What is the atomic number of an element with 12 protons, 10 neutrons and 12 electrons?
Answer:
12 protons, 12 neutrons, 10 electrons
This is a magnesium Ion. There are 12 protons from the magnesium atom. There are 10 electrons because 12-2 = 10. There are 12 neutrons because 24-12 = 12.
Explanation:
The atomic number or nuclear charge number of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number or the number of protons found in the nucleus for every atom of that element.
In above question following details are mentioned:-
The number of proton is give by 12
The number of neutrons is given by 10
Then number of electrons is given by 12
From above data we can conclude that this is a magnesium ion.
Since, we know that atomic number is always equal to number of protons.
Here we can see that the number of protons is 12 so atomic number is always equal to 12.
So, we can say that atomic number of magnesium is 12
Therefore, the atomic number or nuclear charge number of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number or the number of protons found in the nucleus for every atom of that element.

The mammoth, which was very hairy, and the elephant, are both thought to have evolved from a scantily haired ancestor. Explain, as fully as you can, how the mammoth evolved from the common ancestor. (5)
Answer:
Evolution occurs about 6 million years ago.
Explanation:
The mammoth evolved from the common ancestor because evolution occurs about 6 million years ago. The modern elephants and woolly mammoths share a common ancestor and they are split into two separate species about 6 million years ago due to change in genetics as well as environment that leads to the evolution in the elephants.
Explain very simply how the X-ray diffraction process aids in solving structures of biological molecules.
Because x-rays and covalent bonds have a similar wavelength, x-ray crystallography currently offers the finest depiction of protein structure because it can show the accurate three-dimensional positions of the majority of atoms in a protein molecule.
What is X-ray diffraction?X-ray crystallography is an experimental science that determines the atomic and molecular structure of a crystal. In this experiment, the crystalline structure of the crystal causes a beam of incident X-rays to diffract into many specific directions, which allows the scientist to determine the atomic and molecular structure of the crystal.
Because x-rays and covalent bonds have a similar wavelength, x-ray crystallography is currently the method that provides the best visualization of protein structure. This is because it can reveal the precise three-dimensional positions of most of the atoms that are contained within a protein molecule.

Why might it be harder to convince people of the value of forest ecosystem services as opposed to the value of it's economic service?
Answer:
The importance of natural forest ecosystems to human well-being can not be overstated. Forests provide raw materials for food, fuel, and shelter. In forests, ecosystem components such as micro-organisms, soils, and vegetative cover inter-act to purify air and water, regulate the climate and recycle nutrients and wastes. Without these and many other ecosystem goods and services, life, as we know, would not be possible.
Explanation:
A metabolic pathway in a bacterium is under the control of an activator protein. This protein is made constitutively and activates transcription by binding to an activator binding site on the DNA, which allows RNA polymerase to bind to the promoter. The sketch below shows the arrangement of genes in the operon for this metabolic pathway. which of the statements below describes the cellular events most likely taking place when the cell needs to shut down this pathway
Answer:
c
Explanation:

A product of the reaction catalyzed by enzyme 3 binds to the activator protein, which inhibits its binding at the activator site. Therefore, option (C) is correct.
What is feedback inhibition?Feedback inhibition is a type of regulatory mechanism that occurs when the product of a reaction catalyzed by an enzyme inhibits the activity of that enzyme. This can be achieved through various mechanisms, such as by binding to the enzyme and preventing it from interacting with its substrate, or by modifying the enzyme in a way that changes its activity.
Feedback inhibition is a common mechanism used by cells to regulate pathways and ensure that they are operating at the appropriate level. For example, if a cell produces too much of a particular enzyme's product, that product may bind to the enzyme and inhibit its activity, thereby reducing the overall rate of the pathway. This helps to prevent the buildup of unnecessary intermediates or end products, and it can also help to conserve energy and resources.

Do you think it is possible to exploit the biological process of protein synthesis to make human proteins in the lab
Answer:
Yes.
Explanation:
Yes, it is possible to exploit the biological process of protein synthesis to make human proteins in the lab by the use of genetic engineering technique. DNA is the code or instructions that the cells use to make proteins so if a human protein is combined with a specific bacteria, so the bacteria is able to produce protein instructed by the DNA of the cell.
It is possible to exploit biological processes of protein as a result of proteins
having unique nucleotide sequences in its DNA.
Proteins are organic compounds which help in the building of cells and
replacement of worn out tissues. Proteins comprises of amino acids which
have unique nucleotide sequence which codes for their different types.

Answer:
The correct answer would be - Artery.
Explanation:
In the accident of the boy, his large blood vessel of the hand is cut which is deep, and the blood spurts out every few seconds. The blood tends to spurt due to the arteries are influenced by the heart pumping blood with force and arteries have more pressure due to force exerted on it in comparison to the veins.
Therefore, if the artery has a deep cut the blood spurt out as it has more pressure and will not clot easily.

Explanation:
individuals with marfan syndrome have a mutates gene in chromosome 15 which causes many phenotpic abnormalities such as disproportionately long arms and legs, a weakened aorta, stretch marks in skin, and poor eyesight. the pattern inheritance that would best describe this genetic disorder is
Answer:
It is inherited following an autosomal dominant inheritance; in this way, the risk that the child of an affected father or affected mother will have the disease is 50%.
Explanation:
Marfan syndrome is a systemic connective tissue disorder, autosomal dominant, which means that statistically the probability that a patient's children are affected by the disease is approximately 50%, it is caused by mutations in the protein of the extracellular matrix fibrillin 1. This disease mainly affects the cardiovascular, ocular and skeletal systems. The elastic fiber has the function of distension and retraction, it is part of the extracellular matrix of the tissues and is composed of elastin and a network of microfibrils that serves as a framework for the elastin deposit and the assembly of the elastic fibers. This network of microfibrils is formed by fibrillin1, which is encoded by the FBN1 gene on chromosome 15q21, the defect of which is expressed through a dominant negative effect, that is, in heterozygotes, the mutant fibrillin1 destroys the assembly of normal microfibrils, possibly , by acting with the products of the normal allele.
