Answer:

The correct answer will be option-B

Explanation:

Three types of solution are formed based on the concentration of the solute which are:

1. High solute concentration- Hypertonic solution

2. Low solute concentration- Hypotonic solution

3. Equal solute concentration- Isotonic solution

When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.

If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.

Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.

A cell with 80 chromosomes undergoes meiosis. How many chromosomes are found in the daughter cells? How many daughter cells are
qwelly [4]

Answer:

Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.

Explanation:

Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.

Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.

Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.

Give a brief explanation of why food webs are preferred over food chains for representing the flow of energy in an ecosystem.
olga nikolaevna [1]
<h3><u>The Food webs are preferred over food chains for representing the flow of energy in an ecosystem for the following reasons: </u></h3>
  • The food webs are higher in complexity when compared to food chains and also, in food web, more than one primary producers is present which increases the 'flow of energy' in the ecosystem.
  • Food web represents the real life better than the food chains do.
  • Food web shows many different paths through which the organisms can be connected.
