Calcium nitrate is a compound commonly used as a plant fertilizer in agriculture and also in
wastewater treatment facilities. Let's suppose you need to prepare a 0.2 molar (0.2 M)
solution of calcium nitrate to spray a crop field. You will need to prepare 500 Liters to have
enough of this solution to spray the entire field. How much calcium nitrate will you need?
Answer:
16400g
Explanation:
The amount of Calcium nitrate {Ca(NO3)2} that will be needed can be calculated as follows:
Molarity (M) = number of moles (n) ÷ volume (L)
According to this question, molarity = 0.2M, volume = 500L
number of moles = molarity × volume
number of moles (n) = 0.2 × 500
n = 100moles
Using mole = mass/molar mass
Molar mass of Ca(NO3)2 = 40 + {14 + 16(3)}2
= 40 + (14 + 48)2
= 40 + 62(2)
= 40 + 124
= 164g/mol
Mass = mole × molar mass
mass = 100 × 164
mass = 16400g of Ca(NO3)2

#carryONlearning5. Which describes the variable that is changed to test the prediction?
experimental
control
dependent
independent
Answer:
Independent
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Hence, independent variable describes the variable that is changed to test the prediction.
Which of the following blood vessels would have the highest blood pressure?
A dilated vessel with high blood volume
A constricted vessel with high blood volume
A dilated vessel with low blood volume
A constricted vessel with low blood volume
Answer:
a constricted vessel with high blood volume
Explanation:
because the size or area within affected blood vessels is reduced by vasoconstriction. Therefore, the blood flow is often decreased as blood vessel pressure is lower. The pressure or power of blood flow is increased at the same time, which results in higher blood pressure is the force exerted by this.

How many nucleotides equals 1 amino acid ?
Answer: Three nucleotides
Explanation: Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids.
A codon is a group of three nucleotides in DNA or RNA that is used to encode genetic information. Each codon represents a particular amino acid or a signal to cease the production of proteins. Thus, there are three nucleotides for every amino acid in the interaction between them.
Here is a more thorough justification:
The genetic code is made up of codons, which are groups of three nucleotides apiece. Four distinct nucleotides—adenine (A), cytosine (C), guanine (G), and thymine (T) in DNA, or uracil (U) in RNA—can be combined to create a total of 64 potential codons (43).
These codons act as informational units that specify the use of particular amino acids while synthesizing proteins.

Explanation:
shifts
When an earthquake occurs an area of the crust will move very suddenly and with a great release of energy. The point of the actual rock rupture is called the focus . The focus is usually found far beneath the surface. The point directly above the focus on the surface of the Earth is called the epicenter.
Answer: When an earthquake occurs an area of the crust will move very suddenly and with a great release of energy.

Which statement best describes genetic material?
Answer:
Genetic material, including genes and DNA, controls the development, maintenance and reproduction of organisms. Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes).
Explanation:
I hope this answer help you
Genetic material controls organism development, maintenance, and reproduction. Chemical units carry genetic information from generation to generation. Therefore, (B) is correct.
What is genetic material?The component of the cell that stores the information that can be passed down from generation to generation is referred to as the genetic material. The information that the cell needs in order to build proteins is stored in the genetic material, which is the genetic material's most significant function.
The development, maintenance, and reproduction of organisms are all under the control of their genetic material, which includes genes and DNA. The information contained in a person's genes is handed down from one generation to the next in the form of inherited units of chemical information.
Therefore, option (B) is correct because genes are sections of the genetic material known as deoxyribonucleic acid (DNA), which contain the instructions for making a particular protein.

[ANSWER]
Explanation:
When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.
consider the following at 8 p.m. a diabetic is found to have a blood pH of 7.33 is Brian tells his diaphragm to contract more frequently so that his breathing rate increases consider how is considering homeostasis is restored what effect would this have on his PH range is hicity and hydrogen ion concentration .
Answer:
Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.
Medical Disclaimer: The information on this site is for academic purposes only and is not a substitute for professional medical advice.
Explanation:
Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.
In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.

Where the cell divides
Explanation:
I think the equator, or equatorial plate, is the midline of the cell where duplicated chromosomes position during mitosis.
The equator of a cell is where equator divides.
Cell:
Cell is the basic unit of life. There are two types of cell : prokaryotic cell and eukaryotic cell. Cell divides by the process of mitosis and meiosis. Mitosis is an equational division and meiosis is reductional division.
Cell division is important for cell growth and division. Cell division starts at the nucleus. In nucleus there are different chromatin material. Chromatin condensed and form a chromosome.
Cell division starts at the equator of the cell. There are four phases : Prophase, metaphase, anaphase and telophase. During metaphase all the chromosome align at the equator.
Therefore, The equator of a cell is where equator divides.

Highly sensitive cells within the hypothalamus that react to changes in blood composition and cause the release of antidiuretic hormone (ADH) when appropriate are called.
Answer:
osmoreceptors
Explanation:
Osmoreceptors are nerve cells (neurons) capable of detecting changes in the extracellular fluid (ECF) osmolality, i.e., in the amount of solute in free water within the ECF. Osmoreceptors are known to contribute to osmoregulation by controlling body-fluid balance. These sensory receptors are mainly localized in the hypothalamus of homeothermic animals where they detect variations in the osmotic pressure and stimulate the release of antidiuretic hormone (ADH) in blood in response to the increase in plasma osmolality.
