What is the relationship between mitosis and the cell cycle?
Brainliest if correct
Mitosis represents only about 10% of the cell cycle.
The cell cycle represents about 90% of mitosis.
DNA synthesis takes place during mitosis; the cell divides in two during the cell cycle.
The parent cell is created during mitosis; the daughter cells are a result of the cell cycle.
Answer:
The cell cycle represents about 90% of mitosis.
Explanation:
The cell starts the process resulting in division. The entire cell cycle may be considered to be in four phases; G1, S, G2, and M. In the G1 phase, the cell doubles in size, and there is formation of new organelles and materials required for two cells. During this phase, there is nucleus migration to the center of the cell. This phase ends with the G1/S checkpoint. The process can be terminated at this point, or proceed to S phase in which DNA and associated nuclear proteins are replicated. By the end of the S phase, the cell contains two entire copies of its genetic information. The cell proceeds to G2 phase where the chromosome starts condensing, and structures required for division are formed. A discrete band of microtubules forms around the cytoplasm marking the plane of cell division. At the end of the G2 phase, the cell undergoes another checkpoint: G2/M checkpoint, upon which, if conditions are appropriate, the cell enters M phase in which it divides.
Describes the interactions that occur among systems are perform the functions of transportation response and reproduction in plants
Transportation system is maintained by xylem and phloem, response is maintained by endocrine system, and sexual reproduction is maintained by flowers and seeds.
Explanation:All the systems in plants are very well collaborated with each other, and the response between each one of them results in effecting other systems. The transportation system of plants consists of xylem and phloem. This tissues grow and flourish due to endocrine system. The auxin, cytokinin, and the gibberellin has direct effects on the growth of the plant tissues.
Now the plant reproduction i.e flowering and seed formation are also dependent on the endocrine system. Auxin is responsible for bud formation. So each and every system is dependent on each other for their flourishing.
Final answer:
The interconnected systems of plant transport, response, and reproduction are integral for plant functionality. The vascular system, including xylem and phloem, is crucial for distributing water and nutrients, while the shoot and root systems play essential roles in growth and absorption. Inter-species interactions contribute to plant reproduction and species propagation.
Explanation:
The interactions among plant systems such as the transport, response, and reproduction systems enable plants to function effectively in their environments. The vascular system, consisting of xylem and phloem, plays a crucial role in transporting water, nutrients, and photosynthates throughout the plant. The xylem primarily moves water and minerals from the roots to the rest of the plant, while the phloem distributes sugars produced during photosynthesis to all parts of the plant, including the roots.
Plant organ systems consist of a shoot system for above-ground growth and a root system for water and mineral absorption. Within these systems, individual organs such as leaves, stems, and roots work together to perform essential functions including photosynthesis, respiration, and nutrient transport. During reproduction, plants also interact with other species, such as pollinators and animals that disperse seeds, which are necessary for the continuation of plant species.
These interactions illustrate the concept that structure relates to function within biological systems. By understanding how systems like water potential and features like plant roots and leaves are adapted for their roles, we gain insight into the complex properties that arise from interactions within these biological systems.

Before the three-dimensional structure of DNA was discovered, scientists knew that DNA contained nitrogenous bases. The table below shows the percentages of the nitrogenous bases in a DNA sample. Which rule can be used to determine the percentages of the missing nitrogenous bases? Complete the table AND explain your answer.
Base Percent Adenine 23 Thymine ___ Cytosine 27 Guanine ____
Answer:Chargaaf's rule can be used to find out missing percentages. Thymine will be 23% and Guanine will be 27%.
Explanation:Chargaaf was a very popular scientist who worked on the DNA even before Watson and Creek discovered the DNA structure. Its even very evident that because of Chargaaf's rules, Watson and Creek were able to formulate their structure of DNA.
One of the rules of Chargaaf said that the ratio of purines to pyrimidines in a DNA is always 1:1. That means the summation of adenine and guanine is to thymine and cytosine will be 1:1. This is actually because adenine is complementary to thymine and guanine to cytosine.
Thus in the given DNA chart, adenine is 23%. So, thymine will also be 23%. Its given that cytosine is 27%. So, guanine will also be 27%. The answer can be checked as the summation of all the numbers give a total of 100%.
According to the text, what happens when organisms cannot adapt to changes in their environment?
A. They move to another environment.
B. They risk dying out.
C. Nothing happens.
D. They wait for the environment to change again.
Answer:
The correct options are A) They move to another environment.
B) They risk dying out.
Explanation:
According to natural selection, only those organisms are able to live and survive in an environment which can adapt to the changes in an environment. Such organisms reproduce and pass on their characteristics to their offsprings.
Organisms which are not able to adapt to changes in an environment either migrate to other places or die as they are not able to survive by the changes being made.
If organisms can't adapt to environmental changes, they risk dying out, which can lead to extinction. Adaptation is key for maintaining internal stability and handling external changes.
Explanation:When organisms cannot adapt to changes in their environment, they risk dying out. The inability to adapt may lead to extinction, as has happened with the majority of species in evolutionary history. Adaptation is crucial for survival because it enables organisms to maintain their internal environments and respond to external changes. If a species develops a disadvantageous mutation, competing species that remain unchanged could become relatively better adapted without any change on their part. This concept reflects the importance of continuous adaptation just to maintain a species relative standing in its ecosystem.

Final answer:
The disadvantage of wind energy is that it may alter habitats and harm birds, despite being renewable and not producing greenhouse gases.
Explanation:
Among the listed options, the disadvantage of wind as an energy source is C. It may alter habitats and harm birds. While wind energy does not use fossil fuels, is a renewable resource, and does not produce greenhouse gases, it can have negative impacts on wildlife. Wind turbines can pose a significant threat to flying creatures like birds and bats, who may collide with the rotors. In addition, the construction of wind farms can alter natural habitats and landscapes. Although these impacts are a concern, they are generally considered to be less damaging than the effects of fossil fuel consumption on the environment.
Wildebeest and red-billed quelea engage in resource partitioning, where each uses a different
part of the grass. Explain how this works.
Answer:
In an environment where resources such as food are being depleted, organisms within a species and organisms belonging to different species need to find a way in which they can coexist and survive in the environment. This is done by the organisms so in order to avoid competition. Resource partitioning is a method that organisms use for survival by dividing their resources so that there is lesser competition.
The wildebeest and the red-billed quelea are also using this phenomenon in order to survive. They have divided their part of the grass so that there is lesser competition and both of the species are able to coexist.

O
B. Serine
O
c. Huanine
O
D. Polymine
Final answer:
Adenine is one of the bases found in DNA, pairing with thymine to form part of the DNA structure through hydrogen bonding.
Explanation:
One of the bases found in DNA is adenine (A). Adenine is one of the four nitrogenous bases in DNA, along with thymine (T), cytosine (C), and guanine (G). These bases pair up to form the rungs of the DNA ladder, with adenine pairing specifically with thymine through hydrogen bonds. The structure of DNA is stabilized by these complementary base pairings, and any change in these pairings, such as an adenine replacing a cytosine, could potentially alter the DNA structure and thus the genetic information it carries. In the context of nucleic acids, these bases are attached to a deoxyribose sugar and a phosphate group to form a nucleotide.

Which of the following is true of an isobaric process
A. Temperature is constant.
B.Q = -u
C. Pressure is constant.
D. W = PV
Answer:
Pressure is constant & W= PV
Explanation:
If you lookat this picture.You can see that temperature is changed...that means internal energy is changed.And you can see pressure is 2atm always...
and also because the volume is incresed we can calculate the work using
W=p∆v
W=2atm*1m^3
So that equation is also true for this system.
Final answer:
The true statement about an isobaric process is that pressure remains constant. It is a thermodynamic process characterized by constant pressure throughout the process.
Explanation:
The correct answer to the question is C. Pressure is constant. An isobaric process is a thermodynamic process during which the pressure remains constant. Thus, when a gas undergoes an isobaric process and does work on a piston, as in Figure 1, the work done by the gas can be represented by the equation W = PΔV, where P is the constant pressure and ΔV is the change in volume of the gas. This process should not be confused with an isothermal process, where temperature remains constant, or an adiabatic process, where no heat is transferred between the system and its surroundings.

A)Number of microbes reduces with the time.
B)Number of microbes remains constant with time.
C)Number of microbes increases at a constant rate.
D)Number of microbes increases exponentially with time.
Answer:
The correct option is D) Number of microbes increases exponentially with time.
Explanation:
As we can see from the graph, the population of the microbes is starting with a slow growth in the start but as time increases, the population starts to grow in an exponential manner. Exponential growth occurs when there is enough supply of food and other resources to support growth. But with the passage of time, the resources will start to decline and we will see a decline phase after the exponential phase has occurred.
What are the four main threats to biodiversity?
Answer:
I think the main reasons why Biodiversity is under serious threat is as a result of human activities. The main dangers worldwide are population growth and resource consumption, climate change and global warming is also a big reason. Habitat conversion and urbanisation, invasive species that dont belong, over-exploitation of natural resources and environmental degradation.
Hope this helps :)The four main threats to biodiversity are as follows:
Overexploitation.Climate change.Habitat loss.Introduction of Invasive species. What is Biodiversity?Biodiversity may be defined as the sum total of all the variety of living organisms present on the earth's surface. It includes the measure of variations at the genetic, species, and at ecosystem levels.
Overexploitation involves the elimination of a particular type of organism due to its overconsumption for the benefit of humans as well as other living organisms.
Climate change leads to severe impacts on the survivability of living entities. It includes global warming, El Nino effects, coral reef, etc.
Habitat destruction due to urbanization, or industrialization is also one of the major threats to biodiversity. The habitat gets disturbed due to human activities and interference.
The introduction of invasive species limits the resources that were part of native species. And due to this the competition increases and hence native species have to be eliminated, and biodiversity decreases.
Therefore, overexploitation, climate change, habitat loss, and invasive species are the four major threats to biodiversity.

Peppered moth simulation
Answer:
yes
Explanation:
because
The Peppered Moth Simulation is a biological illustration of natural selection. The color of these moths changed in response to industrial pollution in 19th-century England, with darker moths having a survival advantage because they were better camouflaged. This color balance has been shifting back as air quality improves.
The Peppered Moth Simulation is a classic example of adaptation and survival in biology, often used to demonstrate the concept of natural selection.
In the mid-19th century, nearly all peppered moths in industrialized areas of England were dark (or 'melanic'), whereas before industrial pollution the majority were 'typica' or lighter colored. The color change is believed to have been a response to pollution: dark moths were better camouflaged against soot-covered trees and therefore less likely to be eaten by birds. This is known as industrial melanism.
Tests carried out in various ways have shown that the large changes in frequency of the dark moth could not have happened by chance, which indicates natural selection. With improvements in air quality, the 'typica' variety of the moth is again predominant today.
