Answer:
A) repressors
Explanation:
A transcription factor is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to specific DNA sequence. The function of TFs is to regulate-turn on and off genes-In order to make sure that they are expressed in the right cell, at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth and cell death throughout life.
Bottleneck is an example of a genetic drift that happens when the size of a population is severely reduced.
Answer: Beaks---->Evolution, Natural Selction, Genetic Drift, Behavioral Isolation, n Non-random mating...
Explanation:
Darwin observed many discoveries like the Galapagos tortoises, iguanas, penguins, crabs, etc...But one of the most important ones that definitely helped to see the evolution and the process of natural selection is the Galapagos finches they changed a lot mainly because of environmental changes. The Galapagos Islands are special to evolutionary history firstly because there are a lot of different sizes and colors in birds but the main focus was that after Earth was a Pangea, all land united, genetic drift occurred in the Galapagos island meaning that a small population was 'trapped' inside with no way of getting new traits though that's not exactly right because we not only change genetically but also by environmental changes and humans change it too of course(like hunting). Another important discovery that was found there wasn't only hints of evolution and natural selection but also behavioral changes especially in mating, some birds sing or dance it really depends but if some animals don't mate then new species are formed that's one of the reasons why it created a lot of diversity; Another reason to the topic of reproduction is non-random mating, some organisms are looking for some specific location or phenotypes in their mates if they don't find it they look for them in their own species which can cause the extinction of that species or spread it.
The Red sea is an example of a landform created by a divergent plate. Thus, the correct option is C.
<h3>What are Divergent plates?</h3>
Divergent plates may be defined as a location where two tectonic plates are locomoting away from each other, vacating a void between them that can be sufficed with magma.
Divergent plate movements are mainly responsible for separating the bodies of African and Arabian water from one another.
Therefore, it is well described above.
