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.

The following dot plot represents the litter sizes of a random sample of labrador retrievers.
Calculate the mean, median, and mode for this set of data.
Calculate the range, interquartile range, and mean absolute deviation (rounded to the nearest hundredth) for this set of data. For the mean absolute deviation, do not round the mean.
Make two inferences about the litter size of labrador retrievers.
Answer:
12
Explanation:so the mean deviation is for the square and the square is for you so you keep the square and add it.
Answer:
1. mean: 7.78 median: 8 mode: 7
2. range: 9 interquartile range: 2 MAD: 4.5367
3. The range is about 4 times bigger than the interquartile range. The mean is around double the MAD.

what type of lens is shown -covex lens
-this isnt a lens
concave lens
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Lens and Ray Optics.
We must understand the Concept that,
1.) When a beam of parallel light pass through a Convex lens, all the rays get deviated and converges to a special point at the axis that is a Focus.
2.) When a beam of light passes through the Concave lens,the light beams diverge from one another forming a virtual focus in the primary side of lens,
Hence the above given diagram beam rays are diverging, it is a CONCAVE LENS
answer is C.) Concave lens

what's the difference between viscosity and flow rate
Answer:
Flow rate is how fast a fluid moves. The flow rate can depend on several factors. These factors are the type of fluid that you are using, the force that is pushing on a fluid, the size of the pipe the fluid flows from and the type of surface the fluid flows over. Viscosity is the resistance of a fluid to flow.

Which of the following diagrams represents a single
replacement reaction?
Explanation:
i think the answer is....b
The diagram that represents single replacement reaction is:
b.
Single replacement reaction:This reaction is also known as displacement reaction. It is a reaction in which one element is substituted for another element in a compound. When a replacement reaction occurs, a new aqueous compound and a different pure element will be generated as products. For example:
[tex]2HCl(aq)+Zn(s)--->ZnCl_2(aq)+H_2(g)[/tex]
Thus, option b is correct.

Deep, cold water has __________. Warm, shallow water has ___________.
low density; low density
high density; high density
low density; high density
high density; low density
Answer:
Deep cold water has a high density and warm, shallow water has a low density.
Explanation:
Because when it is cold, water shrinks together it acts as a factor for it to have a high density and it's deep which also acts as a factor because to deeper something is near the Earth's core the more pressure it has leads to high density as well because gravity is stronger near the Earth's core. When water is warm it has a low density which is the first factor and because it is shallow it is far from the earth's core it has a lower density and pressure.

Which of the following choices shows the correct Lewis electron-dot diagram for a molecule of chlorine, Cl2?
Answer: 2!
Explanation:
The best lewis structure for [tex]Cl_2[/tex] is in option 2.
Na or sodium is the cation in the reactant.
Cl or chlorine is the anion in the reactant side.
NaCl is the product of the reaction.
Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.
Chlorine is a group VIIA element in the periodic table and contains seven electrons in its last shell.
Valence electrons are given by chlorine atoms = [tex]7\times2=14[/tex]
Total valence electrons = 14
So, each of Cl is surrounded by three pairs of dots, connected by a single line. So, the best lewis structure for [tex]Cl_2[/tex] is in option 2.
