With reference to the induced fit model, describe how the tertiary structure of a named enzyme facilitates its function as a biological catalyst
The induced-fit model includes the change in the conformational site of the substrate and enzyme. It is done till the enzyme completely binds the substrate. This will then activates the enzyme to perform its work.
What is induced fit theory?Induced fit theory or model suggest that the activation site of enzymes and the binding site of substrates undergo some conformational changes to fit into each other.
This binding results in activation of the enzyme and as the enzyme has a three-dimensional tertiary structure, this would help it to get fitted into the substrate.
Thus, with reference to the induced fit model tertiary structure of enzyme facilitates its function as a biological catalyst.

Suggest a means by which you could separate mrna from the other types of rna in a eukaryotic cell
A method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.
What do you mean by mRNA?mRNA may be defined as a molecule in cells that holds codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm.
The mRNA can be easily isolated from other types of RNA by the most reliable and convincing method of oligo (dT) chromatography which is the magnetic separation method that bounds oligo (dT) molecules on the surface of paramagnetic beads.
Therefore, a method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

Which environmental factor can lead to a decreases in the genetic variation of the population of tuna
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.

imagine that you are kneading dough for homemade pizza. Describe how the different areas of your body communicate through the nervous system.
Answer: you are using a few
Explanation:Your brain tells you hades to knead the dough and tells you how to move your arms hands
The nervous system is the control and the coordination center that passes the signals in the body. The motor and sensory actions work in accordance with the muscular system.
What is the nervous system?
The nervous system is the commanding center that controls the body's movement in response to action and stimuli. The body receives an action in the form of kneading in case of making pizza.
The somatic nervous system sends the sensory impulses to the brain and the spinal cord of the body to react to the kneading action. The impulses are received by the brain and the motor nerves send the reaction back to the muscles.
Therefore, the sensory and the motor nerves communicate in the nervous system.

Five cellular targets of antibiotics were exploited withinside the improvement of antimicrobial drugs: cell wall synthesis, protein , ribonucleic acid , (DNA) , and middleman metabolism.
How do antibiotics acts as resitance?The principal mechanisms of resistance are: proscribing uptake of a drug, amendment of a drug target, inactivation of a drug, and lively efflux of a drug. These mechanisms can be local to the microorganisms, or received from different microorganisms.
In principal, there are 3 principal antibiotic objectives in bacteria: The cell wall or membranes that surrounds the bacterial mobileular. The machineries that make the nucleic acids DNA and RNA. The equipment that produce proteins (the ribosome and related proteins).

Which system does the endocrine system interact with to regulate water
levels in the body?
O A. Respiratory system
O B. Excretory system
O C. Reproductive system
O D. Digestive system
Answer:
B. Excretory system
Explanation:
Because the excretory system is made to remove urine which consists of waste materials such as excess salts and water. The kidneys are present in it as well. If there is too much water in the body the excretory system will produce urine with higher water concentration so whiteish urine will be produced and if there is a low amount of water in the body the excretory system will produce urine with lower water concentration so yelloish or greenish urine will be produced
