Which of the following is NOT an example of natural selection?
A. Plants with thorns are less likely to be eaten by herbivores than other members of the same species that lack thorns.
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.
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.
Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body. The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?
Answer:
please give me brainlist and follow
Explanation:
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.

标题:
Arrange their 3 homologous pairs into Metaphase 1 (this will represent tetrads)
3. How many chromatids do you have?
RUBE
Answer:
Six pairs of chromatids.
Explanation:
There are six chromatids pair present if there are 3 homologous pairs of chromosomes because in each chromosome two chromatids are present. A chromatid refers to two identical halves of a replicated chromosome. Each chromatid has two arm like structure called telomere and these two chromatids are attached to one another from a point called centromere. So we can conclude that three pairs chromosomes have six pairs of chromatids.
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
The eye of the storm is the calmest part of the storm and has very low air pressure.
c

Explanation:
Why is the structure of a
nucleosome so important?
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.

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?
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.

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
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]
