Answer:
1. Red blood cells: It produces hemoglobin, an oxygen-carrying protein.
2. White blood cells: It produces soluble protein called antibodies.
3. Muscle cell: It produces the muscle protein known as myosin.
Explanation:
The above are some of the specialized cells in multicellular organism. The red blood cell is in charge of carrying oxygen in the body. It contains/produces hemoglobin which is the protein the cell also produces. The hemoglobin also gives the blood cell its red color.
The white blood cell, also known as leukocyte is the component of the blood cell which defends the body against infections. The cell is highly mobile within the body and moves to the site of infection in order to defend it. It produces antibodies that actually defend the body against infections.
The muscle cell are the cells within the human body that help to make the movement of cell to be possible. It produces myosin which also combines with actin, another muscle protein.
The answer is K-selected.
The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent.
Answer:
The skinfold method, the measurement of subcutaneous fat folds, is the most widely adopted field method for the assessment of body fat, especially in children.
It is based on the principle that fat is of a known density and by “summing” measurements of subcutaneous fat thickness across the body, total and regional fat can be estimated.
Skinfold thickness measurements are typically used to rank individuals in terms of relative total “fatness”, or to assess subcutaneous fat at various regions of the body.
Population specific equations are used to derive estimates of percent body fat.
In infancy, it might be the sole tool available for assessing body composition longitudinally as other methods may not be feasible, or may only be suitable for use at body sizes e.g. PEA POD, can only measure infants up to 10kg.
