Answer:
Una variable de control (o constante científica) en la experimentación científica es un elemento experimental que es constante y sin cambios durante el curso de la investigación. ... Las variables de control en sí mismas no son de interés primario para el experimentador.

Answer:
They act to regulate the expression of specific genes (androgen-responsive)
Explanation:
Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".
Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.
This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.
This process helps to direct the development of male sexual characteristics.
<h3><u>
Answer;</u></h3>
C. Different species can share the same common name.
<h3><u>Explanation;</u></h3>
- <em><u>Different organisms can share the same common name</u></em>, and thus the reason why scientists avoid using common naming while naming organisms.
- Additionally, s<em><u>cientists avoid using common names because they are not specific to a specific species.</u></em> For instance, Robin is a common word that may be used to describe the many species of robin that are found in different regions of the earth, for example, Robin in England which has yellow breast, and robin in United states and have red breasts.
- Therefore, <em><u>for the purpose of avoiding ambiguity and confusion in naming organisms scientists use scientific names while identifying various species.</u></em>
The correct answer is neutrons, they do not carry an electronic charge.
Hope this helps.
