How can we use rocks to determine how an area used to look in the past?

Answers

Answer 1
Answer: You could use rocks by observing the dust and dirt on it, and then you could see how much cleaner/worse the ground or earth was back then.
I hope I helped! =D
Answer 2
Answer: Depending on how deep the rock was in the ground or the sediment around it scientific researchers in the GEO category can study the rock and find out.

Looking also at the bones or dirt you can tell by the clay or even the aged looks of it's outer physical appearance.
 
If you look at the inside of a rock , Geologists can run tests on it and find the actual age of the rock.

I really hope that this helps you out a lot.

 Mitosis


Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. 

How do plants get energy? (Cut out project) ​

Answers

Answer:

Plant cells obtain energy through a process called photosynthesis. This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. ... Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants.

Final answer:

Plants use the process of photosynthesis to convert sunlight into chemical energy, stored in glucose. This stored energy is then made available for use by the plant through cellular respiration.

Explanation:

Plants get their energy primarily from the process of photosynthesis, which converts solar energy (sunlight) into chemical energy. Sunlight is captured by green plants, algae, cyanobacteria, and photosynthetic protists, organisms that convert the solar energy into glucose. This glucose is then used by the plant for growth and development. The chemical energy in glucose is stored in its chemical bonds and is released when these bonds are broken in a process called cellular respiration . During cellular respiration, the energy from the glucose bonds is converted into a form that can be used by all living organisms. An example of this process is shown in an oak tree that utilizes sunlight to create sugar and other organic molecules, which it then uses for energy.

Bobby has labeled the following diagram of a cell. His science teacher tells him it is perfect except for one error. Evaluate the diagram and choose the option that describes how Bobby's diagram can be corrected cell membrane nucleus cell wall cytoplasm The cell membrane should be the outermost layer of the cell The cell does not have a cell wall, only a cell membrane This type of cell does not contain a nucleus This type of cell does not contain cytoplasm.

Answers

The answer should be:

This type of cell does not contain a nucleus.

Here is why:

The type of cell that Bobby is looking at is what you call a prokaryote. These are simple unicellular organisms that do not contain a nucleus. They also do not have membrane-bound organelles, so they are just simply floating around the cytoplasm. What that should be labeled as though is nucleoid instead.

This type of cell does not have a nucleus because it is a prokaryote.

I need 10 facts about Hurricanes for Science

Answers

Hurricanes are large, spiraling tropical storms that can pack wind speeds of over 160 mph and unleash more than 2.4 trillion gallons of rain a day.The deadliest U.S. hurricane on record was a Category 4 storm that hit the island city of Galveston Texas. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge.The difference between a tropical storm and a hurricane is wind speed – tropical storms usually bring winds of 36 to 47 mph, whereas hurricane wind speeds are at least 74 mph.Hurricanes rotate in a counter-clockwise direction around the eye. The rotating storm clouds create the "eye wall," which is the most destructive part of the storm.Hurricanes are classified into 5 categories, based on their wind speeds and potential to cause damage. Names can be "retired" if a hurricane has been really big and destructive. Retired names include Katrina, Andrew, Mitch and most recently Sandy.When the National Hurricane Center began giving official names to storms in 1953, they were all female. This practice of using only women’s names ended in 1978.The costliest hurricane to make landfall was Hurricane Katrina, a Category 5 storm that slammed Louisiana in August of 2005. Damages cost an estimated $108 billion.

How does the immune system work together with the circulatory system to function properly? A.
The immune system's red blood cells fight and destroy foreign antigens.

B.
White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.

C.
The circulatory system's arteries cause the immune system to work harder by bringing oxygen-depleted blood to the infection site.

D.
Red blood cells released by immune cells cause increased blood flow to the infection site; this increased blood flow brings other red blood cells to the area more quickly.

Answers

The answer is probably B because white blood cells are part of the immune system, so help to fight diseases. The circulatory system helps to move the white blood cell around the body. Also, pathogens are disease causing organisms, and as you can see, they all relate very well. Hope i helped, have a nice day.
