The endosymbiotic theory proposes that eukaryotic cells arose as a result of large cells engulfing smaller, aerobic bacteria. th
lina2011 [118]

The organelle that provides evidence for this theory is the mitochondria and the chloroplast.

<h3>What is the endosymbiotic theory?</h3>

The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.

In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled  the cells to meet their needs for survival an growth.

The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.

In conclusion the endosymbiotic theory describes  how eukaryotic cells arose from simple prokaryotic cells.

Explain the importance of geoneutrinos to understanding earth’s interior
otez555 [7]

Answer:

“Geoneutrinos,” neutrinos that stream naturally from the Earth’s interior, are giving scientists the best direct evidence of what’s at work in the belly of the planet. Released by naturally occurring radioactive isotopes inside the Earth, geoneutrinos carry information about what makes the Earth’s insides hot; what elements make up the core of our planet and in what concentration and distribution; how the Earth’s mantle and tectonic plates move and interact; and how planets like our own form and evolve.

LekaFEV [45]

Answer:D.D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.

Explanation

Options A-C are correct except D.

→Increase in Telomere length is indicative of abnormal growth, cancer cells can reactive  telomerase to increase cell's length.

→Once a monolayer is reached; this a stage of  a complete normal cell division , a cell that goes beyond this stage must be mutated. assuming all other factors are constant .

Uncontrolled cell division is an indication of virulent growth in mutated cells.

<u>Cancer cell requires a ,medium of  living host to thrive, alga medium will not support growth for carcinoma cells -the correct answer. </u>

<u></u>

Completed Que.

:Imagine that you are a graduate student working in a cancer lab. You accidentally mix unlabeled tubes of carcinoma cells with tubes of normal epithelial cells. Which of the following is NOT a possible strategy to allow you to distinguish which tubes contain carcinoma cells?

A.)Monitor telomere length over time during multiple cell divisions.

B.) Plate the cells in culture and look for the culture that stops dividing once a monolayer is reached.

C.) Monitor the rate of cell division.

D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.

1. When a sugary gummy bear is placed in water, there are more dissolved solutes _______________ (inside/outside) the gummy bear
madreJ [45]

Answer:

When a sugary gummy bear is placed in water, there are more dissolved solutes inside the gummy bear.

Explanation:

The sugary gummy bear has more solutes as compared to the water in which it is being soaked. When a sugary gummy bear is placed in water, water enters the gummy bear through osmosis as water tends to move to the place where there are more solutes. The sugar gummy bear has more solutes. So, the gummy bear  expands and increases in size due to the entrance of water into it.
