Kinetic energy = 1/2 * mass * velocity^2 so Ke = 1/2*(155*10^3 g)*18^2 which is 25,110,000 joules.
Answer:
31,000 J
Explanation:
using KE = 1/2mv^2 (m stands for mass, v stands for velocity) we can do the math and the answer is 31,000J because the mass in the question listed is 155 kg and the velocity (aka speed) is 18 m/s.
kinetic energy (aka KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared.
(1/2 * 155 kg) * 18 m/s^2 = 31,000J

When scientists uncover a fossil, they record the precise location where the fossil was found. Does this location provide useful evidence for conclusions about the fossil and evolutionary processes?
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
B. No. Evidence for evolution comes only from body structures, not the environment of organisms.
C. Yes. Evolution occurs only in certain locations on Earth, and not others. D. No. Fossils and living species are distributed evenly across all of Earth's land and water.
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
Answer:
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
Explanation:
Data shows that presence or the absence of the continents and the islands provides evidence of the descent and shows us the specification of species. As the same species would be found in the same habitats that are capable of supporting a particular species in a geographical area as Africa or South America. Evidence have also been found in Australia that has marsupials like the kangaroos and quills that were not present in Africa and in small numbers in south America. Similarly, the fossils are found in areas know adjacent to each other and through the process of the continental drift, they diverged in wide geographical areas.Which of the following is the study of the independence of all living things and their environment?

What term is used for the study of non living parts of earth?
A. Chemistry
B. Geology
C. Ecology
D. Biology
Correct option is B. The study of nonliving parts of Earth is called geology, a physical science that focuses on the solid aspects of Earth and other celestial bodies.
Physical Science and Earth's Nonliving Components
The term used for the study of nonliving parts of Earth is geology. Geology is a physical science field that focuses on the solid Earth, the rocks of which it is composed, and the processes by which they change. This contrasts with biology and ecology, which study living components and their interactions with the environment. Chemistry, while part of the physical sciences, focuses on the composition, structure, properties, and change of matter. Therefore, the correct answer to the question is B. Geology.
Understanding geology provides insights into Earth's history and is essential for various applications such as resource extraction, environmental protection, and studying the solid features of celestial bodies. It's an integral part of physical science, along with other fields like astronomy, physics, and chemistry, which together contribute to the comprehensive study of nonliving matter.

Which best defines homeostasis
Homeostasis is the ability of an organism to adjust its internal environment in order to maintain a stable equilibrium regardless of the external changing conditions.
Answer
The best definition of homeostasis is:
maintaining a stable internal environment
Explanation:
Homeostasis: is a condition where organisms maintain their internal conditions in response to the external changes.
To proper functioning of the body, the function inside the body needs to be controlled. Homeostasis is the way by which constant internal condition is maintained.
Some of the example of Homeostasis:
Body temperature: In order to control body temperature, enzymes present in the body play a major role.water content: The level is controlled by water loss from the lungs by the exhaling process, from the skin by the sweating process in order to maintain the balance of water level in the cell.the diagram below represents the time a cell spends in the two main phases of the cell cycle. what is happening in the phase represented by the yellow area?
D) the cell is dividing
Answer:
The correct answer will be option-D.
Explanation:
The cell cycle is the sequential steps of events which explains the duplication of the genetic material and division of the cell into daughter cells.
It usually takes place in 24 hours where it is divided into four phases: Gap 1 (G₁), Synthesis phase, Gap 2 (G₂) and Mitotic phase (M phase). M phase can be marked easily as it takes place during the short period of time usually in one hour.
In the given question, the marked area represents the shortest phase or M phase during which cell divides its nucleus and cytoplasm, therefore, is considered the cell division phase.
Thus, option-D is the correct answer.
Which if the following statements best explains why the plant life cycle is described as an "alternation of generations"?
Answer
Hi,
The correct answer option is (D). The plant life cycle goes back and forth between a haploid stage and diploid stage
Explanation
Two distinctive stages exist in plant life namely; the gametophyte stage and the sporophyte stage. When plants mature, the diploid sporophyte produce spores by the process meiosis that later divides by mitosis to produce a haploid gametophyte. The newly formed gametophyte produces gametes and the cycle starts once more.

Based on the information in the table, which type of oil is the worst for a healthy lifestyle?
A. Sunflower oil
B. Olive oil
C. Coconut oil
D. Maize oil
Vegetable oils are used for cooking and are based on unsaturation and saturation. Coconut oil is the worst for a healthy lifestyle. Thus, option C is correct.
What are saturation and unsaturation?Saturation and unsaturation are differentiated based on the presence of the number of the bonds. The saturated bonds have single while the unsaturated ones have double bonds. The presence of the unsaturated bonds in oil makes them good to consume.
Coconut oil has the highest saturation and the least polyunsaturated content which makes it the most unfit to consume. The oils with the most polyunsaturation make them good for consumption.
Therefore, coconut oil is the worst for a healthy lifestyle.

Offspring have no features like the parent.
Offspring have some features like the parent.
First, to be able to answer this, you need to know the definition of asexual and sexual organisms. On a quick basis, sexual organisms need to parents, male and female, to make a child. Asexual organisms, on the other hand, only need one parent to have an offspring. Sexual organisms have a mix of both of their parents DNA. Asexual organisms are a replica of the parent.
So, the correct answer is:
Offspring are genetically identical to the parent.
Answer: The answer is "Offspring are genetically identical to the parent."

As precipitation infiltrates into the subsurface soil, it generally forms an unsaturated zone and a saturated zone. In the unsaturated zone, the voids—that is, the spaces between grains of gravel, sand, silt, clay, and cracks within rocks—contain both air and water. Although a lot of water can be present in the unsaturated zone; why can't this water be pumped by wells?
A)
Soils, like clay, absorb water quickly.
B)
Sinkholes collect water above the water table.
C)
Land with no slope lets water runoff at a fast rate.
D)
Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Answer:
d
Explanation:
Answer:D) Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Explanation: Water in the subsurface soil zone is held together by capillary forces. It is also used by plants to carry out their life processes. The soil zone is crisscrossed by roots, openings left by decayed roots, and animal and worm burrows, which allow the precipitation to infiltrate into the soil zone. Water can also evaporate directly into the atmosphere.
