Answer: a. Photo-periodism
Explanation:
The relative length of the day is considered as a major factor in the development of plants, particularly in sexual reproduction. The plants were grouped considering that the flowering and fruiting occurs only when the length of the day is within certain limits so that these phases are achieved only in certain times of the year. Therefore, some species respond to long days, while others respond to short days, and still, others are capable of responding to all day lengths. The name and meaning of each group became as follows:
Short Day Plants: They are the species that bloom in smaller photoperiods than a critical maximum.
Long day plants. These are the species that bloom in larger photoperiods than a critical minimum.
Neutral day plants: They are those that bloom in a wide range of the photoperiod.
i don’t get this lol but ok
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.
Answer: mitotic phase
Explanation:
The cell cycle has two phases the Interphase and mitosis. Interphase is the growth phase where the cell prepares itself for the cell division. It is divided into three phase G1 phase( Cell growth),S phase ( DNA synthesis) and G2 phase(cell growth).
Mitotic phase has a multiple steps this is where the duplicated chromosomes are aligned or arranged, separated, and move into two new, identical daughter cells(cytokinesis)
The first step in the mitotic phase is called karyokinesis or nuclear division where the chromosomes are separated and move in opposite direction and the second portion of the mitotic phase, called cytokinesis which is the physical separation of the chromatids into the two daughter cells.
