Answer:
Gamete C
Explanation:
During the formation of gametes, the DNA is first duplicated, and 2 separate cell divisions take place to make a haploid cell.
In the first division, the homologous chromosomes are separated
Before the first cell division, the homologous chromosomes align in the centre. In this cell, the light green and dark green chromosomes align, as do the light purple and dark purple chromosomes. These are then separated into 2 different cells, 1 gets either the light or dark green chromosome and either the light purple and dark purple chromosome. The other cell also gets either light green or dark green and light purple or dark purple.
Then, a second division takes place that separates the sister chromatids to produce what we see in the gametes A, B, C, and D.
The only one that is not possible in a healthy cell is C, because it has not received any of the green chromosomes and instead has two homologous purples.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
I was able to check the image from other source. The answer should be "<span>Storage of needed components or cellular waste."</span>
Well count how many half lifes it would take to get from 1 to 0.125 first
1 to 0.5 - 1 half life
0.5 to 0.25 - 2nd half life
0.25 to 0.125 - 3rd half life
so essentially it would take 3 half lives to get to 0.125 kg of radium.
Now simply multiply the number of half lives with the half life value given
(3x1620) to get your answer as the number of years that it would take.
Hope this helps
Answer:
Processing and packaging of cellular materials prior to export
Explanation:
Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.
The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.
Answer:
2.compare a layer at one location to layers at other locations
Explanation:
Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.
Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.
