Answer:
A ribozyme is an RNA catalyst.
Explanation:
Ribozymes correspond to RNA molecules with enzymatic activity, mainly catalytic. These enzymes are specific and have limited activity, unlike protein enzymes.
The action of ribozymes is to promote the hydrolysis reaction of the phosphodiester bonds of a nucleic acid, specifically RNA. These enzymes are currently very useful in molecular biology, due to their potential to manipulate RNA.
Regarding other options:
RNA poymerase allows the construction of RNA chains, during transcription.Protein enzyme are the majority of enzymes involved in organic reactions, of a protein nature.Membrane protein are those that are integrated into the plasma membranes.which would stop electricity from flowing a) arubber band

The structure of a cell is most closely related to which of the following
A. The size of the cell
B. the function of the cell
C. The number of mitochondria in the cell
D. Whether the cell is living or not
Cells assume different structures primarily on the basis of the function with which they are associated. Thus, the correct option is B.
The number of mitochondria or the size of the cell do not have any influence on the structure of the cell.
On the basis of the function, there are different features that are added or modified in the cell.
For instance, the cells in the intestine are primarily involved in absorption and hence, they have a special structure called villi on their apical surface for maximal absorption.
Similarly, RBCs have a disc shape for maximum surface area for fulfilling its function of oxygen absorption and diffusion.

Over 1,800 mutations have been described within the CFTR gene. These mutations can be readily detected using PCR and DNA sequencing technologies. Prenatal genetic testing is available to identify 'carriers', and thus detect the risk of CFTR-related disorders. If a pregnant mother was tested and tested negative for any known disease-causing CFTR mutations, can it be assumed that the child born will be wild-type with respect to the CFTR phenotype? Explain.
a. No. If the father is a carrier and passes along a mutant allele to the child, the child will develop cystic fibrosis.
b. It depends on the genotype of the father.
c. Yes. Since this is a recessive disorder, even if the father is a carrier, the mother will contribute a wt allele, ensuring the child is wt.
Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.

What are the effects of fertilizers?A fertilizer is any material of natural or synthetic origin which is applied to the soil or to plant tissues for the supply of plant nutrients. Fertilizers may be distinct from that of liming materials or other types of non-nutrient soil amendments. Many sources of fertilizer which exist are both natural and industrially produced.
Fertilizers boost the crop yields, however the excessive usage of crops has hardened the soil, reduced fertility, also strengthened the insecticides, polluted air as well as the water quality, and emitted the greenhouse gases, creating health and environmental risks.
Therefore, the correct options are A and E.

A ball is dropped from the top of a building. The gravitational force is 10 N down, and the force of air resistance is 1 N up. What is the net force?
9 Nup
9 N down
11 Nup
11 N down
Answer:
9N down
Explanation:
The net force on the ball dropped has a magnitude of 9N and it is directed downward.
Given;
Gravitational force = 10N down
Air resistance = 1N up
Air resistance is an opposite force that acts against a body passing through air. It is a negative force.
Gravitational force is a force acting on a body due to gravitational attraction of the earth.
Net force = Gravitational force down - Air resistance up
= 10N - 1 N
= 9N down
The net force is 9N downward.

Predict what would happen to typical animal cells placed in 0.0M and 1.0M sucrose solutions, and explain your prediction. The animal cells molar concentration is 2.0M.
Answer:
The animal cell will take in water until it eventually swells or burst
Explanation:
Osmosis is an important phenomenon that drives the movement of water across membranes. It is defined as the movement of water molecules from a region of high water concentration/low solute concentration to a region of low water concentration/high solute concentration across a semi-permeable membrane.
In this case, the animal cell with a molar concentration of 2.0M is placed in 0.0M and 1.0M sucrose solutions. This means that the cell is placed in an hypotonic solution (solution with low solute concentration), hence, water will move from the extracellular solution into the animal cell since the solute concentration in the cell is more. The animal cell will begin to swell and eventually burst.
In hypotonic solutions, the concentration of solute is lower than the concentration inside the cell. If a cell (2M) is placed in two solutions (0M and 1M), water will move toward the cell interior, swelling it.
---------------------------------------
When talking about solutions, we can classify them as follows,
Hypertonic ⇒ A solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself.Isotonic ⇒ The concentration of solute turns to be the same inside the cell and outside.
Hypotonic ⇒ The concentration of solute in the solution is lower than the concentration inside the cell. The solute is more diluted in the solution than in the cell.
Water is considered to be a hypotonic solution.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Osmosis occurs when two dilutions of different concentrations -in this example, the interior of the cell and the solution- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute.
Hence, water can move from the most diluted side to the less diluted one.
Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.
As water enters the cell, the cell begins to enlarge and becomes bigger-sized.
Because isolated cells can not limit the amount of water moving in, it keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.
Under natural conditions, the body regulates the extracellular fluids to avoid cells swelling until they burst.
What we need to consider is
When a cell with a semipermeable membrane is placed in a hypotonic solution, water enters the cell. When a cell with a semipermeable membrane is placed in an isotonic solution, there is no water movement. When a cell with a semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.In simple words, in the proposed experiment, sucrose can not cross the membrane, but water can. So,
To solve this problem, we know that
The molar concentration in the interior of this animal cell is 2.0M.There are two cucrose solutions ⇒ 0M and 1.0 MIn both cases, the concentration in the interior of the cell is higher than the concentration in the solution.
In both cases the cell is in a hypotonic solution, meaning that water will get into the cell.
Water will move into the cell from the solutionBoth cells will swell as water moves in. The cell placed in a solution 1 M will reach equilibrium before the cell placed in a solution 0 M.---------------------------------------------------------
