As per the properties of minerals ,luster,density,streak and hardness refer to the specified properties of minerals respectively.
What are minerals?Minerals are defined as a chemical compound which has a well -defined composition and possesses a specific crystal structure.It occurs naturally in the pure form.
If a compound occurs naturally in different crystal structure then each structure is considered as a different mineral.The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.
Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure.It may also have variable composition which is split into separate species.
Physical properties of minerals include color,streak, luster,specific gravity and cleavage.

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis.
Answer:
The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.
During photosynthesis, water and carbon dioxide in presence of sunlight are converted into glucose and determining product oxygen.
What do you mean by Cellular respiration?Cellular respiration may be defined as the process through which each cell can utilize energy from the glucose molecules broken down.
Being complex process photosynthesis converts light energy into chemical energy. The chlorophyll pigment of green plants captures sunlight and converts water and carbon dioxide into glucose (sugar), an energy compound, and oxygen.
Therefore, during photosynthesis, water and carbon dioxide in presence of sunlight are converted into glucose and determining product oxygen.

In a step by step format, write about the process of the blood flow as it enters the heart until it leaves the heart. It should be at least 150 words.
Answer:
Blood enter the right atrium of the heart via the vena cava (superior and inferior)
The right atrium contracts to push the blood into the right ventricle through the triscupid valve
The contraction of the right ventricle pushes the blood through the pulmonary valve to the pulmonary artery which carries it to the lungs to be oxygenated
After oxygenation, the pulmonary vein brings blood to the left atrium
Contraction of the left atrium pushes the blood through the mitral valve into the left ventricle
The left ventricle contracts to push the blood through the aortic valve, into the aorta, which carries the blood through the body.

CellTissueOrganOrgan systemOrganismWhat is the definition of cell?Cell: The basic unit of life for both plants and animals is the cell, which is capable of carrying out all the fundamental functions of life.
Tissue: Cells that work together to perform a specific function form tissues. In plants, tissues include meristematic, ground, and vascular tissues. In animals, tissues include epithelial, connective, muscular, and nervous tissues.
Organ: Different tissues work together to form organs, which are structures that perform specific functions. Examples of plant organs include leaves, stems, roots, and flowers. Examples of animal organs include the heart, lungs, liver, and kidneys.
Organ system: Organs that work together to perform a particular function form an organ system. Examples of plant organ systems include the root system, shoot system, and reproductive system. Examples of animal organ systems include the circulatory system, respiratory system, digestive system, and nervous system.
Organism: An organism is a complete, individual living entity that is made up of multiple organ systems. Plants and animals are both organisms.
