Answer:
photosynthesis process uses the sun's energy to combine carbon dioxide and water to form glucose, a sugar. Carbon dioxide enters plants through tiny pores in the bottoms of leaves or by diffusion through cell membranes in the case of algae and protists.
Urine Specimen must be chilled if testing will not be performed immediately.
<h3>What is Urine?</h3>
Urine is a liquid byproduct of human and many other animal metabolism. Urine travels from the kidneys to the urinary bladder via the ureters. Urine is discharged from the body through the urethra as a result of urination.
Many by-products of cellular metabolism, such as urea, uric acid, and creatinine, are nitrogen-rich and must be removed from the bloodstream. These by-products are excreted from the body through urination, which is the major way for excreting water-soluble compounds. A urinalysis can identify nitrogenous wastes in mammals.

Answer:The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
Answer: The given statement is true.
Sun is the ultimate source for energy on the Earth. It is the natural and renewable source of energy on earth as it can easily be renewed and never run off. All living organisms which are present on earth are dependent on food for survival. For this, they become part of the food chain which provides them energy in the form of food. Food chain begins with plants as they are the primary producers in the food chain. They get energy for preparing food from sunlight in the form of light energy.
Moreover, the life forms which existed millions of years ago were dependent on sun for energy. The dead remains of these life forms have provided the non renewable sources of energy like fossil fuels on earth.
Thus, the sun is considered as the ultimate source of energy on the Earth.
