Why water alone is not sufficient to remove oil spots? Explain!

Answers

Answer 1

Problematic fat molecules called triglycerides (oil) do not dissolve in water because of their hydrophobic (water-fearing) nature. The water can push around the oil and make more of a mess. Cooking oil is different then motor oil and require different treatment.

Why is the temperature at the extremities, such as the fingers,
sometimes colder than the core body temperature?
O A. So that less energy is lost in cold environments.
OB. The fingers need to be colder to protect the durability of the nails.
C. The fingers do not have thermoregulation mechanisms.
D. So that more energy is lost in cold environments.

Answers

Answer:

A. so that less energy is lost in cold environments.

Explanation:

When it’s cold outside, your body makes sure to keep the blood flowing to your core and vital organs to keep them warm. This can change the amount of blood flow to your hands and feet, making them feel cold. This is normal. The blood vessels in your hands and feet constrict (spasm) when it’s cold, to prevent heat loss from your core

What assumption regarding the population is necessary for making an interval estimate for the population mean?

Answers

Answer:

The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:

a. We assume that the population has a normal distribution.

b. We assume that the central limit theorem applies.

Explanation:

The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:

a. We assume that the population has a normal distribution.

b. We assume that the central limit theorem applies.

A normal distribution describes how the values of a variable are distributed. It is a probability distribution that is symmetrical about the central value or the mean, i.e. 50% of data are found to the left and right of the mean respectively. Most of the data are clustered around the mean, i.e. they occur or are found near the mean than far away from the mean. The graph form of a normal distribution will appear as a bell curve. In a normal distribution, mean = mode = median.

The Central Limit Theorem states that irrespective of the underlying distribution of a sample, when a variable does not follow a normal distribution, repeated random samples from the population will give sample means they are normally distributed. This means that the sampling distribution of the sample means approaches a normal distribution as the sample size gets larger.

Making Inferences Why do
you feel pain when you pull on
your hair or nails, but not when
you cut them?

Answers

Answer:

because the pain in our body is from the skin or tissue so when you pull the hair you are actually up rooting it from its attachment with ur skin hense you feel the pain

So your hair and nails are made of Keratin and don’t have nerves In them but they do have nerves attached to them. So pulling your nail or hair triggers the nerves around them and send signals to your brain to trigger pain. This is kinda similar to a spider web. The spider isn’t connected to the fibers in her web but she does feel the vibrations around her from the web. If you damaged a part of the web she wouldn’t be injured herself but she will be disabled because she essentially is missing a part of the system which she uses to survive. ( fun fact spider vision is actually very poor so their webs act as their eyes)

B) Fat cells burn energy quickly when other food source is available, so being expandable would help with the rapid burn.

C) Fall cells protect organs, so being expandable can help with cushioning.

D) Fat cells do not expand

Answers

Fat cells burn energy quickly when other food source is available, so being expandable would help with the rapid burn.

The relationship between the expandability of fat cells and a fat cell's function is ; ( A )  Fat cells store energy for the body to use later, so being expandable would help with storage.

Fat cells specialized for the storage of energy in human body is the Adipose tissue which can expand between 60 to 70% of the weight of the human body in response to changes in the energy balance of the body.

Adipose tissues store energy in form of triglycerides and in order to store more energy for later use the Adipose would need to be expandable to accommodate the required amount of energy.

Hence we can conclude that the relationship between the expandability of fat cells and a fat cells' function is Fat cells store energy for the body to use later, so being expandable would help with storage.

Answers

About the question:

You will find the chart in the attached files

Answer:

b) x: fin

   y: lateral line

   z: swim bladder  

Explanation:

The dorsal fin is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.

The Lateral Line is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.

The swim bladder is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.

As the most junior member of a lab, you are tasked with generating cell lines that accumulate DNA damage to investigate how random mutations affect transformation of cells into cancer cells. You decide to mutate proteins in the p53 pathway. Which three proteins would you mutate

Answers

Answer:

In p53 pathways, 3 proteins which are mutate and cause cancer that proteins are:

1.BRCA2  

2. p53 in Rb genes binds with deoxyribonucleic acid that stimulates another gene to produce a protein known as p21 that interacts with cdk2. When p21 is combined with cdk2  cell will not pass through to the next stage of cell division. This is Li-Fraumeni syndrome (when p53 causes cancer from parents to offspring)  

3.BRCA1  

The parent that transmits mutation in one of these genes has a 50% chance of inheriting the mutation. The effects of mutations in BRCA2 and BRCA1 are seen when the person's second copy of the gene is normal.

In 1940 Ethel Brown Harvey evolve a technique for separating embryonic sea urchin cells. She took a pair of embryonic cells to develop from the first cell division after Harvey's fertilization. She settles the pair of cells in a hypertonic solution, carrying double the amount of salt as that contained in seawater. Most sea urchins produce a group of early embryonic cells which is known as micromeres. Small blastomeres Harvey that form by unequal cell division at the vegetal pole of the early embryo.

surface area of the lungs are small compared to other terrestrial vertebrat
surface area of the lungs do not have folds compared to other terrestrial v​

Answers

Answer:

These lungs are primitive and are not as evolved as mammalian lungs. Adult amphibians are lacking or have a reduced diaphragm, so breathing through the lungs is forced. The other means of breathing for amphibians is diffusion across the skin. To aid this diffusion, amphibian skin must remain moist.

Two common respiratory organs of invertebrates are trachea and gills. Diffusion lungs, as contrasted with ventilation lungs of vertebrates, are confined to small animals, such as pulmonate snails and scorpions.

Explanation:

Amphibians utilize gills for breathing early in life, and develop primitive lungs in their adult life; additionally, they are able to breathe through their skin.
