Marine sponges contain an enzyme that prevents the separation of chromatids during mitosis. Which stage of the cell cycle would be directly prevented by this enzyme
Answer:
The anaphase of the Mitotic phase
Explanation:
During the anaphase, the proteins (cohesins) that bind sister chromatids together are cleaved to produce two identical daughter chromosomes (meaning each chromosome contains the exact copy of the same genetic material). These identical chromosomes are then separated by a structure known as mitotic spindle. Individual mitotic spindle attaches itself to each chromosome which are then pulled to opposite poles/"sides" of the cell.
Thus, if an enzyme is going to prevent separation of chromatids during mitosis, the enzyme would do so at the beginning of this process, preventing the cleavage of cohesins which would prevent the separation of the chromatids and subsequently prevent this anaphase from occurring.

What should be done before measuring an unknown pH of a solution using a pH meter?
Before measuring the pH of an unknown sample, the pH meter should be calibrated by putting in the buffer solution, and then only it can show the correct result of the sample that needs to be tested.
What is pH?pH explains and shows the result of the hydrogen ion concentration in the solution; the higher the concentration of hydrogen ions, the lower the pH. This is called acid in nature. The lower the concentration of this ion, the more value it shows and the more likely it is to be considered a basic solution.
The neutral value is 7, while the range above it is classified as basic and the range below it as acid. The pH of an unknown sample can be determined by using pH paper or a pH meter, but the pH meter is more accurate for the sample. The PH meter is first calibrated and put in the buffer mixture to get accurate data. Then it is inserted into the target solution.
Hence, the pH meter should be calibrated by putting in the buffer solution, and then only can it show the correct result of the sample that needs to be tested.

dominant genes mask recessive genes are represented by lower xase letters are only inherited from the male parent are masked by recesive genes
Answer:
Dominant genes mask recessive genes.
Explanation:
Alleles are different variations of a gene. Every person has two alleles - one from each of their parents. Depending on whether it is expressed, an allele can be dominant or recessive.
A dominant allele is the one that is expressed even if the individual has one dominant and one recessive allele. This means that dominant alleles mask recessive alleles.
An example of a dominant allele is the one for brown eyes. This means that you need only one allele of this type to have brown eyes, which is why brown eyes are the most common.

How does the amount of greenhouse gases affect the temperature of the Earth’s Atmosphere?
Answer:
The more gas there is the more heat gets trapped in the atmosphere
Explanation:
as the heat increases it causes our polar caps to melt resulting in their mirror like white to fail at its natural duty, which is to reflect UV rays back out into space so that we don't overheat. It also causes other things to stop working naturally.

chewing that involves up/down, forward/backward, and side-to-side movements of the mandible is also known as Rotary chewing.
True or False?
Answer:
True
Explanation:
In the temporomandibular joint, there are two kinds of movements: rotation and translation.
Rotation is the movement around an axis. It is the movement of an object around its axes.
The mandibular rotation movement occurs in the condyles and might be produced in three planes: horizontal plane, frontal, and sagittal planes.
- Sagittal Plane: There are up/down, forward/backward movements involved.
- Horizontal Plane: These are lateral movements together with back and foward movements.
- Frontal: Involves up/down, and lateral movements.
how do chloroplasts get energy from the sun
Answer:
Your welcome
Explanation:
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Answer:
It will change shape and the substrate will no longer fit
Explanation:
if the enzymes that break down lipids were denatured, it will change shape and the substrate will no longer fit.
What are enzymes?Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Moreover, enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
Hence, enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced naturally in the body and help with important tasks, including: building muscle. destroying toxins.

At which location is the solar eclipse viewed in totality?
Answer:
2
Explanation:
It is at the center of the area that gets to most attention.
At location 2 the solar eclipse will be viewed in totality. Therefore, at this point, the solar eclipse will be clearly visible.
What is a solar eclipse?A solar eclipse is a natural phenomenon which occurs when the Moon moves in front of the Sun and blocks some of Earth's view of it, either completely or partially. A similar arrangement happens roughly every six months, during the new moon phase of eclipse season, when the Moon's orbital plane is closest to the Earth's orbital plane.
In the case given here, at point 2 the eclipse will be visible clearly as the moon is precisely aligned between the earth and the sun at that location due to which the eclipse is focussed at that point.Therefore, the correct location is 2.
