sample size is relatively large (n = 50), we can use the normal distribution approximation. The critical value for a 99% confidence level corresponds to the z-value at the 0.995 percentile. Using a standard normal distribution table or technology, the critical value is approximately 2.576 (rounded to three decimal places).

(c) To calculate the 99% confidence interval for the difference in true mean healing time between the two types of bandages, we can use the formula:

Confidence Interval = (mean1 - mean2) ± (critical value * standard error)

where:

mean1 = mean healing time for Group 1 (bandages with preloaded antibiotic)

mean2 = mean healing time for Group 2 (bandages with antibiotic applied first)

critical value = 2.576 (from part b)

standard error = sqrt[(variance1/n1) + (variance2/n2)]

Substituting the given values into the formula:

mean1 = 1.60

mean2 = 3.28

standard deviation1 = 0.51

standard deviation2 = 0.76

n1 = n2 = 50

standard error = sqrt[(0.51^2/50) + (0.76^2/50)]

≈ sqrt[0.002601 + 0.009216]

≈ sqrt(0.011817)

≈ 0.1086 (rounded to four decimal places)

Confidence Interval = (1.60 - 3.28) ± (2.576 * 0.1086)

= -1.68 ± 0.2798

= (-1.96, -1.40) (rounded to two decimal places)

Therefore, we can be 99% confident that the difference in true mean healing time in wounds for the bandages with preloaded antibiotic and the bandages with antibiotic applied to the wound first is between -1.96 and -1.40 days.

(d) The statement is true. If the confidence interval includes zero, it means that zero is within the range of plausible values for the difference in mean healing times. This suggests that there is insufficient evidence to conclude that there is a significant difference between the mean healing times for the two different bandages.

Yes, cellular respiration results in a net input of energy.

Cellular respiration is a process in which living cells produce energy from nutrients by breaking them down in the presence of oxygen. The process of cellular respiration results in the net input of energy because it generates more ATP (adenosine triphosphate) than it consumes. ATP is the energy currency of the cell that drives all cellular activities.
The energy-releasing steps of cellular respiration occur in three stages: glycolysis, Krebs cycle, and oxidative phosphorylation. Glycolysis takes place in the cytoplasm and results in the net production of two ATP molecules per glucose molecule. The Krebs cycle occurs in the mitochondria and generates two ATP molecules per glucose molecule. The oxidative phosphorylation, also known as electron transport chain, takes place in the inner mitochondrial membrane and results in the production of about 32-34 ATP molecules per glucose molecule.

In conclusion, cellular respiration is an energy-releasing process that produces more ATP than it consumes, resulting in a net input of energy. This energy is crucial for the cell to carry out various functions like muscle contraction, cell division, and nerve transmission, among others.

One theme that can be related to the properties of water is organization. The ability of water to function as a versatile solvent arises from the organization of water molecules.  Water is an incredibly unique substance that has many properties that make it essential for life. One of these properties is its ability to dissolve a wide range of substances, earning it the title of a universal solvent. This ability arises from the organization of water molecules.

The water molecule is polar, meaning it has a positive and negative end. The oxygen atom has a slightly negative charge, while the hydrogen atoms have a slightly positive charge. This polarity allows water molecules to form hydrogen bonds with other polar or charged molecules, such as salts, sugars, and amino acids. The hydrogen bonds cause the polar molecules to be attracted to water molecules, which leads to the molecules dissolving in water.

In conclusion, the organization of water molecules enables water to be a versatile solvent and dissolve a wide range of substances. This property is crucial for life as it allows for essential molecules to be transported within organisms and chemical reactions to occur.
