The statement describing nucleic acid has been that nucleic acid provides the blueprint for the formation of proteins.
Nucleic acid has been the genomic material in the body that performs the function of storage of information. DNA and RNA are nucleic acids.
The proteins are the biomolecules that are composed of amino acid units bound by the polypeptide bond. The information for the correct sequence of binding of protein has resulted from the mRNA codes.
The correct sequence and folding results in the operational protein, that has been able to perform varying functions. The codes for the binding of protein have resulted from the blueprint consisting of nucleic acid.
Thus, nucleic acid performs the function of acting as a blueprint for the formation of proteins.

Explanation:
When [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].
What is a positron emission?In positron emission, also called positive beta decay (β+ decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.
When a proton is converted into a neutron then the positron emission takes place as follows.
[tex]^1_1p\;\rightarrow\;^1_0n\;+\;^0_+1e[/tex]
A positron is represented by the symbol. Therefore, when a positron emission occurs then the resultant nuclei atomic number decreases by a unit mass.
The general equation representing positron emission is as follows.
[tex]^M_ZA\;\rightarrow\;^M_Z_-_1 B\;+\;^0_+1e[/tex]
Hence, fluorine-18 decays by positron emission as follows.
[tex]^1^8_9F\;\rightarrow\;^1^8_8n\;+\;^0_+1e[/tex]
Therefore, when [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

pls answer thisss it's due today
Answer:
1.correct
3.correct
Explanation:
pls mark me as brainliest
Answer:
I believe A is the correct answer.
Explanation:
I note that another response includes C. as another correct answer. It is possible, but it depends on what is meant by "fixed shape." I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own. Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition. But a primary definition of gases is that that take on the shape of their container, not a shape of their own.
A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws). They may have interactions, and often do, but they are weak. That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.

In the cathode ray tube experiment, J.J. Thomson passed an electric current through different gases inside a cathode ray tube in the presence of
an electric field. In which two ways did this experiment change scientists' understanding of the atom?
O It showed that atoms combine in different proportions.
O It showed that atoms can be divided into smaller parts.
M It showed that all atoms of the same element are similar.
D
It showed that individual atoms could be destroyed
showed that all atoms contain electrons.
The two ways the cathode ray tube experiment changed scientists'
understanding of the atom was it showing that atoms can be divided into
smaller parts and all atoms contain electrons.
J.J Thompson was the scientist which performed the cathode ray tube
experiment and was able to ascertain it was negatively charged as a result
of it being deflected to the positive electrode.
His observation showed that the atoms contain sub-atomic particles called
electrons which are negatively charged.

When a solid air freshener gets smaller over time and runs out is it a physical change or chemical change? please say why?
Answer:
i think this would be an example of a physical change because here the substance is changing directly from a solid to a gas without passing through the liquid state which means that the composition of the substance has not changed and remains the same. This is also called sublimation.

how much heat is released when 32g of water cools from 46°C and freezes
The amount of heat released when 32g of water cools from 46°C and freezes is 6182.4 J
Heat: This is a form of energy that brings about the sensation of warmth. The S.I unit of heat is Joules (J)
⇒ Formula:
Q = cm(t₂-t₁).................. Equation 1⇒ Where:
Q = amount of heat releasedc = specific heat capacity of waterm = mass of watert₁ = Initial temperaturet₂ = Final temperatureFrom the question,
⇒ Given:
m = 32 g = 0.032 kgt₁ = 46 °Ct₂ = 0 °C (Freezing point)c = constant = 4200 J/kg.°C⇒ Substitute these values into equation 1
Q = 0.032(4200)(0-46)Q = -6182.4 JNote: The negative sign tells that heat is released and as such can be ignored.
Hence, The amount of heat released is 6182.4 J

An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration?
The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].
The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.
After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.
