Answer:
Activated
Explanation:
In the presence of lactose, and in the absence of glucose, lactose will bind to a protein called a "repressor," deactivating it. Through this, RNA polymerase has a free way to synthesize the mRNA that will give enzymes for lactose degradation.
<u>Answer</u>:
It is important for the chromosomes to condense during mitosis to facilitate chromosome movement.
<u>Explanation</u>:
The chemical called colchicine is found to be used during the process of mitosis, so as to freeze the cells, which can stop or prevent the movement of the chromosomes. This process is also essential for the faithful genome replication or transmission to those daughter cells. During the interphase cell division occurs but during the prophase the cell condensation is found to be happening. Before the process of the mitosis chromosomes are allowed to move and during this entangled and breaking were also noticed.
Answer:
The correct answer is a. anaerobic metabolism.
Explanation:
Anaerobic metabolism refers to a high intensity of exercise in which the absence of oxygen limits performance due to the accumulation of metabolites and the corresponding metabolic and physiological dysregulation.Predominantly anaerobic exercises are characterized by: high intensity and short duration, energy is obtained from immediate sources such as muscle ATP, phosphocreatine (PC) and glucose and does not need oxygen for this. For very explosive or high intensity movements it is necessary to obtain a powerful and fast energy, this is obtained by anaerobic systems. The anaerobic metabolism is able to respond immediately to the energy demands of physical exercise and can provide energy for very high intensity exercises (strength and / or power). But this system has a limited capacity, it is short-lived, so if the exercise continues, either you have to stop due to fatigue or reduce its intensity (the power developed) to a level where energy can be obtained through the aerobic metabolism.
A disaccharide is formed by two monosaccharides through a condensation reaction. The Hydrogen of one of monosaccharide pairs with the hydroxide (OH) of another monosaccharide. Whe this happens H2O is formed The water molecule is then removed leaving the functional groups of the two monosaccharides able to bond with each other.
The given question is incomplete. The complete question is
What is not a risk of being underweight?
Answer:
Higher risk of developing heart disease
.
Explanation:
The individual can be characterized as healthy person, over weight and under weight. The under weight person has low weight as mentioned in the criteria of the body mass index.
The overweight person feels low and has less energy to do any work. They may also suffer from the anemia condition, and have low nutrition in their body. They cannot develop the risk of the heart disease because heart disease is more common in over weight people.
Thus, the correct answer is option (e).
