I believe it would be (B) but i’m sorry if i am wrong.
This is an example of Precursor gene regulation (protein translation) type of eukaryotic gene regulation.
<u>Explanation:</u>
The source which breakdown proteins into smaller amino acid is pepsin and generated as top cells within stomach lining or membrane, responsible for pepsinogen emission inside stomach. It is represented as zymogen having an extra 44 amino acids linkage as its primary structure. Hydrochloric acid (HCl) releases this zymogen which is emitted from the parietal cells in the stomach lining.
Once food is consumed, the hormone gastrine and the vagus nerve cause the secretion of both pepsinogen and HCl from the stomach lining. Hydrochloric acid induces an acidic environment that allows pepsinogen to unfold in an autocatalytic manner and thus generates pepsin the active form.
Answer:
One.
Explanation:
The attached figure shows the diagram of the given question.
We need to find how many angles are alternate exterior angles with angle 5?
Exterior angle = Angle that is made outside of the shape
Alternate angle = an angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
Answer:
esta es una expresión de admiración ante la belleza de los mecanismos evolutivos
Explanation:
El concepto de evolución como mecanismos naturales que está actualmente en boga fue originalmente planteado por Charles Darwin en su celebre publicación "El origen de las especies" (1859). La teoría de la evolución de Darwin está basada en la idea que las especies cambian constantemente con el tiempo a través del proceso de selección natural. Este mecanismo es responsable de la inmensa biodiversidad biológica observada en la naturaleza, la cual incluye la evolución de las especies, poblaciones y organismos individuales. Desde una perspectiva biológica, es imposible no quedar fascinado ante la naturaleza y contemplación de los procesos evolutivos.
