In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.

24. Name two types of pathways that help a body maintain homeostasis, and an example of each.
gavmur [86]

Answer:

See the answer below

Explanation:

Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways

  • <em>Negative feedbacks</em>
  • <em>Positive feedbacks</em>

Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat

Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.

Which of the following is an example of gene flow?
kykrilka [37]
<span>When the genes propagate from one area to another. 
The founder effect happens when genetic diversity declines due to an external larger group of organism invades a set of current living population. An example of this process is when the British colonies invaded the Mesoamerican continent where native americans lived and were outrun by the British colones, especially since many wars were made and ethnic cleansing. </span>
