Oxygen is taken into the body from the environment, and carbon dioxide is removed from the body and released into the environment. Which
body system is responsible for exchanging gases with the environment? ( point)
A.endocrine
B.circulatory system
C. respiratory system
D. nervous system
Answers
Answer:
The correct answer would be in this case C) respiratory system. It is the main source where the process of gas exchange occurs, taking in oxygen and breathing out carbon dioxide into the rest of our surrounding environment.
The respiratory system is responsible for the exchange of gases with the atmosphere. So the correct option is C.
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.
Therefore the correct option is C.

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?
Answers
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

Which of the following statements is NOT TRUE about photosynthesis and cellular respiration? (B.9B)
Question 19 options:
Both processes require energy
Both processes occur in the mitochondria
The chemical equations for the processes are opposite of each other.
Photosynthesis occurs in plants; cellular respiration occurs in plants and animals.
Answers
Answer:
Both processes require energy cuz respiration produces energy
Explanation:
The statement that is not true is that both processes occur in mitochondria as photosynthesis happens in chloroplasts. So the correct option is B.
What is cellular respiration in plants?While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots respire slowly.
Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.
Plants produce glucose molecules during this process of cellular respiration by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.
Therefore the correct option is B.

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)
Answers
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.

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.
Answers
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.
Answers
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).
