If pharmaceutical researchers want to learn how to keep cancer cells from dividing uncontrollably, which
approach are they most likely to try?

Interrupt some stage of the cell cycle, such as the formation of the spindle that separates chromatids.

Develop strong dyes that will be able to color the chromosomes for good visualization.

Provide dangerous levels of radiation to irradiate the
cancer cells in a human being.

Starve the cancer cells by starving the patients, thereby reducing chances of cell division.

Answers

Answer 1

Answer:

c

Explanation:

Answer 2

Chemotherapy i.e. use of drugs to destroy the cancer cells by inhibiting their growth and division. Therefore, option (A) of interrupting stages in cell cycle is correct.

What do you  understand by chemotherapy?

Chemotherapy is a medication that employs strong chemicals to destroy rapidly developing cells in your body. Chemotherapy is most commonly used to treat cancer because cancer cells grow and proliferate significantly faster than the rest of the body's cells. There are several chemotherapy medicines available.

Taxol (Paclitaxel) and other drugs that poison microtubules and impede the mitotic spindle have been used extremely efficiently in chemotherapy. This prevents cancer cells from proliferating and kills them.

Therefore, pharmaceutical researchers uses drugs to learn cancer treatment. Option (A) is correct.

A. Osmolarity
B. Equilibrium
C. Homeostasis
D. Tonicty

Answers

I believe the answer is
D) Tonicity

The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.

What is osmolarity of a solution?

Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.

According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.

Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.

From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.

Therefore, osmolarity  measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane.

1) A class collected water samples from a nearby pond and wants to observe the samples for
microorganisms. Which microscope would be the most appropriate for the students to use?
A. Dissecting microscope
B. Compound light microscope
I
C. Transmission electron microscope
D. Scanning electron microscope

Answers

Answer:

Compound light microscope

Explanation:

This is the ideal microscope because it requires the passage of  harmless beam of light through the specimen.Since the pond contain living creatures this is best to use.

C and D both require the transmission of beam of electrons through a sample. D depends on the reflection of the electron  after scanning the specimen surfaces and sent this to the lenses of the observer.(C)involved the  passing of the beam of electrons through the specimen the interaction of the electrons with the atoms in the specimen(,therefore in both cases  these specimens can not be wet and living.

The specimen should be dry in both cases and therefore non -living ,because the chamber for the specimen must be a vacuum,and living organism can not survive in the vacuum. Thus pond water can not be used as specimen because the specimen in the water but me be living.

It takes just four hours for one bacterium to become _____.

Answers

Answer: 256 bacterium.

Explanation:

suppose a bacterium would divide once in every half an hour, this means it would be double in half an hour.

therefore, a number of the bacterium after half an hour will be 1 x 2 = 2.

After one hour, we would have doubled the number of bacterium =2 x 2

= 4.

Also, in one and a half hours, it would become 4 x 2

= 8.

In 2 hours, it would be 8 x 2 = 16.

Also in two and half hours, it would  be 16 x 2

= 32.

In three hours, it would be 32 x 2

= 64.

In three and a half hours, it would be 64 x 2

= 128.

Funally, in four hours, the number of bacterium would have been multiplied to 128 x 2

= 256.

It takes just four hours for one bacterium to become 256 bacteria.

It should be noted that a bacterium will divide once in every half an hour. This implies that it'll be double in every half hour. Therefore, for an hour, there'll be 2 bacterium.

Since it doubles every half hour, in 2 hours, the value will be 16 bacteria. Therefore, the value in four hours will simply be:

= 16 × 16 = 256 bacterium.

Therefore, it takes just four hours for one bacterium to become 256 bacteria.

Which statement describes a similarity between asexual reproduction and sexual reproduction? Both processes involve fertilization. Both processes involve cell division. Both processes produce genetically identical offspring. Both processes require two parents.

Answers

Answer:

The correct answer is B. Both processes involve cell division.

Explanation:

Both asexual and sexual reproduction involve cell division; they are means of creating offspring.

Only sexual reproduction involves fertilization, so we know that choice A is incorrect.  Only asexual reproduction produces genetically identical offspring, so choice C is also incorrect.  Finally, only sexual reproduction requires two parents, so choice D is not correct either.

This leaves us with choice B as the correct answer.

You did an experiment where you want to test if a special kind of fertilizer will actually help your apple tree produce a lot of apples. To do the experiment you went to your local nursery and purchased two of the same kind of apple trees. You planted both trees in your sunny backyard , gave both of them the same amount of waterbut you gave one tree the special fertilizer and the other tree with the regular old fertilizer you've used before . After about a month , you noticed that the tree that got the special fertilizer grew over 100 apples than the other tree that grew about 40 apples . From this experiment , which of the following is considered the dependent variable ?

Answers

Answer:

Dependent variable: number of apples

Explanation:

In an experiment, the independent variable is the variable that isn't modified by the other variables measured in the experiment. In the example above indicated, the independent variable is the fertilizer used in the experiment. On the other hand, the dependent variable is the variable tested or measured in the experiment, thereby this variable is 'dependent' of the independent variable.
