Answer:
6.7 minutes
Explanation:
In a solid such as rock, the primary wave can travel at 5 km/sec; it would take 400 seconds, or about 6.7 minutes to travel 2,000 km.
Answer:
Mitochondria are famed as the energy factories of eukaryotic cells, the seat of an array of membrane-bound molecular machines synthesizing the ATP that powers many cellular processes.
The correct answer is C. The temperature of the water
Explanation:
In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.
Answer:
All the options are correct regarding hypothalamus.
Explanation:
The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.
This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.
Hypothalamus also has regulated anterior pituitary hormone secretion. Thus it controls the endocrine secretion of pituitary glands.
This plays an important role in hunger and thirst. The feeding habits like the licking of lips, swallowing, and salivating by seeing delicious foods is due to hypothalamic activities.
The behavioral activities of individuals influenced by the hypothalamus. It is worked along with the limbic system of the brain. The behavioral activities include fear, punishment and sexual desire.
Answer:
Electron transport Chain (Oxidative phosphorylation)
Explanation:
Cellular respiration can be defined as the process that involves the breakdown of glucose molecules into CO2 and H2O to generate energy inform of Adenosine Triphosphate (ATP). Also, cellular respiration usually takes place in the cells of an organism by converting biochemical energy present nutrients into Adenosine Triphosphate. Furthermore, it takes place in three stages which includes: glycolysis, TCA cycle and Electron transport (Oxidative phosphorylation). Thus, oxidative phosphorylation is the final stage of aerobic cellular respiration that produces maximum ATPs.
