Explanation:

In contrast to anaphase, where polymerization stops at kinetochores, metaphase sees flux-rate polymerization at kinetochores.

Then, kinetochores enter a condition where they are securely linked to the microtubule lattice (the "park" state), and flux pulls them poleward. Model 3 predicts that anaphase A and metaphase alignment are both influenced by kinetochore flux as well as motility. While sister separation at the beginning of anaphase enables kinetochores to convert to depolymerization and boost the rate of anaphase A to velocities larger than flux, flux biases the kinetochore into persistent polymerization during metaphase. Recent Drosophila investigations came to this result, but they were predicated on the unproven hypothesis that kinetochore microtubules flux at the same rate as nonkinetochore microtubules.

Correct Question:

Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X

A. has a lower amplitude.

B. has a shorter wavelength.

C. has a longer wavelength.

D. has a greater amplitude.

Answer:

C. has a longer wavelength.

The basic equation of frequency and speed are

velocity = frequency x wavelength

When both waves' velocities are the same then

v1 = v2

f-1 x wavelenght-1 = f-2 x wavelenght-2

Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

Answer:

C. become extinct

Explanation:

We become more likely to be extinct once the habitat is disrupted. So, C.Become Extinct would be the correct response. When no food or supplies are available, certain species won't have milk, ensuring that species starve and humans starve, end up becoming extinct!

Answer:

Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen

Explanation:

The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

ocean water evaporates and becomes water vapor, then when the droplets grow larger they fall as precipitation

Explanation:

hope this helps mark me please

When ocean water evaporates and turns into water vapor, bigger droplets that have formed fall as precipitation and the cycle is named as water cycle.

A cycle of events known as the "water cycle" includes precipitation in the form of rain and snow, drainage into streams and rivers, and return to the atmosphere through evaporation and transpiration. Water moves through this cycle between the earth's oceans, atmosphere, and land.

The water cycle demonstrates how water is constantly moving both inside the Earth and in the atmosphere.

It is a complicated system with a wide range of processes.

Liquid water evaporates to make water vapor, which subsequently condenses to form clouds and returns to earth as rain and snow.

The hydrologic cycle is crucial because it determines how water gets to people, plants, and other species.

Thus, when ocean water evaporates and turns into water vapor, bigger droplets that have formed fall as precipitation and the cycle is named as water cycle.

The condition that will most likely lead to more disruptive selection in the sparrow population is a change in the availability of seed sizes, where there is a decrease in the number of intermediate-sized seeds and an increase in the number of smaller and larger seeds.

Disruptive selection occurs when individuals with extreme traits are favored over those with intermediate traits. In this case, if there is a decrease in the availability of intermediate-sized seeds, sparrows with larger or smaller beaks will have an advantage over those with intermediate-sized beaks. Sparrows with larger beaks will be able to crack open larger seeds, while sparrows with smaller beaks will be able to handle smaller seeds more efficiently. This will lead to a divergence in beak size, with the intermediate-sized beaks being selected against.

Therefore, a change in the availability of seed sizes, where there is a decrease in the number of intermediate-sized seeds and an increase in the number of smaller and larger seeds, is most likely to lead to more disruptive selection in the sparrow population.

Explanation:

Chromosomes, which are made of DNA, contain genes. The genetic code that defines an organism's traits is found in DNA, a large, double-stranded molecule.

Long stretches of DNA are arranged into what are known as genes. The instructions for a particular attribute, like eye color or height, are encoded in each gene. Each creature has a unique number of chromosomes, which are located in the nucleus of a cell. In humans, there are 46 chromosomes in all, divided into 23 pairs. DNA and histone proteins, which help bundle the DNA and facilitate reading of the genes material, make up the chromosomes. The chromosomal structure is created by the tightly wound coils of DNA.

Explanation:

Levees may be man-made or natural. Sedimentation on the river bank raises the level of the surrounding land, creating a natural levee. In order to build an embankment for a man-made levee, workmen pile soil or concrete along the riverbanks (or parallel to any body of water that may rise).

Natural levee:

Natural levees are ridges created by overbank floods that leave sediments the size of sand and silt close to the river channel (Brierley et al., 1997). Natural levees are the highest topographic features in low-lying environments, making them ideal sites for both ancient and more modern population (Hudson, 2005).

Artificial levee:

In order to protect against flooding and minimise damage, artificial levees are frequently constructed over natural ones. They are often made of silt and can be strengthened with concrete, rock, or even plants. The Indus and Nile river basins, Mesopotamia, and China all have a long history of building artificial levees. Artificial levees result in increased water levels and velocities by restricting the river's flow (see Zong and Chen, 2000).

Answer:

A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. 

Answer:

A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.

The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.

Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.
