In the nebular hypothesis, why did the nebula start to collapse?

Biology
1 answer:
sergeinik [125]2 years ago
6 0

Answer:

The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

1. The plant life that is characteristic of a biome depends upon:
eimsori [14]

Answer:

D. all of the above​

Explanation:

Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.  

For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.

Would a bacterial cell undergo mitosis in the same way as a eukaryotic cell? Why or why not?
nikklg [1K]
Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm.

Next the researchers repeated the experiment in part c but instead of mixing the ax and ay strains, they put one strain on each
Nadya [2.5K]
The correct answer is none of the above.

Bacterial cells can transfer genetic material through a process called bacterial conjugation. This process involves the direct physical contact of the bacterial cells and a horizontal gene transfer. The genes which are transferred are most of the times beneficial for the recipient, such as genes for antibiotic resistance.

In this example, bacterial cells cannot have physical contact, since they are separated by a glass filter. Therefore, the bacterial conjugation cannot happen. Given that no gene transfer can be achieved, the AY strain remains bio- trp- and is unable to grow on any medium that lacks bio or/and trp.
