a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages

elena-s [515]

Answer:

75years

Explanation:

Let the Father's age be represented by 2x

Let the Son's age be represented by x

Five years ago;

Man's age will be = 2x - 5

Son's age will be = x - 5

If the ratio of their ages five years ago was 9:4, then;

2x - 5/x-5 = 9/4

4(2x - 5) = 9(x - 5)

8x - 20 = 9x - 45

- Collect like terms

-20 + 45 = 9x - 8x

25 = x

Hence, the son's age = 25 years

If x = 25, the father's age (2x) will be 2 × 25 = 50years

The sum of their ages will be = 25years + 50years = 75years

In proteins, secondary, tertiary, and quaternary levels of structure depend on the primary structure.

Fittoniya [83]

Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.

Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.

Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones

Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.

Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.

Urochordates, commonly known as sea squirts have a larval stage that resembles a chordate.

What are Urochordates? Give the characteristics of it.

Ascidians (sea squirts) are a common term for the Urochordata, also known as the Tunicata. The body of an adult tunicate is fairly simple. While possessing all the characteristics of a chordate, including a notochord, a dorsal nerve cord, pharyngeal slits, and the larva of many tunicates swims freely and lacks only these characteristics. Ascidia, Salpa, and Doliolum, for instance.

Characteristics features of Urochordata:

1. The grownups are anchored to the foundation.

2. It is also known as "Tunicate" because an adult's body is covered by a tunic formed of tunicin, a cellulose-like substance.

3. The notochord only appears in the larval stage and vanishes in the adult.

4. In adults, a dorsal ganglion takes the role of the nerve cord that is present in the larva.

5. The larva can migrate and changes into a different animal.
