Answer:
D) It would contain less nitrogen.
Explanation:
In an investigation of the cycling of environmental gases, a student placed water and bromthymol blue in each of four test tubes as shown in the diagrams below. No additional items were placed in tube 1, a snail was placed in tube 2, an aquatic plant (elodea) was placed in tube 3, and both a snail and an elodea were placed in tube 4. The tubes were then stoppered and placed in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.
The dfferent tubes are shown in the picture that I uploaded.
The principal function of thyroxine is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues.
Thyroxine is termed T4. It travels through the blood to the target cells and becomes converted to triiodothyronine or T3.
T3 is the active form of thyroxine. T3 enters the target cell's nucleus binding to genes responsible or involved in the metabolism of sugar in the body. T3 stimulates these genes and in so doing metabolism (conversion of oxygen and calories to energy) is carried out by the cell, which also results in generation of body heat.
Answer:
a.glycolysis d.acetyl CoA b.citric acid cycle e.electron transport chain
Explanation:
Cellular respiration is set of metabolic processes that occur within the cell in order to produce usable energy (ATP) from the nutrients (food). It can be divided into four main stages:
- Glycolysis-anareobic process in which glucose is broken down and it occurs in the cytoplasm. Products of glycolysis are 2 molecules of pyruvate and 2 molecules of ATP.
- Transition- Pyruvate form the glycolysis is transported into the mitochondria, where it is converted to a molecule Acetyl CoA used for further breakdown
- Citric acid cycle or Krebs cycle- aerobic process that occurs in the mitochondria matrix in which 4 molecules of ATP, and NADH are produced
- Electron transport chain-set of reactions that occur within the cristae of mitochondria. NADH and electrons are passed through electron transport chain to result in the production of ATP (32 ATPs for every glucose).
