Which statement is true about
electrically charged particles?
A. neutrons are positive, electrons are negative
B. protons are negative, neutrons are positive
C. protons are positive, electrons are negative
Answer:
C
Explanation:
protons are positive neutrons are neutral and electrons are negative
In an electrically charged particles protons are positive and electrons are negative.
Neutron has a positive electrical charge?The charge on neutron is zero(no charge). The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another and so atoms are neutral. Protons have positive or negative?A proton carries a positive charge and an electron carries a negative charge.so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.Learn more about electrical charge here: http://brainly.brainly.com/question/1487561

What color would the bby and water turn with plants in the dark
Answer:
The water is drawn in the xylem through capillary action and is dispersed through out the entire plant from stem to tips of the leaves and petals. When the water is colored, the color from the water can stain the plant, especially if it is a light colored plant, such as the white petals on our flowers.

d: Once water flows into the ground, it is stuck there forever
Which of the following happens as a result of eutrophication?
a: excessive growth of algae b: increased bacterial growth c: decrease in oxygen levels d: all of the above
Answer:D,C,
Explanation:
Q1)Trees increase the ability of the soil to retain stormwater by absorbing water from the ground. The roots also help to break up compacted soil as they expand, allowing water to flow more easily downward into the groundwater level.
Q2) The Sun's energy drives the water cycle. The sun warms the ocean's surface and other bodies of surface water, allowing liquid water to drain and ice to sublime (transform from a solid to a gas). These solar-powered processes release water vapor into to the atmosphere.

a particle of oxygen has 8 protons and 8 electrons. is this an atom or an ion? what's the charge?
Answer: It is Atom and the charge would be postive.
Explanation: If the atom had 8 protons and 8 electrons (oxygen for example), knocking one of the electrons out, makes 8 protons and 7 electrons. The atom now has a net charge of +1 because the 7 electrons cancil the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
Hope this helps :) Can u plz mark me branliest :)
A particle of oxygen has 8 protons and 8 electrons in an atom and the charge on it is zero.
What is an atom?It is the smallest particle of matter composed of electrons and a nucleus of protons and neutrons.
What is an ion?It is an atom with a positive or negative charge due to either loss or gain of electrons.
Every atom tends to have a noble gas configuration for stability and they either tend to lose, gain, or share electrons to achieve it.
The oxygen atom generally gains 2 electrons to complete its octet and has a net -2 charge.

Which gene mutation would have the greatest impact on a protein's amino acid sequence?
Answer:
heyyy there fellow weeb, thought id help u with this.
Explanation:
The addition of 2 bases is the most severe of these mutations. Because of a triplet reading of the genetic code, a 2 base insect changes the code readings frame that causes a frameshift mutation that means that each amino acid is incorrect after the mutation's site.
Which is NOT true of magnetic
domains?
A. Magnetic domains are groups of aligned
atoms.
B. Magnetic domains are too small to be seen.
C. Magnetic domains are outside of a magnet.
The study of magnetic domains is defined as the micro magnetics. The Magnetic domains are outside of a magnet is not true. The correct option is C.
What is a magnetic domain?A magnetic domain is defined as a region within a magnetic material in which the magnetization is in a uniform direction. This indicate that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.
The magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron, nickel, etc. The domains are found to be oriented randomly if there is no external magnetic field.
Thus the correct option is C.

The types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation. Thus, option B is correct.
What is dehydration synthesis?
When the level of water has been decreased the phenomenon has been known as the dehydration and the types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation.
Enzymes has been known as the biological catalyst that has been speed up the chemical reaction that use to carries out in the body. Enzymes are the protein by the nature and there are number of the enzymes present in our body such as the salivary amylase, pepsin, renin, lyases, lygases etc
The main function of the enzyme has to make the metabolism fast as well as speed up the chemical reaction carried out in the body. The best example of the enzyme has been salivary amylase which has an enzyme and it is present in the saliva and helps in the digestion of food.

(B) The chromatids of each chromosome are
separated.
(C) The nuclear envelope breaks down.
(D) Both synapsis and crossing-over take place.
(E) The diploid number of chromosomes is
reduced to the haploid number.
Answer:
B) The chromatids of each chromosome are separated.
The chromatids of each chromosome being separated doesn't occur in
meiosis I.
Meiosis is a type of cell division that produces four unique daughter cells
as a result of it undergoing two rounds of cell division. It is the cell division
that produces sperm and egg cells.
The meiosis I stage involves the resegregation of the chromosomes in the
diploid cell which has previously undergone division. This then produces
four haploid daughter cells which have unique features.
