atomic mass and number of neutrons.
C.
atomic symbol and number of protons.
D
atomic
and number of protons.
Answer:
C. atomic symbol and number of protons.
Explanation:
number of protons in the nucleus, but differ in the number of neutrons. The nucleon number is equal to the total number of protons and neutrons in the nucleus. ... The atomic mass number A is equal to the total number of protons and neutrons.
Two isotopes of the same element must have the same atomic symbol and number of protons.
ISOTOPES:
Isotopes are atoms of the same element with the same atomic number and chemical identity but different atomic masses. The forms in which atoms of a particular element exists is referred to as its isotope.The sole difference between isotopes of the same element is the number of neutrons each contain, which is responsible for the difference in masses. This means that isotopes of the same element must have the same atomic symbol and number of protons. For example, Carbon has two isotopes namely: C- 14 and C- 12 with both possessing atomic number 6 and symbol C.Learn more: https://brainly.com/question/21536220?referrer=searchResults

Answer:
i got you!
Explanation:
Cell theory is basically living things that arw composed with one or more cells and is also the basic unit of life.
Cell organelles are structures within a cell that perform specific functions like controlling cell growth and producing energy.
Adaptations biological mechanism by which organisms adjust to new environments or to changes in their current environment
Prokaryote is a microscopic single-celled organism that has neither a distinct nucleus with a membrane
Eukaryote are organisms whose cells have a nucleus enclosed within a nuclear envelope

What is an example of reactivity?
A. A piece of paper being torn
B. A nail heating up
C. An ice cube melting
D. A bicycle rusting
Answer:
D. A bicycle rusting.
Explanation:
A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.
B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.
C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.
Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).
Answer:
Im pretty sure that it’s D.

What is the basic unit of a nucleic acid and what is it made of?
Answer:
Basic structure Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

Scientists cite evidence that Earth’s climate has been changing significantly over the past 50 years. They also argue that changes to Earth’s orbital path are NOT the cause of these significant changes to climate.
Which statement provides the strongest evidence in support of the scientists' argument?
a
Variations in Earth’s orbital path are consistent with accepted laws of planetary motion
b
Earth’s orbital path does not affect the amount of solar energy that Earth receives
c
Changes to Earth’s orbital path occur in a cycle that repeats every 100,000 years
d
Climate change cannot be demonstrated over a span of 50 years.
Answer:
c. Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.
Explanation:
If changes to Earth's orbital path occur in a cycle that repeats every 100,000 years, then it wouldn't make sense that Earth's climate has been changing over the past 50 years. This cycle repeats and is over a very long period of time, so the climate wouldn't be changing significantly.
Not sure if my explanation helps, if it's any more assurance, I just got that question on a test and got it wrong, the answer was "c."
The statement that provides the strongest evidence in support of the scientists' argument; c. Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.
Explain about the climate on earth?Earth is has an ever-changing climate and the variation in the orbit of earth results in natural changes such as seasons, which depend on the duration and intensity of the sunlight.
Known that Scientists cite evidence that Earth’s climate has been changing significantly over the past 50 years. They argue that changes to Earth’s orbital path are NOT the cause of these significant changes to climate.
Thus If changes to Earth's orbital path occur in a cycle that repeats every 100,000 years, then it wouldn't make sense that Earth's climate has been changing over the past 50 years.
This cycle repeats and will be over a very long period of time, so the climate wouldn't be changing significantly.
Therefore, The statement that provides the strongest evidence in support of the scientists' argument; c. Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.

A sample of unknown concentration is diluted by placing 0.2 mL into 9.8 mL of buffer and then 3 mL is placed into a standard 1x1 cm square cuvette. It is measured at 350 nm and the Abs is 0.3. The molar absorptivity is 12.3 L/mol*cm. What is the concentration of the undiluted sample (mol/L to 2 decimal places)?
Answer:
The answer is "[tex]4.875 \ \frac{mol}{l}\\[/tex]".
Explanation:
The molar absorptivity value is= 12.3 [tex]\frac {L}{mol \times cm}[/tex]
path length of cell = 1 [tex]\ cm[/tex]
Absorbance = 1.2
Using the beer's lambert law:
[tex]A = \varepsilon \ cl\ \ \ \ \ \ \ _{where} \\\\c= \frac{A}{ \varepsilon l } \\\\[/tex]
[tex]= \frac{1.2}{12.3 \times 1}\\\\= 0.0975 \ \frac{mol}{L}\\[/tex]
Claculating the concentration of the solution after dilution: [tex](m_2)= 0.0975 \ \ \frac{mol}{L}[/tex]
find out the dilution value before concentration :
The volume taken by the dilution: [tex](V_1) = 0.2\ ml[/tex]
The final volume after dilution:
[tex](V_2) = 9.8+0.2\\[/tex]
[tex]= 10 \ ml[/tex]
Formula:
[tex]\bold{M_1 \times V_1 = M_2 \times V_2} \\\\ M_1= \frac{M_2 \times V_2 }{V_1}\\\\[/tex]
[tex]= \frac{ 0.0975 \times 10 }{0.2}\\\\= \frac{ 0.975 }{0.2}\\\\ = 4.875 \ \frac{mol}{l}\\[/tex]

Reporting our results allows other scientists to build on our work. It also allows them to repeat our experiment to see if they get the same results. How does this selection contribute to the entire article? A by elaborating on ways that the scientific method has changed B by emphasizing a contrast between different results of the scientific method C by indicating the problems with reporting results of the scientific method D by illustrating the effects of the scientific method for other scientists
Answer:
D by illustrating the effects of the scientific method for other scientists
Explanation:
Science is a continuum of research efforts. Each new work builds on the results of earlier works. Such earlier works must be reproducible by other scientists who wish to obtain the same results.
Hence, following the scientific method in a scientist's research has an effect on other scientists as they try to reproduce such results obtained in order to advance the frontiers of knowledge.
