<u>Answer</u>: C) Hydrophobic interior, hydrophilic exterior

<u>Explanation</u>:

  • The <em>plasma membrane</em> of the cell defines its boundary and separates its internal components from the external environment.
  • The basic components of the plasma membrane include phospholipids, carbohydrates, proteins, and cholesterol.
  • The plasma membrane is a phospholipid bilayer, with <em>hydrophobic</em> tails of the phospholipid projecting <em>inwards</em> and the <em>hydrophilic</em> exterior in contact with the external environment.
  • <em>Due to this, the plasma membrane has a hydrophobic interior and hydrophilic exterior. </em>

Firdavs [7]

Answer:

the time that cell spend in prophase is 30 minutes

Explanation:

The computation is shown below:

= Number of cell ÷ sample

= 25 ÷ 100

= 1 ÷ 4

Now it takes two hours

So,

= 1 ÷ 4 × 2 hours

= 0.5

This 0.5 represent the 30 minutes

Hence, the time that cell spend in prophase is 30 minutes

__________________ dating involves age-dating fossils with known time periods grouped into four eras that represent distinct age
RSB [31]

According to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.

<h3>What is Relative dating?</h3>

It consists of ordering fossils or events in a proper formation sequence from the oldest to the most modern, it tends to be used as a method for making chronologies, the ordering of events, fossils or rocks.

Since it does not give an exact or approximate date, they can only give us a fairly long period of time, or in their case a temporal ordering of the fossils.

Therefore, we can conclude that according to the research,  the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.
