Answer:

Collagen fibers provides high tensile strength.

Explanation:

The extracellular matrix of connective tissue has three types of fibers: collagen, elastin and reticular fibers. Collagen fibers are sometimes called white fibers and are strong and resist stretching. These fibers are present in parallel bundles which in turn impart great tensile strength to the connective tissue.

Elastin fibers make a fibrous network in the matrix. Elastin fibers can be stretched up to 1.5 times their original length without breaking and resume the original shape after stretching. This ability of elastin fibers impart elasticity to the connective tissue. Reticular fibers also form the branched network in the extracellular matrix of the connective tissue.

Answer:

TRUE

Explanation:

Yes this is true that Complex DNA repair mechanisms in many organisms is a challenge to Darwinian evolution because DNA repair is complex involving many proteins and Darwinian evolution would need to evolve all of these proteins simultaneously. The importance of neutral mutations has emphasized by Evolutionary theory.

Genetically modified foods are derived from organisms with the _____ modified in some way that does not naturally occur.

Juliette [100K]

Answer:

The correct answer will be - DNA

Explanation:

The genetically modified food is the food crops produced by the modification of the genetic material or DNA of the organism.

Since the foods are produced by the modification of the genetic material which is DNA in almost all organisms therefore the foods are known as genetically modified organisms.

The modification includes the insertion and incorporation of the selected genes into organisms like resistance to stress conditions through vectors.

Thus, DNA is the correct answer.
