Answer:
Most ozone (about 90%) is found in the stratosphere, which begins about 10–15 kilometers (km) above Earth's surface and extends up to about 50 km altitude. The stratospheric region with the highest concentration of ozone, between about 15 and 35 km altitude, is commonly known as the “ozone layer”
What does RNA have that DNA does not ?
Answer:
The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation. DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

How does the Earth get its brand new NITROGEN?
Answer:
Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. Nitrogen is a volatile element that, like carbon, hydrogen and oxygen. Nitrogen makes up 78 per cent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

What is a biome?A biome is an ecological unit that depicts the occurrence of a biological community in response to the particular climate and the environment.
Biomes support variety of habitats across the different continents. Various biomes together constitute a biosphere.
A biome is identified on the basis of temperature and precipitation it receives annually. The presence or existence of organisms is dependent on these two factors.
Based on topography, biomes can be classified into terrestrial, fresh water and marine biomes.
Some of the well known examples of biomes include tundra region, taiga region, grasslands, desserts and forests.
There are also special types of biomes known as ecotones where the two biomes merge. Salt marshes are the example of ecotone.
Thus, biome is the life supporting unit in ecology.

1. How would you describe the movement of the sun over 30 minutes?
Answer:
The earth rotates from west to east. The sun does not move around the earth in 30 minutes. The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates.The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.Have an amazing day friend! :D

The gallbladder provides ________ that aid(s) in transport of lipids across the intestinal membrane.
The gall bladder provides bile salt.
The gall bladder is a small pear-shaped organ that is located at the abdomen inferior to the liver.
This organ stores and releases the bile salt produced from the liver.
The bile salt is released through the bile duct into the duodenum of the small intestine.
The bile salt is use to emulsify fat thereby aiding it's transport across the intestinal membrane.
Therefore, the gall bladder provides bile salt that aids in transport of lipids across the intestinal membrane.

Examine the comparison between a eukaryotic cell and a prokaryotic cell. Which two lettered choices provide a comparison of structures that encode genetic information for the cells? A) A and D B) B and D C) C and D D) None of these choices, as prokaryotic cells do not contain DNA
I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

At 2s, your velocity is 4.5m/s. Calculate your acceleration.
Your Answer:
Answer
units
Answer:
2.25 m/s^2
Explanation:
Acceleration is the speed which you are increasing by per second. Therefore to find acceleration all you need to do is divide the change in velocity (4.5) by the time (2). Your units than become (m/s)/s or m/s^2.

Answer:
it would be a disaster
Explanation:
The centrifugal force would pull hundreds of feet of water toward the Earth's waistline.
Answer:
If the Earth were to spin faster, the tides would change because the fast speeds would increase stress; making tighter circles of convection. This would cause more natural disasters like hurricanes, cyclones, and tsunamis.

Students observe several slides of tissue cross-sections under the microscope. They are asked to develop a key system to classify the slides as coming from either monocot or dicots. What key system should the students develop
As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the vascular bundles.
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain randomly scattered bundles located throughout the stem. On the other hand, dicots have their vascular bundles more neatly organized in concentric circles. These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.
