Answer:
the outer layer of the star expands
Explanation:
Gravity pulls gas and dust together. A protostar forms as mass increases. A black hole forms as the core collapses.
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.
Answer:
Rhizobium is a bacterium that has positive effects on plant growth. Different strains display a wide range of effectiveness, from a little positive effect to a massive one. The strains used in the study did not show a positive effect promoting plant growth, so we could say that they ARE NOT Rhizobium strains and need to be properly identified.
Explanation:
Answer:
An interglacial period is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age.
