Explain the process of evolution through isolation that results in speciation.

Answer:

Evolution is a natural phenomenon by which inheritable characteristics of a species change over generations.  

It mainly relies on processes such as natural selection, genetic drift, migration, and mutation.

Heredity, genetic variation, and differential reproduction result in evolution with the help of natural selection.

Isolation (geographical or reproductive) prevent the flow of genetic material between the populations. With time, the populations evolved in different species as a result of adaptation towards different habitat or niche (natural selection).

For example, in Galapagos islands finches were isolated through different islands. The flow of genetic material was restricted. In addition, natural selection helped different populations to adapt different characters as an adaptation towards different food resources.

As a result, different populations evolved into different species with varied body size, beak shape, and feeding behavior.

11. Fill in the blanks to describe the similarities between transcription and DNA
Licemer1 [7]

Answer:

See the answer below

Explanation:

<em>Both transcription and DNA replication produce nucleic acids which are polymers of  (C, G, A, and T or U). Both processes depend on an  enzyme which adds one nucleotide at a time. </em>

<em>To  determine which nucleotide is added next, both transcription and DNA replication  use the nucleotide sequence in a  </em><em>template DNA</em><em> strand and the  </em><em>base pairing </em><em>rules.</em>

Transcription is a process through which RNA is synthesized using a DNA template. An enzyme known as RNA polymerase adds nucleotide bases to grow the RNA strand.

Replication is a process during which DNA makes a copy of itself. The double helix unwinds and each strand is used as a template to make a new strand. An enzyme known as DNA polymerase adds nucleotide bases to grow the new strands.

<u>In both transcription and replication process, the nucleotide sequence of the template DNA strand determines the which nucleotide will be added to the new RNA and DNA strands being synthesized according to the base pairing rule. Purine bases always pair with pyrimidine bases and more specifically, cytosine always pair with guanine while adenine always pair with thymine (uracil in RNA).</u>

The nutritional energy content (in Calories) present in 86g of broccoli with 2.6g of protein, 6g of carbohydrates, and 0.3g of f
Nimfa-mama [501]

Answer:

40 Cal

Explanation:

Data provided in the question:

Protein present in the broccoli = 2.6 g

Carbohydrates present in the broccoli = 6 g

Fat present in the broccoli = 0.3 g

Now,

We know,

Energy provided by protein and carbohydrates = 4 Cal / g

and,

Energy provided by Fats = 9 Cal / g

Therefore,

Total nutritional energy content = ∑(Amount × Energy provided)

= ( 2.6  × 4 ) + (6 × 4) + (0.3 × 9)

= 10.4 + 24 + 2.7

= 37.1 Cal    

rounding off the answer to nearest 5 ≈ 40 Cal

egoroff_w [7]
The correct answer among the choices provided is option A. Lung capillaries are responsible for exchanging carbon dioxide for oxygen from the air. Blood that comes from the heart gets oxygen from the alveoli. The carbon dioxide in the blood goes into the alveoli at the same time.

larisa [96]

Answer:

The second code in this case is the procedure for perfusion

Explanation:

Extracorporeal perfusion is the process of diverting the patient's blood via an artificial circulatory device to enable the gas exchange (oxygen absorbed, carbon dioxide removed) to take place. Only medical experts should handle this procedure so as to avoid any and all undesired scenarios or negligence towards patient care.
