The answer would be skeletal markers and DNA analysis.
Skeletal markers are often used to identify the biological gender of skeletal remains. The most commonly used skeletal markers can be observed in the skull and in the pelvic bone.However, the accuracy of his method is limited to adults only the differences between male and female skeletal markers usually become visibly only after maturation.
DNA analysis is more widely uses nowadays because with the technology of today, laboratories can now detect and X and Y chromosome-specific sequences, which help them identify the biological gender.
Answer:
They contain protein fibres that can contract when energy is available, making the cells shorter.
The purpose of the digestive system is to break down food into simple molecules that the cells of the body can use.
Food is broken down into its simplest units called monomers. Proteins are broken down into amino acids, fats are broken down into fatty acids and glycerol while carbohydrates are broken down into glucose units.
Glucose is taken in by the cells of the body and through the process of cellular respiration is used to produce the ATP, the form of energy that cells use. Cellular respiration is the process by which cells use glucose to produce energy to power their functions.
The most direct way to different types of epithelium tissue is by the number of cell layers and by the shape<span> of the cells. As for the layers, they can be simple, if there is only one layer of cells, or stratified, if there is more than one layer of cells. Related to the shape of the cells it can be a squamous epithelium, a cuboid epithelium, a columnar epithelium, or transitional when the cell can adopt different shapes so that the epithelium can be stretched.</span>
