Answer:

Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium. The production of new elements via nuclear reactions is called nucleosynthesis. A star's mass determines what other type of nucleosynthesis occurs in its core (or during explosive changes in its life cycle).

Number the following steps in the correct order and tell which stage it occurs in:
Sedaia [141]

Answer:

The correct answer is given below:

Explanation:

1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis.  During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.

2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane

3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.

4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase  

5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase.  During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.

"Bt maize"
Maurinko [17]

The correct is option (C) includes bacterial genes that produce a toxin that reduces damage from insect pests.

Due to advancements in plant biology, some plant species can now incorporate unique traits that are typically not found in their species. New and improved plant strains can be created using plant biotechnology. This technology is heavily utilized to advance agriculture.

A particular crystalline insecticidal protein is created by combining a specific gene sequence from the bacteria Bacillus thuringiensis with plants. Bt plant is a common name for these transgenic plants. One such transgenic plant that protects transgenic maize from damaging insects and pests is bt maize.
