The atomic number of carbon is six, which means that a carbon atom has six protons. Carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. Which of these statements are true about carbon and its isotopes? Select all that apply.
A. All carbon atoms have six neutrons.
B. All carbon atoms have six protons and six electrons.
C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons.
E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons.

Answers

Answer 1

Answer:

B and D

Explanation:

Since it says all carbon atoms have six electrons, we know that they only have six protons too. The carbon 13 and 14 means they have extra neutrons that increases their atomic mass.

Answer 2

Answer:

How is static electricity created?

a. Two objects that are both positively charged repel each other and release
electric energy.


b. Two objects that are both negatively charged become attracted and create a
spark.

c.
Two highly conductive materials are placed within close proximity of one
another.
d. Friction between two objects causes a transfer of electrons from one object to
the other.
.

Answers

Answer:

d

Explanation:

So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.

The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.

Answer:

d. Friction between two objects causes a transfer of electrons from one object to  the other.

Explanation:

If electrons are transferred by rubbing two objects together, the result of the friction is that one object becomes positively charged by losing electrons, and the other object becomes negatively charged by gaining them. This is known as static electricity.

Which is the role of restriction enzymes?
to isolate the selected gene
to cut DNA into fragments of different lengths
to move and separate the strands of DNA
to join the sticky ends of DNA fragments

Answers

Answer:

to cut DNA into fragments of different lengths

Explanation:

A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.

More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. In live bacteria, restriction enzymes function to defend the cell against invading viral bacteriophages. Restrictions sites in the viral genome (a "happy accident" of nature, as far as the bacteria are concerned, since they don't appear to have any specific function in the virus) are cleaved by the bacterium's restriction enzymes, fragmenting and destroying the DNA of invading bacteriophages before it can incorporate into the host's genome and take over the cell.

A bacterium is immune to its own restriction enzymes, even if it has the target sequences ordinarily targeted by them. This is because the bacterial restriction sites are highly methylated, making them unrecognizable to the restriction enzyme.

Isn't evolution fantastic?

The correct answer is option C i.e. to cut DNA into fragments of different lengths.

what is  restriction enzyme?

A restriction enzyme is a bacterial protein that cleaves DNA sequences at sequence-specific places, resulting in DNA fragments with known sequences on both ends.

Certain laboratory processes, such as recombinant DNA technology and genetic engineering, require the use of restriction enzymes.

There are four different types of restriction enzymes: type I, II, III, and IV, which differ principally in structure, cleavage site, specificity, and cofactors.

Both restriction and methylase functions are carried out by a single big enzyme complex in Types I and III enzymes.

The restriction enzyme is independent of its methylase in the Type II system.

Several thousand type II restriction enzymes have been identified from a variety of bacterial species.

These enzymes recognize a few hundred distinct sequences, generally four to eight bases in length.

Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.

Type IV restriction enzymes cleave only methylated DNA and show weak sequence specificity.

hence, the correct answer is option B.

Explanation:

In an atomic model, the atomic particles has the nucleus which is located at the center of the particle. This nucleus contain positive charge which is called proton at the center and the neutrons(no charge). The electrons is located out side the particle she'll or nucleus and atomic particles become neutral because the number of protons is equal to the number of electrons which is negatively charge orbiting outside the nucleus.

What is osmosis?

Osmosis has been the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of the osmosis movement of the water takes place.

There are mainly three types of the osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis has been passive transport as water moves from low solute concentration to high solute concentration.

Osmosis has been also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.

Two differences between hormones and the nervous system

Answers

Answer:

Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.

Explanation:

Answer:

the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
