What are two most important alkali metals?
The two most important alkali metals would be sodium and potassium.
What are the two most important things the blood carries to the body cells and the waste gas that blood carries away from these cells?
The two most important things carried to body cells by blood are oxygen and nutrients, while the waste gas carried away from cells is carbon dioxide. Oxygen and nutrients are essential for cell function and energy production, while carbon dioxide is a waste product of cellular metabolism that needs to be removed from the body.
Why is it important sex cells have half the number of chromosomesas body cells?
This is important because two sex cells become fertilized and join together to form the new organism. If sex cells had the same number of chromosomes as body cells, then offspring would have twice as many chromosomes as a normal animal would.
What are the two main type of cells?
The two main types of cells are eukaryotic cells, which have a defined nucleus and organelles, and prokaryotic cells, which do not have a defined nucleus and organelles. Eukaryotic cells are found in plants, animals, fungi, and protists, while prokaryotic cells are found in bacteria and archaea.
How many types of cells does blood contain?
The answer varies on how specific one wishes to go. Most generally, there exist 3 large groups of cells in the blood: erythrocytes, leukocytes, and thrombocytes. Erythrocytes are simply red blood cells that are responsible for oxygen carrying. Thrombocytes, better known as platelets, are small fragments of a huge myeloid derived cell known as a megakaryocyte. These are responsible for clotting. Leukocytes break down into two major categories: Granulocytes (so named as they contain staining granules in microscopy) and agranulocytes (cells that don't have these) Granulocytes then break into three cell types: Neutrophils (phatocytose bacteria/fungi), eosinophils (attack parasites), and basophils (involved in inflammation (allergenic/non-allergenic)). Agranulocytes break down into three major categories: monocytes (macrophages), lymphocytes, and dendritic cells. Monocytes are a class of phagocytic cell. They are however most famous for being the ancestors of the macrophage, the most famous phagocytic cell in the innate immune response. Dendritic cells are phagocytic cells and are the most famous antigen presenting cell (APC). However, it is to be noted that only immature dendritic cells are found in blood; active ones only exist in tissue. Lymphocytes are subdivided into B-cell (humoral immune response by antibody release) and T-cells (cell-mediated response), which themselves break down into helper T-cells (B-cell activation) and cytotoxic T cells (apoptosis of abnormal cells). All of these can be further subdivded into active and memory versions. So "number of different cellular elements in blood" is a vague question at best, as there are too many methods of classification and differentiation to result in an appropriate answer.
What is the most important type white blood cell?
they are all important but the main two are T and B cells
List two lines of nonspecific defense with examples of each?
External defenses - Includes skin and mucous membranes. Internal defenses - Includes phagocytic cells, inflammatory responses, and antimicrobial proteins.
What are two important ways that muscle cells differ from cheek cells?
It has more mitochondria.
What is the most important product of glycolysis?
Glycolysis is the process of breaking down glucose through the actions of enzymes. Its most important product is ATP, which is the energy-currency of the cell.
List two lines of nonspecific defense mechanisms with examples of each?
First of all, you might want to spell DEFENSE correctly.
What are two most important alkali metals?
The two most important alkali metals would be sodium and potassium.
How is iron stores and transported in the body?
Iron taken in excess is stored in two forms ferritin and hemosiderin. Iron that is not used for erythropoiesis is stored in the mononuclear phagocytic system (MPS) or the reticloendothelial (RE) cells of the bone marrow, liver, and spleen. The body transports iron in hemoglobin which is the substance in the red blood cells which binds to oxygen to transport to the whole body.
What are some important things about the reproduction of the plant cells?
Plant cells reproduce through mitosis, where the cell divides to create two identical daughter cells. Plant cells also have specialized structures called plastids, which contain chlorophyll and are responsible for photosynthesis. Sexual reproduction in plants involves the formation of gametes through meiosis, leading to genetic diversity in offspring. Additionally, plant cells have a cell wall made of cellulose, which provides structure and support during cell division.
What are the two different kinds of animal cells?
The two main types of animal cells are somatic cells and germ cells. Somatic cells form the tissues, organs, and other parts of the organism, while germ cells are involved in reproduction and pass genetic information to the next generation.
What is two reason why cell theory is important?
it's the basic unit of all living things, and all cells come from other cells
Why is it important that the cells DNA is duplicating before cell division?
So that the two new cells that are going to be made have an equal amount of chromosomes in them.
What are the two most important things the blood carries to the body cells and the waste gas that blood carries away from these cells?
The two most important things carried to body cells by blood are oxygen and nutrients, while the waste gas carried away from cells is carbon dioxide. Oxygen and nutrients are essential for cell function and energy production, while carbon dioxide is a waste product of cellular metabolism that needs to be removed from the body.
