Answer:
C
Explanation:
So, there are 2 different forms that DNA can be found in.
The more common form, where the DNA is loosly scattered.
There is a less common form, however, only found during cell division, which is a compacted form. The DNA is tighly wound in this case.
In the case of chromosomes, DNA is tightly pakced, and not loose.
Now, do they are do they not have protiens?
Well, heres another question, how does the DNA get compacted?
It has to wrap around histone protiens.
The logn strands of DNA wrap around many histone protiens, until the full length of DNA has been compacted.
So to answer the question, yes, there are protiens found in chromosomes(specificly histone).
This means the answer must be C, since chrosomes are both tightly bound, and contain protein.

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.
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.
Thus, option B) is the right answer.

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.
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.

This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs to
Answer:
Lophotrochozoans (it is a protostome)
Explanation:
Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.
When the larva and the adult form of an organism are different from each other this type of development is called indirect development. For example Porifers and platyhelminthis.

In the population of plant K, each plant has only red flowers or only white flowers. A farmer collected the seeds from plant K with red flowers to grow new plants. Explain why the new plants will have only red flowers
Answer:
nose
Explanation:
nosenosenosenosenosenosenosenosenosenosenose
The new plants will have only red flowers because the trait for red flowers is determined by a dominant gene, and all the plants in population K have the same homozygous genotype for the flower color.
In genetics, the flower color trait in population K is determined by genes present in the plants' DNA. There are two alleles, or gene variants, for the flower color: one for red flowers (let's call it R) and one for white flowers (let's call it r). The gene for red flowers (R) is dominant, meaning that even if only one copy of the gene is present in an individual's genotype (heterozygous), it will produce the red flower phenotype. On the other hand, the gene for white flowers (r) is recessive, which means it will only produce the white flower phenotype if two copies are present in the genotype (homozygous recessive).
In population K, all the plants have only red flowers, indicating that they must have the genotype RR. Since all the plants are homozygous for the dominant red flower gene (RR), when they reproduce, they can only pass on the dominant allele R to their offspring. As a result, all the new plants that grow from the seeds collected from these plants will also have the genotype RR and, therefore, express the red flower phenotype.
Since there are no plants in population K with the genotype rr (homozygous recessive), which is necessary for white flowers, there is no chance of white-flowered plants appearing in the new generation. Thus, the new plants will have only red flowers due to the uniformity of the homozygous dominant genotype in the original population.

X-ray crystallography is a very important process that is used to help identify the structure of molecules. What exactly does this process show?
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.

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
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.
