b. Write the following in ordinary notation: 3.02 x 10-5
c. Evaluate the following: (3.3 x 10-4mL) = (1.1 x 10-6 mL)
Answer:
a. 0.03054 b. 0.000032 c. sorry I am not perfect
Explanation:
a. In the number 0.03054 , you need to move the decimal point two places to the right to get to 3.054 (which is between 1 and 10). Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied 3.054 by 10−2 . Think about it: 3.054×10−2=0.03054 . b. Answer: 0.0000302 Step-by-step explanation: When 10 is to the power of a negative number, "move" the decimal dot left. 10⁻⁵ means to "move" the decimal 5 times to the left. 1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02). 0000003 . 02 2. Count 5 place values over. 00←0←0←0←0←3 . 02 3. Put the decimal behind the digit. 00 . 0000302 4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal. 0.0000302 <= Final answer c. sorry but I am not perfect at thisA. 0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams
B. 3.02 x [tex]10^-^5[/tex] = 0.0000302
C. 3.3 x [tex]10^-^4[/tex] mL= 300
Powers of 10 are used in scientific notation to express extremely large or extremely small quantities. The formula is "[tex]\rm a * 10^b[/tex],"
where "a" is an integer representing a value between 1 and 10 (inclusive), and "b" is an integer representing a power of 10.
To write 0.03054 grams in scientific notation, we move the decimal point three places to the right to make the number between 1 and 10. this results in:
0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams
To write [tex]3.02 * 10^-^5[/tex] in conventional notation, as indicated by the exponent, we move the decimal point five places to the left. this results in:
3.02 x [tex]10^-^5[/tex] = 0.0000302
To evaluate (3.3 x [tex]10^-^4[/tex] mL) / (1.1 x [tex]10^-^6[/tex] mL), we divide the numbers in the numerator and denominator:
[tex](3.3 * 10^-^4 \rm mL) / (1.1 * 10^-^6 \rm mL) \\= (3.3 / 1.1) * (10^-^4 / 10^-^6) \\= 3 * 10^2[/tex]
Therefore, (3.3 x [tex]10^-^4[/tex] mL) is equal to 300.

Answer:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing. They do not react because they have no electronegativity and no "extra" electrons
Explanation:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.
What is electronic configuration of carbon?Carbon atomic number is 6. Its electronic configuration is 1s2 2s2 2p2. As you can see from the electronic configuration the inner shell has 2 electrons and the outer shell with principal quantum number 2 has 4 electrons.
An atom is made up of electrons, protons and neutrons. Both protons and neutrons are located in the nucleus of the atom, while electrons are in the shell/s. The shell of an atom is the orbit on which the electrons revolve around the nucleus. The number of shells in an atom extends from the first, n =1, to infinity, n = ∞, depending on the number of electrons in the given atom.
The first shell, n =1, is the ground state and can only contain a maximum of 2 electrons. The inner shell contains two electrons and the outer shell contains four electrons.
Therefore, Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.

if you examined a potato cell under a microscope how could you tell that it was a plant cell?
Answer:
When looking at a plant cell and an animal cell, you will notice one significant difference (though there are many more). A plant cell has one large central vacuole, whereas an animal cell has many.
Explanation:
Have a great day, and spread some positivity!
A plant cell can be identified by the presence of a cell wall, a large central vacuole, and chloroplasts.
The cell wall is a rigid structure that surrounds the cell membrane. It is made up of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. Animal cells do not have a cell wall.
The central vacuole is a large space filled with water. It is located in the center of the cell. The central vacuole helps to maintain the cell's shape and turgor pressure. Animal cells do not have a central vacuole.
Chloroplasts are organelles that contain chlorophyll. Chlorophyll is the green pigment that allows plants to photosynthesize. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Animal cells do not have chloroplasts.
If you examined a potato cell under a microscope, you would be able to see these features. The cell wall would appear as a thin, clear layer around the cell. The central vacuole would appear as a large, empty space in the center of the cell. The chloroplasts would appear as green, oval-shaped organelles.

1. List 2 interactions between the earth spheres and the water cycle.
2. List 2 interactions between the earth spheres and the carbon cycle.
3. List 2 interactions between the earth spheres and the nitrogen cycle.
Answer:
The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.
Explanation:
Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.
The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.
The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.
In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.

What will most likely happen if the human population continues to grow and carelessly emit gases? (L17.20)
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface creating a hole in the ozone layer
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth causing earthquakes.
Too many greenhouses gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing volcanic eruptions.
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing global warming.
Answer:
I think it would be the goal warming one :)
If the human population continues to grow and emit gases then this may lead to global warming. The green house gases in the atmosphere block heat and hence cause global warming. Thus, the correct option is D.
What is Global warming?Global warming is the change in climate, referring to the long-term increase in the planet's temperature. It is caused by increased concentrations of greenhouse gases in the atmosphere. This is mainly because of human activities such as burning fossil fuels, pollution, and farming.
The greenhouse gases in the atmosphere absorb the heat. They radiate this heat. Some of the heat will leave the Earth, some of it will be absorbed by greenhouse gases, and some of it will get back at the planet's surface. With the increase in the greenhouse gases, heat will stick around, warming the planet.
Further increase in the green house gases lead to melting of glaciers and increased precipitation. This will change the climatic conditions globally.
Therefore, the correct option is D.

Compare geologic time with the geologic column . (Earth science )
Answer:
The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).

The coordinated action of two types of myofilaments, actin and myosin, results in muscle contraction. The muscles contract as actin filaments slide over myosin filaments. When the muscle is in a relaxed state, the myosin heads are ready to bind with the actin filament. However, they are not able to bind due to
a.
the absence of ATP
b.
a high concentration of Ca++ ions
c.
blockage of the attachment site
d.
alcoholic fermentation
Answer:
I think due to absence of ATP but I'm not sure.. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available.
Myosin heads are ready to bind with the actin filament they are not able to bind due to the absence of ATP.
How two myofilaments involved in muscle contraction?Muscle contraction results from an intercommunication between the actin and myosin filaments which generate movement relative to one another.
What happens to the actin and myosin filaments when a muscle contracts?Myosin movement appear to be a kind of molecular hop. The myosin reaches forward, binds to actin, contracts, releases actin, and then reaches forward again to bind actin in a new cycle.
What happens to actin and myosin during muscle relaxation?Relaxation occurs when nerve stimulation stops. Calcium gets moved back into the sarcoplasmic reticulum shattering the link between actin and myosin. Actin and myosin then return to their unbound state causing the muscle to relax.
