Explanation

Jellyfish have no skeleton.

Jellyfish are free-swimming marine animals with a gelatinous bell and trailing tentacles. 

Explanation

This linear, elastic relationship between stress and strain is known as Hooke's Law.

If you plot stress versus strain, for small strains this graph will be linear,

and the slope of the line will be a property of the material known as Young's Elastic Modulus.

Explanation

• Epigeal germination occurs in dicotyledonous seeds (Dicot Seed).
• Where the cotyledon emerges from the seed coat and grows above the soil surface.
• Examples of dicot seeds include beans, peas, and tomatoes.

Explanation

• Decreased industrial activity can lead to a reduction in pollution levels.
• As fewer pollutants are released into the environment.

Explanation

In incomplete dominance, the heterozygous phenotype is intermediate between the two homozygous phenotypes.

The F2 generation from a cross between two heterozygotes will show a 1:2:1 phenotypic ratio, where one part shows the dominant trait, two parts show the intermediate trait, and one part shows the recessive trait.

Explanation

Two matrices are equal if and only if they have the same order and corresponding elements are equal.

Explanation

Materials that allow most all light to pass through them are called transparent. Examples of transparent items are glass, water, and air.

Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper. If an object does not allow any light to pass through it then it is opaque.

Explanation

The Arctic Circle is one of the two polar circles and the most northerly of the five major circles of latitude as shown on maps of Earth.

Explanation
