An object with a mass of 12.59 grams was immersed in water in a graduated cylinder. The volume of the water before was 56.7 mL. After the object was placed in the water, the volume read 63.0 mL. If density = mass/volume, calculate the density of the object to the correct sig figs.
Answer:
[tex]\boxed {\boxed {\sf \rho \approx 2.00 \ g /mL}}[/tex]
Explanation:
The density is the mass per unit volume. It is calculated using the following formula.
[tex]\rho = \frac{m}{v}[/tex]
The mass of the object is 12.59 grams.
The volume was found using water displacement. A known quantity of water was placed in a graduated cylinder (56.7 mL), then the object was added and the water level was recorded again (63.0 mL)The volume of the object is the difference between the initial water volume and the final water volume.
v= final water volume - initial water volume v= 63.0 mL - 56.7 mL v= 6.3 mLNow we know the mass and volume of the object and we can substitute the values into the formula.
[tex]\rho = \frac{12.59 \ g }{6.3 \ mL}[/tex]
Divide.
[tex]\rho = 1.998412698 \ g/mL[/tex]
The original measurements have 4 and 3 significant figures. We always round our answer to the least number of sig figs, which is 3. For the number we found, that is the hundredth place. The 8 in the thousandth place tells us to round the 9 up to a 0 (hundredth place), then the 9 up to a 0 (tenth place), and the 1 up to a 2 (ones place).
[tex]\rho \approx 2.00 \ g/mL[/tex]
The density of the object is approximately 2.00 grams per milliliter.

Why do oxygen levels drop sharply during eutrophication?
Explanation:
during eutrophication, there is a presence of excess algae in the water body. this causes an excess overconsumption of available organic materials by algae, causing the oxygen levels to reduce rapidly.
When the algae population grows rapidly, it may hinder sunlight from reaching other lifeforms and cause dissolved oxygen levels to fall.
What is eutrophication?Eutrophication is the substantial increase in phosphorus, nitrogen, and other organic material in an ageing aquatic environment such as a lake.
As the amount of organic material that can be subdivided into nutrients increases, so does the efficiency or fertility of such an ecosystem.
When the algae population grows rapidly, it may prevent sunshine from reaching other organisms and cause dissolved oxygen levels to fall.
The primary environmental impacts of eutrophication are an increase in suspended particles caused by extensive macroalgal blooms, a decrease in water clarity, and an increase in precipitation rate, which has resulted in the destruction of benthic habitat due to shading of submerged vegetation.
Thus, this way, oxygen levels drop sharply during eutrophication.

How many amino acids must be obtained in the diet because they cannot be made by the body?
Оооо
10
20
Answer:
10
Explanation:
The body is unable to produce essential amino acids. Because the body is unable to produce 9 amino acids, they must be received through diet. Thus, option A is the best choice.
What are Essential amino acids?An obligatory amino acid, also known as an essential amino acid, is one that the body cannot produce quickly enough to meet need and must thus be obtained from the food.
Humans and other animals cannot generate essential amino acids from metabolic intermediates. The body lacks the metabolic processes necessary to produce these amino acids, thus they must be obtained from an external diet.
The body is unable to produce essential amino acids. They must therefore originate from food. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.
Therefore, option A is the best choice.

If everyone on the planet used the same amount of resources as an average American, what percent of the Earth would
need to be used to support everyone?
A. 75%
B. 50%
C. 150%
D. 200%
Answer:
D. 200%
Explanation:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
So we actually would need like 5 Earths.
The option is 200%

Answer:
Natural selection, process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype, or genetic constitution
hope it helped!
Natural selection generally results in a population that is adapted to its current environment. The correct option is B.
What is natural selection?Natural selection is the process through which population numbers of living organisms adapt and change.
Individuals in a population are naturally variable, which means they differ in some ways. This variation indicates that some people have traits that are better suited to their environment than others.
As long as there is some difference between them and that difference is heritable, there will inevitably be a selection of individuals with the most advantageous differences.
Natural selection is a process of evolution in which lifeforms that have beneficial traits procreate more effectively than those lacking the traits, leading to an increase in the frequency of the advantageous things over time.
Thus, the correct option is B.

There is a famous psychology experiment where people sit in classroom in such a way that the person on either side of you can't hear what you say. This works best with more than 20 people.
The first person composes a sentence that has 3 facts in it. He whispers it to the second person who relays it to the third until the last person is told. The point of the experiment is to show that the last person isn't normally able to correctly repeat the 3 facts. In fact, most often what is given is quite mixed up and incorrect.
That's what's wrong with eye witness accounts. You can be certain of what you saw. You can also get it all mixed up.
Describe how urine is formed, beginning with the blood. Make it 5th grade not avanced
Urine is formed in the kidneys of a human being. The urine is passed from kidney to bladder through the ureters. The urine is stored in the bladder. On urination, it is passed from bladder to urethra followed by excretion from the body.
Step by step explanation-
Inside the kidney are present numerous cells called nephrons. Each nephron consists of a small tube called a renal tubule. When urea, ammonia and other waste materials combine, it forms urine and it passes through the nephrons and down the renal tubules of the kidney.

1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.
2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?
An experiment is reliable when its repetition produce always the same result. In science, peer review is fundamental because this process ensures that there is not misleading data that may lead to erroneous results.
In sciences, reliability is a term used to evaluate the quality of research. Reliability refers to the probability that an experiment or result is correct, thereby preventing and mitigating failures over time.
An experiment whose successive repetitions conduct the same result is 100% reliable.
Three examples of reliability in science: the same measurement of the size of the leg of a spider. the observation of the same behavior of birds populations on different days and at different times of the day. the same byproducts from a given chemical reaction when an experiment is repeated two or more times.
Peer review is the most widely accepted process used to validate scientific data. This process (peer review) is fundamental to facilitate the growth of scientific knowledge.
During peer review, independent scientists assess the originality, reliability, and significance of a scientific work before its publication.
