The correct answer is A. Sunspots

Explanation:

The Sun is the star that is the center of the Solar system where Earth is located and that is mainly composed of hydrogen, helium and other elements such as oxygen, carbon or iron. In terms of the photosphere or the outer shell of the Sun this is a plasma layer that is mainly observed as uniform in color, but also presents dark areas that are called sunspots, these are cooler areas in the surface of the sun that exist as a result of the magnetic field of the sun; additionally, this can appear individually or in groups which are called Sunspot Groups. Therefore, the dark, cooler areas on the sun's surface are called Sunspots.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.

<h3>Explanation:</h3>

The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.

The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.

Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.

In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.
