No, ice is not a macromolecule. Ice is a solid form of water, which is a simple compound made up of two hydrogen atoms bonded to one oxygen atom. Macromolecules are large molecules made up of smaller subunits called monomers.

1. Discovery of penicillin by Alexander Fleming in 1928.
2. Development of the theory of evolution by natural selection by Charles Darwin in 1859.
3. Splitting of the atom by Ernest Rutherford in 1917.
4. Invention of the telephone by Alexander Graham Bell in 1876.

Vitamin D is produced in the skin through a reaction to sunlight. Ultraviolet B (UVB) radiation converts a form of cholesterol in the skin into vitamin D3, which is then processed by the liver and kidneys to become an active form of vitamin D that the body can use.

No, cobalt chloride paper and pH paper are not the same. Cobalt chloride paper is used to test for the presence of water, while pH paper is used to test the acidity or alkalinity of a solution by measuring its pH level.

A dipeptide is a type of biomolecule formed by the condensation of two amino acids linked by a peptide bond. It is a small unit of a protein molecule.

Carbohydrates are macronutrients that serve as the primary source of energy for the body. They are composed of sugar molecules and are found in foods like fruits, vegetables, grains, and dairy products. Carbohydrates can be classified as simple (sugars) or complex (starches and fibers).

If a subject's brain is showing a predominance of beta waves during a sleep experiment, it suggests that the subject is likely awake or in a state of alertness rather than being asleep. Beta waves are associated with active thinking, problem-solving, and alertness, characteristics not typically observed during sleep.

Dr. Felicidad E. Anzaldo is a Filipino doctor specializing in obstetrics and gynecology. She is known for her expertise in women's health issues and has provided medical care and education to many patients in the Philippines.

A deproteinizer is used to remove proteins from a sample, such as DNA or RNA extraction, by precipitating the proteins out of solution. This helps to purify the desired molecule and remove any interfering substances before further analysis.

is specific for starch molecules due to its complementary active site that can bind to starch but not proteins. This specificity allows salivary amylase to break down starch into simpler sugars, such as maltose, through hydrolysis reactions but does not have any catalytic activity on proteins.

Fe Del Mundo is one of the most famous Filipino scientists. She was a pioneering pediatrician who founded the first pediatric hospital in the Philippines and received numerous awards for her work in the field of child healthcare.

Vinegar is not a good source of vitamin C. It is mainly composed of acetic acid and does not provide significant amounts of vitamin C. It is best to obtain vitamin C from fruits and vegetables like oranges, strawberries, and bell peppers.

Population biology became firmly established as a major subdivision of biological studies in the 1970s. Central to this field is evolutionary biology, in which the contributions of Charles Darwin have been fully appreciated after a long period of neglect. Population genetics, the study of gene changes in populations, and ecology, the study of populations in their natural habitats, have been established subject areas since the 1930s. These two fields were combined in the 1960s to form a rapidly developing new discipline often called, simply, population biology. Closely associated is a new development in animal-behavior studies called sociobiology, which focuses on the genetic contribution to social interactions among animal populations.

Cellulose is not a vitamin. It is a type of carbohydrate that provides structural support to plants and is not considered essential for human nutrition.

During interphase, the three main events that occur are: cell growth, DNA replication, and preparation for cell division. Cell growth involves the synthesis of proteins and organelles needed for the cell's activities. DNA replication ensures that each daughter cell will receive a complete set of genetic information. The cell also prepares for division by organizing its structures and getting ready to replicate its DNA.

their interactions and transformations. It deals with the properties of matter and the changes it undergoes during chemical reactions. Chemistry is divided into several branches such as organic, inorganic, physical, analytical, and biochemistry.

No, epidermal cheek cells do not contain pigments. Pigments such as melanin are produced by melanocytes located in the basal layer of the epidermis and transferred to surrounding keratinocytes, providing skin coloration. Cheek cells mainly consist of epithelial cells that do not contain melanin.

Micro meaning extremely small and scope meaning to view. It has the ability to observe matter organisms and what have you, that we humans are unable to observe with the naked eye. It is useful because it helps medically, scientifically and which every way.

Vitamins are essential nutrients that play key roles in various bodily functions, such as supporting immune function, promoting growth and development, and aiding in energy production. They are crucial for overall health and well-being, and deficiencies can lead to various health problems. However, it is important to consume them in appropriate amounts as excessive intake can also have negative effects on health.

The products of protein hydrolysis are amino acids. Proteins are broken down into their individual amino acid components through the process of hydrolysis, which involves the cleavage of peptide bonds. Amino acids are the building blocks of proteins and are essential for various biological functions in the body.

Fruits, vegetables, whole grains, nuts, seeds, legumes, dairy products, and lean proteins are good sources of vitamins and minerals. Including a variety of these foods in your diet can help ensure you are getting a balanced intake of essential nutrients.

== == Vitamin A (retinol) essential in the formation and maintenance of healthy teeth, skeletal and soft tissue, mucous membranes, and skin. Vitamin A is essential to your body. It enables you to have good eyesight. Vitamin A is found in lots of vegetables. Ex: Carrots, Cucumbers, Broccoli, Peas

The transportation sector consumes the majority of the nation's petroleum, accounting for around 60% of total petroleum consumption in the United States. This includes gasoline used by cars, diesel for trucks, and jet fuel for airplanes.
