explain the interaction between geological events, human population, and the environment
The relationship between the environment, human population and geological events is complex and multidimensional. While human activities can also have significant effects on geological processes, geological events such as earthquakes, volcanic eruptions and climate change can have significant effects on the environment and human populations.
What is an Environment?The conditions and forces that surround an organism, population or community are called its environment. It includes all elements of the Earth, both living and non-living, such as the atmosphere, hydrosphere, lithosphere, and biosphere.
The environment is a complex system that living things interact with and influence how they survive, develop and thrive. This includes biological elements such as plants, animals, microorganisms and their interactions, as well as physical elements such as temperature, light, water, soil, wind and topography.
Therefore, the relationship between the environment, human population and geological events is complex and multidimensional.

Explanation:
Which of the following best describes an antigen?
B. A recognition molecule on the surface of the cells.
What is antigen?An antigen is a substance that is capable of triggering an immune response in the body. It is typically a foreign substance, such as a pathogen (e.g. a virus or bacterium), a toxin, or a non-infectious particle (e.g. pollen or dust), that is recognized by the immune system as being foreign and potentially harmful.
When an antigen enters the body, it is recognized by immune cells called B cells and T cells, which produce proteins called antibodies to help neutralize and remove the antigen. The antigen-antibody interaction is a key part of the body's immune response and helps to protect us against infectious diseases.
Antigens can also be present on the surface of our own cells, such as cancer cells or transplanted organs, and can trigger an immune response if they are recognized as foreign by the immune system.
Overall, antigens are important components of the body's immune system and play a critical role in protecting us against infectious diseases and other threats.

We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.
