Give an example of spinal reflex and explain how the nervous system functions in this reflex action

1 answer:

3 0

The patellar reflex is the most common example or a spinal reflex. When the knee is tapped, the nerve that will receives this stimulus sends an impulse to the spinal cord and relay it to the motor nerve. This sources the quadriceps muscle at the front of the thigh to contract and twitch up the leg. This reflex contains simply two nerves and one synapse. The leg will start to twitch up on the other hand the brain is just suitable aware of the tap and comprehends the situation. Subsequently the tap, the leg is routinely lengthy once and comes to rest. The nonappearance of this reflex is problematical and recognized as westphals sign this reflex might be lessened or absent in lower motor neuron lesions and during sleep.

Which of the following statements about DNA isolation from E. coli is not correct?

Ulleksa [173]

Answer:

The correct answer is c. detergent is used to break apart plant cells to extract DNA.

Explanation:

Here we are talking about DNA isolation in E.coli and detergent is used to break apart the bacterial cell membrane by destabilizing the cell membrane. Detergent disintegrates the proteins present in the cell membrane which causes the rupture of membrane releasing the cell extract outside the cell.

Detergent is not able to break plant cell because it is made up of cellulose and require blending or mashing. Detergent can only be used to disintegrate the cell membrane because only cell membranes contain lipids and proteins.

Hence, the correct answer is c. detergent is used to break apart plant cells to extract DNA.

2. A theory is an explanation that has

kotegsom [21]

Answer:

A theory is a reasonable explanation of the phenomena observed in nature, with much evidence to support it (option C).

Explanation:

A theory gathers a set of hypotheses that can be demonstrated and constituted on a scientific basis, until they are questioned by other evidence.

To construct a theory, the processes of observation, deduction and investigation must be thorough, but leave open the possibility of being discussed and refuted in the absence of definitive arguments.

A theory becomes law when it has been proven beyond a doubt.

Part b - comparing eukaryotic and prokaryotic cells two fundamental types of cells are known to exist in nature: prokaryotic cel

Alexeev081 [22]

<h3>Answer;</h3>

Prokaryotic only: nucleoid
Eukaryotic only: nucleolus, lysosome, mitochondria
Both: plasma membrane, ribosomes, flagelia

<h3>Explanation;</h3>

Prokaryotic cells are those cells that lack nucleus and other membrane bound organelles, unlike eukaryotic cells which contain a membrane bound nucleus and membrane bound organelles such as mitochondria, and lysosomes.
Prokaryotic cells lack the nucleus and nucleolus, but instead contain a nucleoid which contains the genetic materials of the cell.
Eukaryotic cells on the other hand contain a well defined nucleus, that contains nucleolus and highly complex genetic material.
Despite the differences, they both share a number of organelles and characteristics such as plasma membrane, which regulates the movement of substances in and out of the cells, ribosomes, sites for protein synthesis, and also flagella, for locomotion.
