Bacteria found in the roots of legumes(beans) do nitrogen fixation.
The correct answer is all of these.
Matter and energy on Earth are never destroyed or created out of nothing, but just transferred or converted to another form.
The inorganic matter is transferred to the living things from the physical environment by many biological processes like photosynthesis ( CO2), nitrogen fixation, absorption of the minerals by plant roots and many more.
Matter can then be transferred between different organisms through the food chain.
Eventually, the matter will return to the physical environment when organisms decompose and the cycle will start again.
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.
<h3>What is the smallest contractile unit within skeletal muscle?</h3>
A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.
In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.
