Answer:Acceleration is present in car B and E.
Deceleration is present in car C.
No change in velocity is seen in car A and D.
Explanation:Acceleration is defined as the rate of change of velocity with time and is having a dimensional formula of [tex]distance /time ^2[/tex]
When a body is having acceleration, the body has more final velocity than initial velocity. Deceleration is the opposite of acceleration which is seen when the body has less final velocity than initial velocity.
In A:
Initial velocity= 30 km/hr.
Final velocity= 30 km/hr.
So change in velocity = 30-30 km/hr = 0 km/hr.
So no acceleration is present.
In B:
Initial velocity= 0 km/hr.
Final velocity= 20 km/hr.
So change in velocity = 20-0 km/hr = 20 km/hr.
So acceleration is present.
In C:
Initial velocity= 20 km/hr.
Final velocity= 0 km/hr.
So change in velocity = 0-20 km/hr = -20 km/hr.
So deceleration is present.
In D:
Initial velocity= 0 km/hr.
Final velocity= 0 km/hr.
So change in velocity = 0-0 km/hr = 0 km/hr.
So no acceleration is present.
In E:
Initial velocity= 20 km/hr.
Final velocity= 30 km/hr.
So change in velocity = 30-20 km/hr = 10 km/hr.
So acceleration is present.

What is the theory of plate tectonics? Explain this scientific theory, making sure to include the following terms in your response: Pangaea, continental drift, convection, gravity. Use 3-5 sentences and proper conventions (spelling, grammar, punctuation, etc.) to respond. Put all answers in your own words.
Answer:
Plate tectonics is a scientific theory that explains how seven continents are formed. Around 240 million years ago, all these continents were together in the form of a super-continent (called as pangaea). However, due to convection (circular motion of molten material inside Earth) and gravity, supercontinent started breaking apart. These parts started moving away from each other leading to the continental drift.

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%.
Which is one of the bases found in DNA?
O
A. Adenine
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.
Can DNA be replicated while the DNA is twisted in its double helix?
Answer:
The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. In DNA replication, the double helix unwinds and each separated strand is used to synthesize a new strand.

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.

A) Nazca Plate and Antarctic Plate
B) Pacific Plate and Indian-Australian Plate
C) Indian-Australian Plate and Antarctic Plate
D) Nazca Plate and Pacific Plate
Answer:
B) Pacific Plate and Indian-Australian Plate
Explanation:
In convergent boundaries, one of the involved plates sinks under the other plate in a process known as subduction. The correct option is B. Pacific Plate and Indian-Australian Plate.
Plate boundaries
There are three types of plate boundaries according to the interaction between plates.
Plate boundaries can be either Convergent, divergent, transforming
Convergent BoundaryCollision area between two plates.Two oceanic plates might collide, or one oceanic plate with a continental one.In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.The thicker and older plate subduces under the other plate.Volcanoes get formed on the superior plate since magma flows over it.Plates's movement might produce earthquakes.
Example
An example of a convergent boundary is the union between the Pacific Plate and Indian-Australian Plate.
The Pacific plate is subducting under the Indian-Australian Plate since it is the oldest and thickest one.
These movements originated the Kermadec Trench and the Tonga and Kermadec island arcs.
The correct option is B) Pacific Plate and Indian-Australian Plate.

arteries, and veins by themselves can't do anything, but if they are assembled in a
body, they can pump blood. What does this illustrate?
a) Evolution by natural selection
b) An emergent property
c) The one-way flow of energy in ecosystems
d) The universal genetic code of life
The given scenario illustrates An emergent property.
Explanation:
A property that explains about the functioning of any system as a whole is an emergent property. The units of that individual system will not work to give the functionality of the entire system. Fallacy of division occurs when there is a failure in the realization of this emergent property.
For instance let us take an ant colony. Ant as a single organism will not be able to attain certain works. While when they join to form a colony they together can accomplish complex and tedious tasks. Hence, in human body also cells of heart acts as an example of an emergent property as they together can accomplish the function.

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.

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.

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.
