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.

On the Structure of Compact Bone, the order of labelling are:

The photomicrograph shows a cross-section of a Haversian system, which is the basic unit of compact bone. The Haversian system consists of a central canal surrounded by concentric layers of bone called lamellae.

The osteocytes are located in lacunae that are arranged in rows along the Haversian canal. The canaliculi connect the lacunae to each other and to the Haversian canal. The central canal contains blood vessels and nerves that supply the osteocytes. The compact bone is arranged in columns called osteons.

Answer: The correct answer is:

It redistributes heat from the poles to the equator.

Explanation:

The ocean conveyor belt, also known as the global ocean conveyor or thermohaline circulation, is a complex system of ocean currents that circulates water throughout the world's oceans. This system plays a critical role in regulating Earth's climate, as it helps distribute heat from the tropics towards the poles and vice versa.

The ocean conveyor belt works by carrying warm, salty water from the tropics towards the poles, where it cools and becomes denser, eventually sinking and flowing back towards the equator as cold water. This process helps redistribute heat from warmer to cooler regions, which helps to moderate the climate in these areas.

The ocean conveyor belt also has an impact on regional climate by influencing the distribution of precipitation. In areas where warm water from the tropics is carried towards the poles, it can increase evaporation and lead to greater rainfall. Conversely, in regions where cold water is carried towards the equator, it can lead to reduced precipitation.

Overall, the ocean conveyor belt is an important part of Earth's climate system, and understanding its functioning is crucial for predicting and mitigating the impacts of climate change.

Answer:

well it keeps the cell together and protects it too

Explanation:

A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

When a person breathes in, the diaphragm contracts and the lungs expand, creating a vacuum that draws air into the lungs. The air is then circulated through the lungs, where oxygen is absorbed and carbon dioxide is released.

The diaphragm is a vital muscle in inhaling (breath-in) and exhaling, separates the chest cavity from the abdominal cavity.

When the diaphragm contracts, it flattens and moves down. This increases the space in the chest cavity, which causes the lungs to expand. The lungs are elastic, so they expand when the space around them increases.

• Community,, which includes the populations of different species that live in the same area.

• Ecosystem,, the living and not living elements in an area.

• Biomes, are big regions characterized by their climate, flora, fauna, and soil type.

• Biosphere,, all the parts of Earth where life is found.

Explanation:

Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.  

Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.

In the case of Streptomyces griseus, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.

Species change gradually and consistenly over a very long period of time. This is known as species adaptation. Thus, the correct option is D.

Species do not undergo drastic changes over a short period of time, rather it is a gradual change which occurs. These changes accumulate over a long period of time.

The changes are a result of modifications in the phenotype due to the mutations in the genotype. These mutations occur for better adaptation to the changing environment for the survival of the species.
