If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: _________
Dependent: __________
Other variable(s): ________
Answer:
If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: temperature.
Dependent: leaf color.
Other variable(s): According to the information, there are no other variables.
Explanation:
When formulating a hypothesis, it is inevitable that the presence of variables on which the hypothesis is formed is established. The hypothesis raised is the effect of temperature on the color change of the leaf of a plant.
The independent variable, used in research work, is an element that does not depend on other variables but can influence the behavior of the dependent variable. In this case, the independent variable is the temperature. In addition, the independent variable can be managed to observe its effect on other variables.
An dependent variable is a characteristic that is influenced or modified by the presence of other variables, such as the independent variable of a study. In this case is the color of the leaf of a plant.

An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory.
Part 1: What is happening at location G?
Part 2: Which type of energy transformation is taking place at this location?
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer.
Answer:
This is too difficult to read and understand... if you had a diagram I could be able to help more, but I can't figure out exactly what your asking... all I know is part A is CO2 being released into the atmosphere...
Hope you have a great day and if you have a diagram let me know.. I'd love to help :D
Answer:
Part I
At location G, the process of combustion is taking place where hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide and water as the products.
CxHy = CO₂ + H₂O
Part II
At point G there is no transformation of energy since during the process of combustion energy will still be stored in form of chemical energy in the bonds of carbon Iv oxide and the water produced during the reaction.
Part III
The process shows recycling of carbon in the carbon cycle. This is because carbon from living organisms is cycled to non living organisms. When plants and animals die and are buried deep in the ground, they are then slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds. Then the fossils are used in the industries and undergoes combustion releasing carbon iv oxide which is then released to the atmosphere and used by the plants and animals. The process starts once again.

Describe mechanism of blood circulation.
Answer:
Look down!! ;)
Explanation:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

Anaerobes carry on whereas aerobes carry on cellular respiration
Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic Respiration
Occurs in the presence of free oxygen.Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. Respiration occurs in the mitochondria.Takes place in two steps or stages: Krebs cycle and electron transporter chain. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.Anaerobic Respiration
Occurs in the absence of free oxygenSeries of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation. Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.Explain how a mutation has caused the Lactase Persistence gene in some people and not in others.
Answer:
It is a case of human niche construction
Explanation:
Lactase is an enzyme of mammals which is required to digest lactose. In humans (like in other mammals), lactase activity decreases during mid-childhood; although there are individuals which are still capable of producing this enzyme even during adult life, a trait known as 'lactase persistence'. Different mutations in the coding region of the lactase gene have been associated with lactase persistence in European, African and Asian populations. On the other hand, the niche construction theory states that the organisms, through their activities and choices, actively modify their own local environment by introducing novel selection pressures. Some examples of niche construction include, among others, alternation of nutrient cycling by plants or lactase persistence in humans. Lactase persistence can be defined as a case of niche construction because this trait was not only genetically inherited but also culturally transmitted through local environments shaped by ancestral populations, i.e., generated by niche construction or ecological inheritance.

Why is it important we reduce the amount of greenhouse gases we
put into the atmosphere?
Answer:
Mhm
Explanation:
Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. ... Putting so much new CO2 into the air has made Earth warmer.
Answer:
If we don't reduce the emissions of greenhouse gasses, we will end up have climate change. As the world heats up, the water levels rise, the polar ice caps melt and costal cities will end up under water at somepoint. Also animals that can't handle the temp changes can die.

higher rate of photosynthesis when light intensity is below 200 umol photons/mº/s?
When light intensity is above 400 umol photons/mº/s?
Answer:
Below 200 umol photons/mº/s, shade plant grow best.
Above 400 umol photons/mº/s, sun plant grow best.
Explanation:
A shade plant has a higher rate of photosynthesis when light intensity is present below 200 umol photons/mº/s because shade plants needs low light intensity for higher photosynthesis while on the other hand, a sun plant has a higher rate of photosynthesis when light intensity is above 400 umol photons/mº/s because it requires high intensity of light for photosynthesis if other factors are also present in large amount such as water and nutrients in the soil.

A _______________ from the sun hits chlorophyll and excites an electron, known as __________________________________.
Answer:
Photon, light dependent reaction of photosynthesis
Explanation:
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.
There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.
In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.
Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".
