The amount of different gases varies in environment. Just like oxygen and carbon dioxide, Water vapor also have different amounts in inhaled and exhaled air.
What is breathing?Breathing is the process of inhaling oxygen and removing carbon dioxide.
During breathing amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide,while during exhalation 16.4% of oxygen and 4.4% of carbon dioxide is there.
The reason behind such variation is that cells use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct.
Water vapor is also inhaled and exhaled in different amounts just like oxygen and carbon dioxide.
Thus, the correct option is C.

15. Choose the best answer. What causes chromosomal disorders?
Answer:
What i got was Point Mutations
But people all so arguw that Adaptation is it two
Answer:
Technically the first 3
Explanation:
Genes are segments of DNA that have code for a specific protein that functions in one or more types of cells. Chromosomes are structures in cells that contain a person's Genes. Genetic disorders can be caused by a mutation in one gene which is called a monogenic disorder.
The fourth one about traits is tricky to decipher as there are about 25 to 35 thousand genes in one cell that carry information inherited from your parents that determine your traits. If Chemical traits could be explained further in detail, this might be an option
butIi would say it would say point mutations

30. The Asian country Georgia had a 2008 birthrate
of 11 and a death rate of 10. What was the PGR
of Georgia in 2008?
A. 1 percent
C. 1.1 percent
B. 0.11 percent
D. 11 percent
Answer: 1 percent
Explanation: Natural decrease occurs when death rate is greater than birth rate. This means that more deaths occur in a population than babies are born so population numbers decline. For several important causes of death, rising incomes and a variety of social programs have accompanied significant reductions in mortality. Higher incomes make possible the use of expensive medical technology and are correlated with less smoking than lower incomes.
Given the unit,identify the measurable property.
P= pressure exerted by the gas is atm, and V= total volume occupied by the gas is L.
What are measurable properties?Another characteristic of gas that can be measured is pressure. We are aware that the force a gas exerts on the container's walls per unit area in all directions is known as pressure. Additionally, any gas exerts pressure due to the kinetic energy of its molecules.
T= temperature of the gas is K
n= number of moles of the gas is mol
m³= The metric unit for measuring volume is the liter (L), and the cubic meter (m3)
pascal = newton per meter square.
Therefore, T stands for temperature, which is the unit used to express how hot something is. Degrees Fahrenheit (°F), degrees Celsius (°C), and Kelvin (K).

Mutations in which of the following genes lead to transformations in the identity of entire body parts?
A) morphogens
B) segmentation genes
C) egg-polarity genes
D) homeotic genes
E) inducers
Answer:
D) homeotic genes
Explanation:
Every organism has a unique body pattern. Although specialized body structures, such as arms and legs, may be similar in makeup (both are made of muscle and bone), their shapes and details are different. While an embryo grows, arms and legs develop differently due to the actions of homeotic genes, which specify how structures develop in different segments of the body. A mutation in these genes would lead to drastic changes in body morphology

Which of the following best describes prokaryotes and eukaryotes?
O Prokaryotes have a nucleus and eukaryotes do not.
O Prokaryotes do not have a nucleus, eukaryotes have a nucleus.
Both have membrane-bound structures
Prokaryotes have membrane-bound structures and eukaryotes have free floating organelles
Answer:
Prokaryotes do not have a nucleus, eukaryotes have a nucleus.
Explanation:
The prokaryote cells do not have a nucleus whereas eukaryotic cells have distinct a nucleus.
Eukaryotes are creatures made up of cells with membrane-bound organelles and a nucleus that contains DNA in the manner of chromosomes. Thus, option B is correct.
What are eukaryotes and prokaryotes?Prokaryotes and eukaryotes are the two classes into which all living things may be divided based on the basic makeup of their cells.
Prokaryotes are creatures consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryotes' DNA is not contained within a nucleus.
Eukaryotic organisms can have several cells or only one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.
Therefore, Prokaryotes do not have a nucleus, eukaryotes have a nucleus.

Venn diagrams are used for comparing and contrasting topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. This Venn diagram is comparing longitudinal waves and transverse waves.
Where is the error in this Venn diagram?
“Parallel” and “Perpendicular” are switched.
The spring descriptions of motion are switched.
Particles travel along the wave in longitudinal waves.
Particles move long distances in transverse waves.
Answer:
The commonality between the two waves is that they; “Carry energy” and “Follow a pattern”.
A wave is defined as a disturbance along a medium that transfers energy. Mechanical waves require a material medium for propagation while electromagnetic waves do not require a material medium fro propagation.
At the center of the Venn diagram, there ought to be something that is common to both of the types of waves and that is the fact that they both “Carry energy” and “Follow a pattern”.
Hence, what is common is that all the waves carry energy.

Answer:
A; Stool culture
Explanation:
Gastroenteritis is an inflammation that affects the small intestine and stomach. Although not related to the flu, it is sometimes called intestinal flu. It is caused by an infection that can be viral, fungal or bacterial, but the most frequent is that the causative agent is a virus. An inflammation is the body's reaction to tissue damage or infection. The affected area becomes red, hot, with an increased blood flow and is often painful.
The stool test is done to confirm the type of infection that is causing gastroenteritis. In the fecal sample, rapid tests for viruses, such as rotavirus or adenovirus, can be performed, as well as bacterial culture, which allows observation and evaluation under the microscope. In the fecal sample it is also possible to perform an immunological examination, which can reveal the eggs of parasites that may be causing the disease. For this reason, we can say that it is likely that the doctor shown in the question above will use the stool test to confirm the diagnosis.

the analogy are are working on comparing viral and replication with the making a product in a factory. In what ways does the analogy not hold true?
The analogy does not hold true for the control of virus multiplying, in the viral replication with the making of product in a factory.
What is viral replication?The development of biological viruses throughout the infection process in the target host cells is known as viral replication. Before viruses replicate, they must first enter the cell. The virus keeps infecting new hosts by producing several copies of its DNA and packaging these copies.
