4.identifying and controlling variables
The most important part of an experiment would be; identifying and controlling variables.
In order to set up an experiment, you need to test the specimen(s) with and without a curtain variable. That is what makes an experiment a test.
Answer:
identify and controlling variables
Explanation:
lack of awareness of control variables can lead to faulty result or what are called "confounding variables" additionally, noting control variables makes it easier to reproduce and experiment and establish the relationship between the independent and the dependent variable
The answer is- EXCEPT: Type O
Answer:
Explanation: The difference is that El Nino warms and La Nina cools.
Answer:
Blood type A (genotype AO) or blood type O (genotype OO).
Explanation:
Okay, so if one of the parent's has blood type B (genotype BB) and the child has blood type O, it means that the B allele is not present in the child's genotype. Which would mean that the other parent would likely have either Blood Type A or Blood type O.
b. a-hemoglobin is present only in cells where B-hemoglobin is absent
c. a-hemoglobin mRNA is more stable than B-hemoglobin mRNA
d. Tubulin inhibits translation of hemoglobin mRNA
Answer:
Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.
Answer:
parasympathetic nervous system
Explanation:
The parasympathetic nervous system is the one that controls involuntary functions and acts. The nerves that integrate it are born in the brain, forming part of the oculomotor, facial, glossopharyngeal and vagus cranial nerves. In the spinal cord it is found at the level of the sacral roots of S2 to S4. It is responsible for the production and restoration of body energy.
The neurotransmitter of this system in pre and postganglionic neurons is acetylcholine (endogenous neurotransmitter). The nerve centers that give rise to the parasympathetic preganglionic fibers are located both in the brain and in the sacral plexus in the spinal cord. These nerve fibers branch through the territory of some cranial nerves such as the facial nerve or vagus nerve or the pelvic nerves in the sacral plexus.
The main function of the parasympathetic nervous system is to cause or maintain a state of rest or relaxation after an effort or to perform important functions such as digestion or sexual intercourse. It acts on the stress level of the organism reducing it. Performs oppositely complementary functions with respect to the sympathetic nervous system.
