Which events are associated with convergent boundaries? Check all that apply.

Biology
1 answer:
Sergio [31]3 years ago
8 0

Answer:

Creation of mid-ocean ridges, creation of new mountains, formation of earthquakes, and formation of volcanoes.

Explanation:

The convergent boundary plate tectonic comprises collisions between the continental and oceanic plates. The less dense and thinner oceanic plate gets overridden by the more denser and thicker continental plate. The ocean plate is forced down the mantle, and the event is called subduction.  

The magma found in the mantle leads to melting of the subduction plates. The magma gets within the plates via pores. This magma plate turns buoyant and moves in an upward direction. The molten magma leads to volcanic eruptions along with earthquakes. The solidification of magma in the subduction zone leads to the formation of ocean ridges. The formation of mountains close to the continents takes place when the magma after the volcanic eruption gets cooled and solidifies.

The largest and most complex mitochondrial genomes come from _____.
alexandr1967 [171]

Answer:

Angiosperm

Explanation:

The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.

It is least gene dense  as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.

A semi permeable bag (permeable to water but not to sucrose) contains a 2 % sucrose solution.
Burka [1]

Answer:

a) A beaker filled with 1 liter of deionized water?  - water will flow into the bag so its volume will increase. The solution is <u>hypotonic</u>

b) A beaker filled with 1 liter of 10% sucrose solution?  - water will flow out of the bag so its volume will reduce. The solution is <u>hypertonic</u>

c) A beaker filled with 1 liter of 2% sucrose solution - the volume of water in the bag will stay the same as the two solutions are in equilibrium. The solution is <u>isotonic</u>

Explanation:

Water moves by osmosis through a semi-permeable membrane. Osmosis describes the simple diffusion of water molecules.

Water molecules will move from a high concentration to a low concentration.

  • If the bag of 2% sucrose solution is placed in a beaker of deionized water, the concentration of water in the deionized water is in the beaker higher than in the bag (because the water in the bag contains 2% sucrose). Therefore, the water in the beaker will move from a high concentration outside the bag to a lower concentration inside the bag
  • If the bag of 2% sucrose solution is placed in a beaker of 10% sucrose solution, the concentration of water in the bag is higher than in the beaker (because there is more sucrose in the beaker). Therefore, the water in the bag will move from a higher concentration inside the bag to a lower concentration outside the bag.  
  • When the concentration of water is equal, the movment of water molecules reaches an equilibrium and there will be no change in the volume of water in the bag
