What causes sea floor to spread apart at mid ocean ridges?

Biology
1 answer:
Nataly [62]3 years ago
8 0

Answer:

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.

The answer is reflexes. Reflexes are usually involuntary muscle movements that happen almost instantaneously in response to stimuli. A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain. It is a survival mechanism evolved by the body used in the objective to escape danger.

Eva8 [605]

Answer:

The correct answer would be the harmless bacteria had been transformed.

Griffith used two different strains of the bacteria <em>Streptococcus pneumoniae - </em>type-III-S or smooth strain and type II-R or rough strain.

Smooth strain had protective covering around itself (protect itself from hosts's immune system) and was able to kill the mice.

Rough strain did not have any protective covering around itself  and thus could be easily removed by the immune system Hence, it was not able to kill the mice.

In addition, heat killed smooth strain was also not able to kill the mice. However, when remains of it was added with rough strain then the blend was able to kill the mice.

Lastly, he was able to isolate living bacteria of both the strains.

He concluded that non-lethal type II-R strain was transformed into lethal type II-S strain by "transforming principle" (which we know today as DNA) that was supposed to be the part of dead III-S strain bacteria.

Gennadij [26K]

Answer:

B.sea floor spreading

Explanation:

The creation of new crusts at the middle of the mid- ocean ridges is also sea floor spreading.

The process of sea floor spreading entails the creation of new crusts at the margin of the oceanic crusts.

Basaltic materials from the subsurface upwells to the surface.

They cool and solidifies to form new crusts. The old crust is moved behind and away from the margin. This way, sea floor is formed and it spreads in like manner.

At this margin sea floor is created and at a convergent margin, it is destroyed.

Factors<br> Increase or Decrease<br> in Carrying Capacity?
ale4655 [162]

Answer:

Carrying capacity, or the greatest number of people that an environment can support over time without harming or degrading it, is controlled by a few basic factors: food supply, water availability, and space.

Which is not a major difference in the organization or content of prokaryotic and eukaryotic genomes?
bulgar [2K]

Answer:

All of the above are true

Explanation:

Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:

- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.

- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.

- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.

- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.

Based on this, all of the above options are TRUE
