which 3 statements of these are true? ( I put a picture attached to this ) please help I will give brainliest if correct
Answer:
The name of the element is carbon, there are 6 protons, and nitrogen has a smaller atomic number.
Explanation:
The atomic number of carbon is 6, not 12.
The atomic mass of carbon is 12.01g, not 12.
It does have six protons, it has a larger atomic number (6) than nitrogen (5) and it is called carbon.
A typical virus is made up of 2 parts. Check all that apply.
A) Golgi Body
B) Nuclear envelope
C) Nucleic Acid
D) Capsid
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.

Explanation:
What is the effect of inputting stem cells instead of body cells into the original system?
Explanation:
Stem cell research indicates that s.cells are cells that are not fully developed; in turn if researchers inject a patient with type 1 diabetes into the pancreas the result is that the pancreas produces it's own insulin eliminating the chances of spikes in the blood sugars of the patient & also long term effects of high blood sugars that effect all vital organs & nervous system.
Researchers were also using stem cells to limbs that were amputated or damaged resulting in the limb regenerating itself.
I have seen a mouse that had a human ear attached to its body.
Researchers were ordered by our government to cease the experiments because pharmaceutical companies were making more $$ on medicines to supposedly help diabetics or veterans to live a normal life..

Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.

Does the Second Amendment need to be "revisited" in 2021? yes and why?
I need help pleasee
Answer:
It needs to be revisited because of the random acts of violence that it enables.
Explanation:
People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control. If people did not have access to automatic firing machine guns, less people would have died.

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.

a student mixed a sample of urine from a person with benedict's solution and heated ,the colour changed to Orange. (b)what did the student conclude on the health status of the person
Answer:
The person has high blood sugar.
Explanation:
Because benedict's solution tests for reducing agents, and since it changed its colour, reducing sugars(like glucose) is present.

What makes mitochondrial DNA useful as a molecular clock? (2 points)
It is only found in select organisms, making it easier to compare relationships between species that have it.
A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations.
Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other.
A slow mutation rate makes it useful for determining evolutionary relationships between ancient species.
Answer:
Mitochondrial DNA is useful as a molecular clock because it displays uniparental inheritance

Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?
Answer:
She should immediately rinse or flush her eyes with water.
Explanation:
One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.
Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.
Answer:
proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

draw a line from each hormone in list A to the correct information in list B
Answer:
The correct answer would be -
FSH - used as fertility drugs to makes egg mature.
LS - stimulates the release of eggs.
Oestrogen - causes the lining of the womb to break down.
Explanation:
FSH is a hormone released from the pituitary gland and is the abbreviation of Follicle-stimulating hormone which controls the menstrual cycle and growth of eggs in ovaries. It is also used as a fertility drug that promotes the growth of eggs to mature it.
LS or Luteinising hormone is the hormone that is released from the pituitary gland and promotes the surge of the release of eggs.
Oestrogen is the hormone that helps females during puberty during the menstrual cycle to breakdown the lining of the womb.
how cutting down trees contribute to global warming??
Answer:
Carbon is stored in the plant, which helps a plant to grow. But when trees are cut down and burned and or allowed to rot, their basically storing carbon dioxide, which then gets released into the air ... again known as carbon dioxide. In conclusion this is how deforestation or cutting down trees and including forests can lead to and or contribute to global warming.
