"Conjugation" is the one process among the following choices given in the question when <span>two protists exchange genetic material. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has come to your great help.</span>
Desired function of a garden is a planned space, usually outdoors, set aside for the display of an area.
The subsystems in a garden are plants, soil, water.
( I’m not entirely sure if I’m correct because I don’t really know what subsystem means but this is the best I got.)
Answer:
a) The annealing temperature may be defined as the temperature required to join or anneal the DNA strands. If the annealing temperature will be too high the primers may denature in the PCR reaction and no amplification of DNA will occur.
b) The annealing temperature is too low, the primers are unable to bind with the DNA and no reaction of PCR will occur. Too low annealing temperature will not favor the primers to bind and amplify the DNA.
Answer:
An immunized person can show false positive results during the test.
Explanation:
BCG (bacille Calmette-Guerin) is the vaccine which is given for tuberculosis. This vaccine is used in many countries in which the chances of spreading Tb is high in children which causes meningitis and miliary disease in children.
In United States, BCG is not recommended because the risk here is very low and the vaccinated person can show false-positive results for the disease which will result in hindering the work of epidemiologists who are tracking how and from where disease spread.
Answer:
1. Acetylcholine is released from neuron . 2.Acetylcholine binds receptor 3. Calcium ions released by sarcoplasmic reticulum. 4. Sarcolemma action potential is propagated. 5. Sodium enters the muscle cell.
Explanation:
A neural signal is the electrical trigger for calcium release from the sarcoplasmic reticulum into the sarcoplasm. Each skeletal muscle fiber is controlled by a motor neuron, which conducts signals from the brain or spinal cord to the muscle. Electrical signals called action potentials travel along the neuron’s axon, which branches through the muscle, connecting to individual muscle fibers at a neuromuscular junction. The area of the sarcolemma on the muscle fiber that interacts with the neuron is called the motor-end plate. The end of the neuron’s axon is called the synaptic terminal; it does not actually contact the motor-end plate. A small space called the synaptic cleft separates the synaptic terminal from the motor-end plate.
Because neuron axons do not directly contact the motor-end plate, communication occurs between nerves and muscles through neurotransmitters. Neuron action potentials cause the release of neurotransmitters from the synaptic terminal into the synaptic cleft, where they can then diffuse across the synaptic cleft and bind to a receptor molecule on the motor end plate. The motor end plate possesses junctional folds: folds in the sarcolemma that create a large surface area for the neurotransmitter to bind to receptors. The receptors are sodium channels that open to allow the passage of Na+ into the cell when they receive neurotransmitter signal.
