Answers

Answer 1

Answer:

Regeneration.

Explanation:

Planarian can be cut into pieces, and each piece can regenerate into a complete organism. Cells at the location of the wound site proliferate to form a blastema that will differentiate into new tissues and regenerate the missing parts of the piece of the cut planaria.

Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: increased osmotic pressure in the filtrate that draws plasma through the membrane decreased osmotic pressure in the filtrate that increases the amount of filtration increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration neutral change in osmotic pressure with no effect on filtration

Answers

Answer:

The correct answer is ''increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration.''

Explanation:

Osmotic pressure is understood to be the force that must be applied to a solution when the flow of solvent needs to be stopped by means of a membrane with semi-permeable characteristics.Colloidal osmotic pressure in glomerular capillaries: it is the pressure exerted by proteins in the blood, which tends to recover the filtered water. To generate and maintain glomerular filtration, filtration pressure is required. That is, glomerular filtration is a physical phenomenon regulated by hemodynamic changes that affect the glomerulus and, although it is the initial excretion mechanism, it is not the exclusive regulator. Water, ions and some nutrients are mainly reabsorbed in the proximal tubule by different mechanisms. The water will follow a passive transport process by osmotic drag. The activity of the tubule is highly dependent on maintaining a fluid osmotic pressure similar to that of plasma. Since proteins and other elements that participate in the maintenance of the plasma osmotic pressure do not cross the glomerular barrier, in the tubule, the isoosmotic pressure with the plasma is fundamentally conditioned by the content of water and salt (dissociated as chlorine and Na +) of the ultrafiltered.

Cells and transport proteins are physically prevented from passing through the filtration membrane for this the correct answer is to increase osmotic pressure in the glomerular capillaries that reducing the amount of filtration.

Osmotic strain is known to be the pressure that needs to be carried out to an answer whilst the glide of solvent wishes to be stopped with the aid of a membrane with semi-permeable characteristics.Colloidal osmotic strain in glomerular capillaries: it's far the strain exerted with the aid of using proteins withinside the blood, which has a tendency to get better the filtered water. To generate and keep glomerular filtration, a filtration strain is required.

What is glomerular filtration?

That is, glomerular filtration is a bodily phenomenon regulated with the aid of using hemodynamic modifications that have an effect on the glomerulus and, even though it is the preliminary excretion mechanism, it isn't the different regulator.

Thus it is clear that the above answers are well explained.

B. Bacterial populations in hospitals develop resistance to drugs used to combat infection by them.

C. Scientists breed cows that give greater amounts of milk than their ancestors.

D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.

Answers

Answer:

The correct answer would be - C. Scientists breed cows that give greater amounts of milk than their ancestors

Explanation:

Natural selection is the process of adapting according to the new changes in condition and change accordingly to survive. So the individuals of organisms that are better and adapt faster to survive and reproduce better than others are the result of natural selection.

Plants developed thorns so they can be avoided by predators is the adaption and example of natural selection. Similarly, bacterial populations adapt and develop resistance to the drug. Fruit fly larva developed and adapt as well. Breeding cows for more amount of milk than ancestors by scientists is not natural selection.

Read the excerpt from How Hurricanes Form.

Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.

Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.

The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure. The higher pressure above the hurricane continually flows down into the eye.

a
Hurricanes are often compared to engines.

b

4. In transcription, how come the whole DNA molecule is not copied into mRNA?

Answers

Answer:

Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors.

Explanation:

DNA is transcribed into mRNA and this mRNA has the complementary sequence of DNA but is not identical to DNA.

What is transcription?

The mechanism for transferring genetic information becomes more complicated if both strands of DNA serve as transcriptional templates.

If both strands of DNA serve as transcriptional templates, dsRNA would be produced, preventing the synthesis of proteins.

Because its sequence is complementary to the DNA template, the mRNA is not an exact replica of the DNA segment even though it includes the same information.

Therefore due to complementary not identical sequences of mRNA during transcription whole DNA molecule is not copied to mRNA.

Why is the structure of a
nucleosome so important?

Answers

Answer:

In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression  

Explanation:

In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.

A canyon is a small, deep valley with cliff-like sides. The Spanish word caon, which meaning “tube” or “pipe,” is where the term “canyon” originates. Thus, option A is correct.

What Canyons type of land features represented?

A deep valley that has been carved into the surface of the earth over a long period of time by erosion from a flowing river is referred to as a canyon.

It is also referred to as a gorge and typically features rocky cliffs and very steep walls. One of the most well-known instances is the Grand Canyon, which the Colorado River carved out.

Canyon: A deep valley with steep walls and a V-shape created by a river slicing through hard rock. These valleys are common in the upper reaches of rivers, where the stream's fast, strong current rapidly digs the valley. Gorges are smaller valleys with a similar aspect.

Therefore, Although “gorge” is frequently used interchangeably with “canyon,” a gorge is nearly invariably narrower and steeper.

why is there minimal seismic and volcanic activity in New York

Answers

NY1 does state that New York is not close to a tectonic plate, and it is uncertain which one of these faults—if any—would be the source of a strong earthquake.

Answer:

Explanation:

lthough the eastern United States is not as seismically active as regions near plate boundaries, large and damaging earthquakes do occur there. Furthermore, when these rare eastern U.S. earthquakes occur, the areas affected by them are much larger than for western U.S. earthquakes of the same magnitude.[1] Thus, earthquakes represent at least a moderate hazard to East Coast cities, including New York City and adjacent areas of very high population density.

Seismicity is scattered throughout most of the New York metropolitan area, with some hint of a concentration of earthquakes in the area surrounding Manhattan Island. The largest known earthquake in this region occurred in 1884 and had a magnitude of approximately 5. For this earthquake, observations of fallen bricks and cracked plaster were reported from eastern Pennsylvania to central Connecticut, and the maximum intensity reported was at two sites in western Long Island (Jamaica, New York and Amityville, New York). Two other earthquakes of approximately magnitude 5 occurred in this region in 1737 and 1783.[2][3][4]

The map shows earthquakes of magnitude 3 and greater that occurred in this region from 1924 to 2010, along with locations of the larger earthquakes that occurred in 1737, 1783 and 1884. More recently, the 2011 Virginia earthquake, a 5.8 magnitude quake centered in northern Virginia that occurred on August 23, 2011, was felt by the occupants of some buildings in Manhattan, more than 200 miles north of the quake's epicenter and caused minor physical building damage in Brooklyn.[5] There were some disruptions, including building evacuations and delays at airports, while Amtrak train service at Penn Station was also delayed.[6]

Charli thinks she does better on tests after she has had coffee in the morning. One morning she drinks a cup of Folger's coffee and then does very well (A-) on her chemistry test. She does it again before her next chemistry test and again does very well (B+). Now she is convinced her hypothesis is right?

Answers

Answer:

Her hypothesis is right.

Explanation:

The Charli's hypothesis is right because caffeine present in coffee helps in boosting of memory if consume it in a normal range. Recent research indicates that caffeine may enhance long-term memory of an individual. When the memory is boost so the individual has the ability to memorize more knowledge that leads to good performance in the examination so the caffeine present in the coffee helps Charli to give good results in the test and we can say that her hypothesis is right.
