What is a limitation of this diagram? (1 point) It does not show that mitosis creates more than two daughter cells. It does not show all phases of mitosis. It does not show senescence. It does not show the final result of mitosis.
Answers
Since the diagram is about cell division and is indicating with an arrow that the cell has gone through the interphase and mitosis events, its limitation is that it does not show all phases of mitosis. Option B.
---------------------------
The diagram is about cell division through the process of mitosis.
It shows a cell, its nucleus, and chromosomes.The arrow indicates that the cell has gone through the S phase and then through mitosis.Finally, it shows the two daughter cells.Let us first review the stages involved in cell division. After that, we will answer the question.
INTERPHASE
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage. During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
MITOSIS
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Mitosis occurs in four stages.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles. In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.CYTOKINESIS
Finally, cytokinesis occurs. It occurs immediately after mitosis, and refers to the cytoplasmic division.
Options:
A) It does not show that mitosis creates more than two daughter cells.This is not correct because a single mitosis event produces only two daughter cells. Succesive mitosis can produce many new cells. But each cell can only divide into two.
B) It does not show all phases of mitosis.This is correct. The diagram only says that mitosis has occurred, but it does not represent all the phases.
C) It does not show senescence.The diagram does not show senescence, but porbably because it is not involved in cell division. So this optionn would not be correct either.
D) It does not show the final result of mitosis.This is wrong because it is showing that there are two new daughter cells, which are equal to the original cell.
So the only correct option is B

Raj takes a meteorology class and learns about the effects of air density on the weather. What affects the density of air? Explain.
Answers
Warm air is less dense and will rise/become buoyant
Higher elevations above sea level the air is less dense. Running at high altitudes requires more deep breathes to get same oxygen content into lungs.
Higher humidity (temp. And pressure held constant) is less dense. Water molecules weigh less than nitrogen and oxygen molecules. To get more moisture into same volume of air requires displacement of some of the heavier nitrogen and oxygen.
Answer:
Temperature, pressure, and moisture/humidity are all factors to consider.
Warm air has a lower density and rises/becomes buoyant.
The air is less dense at higher elevations above sea level. To bring the same amount of oxygen into the lungs when running at high altitudes, you'll need to take more deep breaths.
Humidity is less dense at higher temperatures and pressures. The weight of water molecules is less than that of nitrogen and oxygen molecules. To get more moisture into the same volume of air, some of the heavier nitrogen and oxygen must be displaced.

if a snake species were introduced to an ecosystem where it had no natural predators, what long-term effect do you predict the snakes would have on the population dynamics of the ecosystem?
They would breed with native snake species, resulting in an increase in biodiversity in the ecosystem.
They would serve as a food source for predators of native snakes, causing an increase in native snake populations.
They would form mutualistic relationships with native snakes, since they would occupy the same niche in the ecosystem.
They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction.

Answer:
D. They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction.
Explanation:
Just took the test! :D
They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction. Hence option D is correct.
What are predators?Predators are living things that go after and kill prey. Both carnivores and omnivores can be predators. Predation can be classified into four categories: carnivory, herbivory, parasitism, and mutualism. Depending on whether or not the victim dies, each sort of predation can be classified.
Predators include weasels, hawks, wolves, mountain lions, and grizzly bears. Because they are carnivores, predators only eat meat.
If a snake species were introduced to an ecosystem where it had no natural predators, it would compete with native snakes. Hence, option D is correct.

Sharks and whales are a classic example of two different animals revealing
similar traits in the same environment. One of the similarities of these two
marine animals is their habitat. They both live in the vast range of depth in
their environment. They also have the same fin structure. They only have a
single tail for propulsion and because they are both large aquatic animals,
they both consume large volume of food, however, sharks hunt for their
food. Whales do not have this hunting tendency. Another difference of
sharks to whales is their class. Whales are mammals while sharks are fish
but they both live in the ocean. Also, whales have bones while sharks only
have cartilages.
Answers
Answer: The similarities between shark and whales are indicative of convergent evolution.
Explanation:
Convergent evolution can be defined as the process in which the organisms are not closely related but they evolve similar traits as a result of living in a similar kind of environment or adapting traits which enable them to perform the same ecological niches.
The similarities between shark and whale is indicative of convergent evolution as the animals are not related to each other phylogenetically but they live in the same environment this they evolve same kind of traits.
The similarities between sharks and whales represent an example of convergent evolution.
Convergent evolution refers to the evolution of similar phenotypic traits in unrelated and/or distantly related species.Convergent evolution creates analogies, i.e., different structures that may have the same function but were not present in the last common ancestor of both species. On the other hand, divergent evolution refers to the development of dissimilar phenotypic traits in closely related species as a result of evolution by natural selection, thereby leading to speciation.In convergent evolution, similar phenotypic features (traits) have evolved independently and repeatedly in each lineage in order to adapt to particular environmental conditions.In conclusion, sharks and whales are an example of convergent evolution because they are distantly related species that exhibit similar phenotypic features in the same environment.

What feature of double-stranded dna makes it necessary to have a leading strand and a lagging strand during replication?.
Answers
Answer:
there must be a pre-existing chain of nucleotides
Explanation:
So RNA primers are used for initiation of new DNA chains.
RNA primer is short piece of RNA, synthesised at the end of the new strand with the help of DNA specific RNA polymerase enzyme called primase and primers provide free -OH for DNA polymerase to start polymersing. leading template strand requires primer only ones. But lagging template strand requires many primers. Once primer is ready DNA Pol(III) will come & start adding deoxyribonucleotide to the -OH of primer by complementary basepairing. Two nucleotides link each other by phosphodiester bond. The daughter DNA for template is synthesised continuously, Therefore called leading strand. DNA polymeraseIII has Exonuclease activityIt can add nucleotides in the direction. Replication is discontinuous on the other template with polarity because only a short segment of DNA strand can be built in direction due to exposure of a small stretch of template at one time.
