Answer:
C. Jenny counts the eggs laid by each chicken for a month.
Explanation:
The answer C represents data being collected because it involves numerical data instead of thoughts.
Answer:
the cell wall surrounds the plasma membrane of the cells and provides strength and protection against mechanical and osmotic stress.
"glazed"
Glazing is the process of covering a ceramic piece with glass allowing it to hold liquid (and food) without leaking. when left a small part of the ceramic not glazed allows the pottery piece to be fired in a kiln without exploding.
The question is incomplete as it does not have the options which are:
The empty vector would migrate the same distance as the cloned vector.
It is impossible to know without knowing the identity of the gene of interest.
The empty vector would migrate farther down than the cloned vector.
The cloned vector would migrate farther down than the cloned vector.
Answer:
The empty vector would migrate farther down than the cloned vector.
Explanation:
In recombinant technology, an empty vector is considered a vector which is present without the gene of interest and thus is of small size and the cloned vector is the vector which has a gene of interest along with the usual sequence.
The cloned vector is larger compared to the empty vector as the cloned vector has a gene of interest whereas the empty vector does not have.
In-gel electrophoresis technique, the DNA samples are run and the size of the fragment is known according to the ladder sequence which is used as a reference and have the band size in increasing order from lower side to upper side.
When the vectors sun on the gel, the small size gene will move faster and to the farthest distance compared to the larger DNA that is empty vector will cover the maximum distance while the cloned vector will cover the less distance.
Thus, the selected option is correct.
Answer:
receptores de los nervios motores
Explanation:
Un calambre es un tipo de espasmo que afecta a los músculos del cuerpo y que puede llegar a producir dolor. En general, los calambres están asociados con el tensamiento o el uso desmedido de un músculo. Los calambres se producen como consecuencia de la excitabilidad anormal de los nervios motores que inervan los husos musculares y de la inhibición del órgano tendinoso de Golgi. Cuando un músculo está fatigado, la actividad del órgano tendinoso de Golgi que está conectado a las fibras musculares disminuye. En condiciones normales, el órgano tendinoso de Golgi inhibe la contracción en respuesta a la tensión muscular, pero en un calambre se produce una disminución en su actividad y un aumento en la excitación de los husos musculares, lo cual puede desencadenar en un calambre.
