Answer:
According to the illustration of meiosis I, when sister chromatids stay together the phase to which it corresponds is telophase I (fourth option).
Explanation:
Meisois is a process of cell division whose final result is the obtention of two daughter cells with half of their genetic charge, with respect to the original cell. This process is divided into two parts, called meiosis I and II.
Telophase I corresponds to the phase of cell division in meiosis I, where the events that occur are the appearance of the nuclear membrane on the newly divided genetic material, cytokinesis -or cytoplasmic division- and above all due to the fact that each daughter cell already contains half of the genetic load, since the sister chromatids stay together.

Change in gene frequency of ancient cockroaches led to the evolution of modern cockroaches.
The light red layer between the white lumen and blue lamina propria consist of epithelium cells.
<h3>What is a lamina propria?</h3>
A lamina propria is a type of connective tissue that is present and found under the thin layer of tissues covering a mucous membrane.
<h3 /><h3>Characteristics of the lamina propria</h3>
- It is a very large layer of connective tissue
- It divides the innermost layer from a layer of smooth muscle tissue.
- it is a light red layer barrier located between the white lumen and blue lamina.
- It is made up of epithelium cells.
- It is also found in the respiratory tract, the Gastrointestinal tract, and the urogenital tract.
Thus, the light red layer between the white lumen and blue lamina propria consist of epithelium cells.

Answer:
Phenotypic changes:
When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.
It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.
Evolutionary processes:
It's natural selection that allows the fittest organism to survive. As in the case of the mutants
Answer:
Osmosis is a process in which molecules pass from semipermeable membrane.
Explanation:
Osmosis is a biological process. The solvent molecules pass through semipermeable membrane and then solute particles move through the membrane with the help of water. These molecules are not capable of passing through the membrane in absence of water.
