Answer: 1. recollapsing universe
4. critical universe
3. coasting universe
2. accelerating universe
Explanation:
The universe is continually growing and galaxies are moving apart relative to one another.
These four models foresee the expansion and possible contraction of the universe.
Recollapsing universe: this model predicts that galaxies will stop growing apart and start getting closer to one another. It predicts that there is enough density to stop the growth of the universe in the future.
Critical universe: the universe has the same density as the critical density. This is the difference between the density the universe requires to stop and that of a universe with too little density to ever stop expanding
.
Coasting universe: has enough density to enable galaxies to keep growing apart
, in essence, less than the critical density.
Accelerating universe: this model explains that the distance of far-off galaxies is growing exponentially from an observer over time.
Answer:
Barycentre of planet lies at 1.068 radii.
Explanation:
- Jupiter is a Jovian planet and has mas of all rest of the planet combined and is 2.5 times as massive as other planet s and has a mass as similar to that of a brown dwarf.
- Jupiter lies about 1.068 solar radii from the Sun's center and scientists also suggest that Jupiter mass is shrinking due to the atmospheric variation by the sun.
difficult
Explanation:
The process of approving the constitution is best described as a difficult process. When a constitution is approved, it is said to be ratified. The ratification of a constitution is a very difficult procedure.
- A constitution is a set of laws or rules that governs a particular nation.
- Constitutions are usually drawn up by the legislative arm of the government.
- The legislatures are the lawmakers in a country.
- Constitutions of a nation takes several years to get approval due to diverse opinions that must be considered.

The gene expression of the organism may be affected by the environment. This includes the outside ecosphere where the entire creature and organism are situated or progresses, and also as the organism's interior ecosphere, these consist of the aspects of metabolism and hormones. Even though the structure of genes is unaffected by the environment, the gene expression (how the genes work) will be affected. Factors in the environment like drugs, foods, and toxins may result in some epigenetic changes by changing how the DNA bind by the molecules and the structure change of the proteins that the DNA wraps.
