Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, one similar substance that, if missing, many cycles (particularly the two cycles/processes provided in the question) will not exist/proceed is the sun/sunlight.
In the water cycle for instance, if there is no sun/sunlight, there will be no heat to allow for evaporation of water from the water-body (ocean, sea, stream or lake) hence there will be no cloud of water droplets in the atmosphere. The implication of this is that, the first process of the water cycle will not proceed, hence the cycle will not exist.
During photosynthesis, carbondioxide reacts with water in the presence of sun/sunlight to produce glucose and oxygen. The absence of sun in this reaction will not lead to the production of glucose which is the useful product of photosynthesis for plant.
From the explanation above, it can be deduced that <u>the absence of the sun/sunlight will prevent the two cycles from existing</u>.
Answer:
Oxidized
Explanation:
Compounds that lose or donate electrons are also called electron donors. They act as reducing agents in chemical reactions where they reduce the oxidation states of compounds they react with and they become oxidized themselves.
For example; in the reaction between Hydrogen gas and oxygen to form water
2H+ + O2- _____> H20
Two hydrogen atoms donate their electrons to an oxygen atom, reducing the oxidation state of oxygen to 2- and oxidized itself to +1
Answer: They all eat new twigs, grasses, and leaves
Answer:
They became closer to each other.
Explanation:
When skeletal muscles contracts the Z lines that are at the end of every sarcomere became closer to each other due to the fact that the I bands that are attached to the Z lines and contains the myosin filaments move closer to each other interacting with the actin filaments and shorten the the H zone that is in the middle of the sarcomere. In other words, It all becomes compact during a contraction.
The answer is D. Cattle have microbes in their stomach that produce methane during digestion
