I’m pretty sure the answer is A because carbon dioxide causes a solution to turn yellow and a solution that indicates no carbon dioxide would be blue instead of green.
Answer: Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein. ... And when the amino acids of a protein stay the same, researchers believed, so do its structure and function.
Answer: The most accepted guess is: By bamboo rafts.
Explanation:
There are two hypotheses.
The first is that they arrived on Flores as Homo erectus and then evolved to Homo floresiensis. The second is that they were already Homo floresiensis when they arrived. This second one is the more accepted hypothesis because it would take organization and language to accomplish this technological water transportation feat. Homo erectus is not known to have developed speech.
Now at the time this transport was estimated to have happened, 100000 years ago, the islands of Komodo and Flores were joined and visible from the mainland. Together they constituted a 19km wide straight visible that could be easily seen from the mainland. The Homo floresiensis tribes built bamboo rafts, or possibly some other floating apparatus made if wood, and sailed there. The islands then progressively drifted apart, isolating them.
PS: It is important to note that some things may have drove them there such as famine, violence, etc.
It is true. In drosophila, distinct sets of maternal impact gene products must accumulate in the proper region of the embryo to ensure proper anteroposterior and dorsoventral development.
<h3>What makes Drosophila unique?</h3>
The use of Drosophila over vertebrate models has many technological advantages;
- they are simple and affordable to culture in lab settings,
- have a significantly shorter life cycle,
- produce huge numbers of externally deposited embryos
- may be genetically manipulated in a variety of ways.
<h3>Why is Drosophila referred to be the genetic Cinderella?</h3>
- Drosophila, which means "dew loving," is derived from the Greek word drósos.
- Fruit flies, or Drosophila melanogaster, are referred to as the genetic Cinderella.
- This term was given to them because of their 12-day lifetime, ease of culture, and ability to produce numerous offspring from a single reproduction.
