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.

Simplify the combined equation for photosynthesis by crossing out compounds that are both products and reactants. How does this equation compare to the general equation for photosynthesis (CO
Answer:
The simplified equation is as follows:
CO2 + H20 + light energy ---> glucose + O2
Comparing this simplified equation with the general equation of photosynthesis (CO2+ H2O + light energy → [CH2O] + O2), it can be concluded that the process of photosynthesis is a two-stage process, and that a combination of the reactions of the two processes gives the products of photosynthesis
Note: The question is incomplete. The complete question is given below:
Simplify the combined equation for photosynthesis by crossing out compounds that are both products and reactants. How does this equation compare to the general equation for photosynthesis (CO2+ H2O + light energy → [CH2O] + O2)?
Explanation:
Photosynthesis -the process by which plants use the energy of the sunlight to produce sugars- occurs in two stages: the light-dependent stage and the light-independent stage.
The light reactions occuring in the thylakoid membranes use the energy of sunlight to split water producing electrons which are transferred to NADP+ to produce NADPH and ATP from ADP and Pi
Light energy + H20 + ADP + Pi + NADP+ ---> 02 + NADPH + ATP
In the light-independent reactions occuring in the stroma, energy from ATP and NADPH in addition with carbon dioxide in the atmosphere is used to produce glucose
NADPH + ATP + CO2 ---> glucose + ADP + NADP+
The combined equation of the two reactions is given below:
CO2 + H20 + light energy + ADP + ATP + NADPH + NADP+ + ---> glucose + 02 + ATP + NADPH +ADP + NADP+
The simplified equation is as follows:
CO2 + H20 + light energy ---> glucose + O2
Comparing this simplified equation with the general equation of photosynthesis (CO2+ H2O + light energy → [CH2O] + O2), it can be concluded that the process of photosynthesis is a two-stage process, and that a combination of the reactions of the two processes gives the products of photosynthesis

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.

How is in vitro DNA synthesis in a test tube different than in vitro DNA synthesis in an automated synthesizer
Answer & Explanation: In vitro is used when DNA is synthesized in the lab, outside cells, in microtubes i.e., in an artificial environment outside of the living organism. Making DNA in a test tube (by hand) is very labor-intensive and takes a lot of time, whereas, the use of DNA synthesizers designed by companies allow for the production of DNA molecules in both small or large quantities and in far lesser time it would take to do so by hand, in vitro in test tubes.

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.

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.

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.

While studying environmental samples collected from the ground cover of the Amazon rainforest, you isolate a new microorganism. You note that it is single-celled, lacks a nucleus, and is found only in areas of the rainforest that remain humid year-round. Based on this information, how would you best describe this organism
Answer:
The organism is a prokaryote from the domain Archaea since it lacks organelles and lives in what can be considered an extreme environment.
Explanation:
The organism is single-celled and lacks a nucleus. Prokaryotic organisms generally lack nuclei and other membrane-bound organelles such as mitochondrion and chloroplast. Hence, both attributes are characteristic of a typical prokaryote although being unicellular is not exclusive only to prokaryotes.
Prokaryotes can be bacteria of Archaea. The organism, in this case, also lives in an area that is humid all year round. Such an area can be considered to be an extreme environment. Living in extreme environments is a characteristic that is peculiar to Archaea only.
Organisms in the Archaea domain are generally prokaryotic, unicellular, and live in extreme habitats such as hydrothermal vents, marshes, hot springs, etc.
