Answer: Option B the ability to write.

Acquired traits are the ones which an organism acquires due to the environmental and social influence throughout their lifetime.

These traits are neither inherited from the parents nor transferred to the progenies.

Some of the common examples of acquired traits in humans are knowledge, writing skills, the ability to sing or dance and so on.

Question

son4ous [18]

Answer:

Suppose you have a parent plant with purple flowers and a parent plant with white flowers. Because the b allele is recessive, you know that the white-flowered parent must have the genotype bb. The purple-flowered parent, on the other hand, could have either the BB or the Bb genotype. The Punnett square in Figure below shows this cross.

In gel electrophoresis, how are the dna samples added to the wells?.

jenyasd209 [6]

DNA samples are added into wells with the help of electric current.

<h3>How dna samples added to the wells?</h3>

DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

So we can conclude that DNA samples are added into wells with the help of electric current.

How can you distinguish a clastic rock from that of a bioclastic rock

IRISSAK [1]

Bioclastic rocks are actually sub-parts of clastic rocks, not a completely different thing altogether.

Clastic rocks are made up of loosened bits of pre-existing rocks. These rocks are formed from weathering, breaking those larger rocks down into little particles (for example, a grain of sand) due to external weather factors such as wind or rain. Some examples of these rocks would be sandstone, conglomerate, and silistone. They are classified by the size and shape of the fragments they are made up of.

Bioclastic rocks are also made up of loosened bits, however, they are not made of rock. They are made of fossils and biogenic (made by living organisms) particles (for example, pieces of shells and coral). These rocks are formed from small parts of pre-existing organisms compacting together to form a rock. Examples of this type of rock would be coquina and limestone, or more specifically, bioclastic limestone. Bioclastic rocks have a very crystalline texture and it is highly likely that you will see a shell in this rock type.
