Answer:
A. Offspring are genetically identical to the parent.
That's the answer. I hope it helps!
The statement which describes asexual reproduction but not sexual
reproduction is A. Offspring are genetically identical to the parent.
What is Asexual Reproduction ?Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.
The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent.
An Asexual reproduction means that the parent organism will simply split into two child organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA.
Therefore the child and the parent organism will contain exactly the same genetic material - the correct answer is A.

Why do the atoms in a piece of copper metal have no net charge?
1.The charges of the positive and negative copper ions cancel each other out.
2.The number of electrons surrounding each copper nucleus doesn’t change.
3.Copper atoms can’t lose electrons without a substance present to gain electrons.
4.When a copper atom loses electrons, it also loses a corresponding number of protons.
5.The copper atoms exchange neutrons instead of electrons.
Answer:
The correct answer is the charges of the positive and negative copper ions cancel each other out.
Explanation:
A copper metal having no net charge means that it is a neutral atom. A neutral atom means that total number of protons is equal to the total number of electrons.

If we start with 20 atoms of plutonium – 239, how many would remain after 48,240 years?
The amount of atoms of plutonium – 239 that would remain after 48240 years is 5 atoms
How to determine the number of half-lives Half-life (t½) = 24100 yearsTime (t) = 48240 yearsNumber of half-lives (n) =?n = t / t½
n = 48240 / 24100
n = 2
How to determine the amount remaining Original amount (N₀) = 20 atomsNumber of half-lives (n) = 2Amount remaining (N) = ?N = N₀ / 2ⁿ
N = 20 / 2²
N = 20 / 4

what is difference between dipole dipole interaction and hydrogen bonding
Answer:
A dipole-dipole force is when the positive side of a polar molecule attracts the negative side of another polar molecule.
A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule.
Answer:
Hydrogen bonds are dipole-dipole interactions in which at least one of the atoms involved is a hydrogen atom. Dipole-induced dipole bonds are those electric bonds that exist between a molecule with a permanent dipole moment and a molecule in which a temporary dipole moment has been induced.

copper sulphate solution turns the colour of litmus into red but litmus changes into blue with baking soda solution although both are salts. Give reason why?
Answer:
Copper sulphate is an acidic salt: It is the product of the reaction between a weak copper base and a strong acid , H2SO4
Litmus has a red colour in acidic solutions:
Conclusion: Acidic copper sulphate solution turns blue litmus to red
Baking soda is a basic salt : It is the reaction product of a weak acid , CO2 and a strong base , NaOH
Litmus has a blue colour in basic solutions:
Conclusion: basic baking soda solution turns red litmus to blue

Why does lithium have a higher ionization energy compared to sodium?
Answer:
There are 11 protons in a sodium atom but only 3 in a lithium atom, so the nuclear charge is much greater. ... The only factor left is the extra distance between the outer electron and the nucleus in sodium's case. That lowers the ionization energy.

A brand of soda has one of the highest quantities of sugar among popular soda drink packing 52 grams into each 12 oz can how many molecules of sugar are in one can of this soda
Answer:
9.0 × 10²² molecules of sugar (sucrose)
Explanation:
Step 1: Given and required data
Mass of sugar in each can of soda (m): 52 gMolecular formula of sugar (sucrose): C₁₂H₂₂O₁₁Molar mass of sucrose (M): 342.3 g/molStep 2: Calculate the moles of sugar (n) in each can
We will use the following expression.
n = m/M = 52 g / (342.3 g/mol) = 0.15 mol
Step 3: Calculate the molecules corresponding to 0.15 moles of sugar
We will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.
0.15 mol × 6.02 × 10²³ molecules/1 mol = 9.0 × 10²² molecules
How do animal behaviors, such as hibernation or migration, enhance their survival?
Answer:
the reason a lot of animal ether hibernate is because they are escaping the cold or looking for food and the only reason we Humans don't hibernate is for two reasons. Firstly, our evolutionary ancestors were tropical animals with no history of hibernating: humans have only migrated into temperate and subarctic latitudes in the last hundred thousand years or so.
