Answer: The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood. brainliest?
Explanation:
Answer: False
Explanation:
Ticks are the external parasites which survive by feeding the blood of the birds, reptiles, amphibians and mammals. Various species of the ticks are distributed world wide. They colonize and live in the countries with warm and humid climatic conditions. The moisture help them to undergo metamorphosis. There are many species in the families of lxodidae (hard ticks) and Argasidae (soft ticks) that are active parasites and are capable of causing diseases in humans.
Answer:
plants make food with the help of sunlight, water n air is called photosynthesis
Explanation:
In humans gene flow usually comes about through the actual migration of human populations, either voluntary or forced. Although gene flow does not change allele frequencies for a species as a whole, it can alter allele frequencies in local populations.
Hopefully this helps.
Water diffuses from the lumen into the interstitial space during the reabsorption of water in the proximal convoluted tubule due to an increase in the interstitium's osmolarity.
Reabsorption is the process by which water and solutes from the PCT are injected into the blood. From the proximal convoluted tubule, the solutes and water go to the interstitium before entering the peritubular capillaries. The majority of the solutes and 99 percent of the water filtered by the nephron must be reabsorbed; all of these chemicals were "absorbed" in the digestive tract. The peritubular and vasa recta capillaries return reabsorbed fluids and chemicals to the circulation.
