an adaptation is A a trait that helps an organism survive in its enivironment
Answer:
True
Explanation:
The given statement is true. An adaptation is any characteristic that helps an organism survive or reproduce. As the environment changes, organisms that inhabit it have to change as well in order to survive. The changes they go through can be physical or behavioral. For example, giraffes have very long necks so that they can reach the leaves of tall trees, and birds have very light bones so that they can fly. This is how species continue to thrive for a very long time.
If a sample originally had 120 Adams of carbon 14 how many atoms will remain after 17,190 years
Answer:
15 atoms
Explanation:
About 15 atoms out of the 120 Adams would remain.
Generally, the half-life of a substance is the time it takes for one-half of that substance to disintegrate.
Carbon 14 has a half-life of approximately 5,730 years. 17,190 years means that the sample had stayed for 17,190/5,730 which is equal to 3 carbon-14 half-lives.
Out of 120 Adams,
the first half-life will reduce 120 to 60 Adamsthe second half-life will reduce 60 Adams to 30 Adamsthe third half-life will reduce 30 Adams to 15 Adams.Hence, at the end of the 17,190 years, approximately 15 Adams would remain.
what is the next number of the sequence?
0.99, 9.9, 99, 990, ____
I believe the next number is 9900
Reason: To get the next number in the sequence, move the decimal point
0.99 —> 9.9
9.9 —> 99.
99. —> 990.
990. —> 9900.

3. Explain how the Gulf Stream (a warm ocean current) effects the climate of Northern Europe.
Answer:
These currents transfer heat from the tropics to the polar regions, influencing local and global climate..
The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about 150 times more water than the Amazon River. The current moves along the U.S. East Coast across the Atlantic Ocean towards Europe ...The heat from the Gulf Stream keeps much of Northern Europe significantly warmer than other places equally as far north.
Answer:
The Gulf Stream, located in the north Atlantic Ocean, has an important effect on climate, transportation by sea, and the circulation of nutrients and waste in the ocean. It works together with the North Atlantic Drift to bring warm air from equatorial regions across Europe. This changes Europe’s climate by providing mild temperatures and more rain. As a result, farmers can grow more crops, and fewer freezing temperatures damage goods.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.
Answer:
You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.
The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

Water that falls onto land surfaces is either soaked into the ground or flows downhill into a body of water. The water that soaks into the ground is called groundwater.
Soil and rock that allow this water to pass through them are called ________.
A. aquifers
B. compacted
C. permeable
D. runoff
The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.
What is groundwater?Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.
An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.
Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Match each underlined word to its correct meaning based on the context of the sentence. Tom had long been picking his way cautiously through this treacherous forest; stepping from tuft to tuft of rushes and roots, which afforded precarious footholds among deep sloughs. It was a dreary memento of the fierce struggle that had taken place in this last foothold of the Indian warriors. He was sulky, however, and would not come to terms: she was to go again with a propitiatory offering, but what it was she forbore to say. At this propitious time of public distress did Tom Walker set up as a usurer in Boston.

Cathy's favorite salad dressing is a liquid with particles of salt, pepper, and garlic. When comparing a spoonful of salad dressing to a cell, what would the liquid be equivalent to? What would the particles be equivalent to?
Answer:
Liquid equivalent to "cytoplasm" and the particles equivalent to "organelles".
Explanation:
While comparing a liquid salad dressing to a cell, the liquid will be equivalent to "cytoplasm" because cytoplasm is a thick solution present in each cell that made up of water, salts, and proteins.
The particles would be equivalent to "organelles" because as particles float in liquid salad adding flavours to the salad likewise organelles are present in a cell floating in the cytoplasm that performs a specific function.
Hence, the correct answer is " liquid will be equivalent to "cytoplasm" and the particles will be equal to "organelles".
