In human beings fertilization occurs in fallopian tube
Answer:
Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
Describe the difference between at atom and an ion in regards to their substaomic
particles
Answer:
difference between atom and ion
Explanation:
What is an Atom?
The smallest unit of matter. It is indivisible and consists of neutrons, electrons and protons. Atoms can take part in chemical reactions. Combination of atoms together forms molecule. Always the number of protons and electrons are equal. Independent life may or may not be feasible within a solution. Nucleus of the atom is formed by protons and neutrons. Surrounding the nucleus are the electrons.
What is an Ion?
Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions. If an atom is charged electrically it is considered an ion. If an atom contains maximum number of electrons than protons, then it is called anion. If an atom contains maximum number of protons than electrons, then it is called cation. Independent existence in a solution. When an atom gains or loses electrons, ion is formed.
To make you understand how atom and ion are different from each other, here are the some major differences between atom and ion:
What mass of carbon dioxide is produced from the complete combustion of 4.60x10^-3g of methane?
Answer:
Explanation:
CH4 + 2O2 ==> CO2 + 2H2O
mols CH4 = grams/molar mass
Using the coefficients in the balanced equation, convert mols CH4 to mols CO2.
Now convert mols CO2 to grams. g = mols x molar mass.
The green light emitted by a stoplight has a wavelength of 505 nm. What is the frequency of this photon? (c = 3.00 × 10⁸ m/s).
Answer:
5.9405*10^14 Hz
Explanation:
Remember the equation c=v*λ
v=frequency
λ=wavelength
By manipulating the equation, we can get it in terms of frequency:
c/λ=v
Now convert wavelength to meters (1nm=m*10^-9)
5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)
Use the manipulated equation:
(3.00*10^8)/(5.05*10^-7), which yields:
5.9405*10^14 Hz (or s^-1)
The frequency of the photon will be "[tex]5.9405\times 10^{14} \ Hz[/tex]".
According to the question,
Wavelength,
[tex]\lambda = 505 \ nm[/tex]or,
[tex]= 5.05\times 10^{-7} \ m[/tex]
As we know the equation,
→ [tex]c = v\times \lambda[/tex]
or,
→ [tex]v = \frac{c}{\lambda}[/tex]
By putting the values, we get
[tex]= \frac{3.00\times 10^8}{5.05\times 10^{-7}}[/tex]
[tex]= 5.9405\times 10^{14} \ Hz[/tex]
Thus the above answer is right.

Why would you expect the materials used to make pot holders to be poor conductors of heat?
Answer:
Pot holders are meant to protect your hand from the heat of the pot, and so it would need to be a poor conductor of heat in order to do its job correctly. Silicon dioxide is a solid at room temperature and methanol is a liquid.
In order for a light bulb to be turned on in a circuit, it must have what kind of switch?
Answer:
Both switches must be closed in order for the circuit to be complete and for the bulb to light. (This would indicate the 'armed' status of this burglar alarm.) Magnetic switches come in 2 varieties - "Normally Closed" and "Normally Open". These 2 terms describe the state of the switch when it is NOT being controlled by the magnet.

Answer:
180 degrees
Explanation:
sp hybridization generates orbitals that overlap linearly, generating a straight line. This leads to an angle measurement of 180 degrees.
explain why an atom can only emit specific wavelengths of light and not every possible wavelength
Answer:
The electrons in an atom can only occupy certain allowed energy levels to a lower one, the excess energy is emitted as a photon of light, with its wavelength dependent on the change in electron energy. This is why an atom can only emit specific wavelengths of light and not every possible wavelength.
Identify the one thing that you were most surprised by in the quiz. Explain
why.
Adhesion is the attraction of molecules of one kind for molecules of a different kind... water is adhesive because the water molecules are attracted to the straw and therefore adhere to it. Thus, adhesive forces are important for sustaining life. This is because of these forces, water can flow up from the roots to the tops of plants to feed the plant, allowing it to move against gravity through plant cells. Another example of why its important that water is adhesive is the movement of water to the tops of trees and the drainage of tears from tear ducts in the corners of your eyes. Or how water droplets stick to the end of the pine needles. These are all examples of adhesion.

Explain the process of ionization in at least 1 paragraph.
Brainliest goes to best explanation!
Explanation:
Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.

adjoa's gross salary for last month was ghs 4687.24. if ghs 421.78 was deducted from adjoa's salary pay,how much take home pay did adjoa earned this past month?
Since Ghs. 421.78 was deducted from Adjoa's salary pay, her take home pay is Ghs. 4265.46.
Given the following data:
Adjoa's gross salary = Ghs. 4687.24.Deduction = Ghs. 421.78Gross profit can be defined as the profit earned by a business after subtracting its cost of manufacturing and distributing goods from its total revenue (sales).
On a related note, gross salary is the amount of money earned by an individual before any deduction such as tax.
To find how much take home pay Adjoa earned this past month:
[tex]Take\;home = Gross\;salary - deduction\\\\Take\;home = 4687.24 - 421.78[/tex]

How do we find the atomic size of an atom?
Answer:
The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl2 molecule.
