Answer:

BTB respond to the presence of carbondioxide by changing color.

Explanation:

Bromthymol blue is a chemical indicator dye that changes it color to yellow in the presence of an acid. It respond in the presence of carbondioxide and form carbonic acid, therefore lowering the pH. It becomes blue if the pH is greater than 7.6, it is green if the pH is between 6-7.6 and yellow if the pH is less than 6.

If an object turns but maintains the same speed,has its acceleration changed?explain
Andreas93 [3]
Acceleration is defined as the rate of change of velocity
Since velocity is a vector, it has both speed and direction.
So, if the object is travelling in a straight line at a constant speed, then it will not be accelerating. Both Magnitude and direction are constant.
However, if the object is travelling in a circle at a constant speed, then it'll be accelerating. An Object going in a circle is constantly changing it's direction, which means velocity is changing, so there is an acceleration caused by a net force.
Hope this Helps :)

Prader-Willi syndrome is a genetic disorder involving a partial deletion of chromosome 15q on the paternal chromosome. When both
Kay [80]

Answer:

genomic imprinting

Explanation:

Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.

Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.

Blo 182 in assignments the artificial selection of which organisms was useful for darwin to come up the term natural selection?
miss Akunina [59]

When Darwin returned to England aboard the HMS Beagle after his voyage to the Galapagos Islands, he used artificial selection to help gather data to justify his theory of evolution. After studying the finches on the islands, Darwin moved to raising birds, notably pigeons, back home to test his theories.

<h3>What, according to Darwin, is artificial selection?</h3>

Artificial selection is the discovery of desirable qualities in plants and animals by humans, as well as the procedures taken to improve and maintain such traits in future generations.

They may adjust an organism's properties by choosing which creatures were permitted to reproduce. . Darwin referred to this form of alteration in organisms as artificial selection.
