Assuming there has been no geological activity to disturb the order of the rock layers, rock layer is (b) The oldest rocks at Location.
What are the Finding of the oldest rocks?The global is a tougher challenge than it'd seem. Earth's crust is a dynamic gadget and is constantly in motion, so rocks are always being moved around, created and melted down withinside the fantastic geological recycling programThe oldest zircon dates are 4.36 billion years. Before this study, the oldest dated rocks have been from a frame of rock called the Acasta Gneiss withinside the Northwest Territories, which can be 4.03 billion years old.

Which animal is native to a different part of the world than the other two?.
. Take 400ml milk, curd, four small clean jars with lids labelled A, B, C and D. Pour about 100 ml of lukewarm boiled milk into each jar. Add a teaspoon of curd to jar A and D. Place jar D in a refrigerator. Place jars A, B and C in a warm place. Observe the jars after four to five hours and answer these questions.
i) What do you see in jars A, B and C?
ii) Why did the milk in jars B and C not set into curd?
iii) What happened in D? Can you say why?
1. The milk will be turned into curd in bowl A due to the lactobacillus bacteria and not in other bowls B, C.
What is lactobacillus bacteria?
Lactobacillus is the bacteria required for the formation of curd and it requires an appropriate temperature for its growth. Lukewarm milk not being very much cool and hot provides that appropriate temperature and hence lukewarm milk get converted into milk.
2. Bowl B and C contains hot and cold milk that do not provide required temperature for the growth of bacteria due to which bacteria does not grow in them and they are not converted into curd.
3. Bowl D placed in refrigerator, so the the bacteria unable to divide because they does not get the required temperature and doesn't changed into curd.

Why is it important to protect ecosystems? What could happen to the biotic and abiotic factors if we don’t take care of them?
It protects the resources and organisms that depend on one another in the ecosystem
What would be the impact on the organism and the biomes?
A rise in temperature in the tundra for the polar bears:
They would get overheated since they are prepared for the colder temps with their fur-also causes the ice to melt and alter its food supply
A decrease in rainfall for the flowers in the rainforest:
They would likely die due to a lack of water
A decrease in temperature for jackrabbit in the desert:
They would get very cold since they are used to the extreme heat
An increase in temperature for the black bear in the temperate deciduous:

Describe the relationship between the mass and metabolic rate of whales and seals in the Antarctic habitat. Explain why less massive species tend to require more energy to survive.
Organisms that have a higher metabolic rate due to large mass and hence require less energy
What is the relationship between metabolic rate and mass?We know that metabolic rate at which individual species carry out the process of metabolism.
It should be know that larger organisms that have a higher metabolic rate due to large mass and hence require less energy since metabolism produces heat. This owed to the fact that large size implies greater metabolism. Therefore, less massive species tend to require more energy to survive.

Analyze the pyramid representing the energy flow through an ecosystem. Select the phrases that accurately describe the flow of energy in this ecosystem according to the image here. Select all that are correct.
A) Top carnivores obtain the maximum energy from the ecosystem.
B) Herbivores have more energy available to them than carnivores.
C) There should be fewer tertiary consumers than secondary consumers.
D) Soil organisms recycle nutrients but not energy back into the ecosystem.
E) Of the energy that is available to the producer level, only ten percent is available to the tertiary consumers.
In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.
Energy pyramid in the ecosystemThe producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.
The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.
Thus, one can effectively conclude that:

if destructive interference occurs between a wave with a six foot trough and a three foot crest, what factors will determine the height of the resulting wave?
Destructive interference formed when the two meeting waves are out of phase and in some cases, the two wavers maxima are 180 degrees out of phase. The height of waves is determined by the wind speed, how the long wind blows, and crucially the fetch.
The longer the duration of wave, the larger will be the wave heights. The longer the fetch, the large will be wave heights.
What is interference?Some waves jump to cross over or meet with each other. When they do, the reaction between the waves is called interference.
If at a given location, both interfering waves are supersede in the same direction (both up or both down) then it is known as constructive interference.

What is hypertension AND how is it prevented?
Answer:
Hypertension is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure.For most adults, there's no identifiable cause of high blood pressure. This type of high blood pressure, called primary (essential) hypertension, tends to develop gradually over many years. Some people have high blood pressure caused by an underlying condition. This type of high blood pressure, called secondary hypertension, tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary hypertension, including:
Obstructive sleep apnea
Kidney disease
Adrenal gland tumors
Thyroid problems
Certain defects you're born with (congenital) in blood vessels
Certain medications, such as birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs
Illegal drugs, such as cocaine and amphetamines
Answer:
Hypertension is when blood pressure is too high. It can be prevented by doing things such as eating healthier foods, not doing any smoking, being physically active, getting enough sleep, and maintaining a healthy weight.
