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.

which of the following hypotheses can be tested with experiments? select all that apply
1.) a diet low in sugar reduces the risk for heart disease
2.) coffee increases subject performance on intelligence tests
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.

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.

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.

21. What determines the kind of genes an organism
possesses?
Answer:
The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA.
Answer:
The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA. ... The order of bases as you go down the rungs of the ladder determine what genes an organism will have, and therefore, what traits it will have.
Explanation:
Fun facts:
Genes carry the information that determines your traits which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes. ... And chromosomes are found inside cells. Your body is made of billions of cells.
Some experts attribute the increase in ADHD diagnoses to an increased awareness of the disorder, while others attribute the increase to ______ diagnoses.
Answer:
incorrect
Explanation:
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. ADHD is characterized by different behaviors that include one or more of the following symptoms: inattention (poor concentration), impulsivity (interrupting behavior) and hyperactivity (state abnormally active). It has been reported that DHD diagnoses in children between 4 and 17 years of age dramatically increased from 6 percent (6%) during the period 1997-1998 to 10 percent (10%) during the period 2015-2016. Although the causes of this increase have not been established, the American Psychiatric Association (APA) indicates that the increase might be due to the increased access of communities historically relegated to receive care and decreased stigma to be diagnosed with ADHD. Other possible causes range from chemical factors to unhealthy habits during pregnancy (e.g., smoking, substance abuse, poor nutrition). On the other hand, it has also been proposed that this increase may be as a result that ADHD is often misdiagnosed and confused with other conditions (e.g., bipolar disorder, autism, kids being kids, etc).

La polidactilia en la especie humana se debe a un alelo dominante. Entre Francisco y Martha, ambos abuelos de Santiago, uno de ellos tenía polidactilia, sin embargo Juan su hijo (papá de Santiago) nació normal. A pesar de ello Santiago es polidactílico. La explicación a esta situación es que
Respuestas:
A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.
B) Como uno de los abuelos era aa (homocigoto recesivo-normal) y el otro Aa (heterocigoto-polidactílico), Juan nació probablemente aa (homocigoto recesivo-normal) y por ello no hay manera que Santiago naciera polidactílico.
C) Como uno de los abuelos era aa (homocigoto recesivo-normal), Juan nació probablemente aa (homocigoto recesivo- normal) y por ello Santiago es polidactílico.
D) Como Francisco y Martha eran Aa (ambos heterocigotos-polidactílicos), Juan nació probablemente AA (homocigoto dominante- polidactílico) y por ello Santiago es polidactílico.
Answer:
A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.
Explanation:
La polidactilia es una malformación causada por un alelo dominante asociada con al aparición de más de 5 dedos en cada pie o más de 5 dedos cada mano. Un alelo dominante es una variante génica capaz de enmascarar la expresión de un alelo recesivo en individuos heterocigotos, es decir, en individuos portadores de una copia del alelo dominante y una copia del alelo recesivo para un gen en particular. De este modo, un alelo dominante es por definición aquel que será expresado en el fenotipo, con lo cual el único modo en el cual Santiago sea portador del alelo dominante causante del rasgo "polidactilia" es que él lo haya heredado, ya sea del padre o de la madre (es importante aclarar que también el alelo dominante puede haber surgido por mutación en la línea germinal). En este caso sabemos de acuerdo al enunciado que el padre de Santiago no tiene polidactilia y por lo tanto no es portador del alelo dominante, con lo cual se espera que Santiago haya heredado esta condición de su madre.
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
- 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.
