How might population density be related to the amount of damage caused by an earthquake?
Answer:
Population density (rural or urban area). The more densely populated an area, the more likely there are to be deaths and casualties. A severe earthquake at rush hour in a densely populated urban area could have devastating effects.
Explanation:
An average of 3.5 million people are affected by earthquakes every year. Earthquakes usually cause severe damage to urban centres, resulting in the loss of life and damage to homes and other infrastructure. Earthquakes sometimes trigger tsunamis, landslides and occasionally volcanic activity.

Answer:
adhesion
Explanation:
The term used to describe the attraction of water molecules to other molecules is referred to as adhesion.
Generally, adhesion or adhesive forces is a term used to describe the force of attraction between molecules of different substances. This is as opposed to cohesion or cohesive forces which refers to the force of attraction between the molecules of the same substance.
Hence, when molecules of water attract or stick to other molecules, the force at play is an adhesive force or simply adhesion.

Which of these statements is best illustrated by this diagram?
Answer:it’s D
Explanation:
Because plants take carbon dioxide
The statement that is best illustrated by the diagram is that plants can take in carbon dioxide from air or water. The correct option is D.
What is the carbon cycle?The carbon cycle refers to the biogeochemical processes that keep the earth's and the atmosphere's carbon levels stable and in balance.
The pathways show how the carbon compound is used in various processes and sources while maintaining its natural composition. The cycle's primary goal is to maintain a balance of carbon in the ecosystem's biotic and abiotic components.
Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.
Therefore, the correct option is D, plant can take in carbon dioxide from air or water.

The properties of a substance are not affected by chemical reactions.
A) true
B) false
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Explanation:
The statement "the properties of a substance are not affected by chemical reactions" is false.
What are physical and chemical properties?A substance's physical property is a quality that can be seen or quantified without affecting the substance's identity. Color, density, hardness, and melting and boiling points are examples of physical qualities.
A quality of matter that is unrelated to a change in its chemical makeup is called a physical property. Density, color, hardness, melting and boiling points and electrical conductivity are a few common examples of physical qualities.
Chemical changes result in new compounds with different properties from the original ones, as well as new particles and maybe altered particle numbers.
Therefore, the statement is false.

Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
Which explanation accurately describes how matter is transformed within the process of photosynthesis?
A) In the light reactions, carbohydrates release hydrogen atoms and form carbon dioxide. The hydrogen atoms join with oxygen to form water molecules in the Calvin cycle.
B) In the Calvin cycle, carbohydrates release hydrogen atoms and form carbon dioxide. The hydrogen atoms join with oxygen to form water molecules in the light reactions.
C) The hydrogen and oxygen atoms of water are split in the Calvin cycle, and oxygen is released. In the light reactions, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Answer:
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Explanation:
Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.
Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.
Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

The purpose of photosynthesis is to Release chemical energy in the form of ATP for humans Release chemical energy in the form of ATP for humans Convert solar energy to chemical energy stored in sugar Convert solar energy to chemical energy stored in sugar Build proteins in plants
Answer:
Convert solar energy to chemical energy stored in sugar
Explanation:
Photosynthesis is the process whereby green plants manufacture their food, which is in the form of a sugar (glucose). The photosynthetic process, generally, combines carbon dioxide (CO2) and water (H2O) in the presence of sunlight, which provides energy used.
The sugar (glucose) produced stores chemical energy in its chemical bonds. In a nutshell, photosynthesis converts SOLAR ENERGY (from sun) into CHEMICAL ENERGY (in glucose), which is the purpose of the process for organisms that undergo it.
