The process of nuclear division which creates two new identical nuclei is called

Answers

the answer is mitosis, where the nucleus divides into two identical nuclei

Answer:

Mitose

Explanation:

Mitosis is a type of cell division that occurs in all eukaryotic cells and ensures the formation of two daughter cells with identified nuclei. It is an important process for the growth and regeneration of multicellular organisms and for asexual reproduction of unicellular organisms.

Despite being a continuous process, mitosis can be divided into four distinct phases: prophase, metaphase, anaphase and telophase. This process begins after the interphase period, which comprises the time between two phases of cell division.

Answer: an FfxFf cross would produce- FF Ff Ff ff. Genotype: 1:2:1 (just look at the number of different pairs- 1 FF, 2 Ff's, and 1 ff.) Phenotype: 3:1 (because all the pairs with a capital F will appear, the only one that will not be expressed is ff, and there are FF, Ff, Ff which all have capital "F". so its 3:1.)

Some organisms that normally live in pond water contain water pumps. These pumps continually pump water out of the cell. Describe a scenario that might reverse the action of the pump.

Answers

In order to reverse the action of the pump we will have to stop the pumping of the water out of the cell. We need to clog the pump so it can no longer pump out water. This will force the water to go back into the cell slowly but surely and reverse its course.
Final answer:

A scenario that might reverse the action of a water pump in an organism living in pond water is placing it in a hypertonic environment, where water would move out of the cell by osmosis instead of into it.

Explanation:

Organisms that live in a hypotonic environment, such as freshwater, have adaptations to prevent their cells from taking in too much water by osmosis. One such adaptation is the presence of a contractile vacuole. In a scenario that might reverse the action of the pump, the organism could be placed in a hypertonic environment, such as a solution with a higher solute concentration than its cytoplasm. In this case, water would move out of the cell by osmosis instead of into it, and the pump would not need to expel excess water.

Antimicrobial x targets a specific protein in the cytoplasm of the bacterial cell, causing the bacteria to stop growing, but does not kill them. a few bacteria start to grow in the presence of antibiotic x. analysis of the bacteria that can now grow shows that they have changed the shape of the target for antimicrobial x. what conclusion can be made?

Answers

The answer to this question would be: Antimicrobial X is less effective against the new shape of its target.

In this question, the antimicrobial X targets a specific protein in the cytoplasm of the bacterial cell and the bacteria have changed the shape of the target for antimicrobial x. The changed shape of the antimicrobial X will cause it to stop working as it can bind to the specific protein in the bacteria cell anymore. 
Because some of the drug(that the shape changed) is losing its function, the effect of antimicrobial X will be reduced.

Final answer:

The bacteria that can grow in the presence of Antimicrobial X, despite its action, indicate the development of antimicrobial resistance through structural changes in the drug's target, highlighting evolutionary adaptation under selective pressure.

Explanation:

The conclusion that can be made from the scenario where Antimicrobial X targets a specific protein in the cytoplasm of the bacterial cell, causing the bacteria to stop growing but not killing them, and a few bacteria start to grow in presence of the antibiotic by changing the shape of the target, is that these bacteria have developed a form of antimicrobial resistance. This resistance occurs through a structural change in the target protein, which prevents the antimicrobial from binding effectively. Such a mutation allows these bacteria to survive and reproduce in the presence of the antimicrobial, a concept known as selective pressure. It is a clear example of how bacterial populations can evolve resistance to specific antibiotics or antimicrobials through genetic changes that alter drug targets.

Clouds that form over water are usually more efficient in producing precipitation than clouds that form over land. why?

Answers

Final answer:

Clouds over water are more efficient in producing precipitation as the oceans provide abundant water vapor from evaporation, and warmer oceanic air holds more moisture leading to heavier precipitation.

Explanation:

Clouds that form over water are usually more efficient in producing precipitation than clouds that form over land because the ocean supplies a greater amount of water vapor due to evaporation. This is because water evaporates from the surface of the oceans, leaving behind salts, and as the vapor rises, it cools and condenses into clouds which can result in various forms of precipitation like rain, snow, hail, and sleet. Furthermore, the air over the ocean is often warmer and can hold more moisture, leading to more significant cloud formation and precipitation potential.

The water cycle is underpinned by the Sun's energy, which warms the oceans and causes water to evaporate, contributing to this effect. Condensation of this water vapor within clouds releases heat into the atmosphere, potentially causing air to rise and clouds to grow, which can also contribute to the formation of stronger storms and larger amounts of precipitation.

Which structures are found in plant cells, but not in animal cells

Answers

Final answer:

Plant cells have a cellulose cell wall, chloroplasts for photosynthesis, and a large central vacuole for storage and pressure maintenance, which are not found in animal cells. Both have common cellular structures like a plasma membrane, cytoplasm, and nuclei.

Explanation:

Specific cellular structures found in plant cells but not in animal cells include the cell wall, chloroplasts, and a large central vacuole. The cell wall, primarily made of cellulose, provides the cell with structural support and protection. Chloroplasts enable the process of photosynthesis, the conversion of light energy into usable sugars. The large central vacuole serves multiple functions such as storage and maintaining turgor pressure within the cell. Unlike plant cells, animal cells do not have these structures. Both types of cells share other cellular components such as a plasma membrane, cytoplasm, and nuclei.

What can you conclude by comparing the left and right hydrographs, each of which depict the same amount of time?

Answers

Hydrography are gentle and sweet

The peak discharge is greater on the left, both graphs fail to depict a real deluge. A speedier occurrence, like a flash flood, is depicted in the right diagram.

What are left and right hydrographs?

Due to friction, stream velocity is highest in the middle of the stream, close to the surface, and is lowest along the stream bed and banks, The discharge rises fast and falls off gradually.

Stage and streamflow may be shown on a hydrograph graphic or even both. The visual display of water level data and forecasts on a single graphic is made possible by the use of hydrographs.

Therefore, read a hydrograph, choose a rough date, and follow a vertical line up to the point when it crosses the graph. You may get the stream discharge on that date by reading horizontally to the left.

A tobacco plant is heterozygous for the genes for long stems (Ss), large leaves (Ll), and fibrous roots (Rr). It is crossed with another tobacco plant with genotype ss ll rr. How many of the 80 offspring of this mating will be heterozygous for all three genes? These genes are not linked. Hint: create three separate Punnett squares and use the product rule (section 10.4C).

Answers

Firstly, you may start by doing the Punnett squares as suggested, one per each characteristic. Attached is the three Punnet squares, made by me, as they should look in the end.

For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.

[tex] \frac{1}{2} [/tex]Ss×[tex] \frac{1}{2} [/tex]Ll×[tex] \frac{1}{2} [/tex]Rr=[tex] \frac{1}{8} [/tex]SsLlRr

Total offspring×[tex] \frac{1}{8} [/tex]=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.
