They use DNA sequencing to identify species via genetic differences.
What is the significance of DNA sequencing?
The four chemical "bases" that make up the DNA molecule must be identified in the correct order in order to sequence DNA. The sequence provides information to scientists about the type of genetic data that is contained in a certain DNA segment.
For instance, scientists can utilize sequence data to identify the DNA segments that contain genes and the segments that carry regulatory instructions that switch genes on and off. Furthermore, and this is crucial, sequencing data might point out variations in a gene that might be harmful.
Large DNA lengths, 1 million bases or more, from various individuals can now be compared swiftly and affordably by researchers. Such comparisons can reveal a wealth of information regarding how inheritance affects illness susceptibility and how the body reacts to environmental factors. The potential for diagnostics and treatments is also greatly increased by the faster and more affordable genome sequencing.
The biology of development and evolution can also be better understood by comparing the genomic sequences of other animals and species, like yeast and chimpanzees.

In the context of joint mobilization techniques, for what are inferior femoral glides at 90 degrees of hip flexion used?
Hip Inferior Glide is used to improve hip flexion. The technique is performed in supine with the hip flexed to 90°.
This technique can be used for decreasing muscle spasm or pain, and is also useful to increase accessory joint movement for flexion and abduction movements.
By performing the therapy the clinician’s hands can be clasped at the superior proximal femur or a mobilization strap can be used to enhance grip and reduce sliding on subject's skin. The clinician can simply lean back to impart an inferior force to the femur with a counterforce of the shoulder on the distal femur.

Glycolysis requires an initial energy investment, which allows for the production of relatively larger quantities of ATP during Substrate-level phosphorylation
The process of glycolysis starts with a single glucose molecule, which has a six-carbon ring structure, and finishes with two molecules of pyruvate, a three-carbon sugar. Two separate phases of glycolysis exist. Energy is utilized to alter the first step of the glycolysis process so that the six-carbon sugar molecule can divide equally into two three-carbon pyruvate molecules. ATP and nicotinamide-adenine dinucleotide (NADH) are created during the second phase of glycolysis.Substrate-level phosphorylation is the direct transfer of a high-energy phosphate group from a phosphorylated intermediate metabolic molecule in an exergonic catabolic pathway, which results in the generation of ATP from ADP.learn more about glycolysis here:

The reduction of blood volume occurs following severe dehydration and hemorrhage; however, although dehydration results in an increase in hematocrit, immediately following hemorrhage hematocrit is unchanged. Explain this difference.
During bleeding, both formed elements (platelets, white blood cells, red blood cells) and plasma are lost from the circulatory system. They are lost proportionally, so initially there is no change in hematocrit.
Hematocrit is the percentage of the blood volume made up of elements (Hct = cell volume/blood volume). During dehydration, only water and electrolytes are lost, and the number of cells remains constant - the same number of cells in a smaller volume leads to an increase in hematocrit. When the body tries to restore blood volume, the first thing to recirculate is water from the ECF and this increases the amount of water without increasing the amount of red blood cells, so the compensatory mechanism causes the hematocrit to fall.
