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.

Beaker A contains 6 liters of water and 1 osmole of glucose. Beaker B contains 10 liters of water and 2 osmoles of glucose. Which one has the greater osmolarity and by how much?
From the ratio of glucose osmole to the volume of water in the two beakers, beaker B would have the greater osmolarity.
The term osmolarity refers to the number of particles of solutes or osmoles of substances per liter of solution.
In this case, the osmolarity of beaker A can be calculated as;
1 osmole/6 liter
= 0.167 osmolar
The osmolarity of beak B can be calculated as:
2 osmoles/10 liter
= 0.2 osmolar
Thus, beaker B with 0.2 osmolar has the greater osmolarity when compared to beaker A with 0.167 osmolar.
More on calculating concentrations can be found here: rainly.com/question/17329736
Answer: B
beaker A is 0.16 Osm/L and Beaker B is 0.2 Osm/L Beaker B has a greater osmolarity by 0.04 Osm/L

a. Write the following number in scientific notation: 0.03054 grams
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.

What is the definition of period?
1) cycles per second
2) vibrations per hour
3) seconds per cycle
4) Number of vibrations
Period is defined as cycles per second. Therefore option (A) is correct.
What are the characteristics of period?A period T is the time required for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases.
The unit for time period is 'seconds'. Frequency and time period are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T. Orbital period is the time for something to go round (orbit) something else.
Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

Which statement correctly describes fertilization? (1 point)
Fertilization is the process in which the zygote undergoes mitosis and forms a group of cells.
O Fertilization is the process in which male and female gametes fuse and form a fertilized egg.
Fertilization is the process in which the embryo develops a fluid-filled sac for protection.
O Fertilization is the process in which male and female gametes shift to align with the birth canal.
Answer:
B
Explanation:
Fertilization is the process in which male and female gametes fuse and form a fertilized egg. The correct option is B.
What is the process of fertilization?During fertilization, sperm and egg combine to form a zygote in one of the fallopian tubes.
The zygote then travels down the fallopian tube and develops into a morula. The morula develops into a blastocyst once it reaches the uterus.
The blastocyst then burrows into the uterine lining, which is referred to as implantation.
The sperm binds to the secondary oocyte via the corona radiata, a layer of follicle cells on the outside of the oocyte.
Fertilization is divided into three stages: sperm capacitation and acrosome reaction, sperm-egg binding and fusion, and cortical reaction and oocyte activation.
In a nutshell, sperm capacitation takes place in the female genital tract and prepares sperm cells for the acrosome reaction.
Thus, the correct option is B.

Four students are discussing heat, thermal energy, and temperature. Claire says temperature indicates the amount of heat in an object. Hazel states that heat is a transfer of energy. Connor says that, if two objects have equal masses, the hottest object has the most thermal energy. Evan disagrees. He says that, if two objects have equal masses, the hottest object has the most heat.
Answer:
Claire and Conner are correct
Explanation:
trust me.....
Among the four students, Hazel and Connor are correct in their statements. Heat is indeed a transfer of energy, as stated by Hazel. Similarly, Connor is right in saying that if two objects with equal masses are compared, the hottest object possesses the most thermal energy. Thus, correct option is (d).
Hazel is right when she says that heat is the thermal energy that is transferred between objects when there is a temperature difference. This is a cornerstone idea in thermodynamics. The claim made by Claire is untrue because temperature really measures the average kinetic energy of an object's molecules rather than the quantity of heat it contains.
The idea that thermal energy, which is connected to the kinetic energy of particles in an object, rises with temperature is supported by Connor's assertion. Consequently, the object with a greater temperature does actually have more thermal energy when two things have equal masses.
Evan's argument against Connor's assertion is unfounded. Temperature measures the intensity of heat, not the overall amount of thermal energy. Therefore, the correct pair of students are Hazel and Connor (option d).

feel the inside of your elbow as you lift a book. you should feel a strong cord. what is this? what does it do?
We feel the inside of the elbow as we lift a book. We should feel a strong cord. This cord is known as Oblique cord.
What is the Oblique cord?The oblique cord is a ligament which is present between the ulnar and radius bones in the forearm region near the elbow. Oblique cord takes the form of a small, flattened band, which is extending downward and lateralward, from the lateral side of the ulnar bone tuberosity at the base of the coronoid process to the radius of a little below the radial tuberosity. The fibers in this cord runs in the opposite direction to those of the Interosseous membrane of the forearm region of the hand.
The oblique cord may simply be defined as an additional tie which is between the radius and ulna of the hand which is aiding other soft tissue structures such as the annular ligament and interosseous membrane. Additionally, the oblique cord may also prevent the anterior shearing of the proximal radius under the extreme compressive loads.

What is the respiratory system?
The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system serves a variety of purposes. In addition to assisting with inhalation and exhalation, it:
Enables you to speak and smell.Raises the temperature of the air to that of your body and adds moisture to it to the proper degree of humidity.Provides your body's cells with oxygen.When you exhale, waste gases from your body, including carbon dioxide, are removed.Shields your airways from irritants and dangerous chemicals.
