Temporary changes are the changes in a particular system for just only a specific time.
Explanation:
Temporary changes are those that are irreversible and occur only for a certain period of time after which things are normalized. These are also referred to as temporary stress.
These changes disrupt the homeostasis and can lead to a physiological reaction.
Temporary changes in the physiological system include:
1. An increase or decrease in heartbeats for short period of time
2. Shortness of breath after exercise
3. Flickering or watering of eye due to a foreign object
4. Perspiration due to heat
5. Enlargement of stomach after meal

The density of gas particles in a section of Earth's atmosphere decreases. Which of the following is the most likely explanation for this event?
The air pressure in that section of Earth's atmosphere decreased.
The air pressure in that section of Earth's atmosphere increased.
The total number of gas particles in Earth's atmosphere decreased.
O The total number of gas particles in Earth's atmosphere increased.
Answers
The most likely explanation for the decrease in the density of gas particles in a section of Earth's atmosphere is that the air pressure in that section of the atmosphere decreased.
Density is defined as mass per unit volume. In the case of a gas, density is directly related to the number of gas particles (molecules or atoms) present in a given volume. When the air pressure decreases, it means that there are fewer gas particles exerting force per unit area. As a result, the density of gas particles in that section of the atmosphere decreases.
Air pressure is the force exerted by the gas particles on the walls of the container or the surroundings. It is influenced by several factors, including temperature, altitude, and the presence of other gases. Changes in these factors can cause fluctuations in air pressure. For example, if there is a decrease in temperature, the gas particles lose kinetic energy, which leads to decreased pressure and density.
It is important to note that the total number of gas particles in Earth's atmosphere does not necessarily change significantly over short periods of time. The atmosphere is composed of a vast number of gas molecules, and while there may be variations due to natural processes, such as volcanic eruptions or biological activities, these changes are relatively small compared to the overall composition of the atmosphere.
Therefore, the most likely explanation for the decrease in density of gas particles in a section of Earth's atmosphere is a decrease in air pressure, which can occur due to various factors such as weather systems, changes in altitude, or movement of air masses.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis.
Thus, Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Chlorophyll absorbs energy from blue and red light waves during photosynthesis while reflecting green light waves, giving the appearance of a green plant.
Thus, Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis.

Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:
There is no cartilage but there is epithelium
Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

A student makes a sandwich with several layers of bread and
cheese. Then the student cuts the sandwich and says it models how a fault cut through rock layers after the rock layers formed. Explain how the example of the sandwich relates to relative dating.
Answers
The example of the sandwich exemplifies relative dating as the age of the rocks can be determined by examining the layers.
How is the sandwich related to the rock formation and relative dating?The student's analogy of a sandwich being cut through represents a model of how rock layers can be cut through by faults. Relative dating is the process of determining the age of rocks or geologic events in relation to other rocks or events.
In the sandwich example, each layer of bread and cheese represents a rock layer. Just like how the bread and cheese are stacked on top of each other, rock layers are also stacked on top of each other over time. However, just as the sandwich can be cut through by a knife, rock layers can be cut through by a fault.
When a fault cuts through a rock layer, it displaces the layers and creates a new boundary. Similarly, when the sandwich is cut, the layers are displaced and new boundaries are created. By examining the position of the newly formed boundaries and the relative order of the bread and cheese layers, one can determine the relative age of each layer.

How are the functions of cork and a cuticle similar? How are these features different?
Answers
Cork is a type of tissue that develops in the bark of woody plants and serves to protect the plant from physical damage, disease, and water loss. Cork cells are dead at maturity and have a thick, waterproof cell wall composed of suberin, which helps to prevent water from entering or exiting the plant. The cork layer also helps to regulate temperature and gas exchange in the plant.
Cuticle, on the other hand, is a waxy layer that covers the leaves, stems, and other aerial parts of plants. The cuticle helps to prevent water loss by creating a barrier that limits the movement of water out of the plant. It also helps to protect the plant from damage and disease by providing a physical barrier against pathogens and pests. The cuticle can also reflect excess light, which helps to reduce the amount of light energy that is absorbed by the plant.

Answers
Answer:
it was
Explanation:
The correct answer is B. Cellular respiration supplies energy to cells, but photosynthesis does not.
Which statement is correct?Photosynthesis and cellular respiration are two distinct processes that occur in living organisms, particularly plants. Here's a brief explanation of each process:
Photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. It occurs in the chloroplasts of plant cells. The process involves the absorption of carbon dioxide (CO2) and the release of oxygen (O2) as a byproduct. Photosynthesis is responsible for converting solar energy into stored chemical energy.
Cellular respiration: Cellular respiration is the process by which cells break down glucose and other organic molecules to release energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells, including plant cells. During cellular respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced as waste products. This process provides energy for various cellular activities.
Given the descriptions above, option B is the correct statement. Cellular respiration supplies energy to cells through the breakdown of glucose, while photosynthesis is the process that converts light energy into chemical energy and produces glucose.

Therefore:
The medium should not include galactose when selecting for gal⁺.
