Answer:
1. The chromosomes arrive at the cell poles.
2. The mitotic spindle disassembles.
3. The vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes
4. Separate the nuclear DNA from the cytoplasm.
answer:
During telophase, the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle also breaks down, and new nuclear membranes (nuclear envelope) form.

After a robbery why should you move away from any place that a robber may have been
To prevent the crime scene from being tampered with and the evidence from being lost, we should leave any area where a robber may have been after a robbery.
After a robbery, what should you do?Immediately dial the police. Tell them right away if someone is hurt so they can send out the emergency services. Provide police with the robber's departure time, description, and mode of transportation. Till they give you the all-clear to end the call, hang in there.
Keep your eyes and ears out for anybody around. Know who is walking in front of you and behind you. People or cars that seem suspicious, people who are dressed improperly for the weather, and loiterers are all things to be on the lookout for.

A. Producers are used to put water into the air of
dry places.
B. Producers help transfer energy from
secondary to tertiary consumers.
C. Producers capture energy and convert it for all
organisms to use.
Answer:
C
Explanation:
Producers are also known as autotrophs, which they make their own food. Producers capture sunlight energy and use it to convert CO2 (carbon dioxide) and H2O (water) into O2 (oxygen) and C6H12O6 (glucose) for other organisms to use. This process is called photosynthesis.
What is photosynthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

What is it called when a species not native to an area species that invade the ecosystem and outcompete the native species causing the native species to decline potentially to extinction?
The phenomenon where a non-native species invades an ecosystem and outcompetes the native species causing the native species to decline potentially to extinction is called "invasive species.
It occurs when non-native species, also known as invasive species, establish themselves and thrive in an ecosystem, causing harm to the native species. Invasive species possess traits that give them a competitive advantage over the native species, such as rapid reproduction, efficient resource utilization, and resistance to local predators or diseases.
The consequences of biological invasions can be severe. The invasive species can outcompete native species for resources like food, habitat, and water, leading to a decline in native populations.
They may also directly predate upon or introduce diseases to native species, further exacerbating their decline. In some cases, the native species are pushed to the brink of extinction or even driven to extinction.
Biological invasions are a significant global concern due to their ecological, economic, and social impacts. They can disrupt ecosystem functioning, alter natural habitats, reduce biodiversity, and cause economic losses in industries like agriculture, forestry, and fisheries.
Efforts are made to prevent and control invasive species through monitoring, early detection, and management strategies such as eradication, containment, and control programs to mitigate their negative effects and protect native species and ecosystems.

16. What would happen if a cell divides before DNA replication is completed?a. Daughter cells would receive incomplete genetic information, but wouldregain lost information in the G. phase.b. Daughter cells would receive incomplete genetic information, but wouldregain lost information in the Sphase.c. Daughter cells would contain all genes of the parent cell, but would notfunction normally.d. Daughter cells would receive incomplete genetic information and neverregain it, and they may not survive.
To answer this question we need to remember quickly how a cell divides a cellular cycle, as we know the duplication of genetic material occurs in the S phase, meanwhile, the actual division of the cell occurs in the mitosis or meiosis (M phase), therefore if a cell divides before complete genetic duplication the are two possible scenarios, in the first, one cell receives the complete information and the other get incomplete information and is non-viable, the second is that both cells receive incomplete information, when genetic information is incomplete will never be recovered and in many cases the product is non-functional. Therefore we can say that the correct answer is option d.
To protect our rights, the Constitution divides powers between the federal government's branches. This principle is called "separation of powers." Each branch of government holds distinct but equal authority. For example, Congress has the power to create laws, while the president has the power to execute these laws. The preamble states the purpose of "securing the Blessings of Liberty." Our freedoms are secured when power is not concentrated in any single branch of government. This helps our government to provide for our needs while respecting our rights.
Answer:
Explanation below
Explanation:
Separation of powers is very important and crucial in federal type of government. This is helpful because it decentralized the power, and prevent one arm of government from being a dominating force.
It will help the government to provide the necessary and needed infrastructure for the citizens. This is because the conclusion will be reached with approval of all the arms of government.

(В) a cell with 24 chromosomes, but not genetically identical to the parent cell
a cell with 12 chromosomes, and one chromosome is donated from each
homologous pair of the parent cell
0 a cell with 12 chromosomes, and 6 homologous pairs of chromosomes are donated
from each parent cell
Answer:
a cell with 12 chromosomes, and one chromosome is donated from each
homologous pair of the parent cell
Explanation:
Meiosis is one of the two types of cell division that involves sexual reproduction. Meiosis is the division that involves the production of four daughter cells (gametes) with each having its chromosomal number reduced by half. Meiosis is called "reduction division" because it reduces the chromosome number of the parent cell.
In this question, a parent cell with 24 chromosomes is said to enter meiosis. This means that after the meiotic division, daughter cells with 12 chromosomes will be produced in such a way that one of each homologous pair of chromosome (chromosomes from male and female parent) is donated to each gamete.

The minerals in a marble statue react
with water to form acids and pores in
the structure.
A piece of rock crumbles after being
constantly thrashed by strong waves.
Industrial runoff forms cracks in a
rocky structure in its path.
The rocks in a region are streaked
orange after being exposed to
repeated rains.
The events described involve both mechanical and chemical weathering processes, highlighting the complex nature of how weathering affects geological structures.
The events can be identified as the result of mechanical weathering or chemical weathering as follows:
The minerals in a marble statue react with water to form acids and pores in the structure - This is an example of chemical weathering. The water reacts chemically with the minerals in the marble, causing them to dissolve and form acids. These acids further react with the marble, leading to the formation of pores and overall degradation of the statue's structure.
A piece of rock crumbles after being constantly thrashed by strong waves - This is an example of mechanical weathering. The constant thrashing of strong waves exerts physical force on the rock, causing it to break apart or crumble. This type of weathering occurs due to mechanical forces like abrasion, pressure, or impact that physically break down the rock into smaller pieces.
Industrial runoff forms cracks in a rocky structure in its path - This is a combination of chemical and mechanical weathering. The industrial runoff may contain acidic or corrosive substances that chemically react with the minerals in the rock, leading to their dissolution or weakening. The cracks in the rocky structure may also be a result of the mechanical force exerted by the flowing runoff, causing physical fractures in the rock.
The rocks in a region are streaked orange after being exposed to repeated rains - This is an example of chemical weathering. The repeated rains introduce water into the rocks, which may contain dissolved iron compounds. Over time, these iron compounds oxidize in the presence of water and oxygen, leading to the formation of orange-colored iron oxide minerals, such as rust. The streaking of rocks with orange indicates the chemical transformation of the minerals due to the weathering process.
In summary, the events described involve both mechanical and chemical weathering processes, highlighting the complex nature of how weathering affects geological structures. Mechanical weathering involves physical forces breaking down rocks, while chemical weathering involves chemical reactions leading to the alteration or dissolution of minerals.

How did the accurrences of the different traits change over the 30-year period? Use euidence from the graph to support your answer. Using what you know about natural selection and adaptation, what generalization can you make based on these changes?
When changes occur to face environmental pressures, they must increase the individual's fitness to be favored by natural selection and result in adaptation. Between 1950 and 1980, individuals with half their bodies covered by plates decreased, while individuals with their whole bodies covered by plates increased.
How are adaptation and natural selection related?
Adaptations can be understood as the way in which different organisms manage to improve their fitness in the environment in which they live. To do it, they must adjust to the changes and selective pressures acting on them.
Adaptations involve changes and are usually related to mutations (let us remember that mutations are changes in DNA nucleotide sequences).
These changes must be beneficial for the individuals, meaning they must increase their fitness and make them more competitive.
If they do not increase their fitness (aptitude) they get lost.
If they increase the individual's fitness, they are selected by natural selection and transmitted through generations.
When natural selection favors a mutation, it sets it in the population and is inherited by the following generations. These mutations improve the individual's survival and reproductive rates. Hence, natural selection results in adaptation.
Image explanation
In the exposed example, we can see how the percentage of plates covering the animal's body changed through time.
At the beginning of the study (the year 1950), most animals had half of their bodies covered by plates (green bar), and only a few individuals had 2/3 bodies protected (orange bar).
As the lake changed its clarity, stickleback fishes with only half of their bodies protected got probably more exposed and easily seen by their predators. Their survival and reproductive rates decreased. From 1950 to the end of the study, their population size decreased significantly.
Predation acted as the environmental pressure. So the fish species needed to face this problem.
By 1960, a few individuals developed a new strategy. Their whole bodies were protected by plates (blue bar). This phenotype meant an increase in their survival and reproductive rates, so this strategy spread more in the population. Natural selection favored this change and set it.
By 1980 most individuals had their whole bodies protected by plates, and only a few of them still had half of their bodies covered. Since this turned out to be a beneficial change, population size started to recover.

Every year thousands of people in the UK have heart attacks.
A heart attack is caused when the heart muscle cells do not get enough oxygen, causing the cells to die.
Statins and stents are two treatments used to reduce the risk of someone having a heart attack.
Evaluate the use of statins compared with the use of a stent to reduce the risk of a heart attack. [6 marks]
Statins lower cholesterol and prevent plaque buildup, while stents restore blood flow. Statins are preventive, stents are reactive; both reduce heart attack risk (option b).
Statins are medications that help reduce cholesterol levels and prevent plaque buildup in the arteries, thus decreasing the risk of heart attacks.
They are typically used as a preventive measure for individuals with high cholesterol or existing heart issues. Stents, on the other hand, are small mesh tubes inserted into narrowed or blocked arteries to restore blood flow.
They are a reactive treatment, used after detecting significant artery blockage or following a heart attack.
Both statins and stents have their own advantages in reducing heart attack risk, with statins acting as a preventive measure and stents providing immediate relief to blocked arteries.
