Observe a vertical section of human skin through a tattoo, using low-power magnification. Note the location of the dispersed ink granules within the upper portion of the dermis. From a thin vertical section of a tattoo, it is not possible to determine the figure or word of the entire tattoo as seen on the surface of the skin. Compare this to the location of melanin granules found in dark (heavily pigmented) skin. Suggest reasons why a tattoo is permanent and a suntan is not.
Answers
Answer:
A tattoo is permanent because the pigments are applied into the dermis, while suntan is not permanent because it affects only the epidermis, which undergoes constant renewal
Explanation:
The epidermis is composed of cells located in the upper layers of the skin. The superficial epidermal layer is constantly being renewed by new cells by the processes of mitosis and keratinization, i.e., by cell division and accumulation of keratine in the cytoplasm of epidermal cells during their terminal differentiation. In consequence, a tan is not permanent because surface epidermal cells naturally exfoliate over time. Moreover, tattoos are permanent because tattoo pigments are injected into the dermis layer and dermal cells are not replaced. The dermis is a layer of the skin located between the epidermis and subcutaneous tissue.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
Answers
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.

1. Who determines the gender of your baby .... the mother or the father, or both? _____ Explain:
Answers
Answer:
The one who determines the gender of a new baby is the father, since he is the carrier of the X and Y sex chromosomes.
Explanation:
The sex chromosomes X and Y are called sex determinants, since the sex of the offspring depends on them:
XX corresponds to the female sex. XY corresponds to the male sex.A mother can only provide her offspring with X chromosomes, while the father can provide both X and Y chromosomes, so he is the one who determines the sex of a new child. In this case, the possibility of having a male or female child will always be 50:50

Which statements describe mass or weight measured in newtons
Measured in kilograms

Changes when gravity changes
The amount of matter in something
A gravitational pull
Answers
The statement that best describe mass and weight is that there are both measured in kilograms.
What is mass of an object?Mass is a scalar quantity that measures the amount of matter in an object. It is a fundamental property of an object and is determined by the number of particles and their arrangement in the object.
Mass is often used interchangeably with weight, but they are different concepts. Weight is the force that an object experiences due to gravity, and is proportional to its mass and the local acceleration due to gravity. Mass is a constant, whereas weight can vary depending on the strength of the gravitational field.

Answers
For the word problem, If the difference of a number and the fraction \(\frac{4}{3}\) is \(\frac{11}{3}\), then the number is 5.
How do we solve for the number?The above mathematical problem is a word problem. Word problems are problems that are written in words, rather than in symbols.
To solve for the difference or mystery number, we say, Let x be the number.
The problem states that x - \(\frac{4}{3}\) = \(\frac{11}{3}\),
movin - \(\frac{4}{3}\) to the other side of the equation,
we get x = \(\frac{11}{3}\) + \(\frac{4}{3}\) = \(\frac{15}{3}\)
We solve the fraction by dividing 15 by 3
\(\frac{15}{3}\) = 5

O Active Transport in Cells -Causes molecules to move until they are evenly distributed -Moves from high concentration to low concentration -Has no need for added energy -Can occur with or without a membrane being present O Passive Transport in Cells O Osmosis O Diffusion
Answers
Answer:
passive transport
Explanation
he simplest forms of transport across a membrane are passive. Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.
Passive transport can take one of three different forms, simple diffusion, which involves the movement of small or lipophilic molecules (like O₂, CO₂, hence option A is correct.
What is transport in Cells?Osmosis involves the movement of water molecules and Facilitated diffusion, the three basic types of passive transport are osmosis, assisted diffusion, and diffusion.
Material flows across the plasma membrane with the help of transmembrane proteins along a concentration gradient (from high to low concentration) in assisted transport, also known as facilitated diffusion, without using up any cellular energy.
Therefore, small molecules or ions can traverse the cell membrane passively without the cell providing any energy, hence option A is correct.
