At pupal stage silkworms are killed to get fibres .Why give reason ?​

Answers

Answer 1

Answer:

But in the fabric industry, silk is mass produced through the breeding and domestication of silkworms on what are essentially moth factory farms. When the caterpillars enter the pupa stage of their development, their cocoons are plunged into boiling water. This kills the silkworms and begins to unravel the longer fibers.

Explanation:

Answer 2

Answer: In the life cycle of the silkworm the silkworm is killed at the stage of pupa because pupa is covered with silk and we kill silkworm to obtain silk fibres from them.

The marine biologist from the nursery is planning to develop a large number of new coral polyps with large stinging tentacles. Identify the type of reproduction the marine biologist should use to develop the new coral and explain why this type of reproduction is preferable.

Answers

Answer:

Sexual reproduction.

Explanation:

Sexual type of reproduction used by the marine biologist in order to develop the new coral because variations in an organisms only be done with sexual reproduction. For producing new type of coral, the type of corals should be fused together in order to gain the desire characters in the organisms. So if the marine biologist want coral polyps with large stinging tentacles, sexual reproduction is the only way. From asexual reproduction, the offspring produce identical to parents so that's why we can't use asexual reproduction.

Cytokinesis, Mitosis, Interphase.

Cytokinesis, Interphase, Mitosis

Mitosis, Cytokinesis, Interphase

Interphase, Mitosis, Cytokinesis

Answers

Answer:

my best guess would be

Interphase, Mitosis, Cytokinesis

Explanation:

Interphase - stage where the cell prepares for Mitosis. During this stage the cell grows and replicates DNA.

Mitosis - part where the chromosomes are separated and are separated into 2 nuclei.

Cytokinesis - part where cells officially splits into two daughter cells.

Cell cycles are events that involve various series of steps for the cell to grow. It follows the order of interphase, mitosis, and cytokinesis. Thus, option D is correct.

What is the cell cycle?

The cell cycle is an important part of the growth and cell division of the eukaryotic cell. It includes interphase comprising the G₁, S (synthesis/replication), and G₂ phase, mitotic phase, followed by cytokinesis and G₀ phase.

The cell spends the majority of its time in interphase where the genetic material undergoes preparations and gets duplicated for the further process. In mitotic division the actual division of the organelles and the nucleic acid takes place.

Mitosis is followed by cytokinesis where the cytoplasm of the cell gets separated to form two daughter cells after the telophase stage. The cell then undergoes the G₀ phase which is the quiescent stage of the cell division where no cell division occurs.

Therefore, option D. interphase, mitosis, and cytokinesis are the correct order of the cell cycle.

Which of the following examples come from renewable natural resources

Answers

Answer:

Milk, Leather, Paper, Cardboard

Explanation:

Milk, leather, paper, and cardboard all come from natural resources for the largest part:

Milk - Cows

Leather - Animal hide

Paper - Trees

Cardboard - Recycled paper

All of the mentioned are renewable because cows can breed, hide can be found on many animals, trees easily grow everywhere, and cardboard is made from recycled paper (which comes from trees).

Uranium, tin, iron, plastic, steel, and gold aren't renewable and (most of them) do not come from natural resources. Uranium is rare and only found in a limited source around the world, as well as other metals (tin, iron, steel, gold). As for plastic? Plastic is not natural nor renewable because it's created by man. All of the above mentioned (besides the answer) also takes thousands of millions of years to degrade naturally.
