5 Facts about cell division
Answer:
Cell division is the process by which a cell, called the parent cell, divides into two cells, called daughter cells.[1] When the cell divides, everything inside it divides also. The nucleus and the chromosomes divide, and the mitochondria divide also.
In mitosis, an ordinary body (somatic) cell divides to make two daughter cells.
In meiosis, a cell divides twice, to produce four gametes (sex cells). The first division of meiosis is a special kind of cell division called a reduction division because the number of chromosomes is halved. The second division of meiosis is similar to mitosis.[2]
Three types of cell division: left is binary fission as in bacteria; right are mitosis and meiosis as in eukaryotes.
Cells are the 'building blocks' of life, and cell division is a basic feature of life. For simple unicellular organisms like Amoebozoa, one cell division reproduces the entire organism. On a larger scale, cell division can create offspring from multicellular organisms, such as plants that grow from cuttings. But most importantly, cell division enables organisms that are able to sexually reproduce to develop from the one-celled fertilised egg (zygote). Cell division also allows for continual renewal and repair of the organism.
The cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.
What is cell division?It is the process by which cells divide into daughter cells. This keeps the cell organism to survive.
The five facts about cell division are:
The cell division has 4 phases.In prophase, the cell DNA condensed to form chromosomes.In metaphase, the chromosomes are aligned in the middle of the cell.In anaphase, the chromosomes move towards the different poles.In telophase cells divide into two daughter cells.Therefore, the cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.

Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill
Answer:
The rollercoaster has the lowest kinetic energy at the top of the hill.
The rollercaoster has the highest kinetic energy at the bottom of the hill.
Explanation:
The kinetic energy of any solid body in motion is usually computed using this formula:
K.E = [tex]\frac{1}{2}mv^2[/tex]
From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.
We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.
This means that the variations in the K.E are mainly coming from its velocity.
At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.
However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.
How do the mass number and atomic change as a particle goes through beta decay
Answer:
The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus
Hope this helped!

How is it possible for scientists to know the composition of stars without traveling to the star?
Answer:
One of the most common methods used today to determine the composition of stars is spectroscopy.
Explanation:
Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation.

What holds solid parties together?
Answer:
The cool people like me XD
Explanation:
Answer:
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart.

Q3. When copper (II) chloride reacts with silvernitrate, copper (II) nitrate and silverchloride are formed.Write the balanced equation for the reaction given above:A.CuCl2(aq) + 2 AgNO3(aq) →Cu (NO3)2(aq) + 2 AgCl(s)B.CuCl2(aq) + NaNO3(aq) →Cu (NO3)2(aq) + AgCl(s)C.CuCl2(aq) + 2 NaNO2(aq) →Cu (NO2)2(aq) + 2 AgCl(s)D.CuCl(aq) + NaNO3(aq) →Cu NO3(aq) + AgCl(aq
Answer:
See explanation
Explanation:
When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.
After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;
CuCl2 + 2AgNO3 -------> Cu(NO3)2 + 2AgCl
Which statement about elements is true?
All substances are made up of elements.
There are approximately 50 elements.
An element is made up of different types of atoms.
Most elements are nonmetal.

Answer:
first one is right.
there are 117 elements, so 2nd option is wrong.
elements are made up of one type of atoms, so 3rd is also wrong.
most elements are metal. so 3rd is wrong
What is the formula for pH?
Answer:
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
Example: Find the pH of a 0.0025 M HCl solution.
