Which best explains the process of meiosis?
Meiosis includes cytokinesis, which divides the cell's DNA.
Meiosis is a series of steps that divides the cell's cytoplasm.
Meiosis includes interphase, which divides the cell's cytoplasm.
Meiosis is a series of steps that divides the cell's DNA.
Answer:
D
Explanation:
Meiosis is a series of steps that divides the cell's DNA best explains the process of meiosis. Therefore, option D is correct.
What is meiosis ?A type of cell division in which each daughter cell receives half the DNA of the parent cell. In mammals, meiosis occurs during the formation of egg and sperm cells.
Due to the fact that cell division occurs twice during meiosis, a single starting cell can produce four gametes (eggs or sperm). Cells go through four stages during each round of division: prophase, metaphase, anaphase, and telophase.
Meiosis is also important for allowing genetic diversity and facilitating the repair of genetic defects via recombination.
Daughter cells are diploid after meiosis and have twice as much genetic material, which can be divided in an infinite number of ways.
Thus, option D is correct.

hope that helps.↑Once upon a time, Walter the water molecule was traveling around Linda's blood. He was enjoying moving around wherever he wanted. One day, Walter decided to visit some cells. He traveled in and out of the cells as he pleased. Walter decided that he liked the cells so much that he wanted to stay inside and rest in the vacuole. However, as the day went on, Walter felt a change happening around him. Linda had eaten some VERY salty popcorn. Walter LOVED Sally the salt molecule and felt a magnetic attraction to her. The closer the salt came to the cell, the quicker Walter's love for Sally pulled him out of the cell and towards the salt.

This story that is related to the movement of water in relation to the amount of solute seeks to explain the process of OSMOSIS in a very interesting way.
Explanation:
The OSMOSIS process is a process where water diffuses from a compartment with fewer solutes to one with higher solutes, that is why the osmotic intention is to balance the concentrations and molarities between both compartments, this is called osmotic balance.
For this to happen, a highly water-permeable barrier is needed.
A large marble is dropped in a graduated cylinder with 45 mL of water in it. The water level increased to 61 mL. What is the volume of the marble?

With an average acceleration of 0.50 m/s?, how long will it take a cyclist starting from
rest to reach 13.5 m/s?
Answer:
t = 27 s
Explanation:
Given data:
Average acceleration = -0.50 m/s²
Time taken to reach to the 13.5 m/s = ?
Solution:
Formula:
Vf = V₀ + at
Vf = 0
V₀ = 13.5 m/s
a = -0.50 m/s²
Now we will put the values in formula.
0 = 13.5 m/s - 0.50 m/s²t
0.50 m/s²t = 13.5 m/s
t = 13.5 m/s / 0.50 m/s²
t = 27 s

Which quantum number describes the orientation of an orbital within a sublevel?
Explanation:
Each orbital within a particular sublevel is distinguished by its value of ml. This quantum number may be more aptly named the orbital orientation quantum number. In each energy sublevel (designated by l) there are 2l+1 possible independent orientations of the electron cloud.
Answer:
[tex]m_l-magnetic[/tex]
Explanation:
The principal energy level, n, tells us which shell it is in and the total energy of the electron.
The angular momentum (azimuthal), l, tells us which sublevel/subshells the electron is in.
The magnetic, m sub l, tells us the orientation the electron is spinning.
The bright red line from the emission spectrum of hydrogen has a wavelength of 657 nm. What is the energy, in joules, of a single photon of this light? 4.35 x 10–40 J 3.03 x 10–28 J 3.03 x 10–19 J 4.56 x 1014 J
Answer:
3.03 × 10^-19 J
Explanation:
The energy, E, of a photon of light can be calculated by using the formula:
E = hv
Where; E is energy in Joules,
h is Planck's constant {6.626×10^−34J}
v is frequency of light
For this question, the wavelength (λ) is given, not the frequency (v).
Hence, we use;
v= c/λ
Where v= frequency, c= speed of light (3×10^8m/s), λ= wavelength (657nm)
657nm = 657 × 10^-9m
v = 3×10^8/657 × 10^-9
v = 3/657 × 10^(8--9)
v = 0.00456 × 10^17
v = 4.56 × 10^14
Since frequency (v) = 4.56 × 10^14;
E = hv
E = 6.626×10^−34 × 4.56 × 10^14
E = 30.21 × 10^(-34+14)
E = 30.21 × 10^-20
E = 3.021 × 10^-19
Therefore, the energy of the photon of light is 3.02 × 10^-19 J

2. Calculate the density of a rock that has a mass of 21.58 grams and causes the water in a
graduated cylinder to rise from 20.0yl to 25.4 ml.
Answer:
4.00 g/mL
Explanation:
Density is mass divided by volume (g/mL).
Mass of rock = 21.58
Volume of rock = 25.4 - 20.0 = 5.4mL
Density of rock = 21.58g / 5.4mL = 3.99629 g/mL

The density of ice is 0.92 g/cm3 and the density of rubbing alcohol is 0.80 g/cm3. If an ice cube is placed in a container of rubbing alcohol, the ice cube will
Question 7 options:
a) float in the rubbing alcohol with none of the ice cube submerged.
b) sink to the bottom of the container.
c) move up and down in the rubbing alcohol.
d) float in the alcohol so that most of the ice cube is below the surface of the liquid.
Answer:
Option B. Sink to the bottom of the container.
Explanation:
From the question given above, the following data were obtained:
Density of ice = 0.92 g/cm³
Density of rubbing alcohol = 0.80 g/cm³
From the density of both substance given, we can see clearly that the ice has a higher density when compared with the rubbing alcohol.
Thus, If an ice cube is placed in a container of rubbing alcohol, the ice cube will not float rather, it will sink to the bottom of the container because the ice has a higher density than the rubbing alcohol.

When 38 g of a metal at 92 °C is added to
43 g of water at 22°C, the temperature of the
water rises to 30°C. What is the specific heat
capacity of the metal? Assume no heat was
lost to the surroundings.
Answer in units of
J/g degrees C
The specific heat capacity of the metal : 0.610 J/g° C
Further explanationThe law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q abs = Q received
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
∆T = T(final temp) - T(initial temp)
mass of metal = 38 g
T initial metal = 92 °C
mass of water = 43 g
T final water = 30 °C
T initial water = 22°C
c water = 4.18 J/g° C
Heat absorbed by water[tex]\tt Q=m.c.\Delta T\\\\Q=43\times 4.18\times (30-22^oC)\\\\Q=1437.92~J[/tex]
the specific heat capacity of the metalQ water = Q metal
[tex]\tt 1437.92=38\times c\times (92-30)\\\\c=0.610~J/g^oC[/tex]

Which of the following is a practice that shows you have intellectual honesty?
A. letting your beliefs influence your results
B. avoiding plagiarism of the works of others
C. making up data to support a special cause
D. copying the work of other scientists and claiming it as your own
Answer:
Avoid plagiarism and the work of others
Explanation:
I took the test and got it right. Hope this helps :)
Avoiding plagiarism of the work of others shows that you have intellectual honesty. So the correct option is B.
What is plagiarism?
The act of presenting someone else's ideas or work as your own, with or without that person's agreement, by integrating it into your work without giving it due credit, is known as plagiarism. This definition applies to all works, both published and unpublished, whether they are in manuscript, print, or electronic form.
Plagiarism can be willful, careless, or accidental. Plagiarism that is deliberate or careless is prohibited under exam regulations and is grounds for disciplinary action. In addition to text, additional media such as computer code, pictures, graphs, etc. must also include credit for the ideas and works of others.
It equally applies to both published and unpublished text and data taken from books and journals, lectures, theses, and other students' writings. Text, information, or other materials that you take from websites must also be credited.
Learning and using the rules of good academic practice from the start of your university career is the best way to prevent plagiarism.
Therefore the correct option is B.
