Answer:
The correct sequence is 3,1,4,2 and 5.
Explanation:
In the reflex arc, a signal is generated by the sensory cells and is conducted with the help of interneurons and returns back using motor neurons to bring out the reflex. The nerve pathway taken by a reflex action is known as a reflex arc. In the process, a receptor situated in the skin determines a stimulus. After that the sensory neuron transmits electrical impulses towards a relay neuron, and this relay neuron associates sensory neurons to the motor neurons. The motor neurons further transmits electrical impulses to an effector. The effector eventually generates a response.
Answer: 20 fragments
Explanation:
This particular restriction enzyme has a 4 bp (base pair) recognition sequence therefore it will cleave once every 4ⁿ bases where n indicates the number pf bases in the recognition sequence.
- The recognition sequence is 4 bp therefore this restriction enzyme cleaves once every 4⁴ = 256 bases. This is the length of the restriction fragment.
- Calculate the number of fragments by dividing the total number of bases ( where you assume equal frequency of bases ie. A+T = C+G) by the length of the restriction base.
- therefore 5000bp/256bp = <u>19,53</u> now this number ca n be rounded up to 20.
- The expected number of fragments on the electrophoresis gel will be 20 fragments.
The cardiac notch is the concave area in the left lung that leaves a space for the heart to accomodate. The corrcet answer is <u>cardiac notch</u>.
<h3>
What is the cardiac notch?</h3>
The left lung has superior and inferior lobules, one oblique fissure, it is adjacent to the heart, the aortic arch, the thoracic aorta, and the esophagus. It also has a cardiac notch.
The cardiac notch is a concave lung area where the heart accommodates. Its main function is to leave a space for the heart to lay. It is placed in the anteroinferior border of the superior lobule of the lung.
Since the cardiac notch is the area where the heart is placed, it only appears in the left lung.
The correct answer is cardiac notch. The medial surface of the left lung has a cavity that accommodates the contents of the mediastinum. It is called the _<u> cardiac notch</u>_.
