If you are pushing on a box with
5N, and the box pushes back 5N,
what would the net force be?.
ΑΟ
A. ON
B. 25N
C. 10N
Answers
The correct answer is A. 0N, as there is no net force acting on the box.
The net force in this scenario can be determined by calculating the difference between the applied force and the opposing force. In this case, if you are pushing on a box with a force of 5N, and the box pushes back with an equal force of 5N, the net force would be zero.
Net force is the vector sum of all the forces acting on an object. In this situation, the applied force of 5N is countered by the opposing force of 5N exerted by the box. Since the forces are equal in magnitude and opposite in direction, they cancel each other out.
When the net force is zero, it means that the forces are balanced, resulting in no acceleration or movement of the object. The box would remain at rest or continue moving at a constant velocity if it was already in motion.
Therefore, the correct answer is A. 0N, as there is no net force acting on the box.

X-ray crystallography is a very important process that is used to help identify the structure of molecules. What exactly does this process show?
Answers
Answer:
can reveal the precise three-dimensional positions of most atoms in a protein molecule because x-rays and covalent bonds have similar wavelength, and therefore currently provides the best visualization of protein structure.
Because x-rays and covalent bonds have comparable wavelengths, they can now give the finest imaging of protein structure because they can reveal the precise three-dimensional locations of the majority of atoms in a protein molecule.
What is X-ray crystallography?
X-ray, a scientific technique called crystallography may be used to map out the atoms of a crystalline material in three dimensions. By using most crystalline materials' interatomic gap as a diffraction gradient for x-ray radiation, which has wavelengths on the order of 1 angstrom, this method makes use of the interatomic spacing of most crystalline solids.
Wilhelm Rontgen made the discovery of x-rays in 1895. Up until 1912, there remained disagreement about whether x-rays constituted electromagnetic energy or particles. Researchers recognized that this light's wavelength would need to be in the range of 1 Angstrom (A) if the wave theory was accurate.
It would be necessary to use a gradient with separation on the same order of magnitude as the light for diffraction and measurement of such tiny wavelengths.
To diffract the x-ray beams, the arrangement of the atoms must be in an ordered, periodic form. The specific arrangement of atoms in that crystal is then revealed through a sequence of mathematical computations to create a diffraction pattern. The principal technique still in use today for studying the structure and bonding of organometallic compounds is X-ray crystallography.
Therefore, since x-rays and covalent bonds can display the precise three-dimensional locations of the majority of atoms in a protein molecule, they provide the best imaging of protein structure currently achievable.

Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
Answers
answer:
a balance and a graduated cylinder
Explanation
Density is mass per unit and it is property characteristic of a substance. The arrangement of the mass of atoms and their size is what determines the the density of a substance.
For a student to measure the density of seawater he/she is required to use a balance and a graduated cylinder where a balance will be used to measure the mass of the mineral sample and then a graduated cylinder to determine the volume.

The enzyme could become spatially distorted, thus reducing the ability of the active site to catalyze the reaction. Tight enzyme-substrate binding will reduce the forward rate constant for the reaction. Tight binding of the enzyme to its substrate will pull the substrate out of solution, thus decreasing the driving force for the forward reaction. Tight binding of the enzyme to its substrate will result in the enzyme-transition state complex being higher in energy than with weaker binding. All of the above.
Answers
Answer:
All of the above.
Explanation:
All the given options are the potential disadvantage of an enzyme that have a very high affinity for its substrate.
The enzyme can be distorted spatially and thus reduces the ability to catalyze the reaction of the active site.
The tight binding of an enzyme to a substrate results in enzyme transition state complex which is higher in energy.
The tight binding also pulls the substrate out of the solution and decreases a driving force in the forward reaction.

7 biceps: striated
8 trapezius: striated
9 stomach: smooth
10 gastrocnemius: striated
Explanation:
Striated muscle is a type of tissue composed of repeated functional units called sarcomeres, which are the basic contractile unit of the muscle fiber. The striated appearance is caused by repeating bands of actin and myosin proteins. Striated muscle tissue is subdivided into two major parts: 1-cardiac muscle and 2-skeletal muscle. Skeletal muscle is a highly dynamic tissue that is mostly attached by tendons to the bones in the skeleton. This voluntary tissue (skeletal muscle tissue) is composed of multiple fascicles or bundles of muscle fibers. Moreover, cardiac muscle tissue, also known as myocardium, is a type of striated muscle that contracts and releases involuntarily, composed of cells called myocytes present in the heart. Finally, smooth muscle is a type of involuntary and non-striated muscle tissue localized within the walls of organs/structures (i.e., intestine, esophagus, stomach, uterus, urethra, bladder, blood vessels, etc.).

Which statement describes Mendel’s hypotheses regarding gametes?
A) gamete carries two genes for a trait.
B) gamete carries one allele for a gene.
C) gamete can carry multiple alleles for a trait.
D) Some gametes are dominant and some are recessive.
Answers
Answer:
The correct answer is B. A gamete carries one allele for a gene.
Explanation:
Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to the Law of segregation given by Gregor Mendel-
During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.
