How respiratory system works at the organ level? PLEASE HELP ME!!!!!!

The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe. The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air.

Amylase becomes denatured at a temperature of 80°C. During an experiment to study the effect of varying temperature on enzyme activity, amylase's reactivity with starch was measured at body temperature (37°C), and then again at an increased temperature of 42°C. How would this increase in temperature affect the experiment? A) The reaction will stop. B) The enzyme would become inactive. C) The rate of reaction will increase. D) The rate of reaction will decrease.

C, When you want to dissolve salt or sugar into water, it dissolves easier and faster in hot water than cold water. he increase in temperature affects the experiment in such a way that amylase does not efficiently break down starch than it was in normal body temperature (37°C). This is because the structure of amylase will change, thus it cannot interact well with starch than its original structure at  37°C.

QUESTION POSTED AT 16/02/2020 - 07:06 PM

I need help with five multiple choice marine science questions. 1)When severe weather damages the plant life in an ecosystem, what effects might this have on other organisms in the same ecosystem? a)- Other organisms could starve or have to leave the area if they depend on the plants as food. b) -Other organisms could change their behavior to take the place of the plants in the ecosystem. c )-Other organisms would not be affected. d )-Other organisms could replace the plant energy with radiant energy from the sun. 2)As the climate changes, the average ocean temperature is rising. Using this information, predict what will most likely happen to El Niño events in the future. a)-El Niño events will intensify because they rely on warmer water sinking to the seafloor. b)-El Niño events will intensify because they will build on the already warm waters at the equator. c)-Some El Niño events will be stronger, but most will be weaker because the ocean currents are unpredictable. d)-El Niño events will become more similar to La Niña events and establish a new weather pattern. 3)Which of the following examples is the most likely way severe weather can negatively affect the biodiversity of a marine ecosystem? a)-A severe thunderstorm brings rain and wind to an intertidal zone. b)-A storm surge from a hurricane floods a coastal area. c)-A tornado causes a waterspout. d)-A blizzard adds snow and ice to an arctic glacier. 4)El Niño events are characterized by warmer than normal ocean temperatures near the equator in the Pacific Ocean. Which weather events are most likely to occur as a result? a)- Increased rainfall across the eastern Pacific Ocean b)-Decreased flooding across the eastern Pacific Ocean c)-Drought along the South American Pacific coastline d)-Colder winter along the South American Pacific coastline 5)According to the Severe Weather Activity worksheet, El Niño events most likely occurred during which of the following years? a)-2006 and 2015 b)-1997, 2006, and 2015 c)-1997 and 2015 d)-1997 and 2006

1. The answer is A. The eradication of plants in an ecosystem would devastate the food web in the habitat. This is because plants are primary producers and significant as conduits of energy into a food web. Plants convert radiant energy from the sun to biomass through photosynthesis. This energy then transferred up the food chain through various form of interaction such as predation.

2. The answer is B. Global warming causes water at the equator to be even warmer above normal temperatures. This fans the upwelling of cold water from below the ocean floor and causes an even greater disparity of temperatures across the Pacific ocean. This subsequently fans the trade winds hence warming the air even more and causing severe storms.

3. The answer is B. The flooding of the coastal area due to hurricanes destroys the biodiversity of the ecosystem by physically destroying the habitat and by drowning organisms such as affecting a whole species population. This upsets the balance of the ecosystem and makes it prone to even further deterioration.

4. The answer is A. When the surface ocean waters at the Pacific ocean warm at the equator, there is an upwelling of cooler ocean waters from the bottom of the ocean., The warm currents along with trade move towards the east and met the South American coastline where they bring in heavy rainfall. Conversely, the northwestern region of the Pacific experiences drought.

5. The answer is C. Elnino and La Nina occurs at a frequency of approximately two(2) to seven (7) years. The phenomenon usually lasts nine (9) to twelve (12) months. El Ninos are more frequent than La Ninas. Their peak effect is usually felt around December and January. The strongest El Nino was the one that occurred in 1997.

You visit a farm and notice that white chickens lay white eggs and colored chickens lay brown eggs, so you decide that only white chickens lay white eggs. What type of reasoning is this? a) inductive b) deductive

Answer

Inductive

Explanation

Its a logical process in which a number of premises  all believed true or sometimes found  true most of the time and combined to come up with specific conclusions. Its mostly used in applications that do involve  behavior, forecasting and makes broader generalization that is considered probable. For example a speculation that all crows are black and each time a new crow is observed  and found out that its black the assumption is increasingly confirmed. On the other hand if the crow is found not to be black then the assumption's found to be false..

The alpine tundra are spread all over the world. They are located on high altitudes and have mountains. the soil is well drained, but the higher altitudes does not support tree growth.

The arctic tundra are present near the north pole, the atmosphere there is very cold. The conditions are almost desert like, but have some dwarf tress along with shrubs and lichens.
