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.

Why do we want to turn genes off or on?

Dmitrij [34]

The process of turning off and on of genes is known as gene regulation.

Explanation:

When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.

The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.

Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.

Function in the cell cycle. Explain why interphase is important before mitosis begins.

Luda [366]

Answer:

During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

A recent study of the marine hawksbill turtle's stomach contents revealed that sponges constitute a major portion of their diet.

bearhunter [10]

Answer:

These structures that protect the sponges from most predators, but not turtles, are spicules.

Explanation:

Sponges skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.

There are different kinds of spicules:

- Monoaxonic spicule: needle-shaped, straights or curves

- Tetraxonic spicules: they have four prolongations

- Triaxonic or Hexaxonic spicules

- Poliaxonic spicules

Two terms can be applied to any of these spicules kinds:

- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton

- Microspicules: Variable in shape and size, with ancillary functions

Sponges have few predators thank to the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
