Explanation:
The gradual change in the species over the periods is called evolution. These changes help species to survive in nature and adapt to their surrounding.
The correct answer to the question is option D which is Similarities in a number of mates.
What is DNA?The molecule which stores all the genetic information of the body and regulates the formation of protein and hormones is called DNA.According to the question, the correct answer is option D because the number of mates can not help in the study of the evolution factor.
Hence, the correct answer is option D.

Make an observation about the average height of the beanbag. How does it compare with your calculated kinetic energies for each speed? Does the height of the beanbag increase in equal increments with each step up in speed? Record these qualitative observations in Table B.
Answer: The kinetic energy in the solid and liquid phases is the same. The kinetic energy of the substance's particles will depend on the volume of the substance. The particles have less kinetic energy in the liquid phase than they do in the gas phase. They vibrate so quickly that the particles ionize and become plasma.

The force of gravity on Planet Y is 5.3 m/s2. The force of gravity on Planet Z is 6.2 m/s2. A 10 kg object would: weigh more on Planet Y than on Planet Z weigh less on Planet Y than on Planet Z weigh the same on Planet Y as on Planet Z
Answer:
every thing would weigh less on planet y because weight = m(mass)g(gravity) and planet y is 5.3x10=53 and planet z is 6.2x10=62. 62 is greater than 53 so everything on planet y would weigh less than everything on planet z so the answer is b

Explanation:
A graph with horizontal axis time (seconds) and vertical axis position (meters). An orange line runs straight upward from 0 second zero meters. A concave blue line runs upward from the same point. Maia says that both lines on this position vs time graph show acceleration. Is she correct? Why or why not?
Answer:
Let's start by using the definition of acceleration. Acceleration is defined as the change in velocity over the change in time. In equation, that would be Δvelocity/Δtime. Based on the axes of the given graph, it shows the trend of position over time. So, the slope of the line and the curve shows the change of position over change of time, Δdistance/Δtime. In physics, this is the definition of speed or velocity. So, Maia is incorrect. Both curves show the speed or velocity of the object, and not acceleration. If the graph used a y-axis of velocity instead of position, then only at that instance, would be Maia be correct.
The difference between the two is, the straight line shows constant velocity while the curve line shows changing velocity.
Explanation:
Maria is incorrect because the line or curve shown in the graph gives value of velocity not of acceleration.
What is acceleration?Acceleration of any object is dfine as the rate of change in velocity with respect to the distance.
According to the question, graph is plotted between time and distance so slope of the graph gives the value of change in position with repect to the time and this is used to define velocity as:
v = dx/dt
So, maria is incorrect.

The manual is a gene.
The manual is a chromosome.
Each set of instructions is a protein.
Each structure is a gene.
Answer:
Explanation:The manual is a chromosome.
If the given scenario is used as a model for genetic information, then "the manual is a chromosome" is the correct statement. Therefore, option (B) is correct.
What is a chromosome?A chromosome can be defined as a long nucleotide sequence that consists of linear arrangements of genes. In a chromosome, each DNA strand comprises a nucleotide sequence that can encode proteins that are different genes.
The human body has 23 pairs of chromosomes and this unique structure of the chromosome does DNA tightly packed with histone proteins to fit in the cell and helps in giving stability to it. The unwound DNA of a single cell measures 6 feet, with this we can understand the need for packaging in the nucleus of each cell.
Chromosomes can be seen in cell division as they ensure that DNA will be divided between the daughter cells in the cell division. Even a little irregularity in the process can cause many deformities and diseases.
A chromosome can be considered as manual containing instructions for how to build various types of structures using a set of interlocking bricks means nucleotides.

Explanation:
Hello! Hope this helps!
One important measure of the rate at which a radioactive substance decays is called half-life, or t1/2. Half-life is the amount of time needed for one half of a given quantity of a substance to decay. Half-lives as short as 10–6 second and as long as 109 years are common.

If 12.4 mol of Ne gas occupies 122.8 L, how many mol of Ne would occupy 339.2 L under the same temperature and pressure? Record your answer in scientific notation using 3 significant figures.
Answer:
3.43×10¹ mol
Explanation:
Given data:
Initial number of moles = 12.4 mol
Initial volume = 122.8 L
Final number of moles = ?
Final volume = 339.2 L
Solution:
The number of moles and volume are directly proportional to each other at same temperature and pressure.
V₁/n₁ = V₂/n₂
122.8 L/ 12.4 mol = 339.2 L / n₂
n₂ = 339.2 L× 12.4 mol / 122.8 L
n₂ = 4206.08 L.mol /122.8 L
n₂ = 34.3mol
In scientific notation:

The effects of climate on ocean are:
A.They have warm and cool currents that affect weather on nearby land.
D.They make temperatures in nearby areas slightly milder.
Climate type of the ocean:As ozone harming substances trap additional energy from the sun, the seas are retaining more hotness, bringing about an expansion in ocean surface temperatures and climbing ocean level. Changes in sea temperatures and flows achieved by environmental change will prompt modifications in environment designs all over the planet.
Thus, options A and D are correct.
