Centromeres of sister chromatids disjoin and chromatids separate. Which phase does this event happen?
Answers
Answer:
Anaphase
Explanation:
Cohesin is a protein that holds sisters chromatids together. Anaphase begins with the cleavage of that protein, enabling centromeres to split, and the movement of sister chromatides (new daughter chromosomes) toward the poles.
During the anaphase, microtubules that are not attached to chromosomes elongate and push apart. This elongation makes the cell longer and separates the poles.

Answers
Answer:
Coriolis effect
Explanation:
The rotation of the Earth is one of the climate modifiers. Considering the speed of the rotation, it is no wonder that it manages to influence the air masses and their movement in the lower atmosphere. Because of the rotation of the Earth, the air masses tend to swirl counterclockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. This process is causing lot of large cycles to occur on both hemispheres, and it is known by the term Coriolis effect.

The Chesapeake Bay is an important natural resource. Over the years, the number of oysters in the bay has declined dramatically, largely because of fishers who catch them and sell them as food. This has affected many other organisms that depend on oysters. This is an example of which type of short-term human-induced environmental change?
A.eutrophication
B.non-sustainable harvesting
C.nonnative species introduction
D.pollution
Answers
Answer: B. Non-sustainable harvesting.
Explanation:
Non-sustainable harvesting is a practice in which the resources are consumed in a way that not appreciable amount is left. This is a short term human induced environmental change. Such a change may last for a short period of time and the damge caused by the change will be recovered by the environmental conditions.
The oyster population which is being overexploited due to non-sustainable harvesting by fishing and depleted will recover in future with the few remaining members of the population. Hence, it is a short term human induce change.

Which of the following would most likely increase the rate of photosynthesis?
A. Changing a plant's light source to a lower brightness
B. Decrease the availability of water to the plant
C. Decreasing the temperature within the plant's environment
D. Exposing a plant to a higher light intensity
Answers
Answer:
D. Exposing a plant to a higher light intensity
Explanation:
Increase in light intensity serves to increase the rate of photosynthesis when other factors are present in adequate amount. It is due to the fact that the first phase of photosynthesis includes light dependents reactions that results in synthesis of ATP and NADPH in light dependent manner. These two products serve in dark phase of photosynthesis. Therefore, increase in light intensity increases the rate of photosynthesis.
Option D, exposing a plant to a higher light intensity, is most likely to increase the rate of photosynthesis as light provides the necessary energy for the photosynthesis reaction to occur. Other factors like water availability and temperature also influence photosynthesis but in this case, their decrease could potentially slow down the process.
Explanation:In terms of photosynthesis, the process through which green plants and some other organisms convert light energy, usually from the Sun, into chemical energy for their growth and survival, one of the key ingredients is light. The intensity of this light can greatly affect the rate of photosynthesis. So, among the options provided,
D. Exposing a plant to higher light intensity
is likely to increase the rate of photosynthesis. This is because light provides the energy required for the photosynthesis reaction to occur.
Conversely, decreasing light intensity (option A), decreasing the availability of water (option B), or lowering environmental temperature (option C) could potentially slow down the process. For instance, in low light conditions or shade, a seedling may not have enough light to promote sufficient photosynthesis. The rate of photosynthesis can also fall when water or optimal temperature levels are inadequate, as these conditions may lead to the closure of stomata, resulting in a constrained intake of carbon dioxide, a key reactant in photosynthesis.

Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. Slugs prefer to eat pink-flowering over white-flowering plants (due to chemical differences between the two), and plants experiencing severe herbivory are more likely to die. The bees that pollinate this plant also prefer pink to white flowers, so that Claytonia with pink flowers have greater relative fruit set than Claytonia with white flowers. A researcher observes that the percentage of different flower colors remains stable in the study population from year to year. Given no other information, if the researcher removes all slugs from the study population, what do you expect to happen to the distribution of flower colors in the population over time? 22.2
Answers
Answer:
Over time, the plants will eventually all be pink because bees are more likely to pollinate the pink plants meaning the white plants are less likely to survive
Explanation:
Without the predation pressure from slugs, the pink-flowered Claytonia virginica is likely to increase in frequency due to higher survival and reproductive success, as bees prefer and more effectively pollinate these flowers.
If the researcher removes all slugs from the study population of Claytonia virginica, a woodland spring herb, we can expect the distribution of flower colors to change over time. Since slugs prefer to eat pink-flowering plants, their removal would likely reduce the herbivory pressure on these plants. Given that bees prefer pink flowers and that pink flowers have a higher relative fruit set, in the absence of slug predation, pink-flowering individuals would potentially have higher survival and reproductive success compared to white-flowering individuals. This would lead to an increase in the frequency of pink-flowered plants in the population over time.
What type of cells tend to be damaged the most during chemotherapy and radiation treatments?
a. collagen and fibrous tissue
b. epithelial cells
c. nerve tissue
d. skeletal muscle cells?
Answers
c
you can notice that from many cases
Epithelial cells are the type of cells that are most prone to damage during chemotherapy and radiation treatments. This is due to their fast dividing nature, similar to cancer cells. While these treatments can harm healthy cells, they usually recover over time.
Explanation:The type of cells that tend to be damaged the most during chemotherapy and radiation treatments are b. epithelial cells.
Epithelial cells are the cells that line the surfaces of organs and structures throughout the body. They divide and replicate quickly, just like cancer cells. It is for this reason that they are more prone to be affected by chemotherapy and radiation therapies, as these treatments target fast-dividing cells.
Note that while chemotherapy and radiation therapies are effective in killing cancer cells, they also harm healthy cells, leading to side effects. However, healthy cells usually can recover from this damage over time.

Which of these diagrams best shows Kepler's model of the solar system?
Answers
Hi.
I believe the diagram that best shows Kepler's model of the solar system is the picture B, the sun is the center while the earth (and other planets) orbit in an equantless pattern
Answer:
Option D
Explanation:
According to the Kepler, the arrangement of solar system is heliocentric which means that the sun is at the centre and all other planet rotate around it.
As per Kepler’s first law - All the planet rotate around the sun in elliptical paths
As per Kepler’s second law - The radius vector wrt position of planet on elliptical orbit sweeps equal area.
As per Kepler’s third law - The cubes of the planets mean distances from the Sun is directly proportional squares of the sidereal periods
As per Kepler , the solar system arrangement would look like a way more similar to as shown in the option D
The nonfunctional pelvis and hind limbs found in some snakes support which statement about evolution?
a) Snakes began to evolve these structures, but selection pressures did not favor them.
b) Mutations tend to make species evolve to resemble other species in their environment.
c) Snakes evolved from the same common ancestor as species in which these structures are functional.
d) Selection pressures promoting snake evolution ceased before snake anatomy was well adapted.
Answers
Answer:
The answer is C. Snakes evolved from the same common ancestor as species in which these structures are functional.
Explanation:
The organs which apparently have no functional role in an organism but thought to be functional in past are called Vestigial Organs. One common example is the non functional Pelvis and hind Limbs in snakes. It is thought that snakes have evolved from reptiles. From fossil record it was predicted that many snakes like species were present in past and they had the pelvic bones while due to adaptation to the changing environment they lost the functional bones and evolved as snakes.

A population of rodents, called population A, lived together in harmony on a large landmass until one group of the population dispersed to a nearby island. Two million years later, the island population is split into two smaller, equal-sized populations when a river formed across the middle of the island. Now two new species have evolved on the island, A1 and A2. They have replaced the population from which they were derived. Which represents the phylogeny of the three extant species discussed in this scenario?
Answers
Answer:
Diagram K is the answer
Final answer:
The three extant rodent species, originating from population A, underwent allopatric speciation leading to species A1 and A2. This occurred due to habitat isolation and selective pressures. The phylogeny would show a divergence first between the mainland and island populations, then another split between A1 and A2 after a river separated them.
Explanation:
In the given scenario, allopatric speciation has occurred within a population of rodents, known as population A, leading to the evolution of two new species, A1 and A2. Initially, part of population A dispersed to a nearby island, separating them from the mainland population. Due to habitat isolation, the island population ceased reproduction with the mainland population and began to independently evolve. After two million years and the introduction of a river splitting the island habitat, the island population divided into two, preventing gene flow between the two groups.
This geographical separation instigated further allopatric speciation, resulting in the formation of two distinct species, A1 and A2. The phylogeny of these rodent populations would reflect their shared ancestry and subsequent divergences. Initially, population A from the mainland would be at the base of the phylogenetic tree. The branch then separates into the island population, which later bifurcates into two distinct branches representing species A1 and A2 after the formation of the river.
The result of the following cross indicates the orange eyes are _____ black eyes.
Answers
the answer is recessive to.
The orange eyes in the fruit fly cross are recessive to black eyes. A cross between a white-eyed male and a heterozygous red-eyed female results in a 1:1 ratio of red to white-eyed offspring for both sexes.
Explanation:The result of the cross indicates that orange eyes are recessive to black eyes. In Drosophila (fruit flies), eye color is often used as an example of a sex-linked trait. In a cross between a homozygous red-eyed female fruit fly and a white-eyed male fruit fly, the expected outcome for the F1 generation would be all red-eyed offspring since red is dominant over white.
However, a cross between a white-eyed male (XY) and a female heterozygous for red eye color (XwXw) would result in different phenotypes for the different sexes: 50% of the female offspring would be heterozygous with red eyes, 50% of the female offspring would be homozygous with white eyes, 50% of the male offspring would have red eyes (hemizygous dominant), and 50% would have white eyes (hemizygous recessive), giving a 1:1 ratio of red to white eyes for both sexes.
What type of symmetry did your starfish have
Answers
Answer:
An adult starfish has radial symmetry
Explanation:
The starfish (and all echinoderms) start out with bilateral symmetry (which is like humans who have 2 symmetrical halves) during their larval stage. However, during metamorphosis they lose this bilateral symmetry and develop some kind of radial symmetry (5 identical parts).
most starfish have pentaradial symmetry, which means that they have five arms that radiate out from a central disk.
How do we explain?pentaradial symmetry is a type of symmetry is common in echinoderms, which are a group of animals that includes starfish, sea urchins, and sea cucumbers.
There are a few exceptions to this rule. For example, some starfish have six arms, and others have even more. There are also some starfish that have lost their arms altogether. However, pentaradial symmetry is the most common type of symmetry in starfish.
