The fossil record reveals that the diversity of flowering plants and the diversity of certain insect groups increased at the same time. How might you explain this?
Answers
Answer:
Insects and flowers are connected with each other for several life purposes such as for food, habitat and pollination.
The cause of diversity in flower and insects is associated with the process of pollination. In the process of pollination, both insects and flowers are mutually get benefits.
Insects move flower to flower in search of food and in the process it also carry pollen from flower to flower as well. Through insects the pollen reaches to different flower and show diversity and at the same time insects feed on various types of flowers and reproduce generation with variations.
Hence, the process of pollination makes a relationship between flower and insects diversity at the same time.

Fossil fuels are preserved remains of animals and plants. They record documents of diversity of life forms. Paleontologists are people who study about fossils.
What are fossils?Fossils are decomposed plants and animals. They can be the preserved remains or traces of living things. Thus the first statement is correct. The second statement that they record documents the diversity of life forms is correct since, by studying fossils we can find which types of living things were there in an area.
The people who study on fossils are called Paleontologists. The fossil formed when an animal walked in mud long ago and then the mud hardened into rock is an example of trace fossils. Most fossil are found in sedimentary rocks.
Fossils tell about both land and water plants and animals. A paleontologist finds a fossil of a fish on a mountain. She can infer that the area was once underwater. Not every but most dead animals and plants form fossils.
No condition can change chemical molecules of a fossils into that in living cells. The oldest rocks contains both complex and simple organisms. Thus the statement is true.

what is an example is a form of precipitation?
Answers
Answer: hail, snow, sleet, rain, graupel, ice pellets and drizzle are the main forms of precipitation.
Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

Which correctly lists the three elements that geologists measure to determine the age of an organism’s remains?
A. argon, nitrogen, and carbon-12
B. carbon-14, nitrogen, and carbon-12
C. nitrogen, potassium, and carbon-14
D. carbon-12, potassium, and argon
Answers
Answer:
It’s Carbon -12,potassium, and argon.
Explanation:
The three elements used by geologist to measure the age of organism’s are carbon-12, potassium, and argon. Thus, option D is correct.
Which method is used to determine of age of organism’s remains?The age of organism’s remains is determined by two methods of calculation such as carbon dating and by radioactive calculations as all living things are made up of carbon. It calculates the age by estimating at what time the fossil was alive.
Now a days, instead of the decay of carbon-14 and nitrogen-14, radioactive isotopes are used for determining the age of organism’s remains, known as Radiocarbon dating.
The radioactive isotopes of different elements present in our environment. The older elements are uranium, argon etc are used to measure age of a fossil.
The use of older naturally available radioactive elements is more successful in determination of age of organism’s remains. Hence, option D is correct.

Which of these factors is involved in earthquake formation?
Answers
Answer:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other.

Please someone answer I need help.
Answers
Answer: The Low Pressure systems will usually be found more North where it gets verycold but can really happen anywhere, and High pressure systems are usually found in the Southwest during winter.
Explanation:
High Pressure:A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward. On a weather map, you may notice a blue H, denoting the location of a high pressure system.
Low Pressure:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps, a low pressure system is labeled with red L.

4. How does using a fan lowers the greenhouse gas emissions?
5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?
Answers
Answer:
Explanation:
1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.
2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption
3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.
Answer:
Explanation:
1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.
2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.
3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.
4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while
Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,
Thus fan helps to reduce greenhouse gas emissions.
5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.
