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.
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

Annotate the symbol by the reference image. Then, explain why this symbol represents an ion and how many electrons it has.
• the name of the element
• the charge
• the mass number
• the atomic number
Answer:
since the symbol has a "+1" sign at the top right corner it represents a positively charged ion.
it has 4 electrons as it has "+1" symbol meaning it lost one electron out of initially 5 electrons present.
name of element = Boronthe charge = +1the mass number = 11the atomic number = 5Answer: ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom contained 20 electrons. Since it was neutral, it must also have had 20 protons. Therefore the element is calcium.

Fat cells are expandable. How does this structure relate to a fat cell's function?
A) Fat cells store energy for the body to use later, so being
expandable would help with storage.
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
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.

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

ians do not rely on their lungs alone for breathing in air. They need the skin a
adequate intake of oxygen. Which of the statements below explains the reason
mphibians have only one lung to breathe in air
nly a small amount of air enters the lungs as they breathe.
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
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.

- How do acidic and alkaline environments affect the growth and survival of bacterial?
Answer:
Usually, the catalytic properties of the enzymes are lost and metabolism is halted. Most bacteria grow best around neutral pH values (6.5 - 7.0), but some thrive in very acid conditions and some can even tolerate a pH as low as 1.0. Such acid loving microbes are called acidophiles.

Immune responses can be either innate (nonspecific) or adaptive (specific). Suppose a person comes into contact with bacteria that cause a disease that the person has experienced previously. The production of antibodies to fight off the infection is considered an _____ response, while the development of a fever to inhibit bacterial growth is considered an _____ response. (the possible answers to the blanks are "Adaptive" and "Innate")
Answer:
adaptive; innate
Explanation:
The adaptive immune system refers to a specific type of immunity which is found only in vertebrates. Adaptive immunity is defined by the presence of specialized immune cells (i.e., lymphocytes such as T and B cells). The B cells produce molecules known as antibodies which destroy specific pathogenic microorganisms (e.g., bacteria, viruses) and thus prevent diseases in the future. On the other hand, the innate immune system is the first (and evolutionary more ancient) defense line against pathogenic infections or tissue injury. Innate immunity includes, among others, physical barriers, anatomical barriers, phagocytic enzymes (i.e., lysozymes), phagocytic cells (i.e., macrophages), inflammation, etc. Inflammation is defined as an innate immune response composed of complex biological processes that protect the body by eliminating harmful microorganisms and intracellular danger signals, thereby regulating signaling pathways of many diseases.

3.) people that brush their teeth live longer than those who don't brush their teeth
4.) scientists will find a cure for cancer before the year 2020
I know that 4 isn't the answer so I selected the other three and it said I was wrong. isn't a hypotheses something that can be experimented on so can't all of the three have experiments If I'm making sense
Options 1 and 2 can be tested through experimental procedures.
A hypothesis is an explanation for a given phenomenon from the real world.A testable hypothesis is a plausible explanation that can be proved (or rejected) by an experimental and/or observational procedure. A well-designed experiment should have into account the following characteristics: randomization, replication and local control.Manipulation indicates that one variable (dependent variable) is purposefully changed by the scientist in the environment.The controls must be used to prevent non-controlled factors which might be influencing the outcomes of the experiment.Option 3: it is not possible to carry out an experiment to test this hypothesis.Option 4: it is not a hypothesis and a false anachronic statement (cancer is a multifactorial disease that currently still has not been cured).In conclusion, only Options 1 and 2 can be tested through experimental procedures.
