What does a eukaryotic cell have that a prokaryotic cell theory?

2 answers:

7 0

Eukaryotic cells have organelles, membrane-bound structures that perform different functions in the cell, and prokaryotic cells do not. Some typical eukaryotic organelles include the nucleus, mitochondria, ribosomes, Golgi apparati and chloroplasts.

Which of the following is a true statement about lava that contains large amounts of dissolved gases? Lava that produces violent

anygoal [31]

Answer:

The dissolved gases produce violent eruption as they escape. 

Explanation:

Magma contains dissolved gases and these dissolved gases induce vapor pressure on the magma. The magma is able to remain in the dissolved state itself without erupting because this vapor pressure is less than the confining pressure of the rock surrounding the magma. 

One the vapor pressure exceeds this confining pressure the dissolved gases begin to expand and forms small gas bubbles.

The density of these gas bubbles called vesicles is less than the density of magma and thus naturally tries to push out. When the gas bubbles escape the magma is also pushed out. Thus greater amount of dissolved gases result in violent eruptions.

A 35 kg child moves with uniform circular motion while riding a horse on a carousel. The horse is 3.2 m from the carousel's axis

Andrews [41]

<h2>Hello!</h2>

The answer is:

b. $\frac{2.11m}{s^{2}}$

The centripetal acceleration or radial acceleration is present when an object is moving to describe a circular path. The centripetal acceleration is always perpendicular to the direction of the velocity and going inwards and towards the center.

The centripetal acceleration can be calculated using the following equation:

$CentripetalAcceleration=\frac{v^{2}}{RadiusOfMotion}$

From the statement we know that:

$v=TangentialSpeed=\frac{2.6m}{s} \\R=3.2m$

So, calculating we have:

$CentripetalAcceleration=\frac{{2.6^{2} \frac{m}{s} }}{3.2m}=\frac{{6.76\frac{m}{s} }}{3.2m}=\frac{2.11m}{s^{2} }$

So, the correct answer is:

b. $\frac{2.11m}{s^{2}}$

How are diffusion and active transport similar

adell [148]

Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.
