Answer:
The correct answer is: d. loss of blood pressure and loss of oxygen-carrying capacity.
Explanation:
- Blood is a liquid connective tissue which is the major component responsible for transporting nutrients and oxygen to all the cells in the body and for removing carbon dioxide and metabolic wastes from all the cells of the body.
- When there is excessive blood loss, the total volume of blood in the body decreases far below normal. As a result of this the blood pressure (pressure applied by the blood on the walls of the arteries) decreases.
- This is because the rate at which blood is lost is far more than the rate at which it is produced.
- The decrease in blood pressure prevents the blood from travelling easily against the gravity, hence it is unable to reach all the regions of the body, thereby depriving many cells of nutrients and oxygen. The waste products are also not efficiently collected from these cells. This causes the cells in the deprived regions to die.
- Blood carries the most important component required for respiration and metabolism, that is oxygen, in association with haemoglobin molecules. Excessive blood loss causes loss of haemoglobin as well. This can cause reduction in the oxygen-carrying capacity of blood. Hence the cells of the body are unable to carry out metabolic activities properly due to the dearth of oxygen. This causes the death of cells.
- Excessive death of cells causes tissues to become non-functional and that can cause organ failure. Multiple organ failure can pose severe threat to life.
Answer:
When taking out of natural habitat and put into an unfamiliar habitat several adaptations and behavioral changes can occur; however, it would depend on circumstances. Compare and contrast.
Explanation:
If you are provided with adequate medical, shelter, food, water, and access to leave whenever to seek these some of these luxury's than adaptation and behavioral changes would be the lesser. However, granted that you just go there with nothing you would would have to fight for survival - to live peacefully. You would have to adapt to your surroundings by learning to camouflage to avoid predators, you would have to learn to hunt for food and water, adapt to the sounds because of your sensory system will be off, you would have to be able build a shelter and learn ways to adapt to the climate. Eventually your body will adapt to withstand the many diseases, the food, and climate of the amazon rain-forest.
Behavioral changes of aggressiveness and alertness can be seen at an elevated level with having to prey and avoid predators -Darwin's survival of the fittest. The behavioral changes go along side with having to shift foraging patterns to avoid predators. Environmental changes can impair sensory systems or interfere with the physiological process which can weaken the ability of survival it can either make you paranoid or you can adapt; thus, changing your behavioral response.

Answer:
DNA molecular weight standard controls, also known as DNA ladders
Explanation:
A DNA ladder is a molecular-weight size marker used to identify the size of the PCR products in a gel electrophoresis. The DNA ladder consists of a solution containing double-stranded DNA fragments with different molecular weights including, among others, 50 base pairs (bp), 100 bp, 1000 bp and 3000 bp DNA fragments. The concentration of each DNA fragment in the DNA ladder must be sufficiently high to be visualized on the electrophoresis gel.
Answer: Boa constrictor is a carnivore (meat-eater).
Explanation: While they are young, boa constrictors eat smaller prey, like rats, mice and squirrels.
The distinction between protostomes and deuterostomes is based on differences in their embryological development. Protostomes develop their oral end from their first developmental opening, while deuterostomes have their oral end develop from the second opening on the dorsal surface.
