what is pepsinogen and how does it helps in digestion of protein ?
Answer:
Pepsinogen is a powerful and abundant protein digestive enzyme secreted by the gastric chief cells as a proenzyme and then converted by gastric acid in the gastric lumen to the active enzyme pepsin.
Explanation:
The role of pepsin and its precursor in protein digestion was first described in the 19th century.

Sam has a mutation in a gene that affects the function of a transfer RNA (tRNA). Human cells have 20 different types of tRNAs, and each adds a different amino acid to growing peptide chains, which form proteins. Based on what you know so far, would you expect this mutation to affect all proteins produced in Sam's cells? Explain your reasoning.
Answer:
No
Explanation:
The mutation is not expected to affect all the proteins produced in Sam's cells because each protein has a different structure and functions. Proteins are polymers of amino acids and the component amino acid for each protein diffesr. Hence only the proteins whose constituent amino acids include the amino acid being carried by the mutated tRNA would be affected. Others whose constituent amino acids do not include the amino acid being carried by the mutated tRNA would function normally.
which is true in a covalent bond
Answer: A chemical bond that involves electron pairs being shared between atoms is called a covalent bond.
precautions for soil sampling
Answer:
Explanation:
When collecting samples, avoid small areas where the soil conditions are obviously different from those in the rest of the field—for example, wet spots, old manure and urine spots, places where wood piles have been burned, severely eroded areas, old building sites, fencerows, spoil banks, and burn-row areas.

write a summary about the cell theory
Answer:
Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:
all organisms are made up of one or more cells,
all the life functions of an organism occur within cells,
all cells come from preexisting cells.
Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:
all known living things are made up of one or more cells,
all living cells arise from pre-existing cells by division,
the cell is the fundamental unit of structure and function in all living organisms,
the activity of an organism depends on the total activity of independent cells,
energy flow (metabolism and biochemistry) occurs within cells,
cells contain hereditary information (DNA) which is passed from cell to cell during cell division,
all cells are basically the same in chemical composition in organisms of similar species.
The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Later, Rudolf Virchow made significant contributions to this theory.
Why is it important to study cell theory?Cell theory is critical for understanding biology because cells are the foundation of all life. We can have unicellular organisms such as bacteria and yeasts. cell division, the division of a cell from one to two to four, is the foundation of all living things' growth and development.According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

The California current is a cold current that runs along the West Coast of the United States. How would this affect the weather of San Francisco which is on the coast?
Answer:
The weather of San Francisco gets colder with the California current.
Explanation:
The template California´s current oceanic ecosystem is one of the most productive and diverse in the world.
The California current flows from the northern latitude, running along the occidental coast of North America, forward to the South.
The cold current makes coasts colder than the east coasts. When winds blow from the sea, they bring cold air over the land because the cold California current lowers the air temperature. Even more, winds coming from the northwest originate upwellings that bring colder water from the bottom, lowering, even more, the current temperature.
Thus the temperature of California’s coastal cities, such as San Francisco, is relatively cool.

type of mutation causes sickle cell anemia?
Answer:
Sickle cell anemia is the result of a point mutation in the hemoglobin gene. Sickle cell hemoglobin (HbS) causes red blood cells to form a sickle shape. People who inherit one sickle cell gene and one normal gene have sickle cell trait.
