The four main biological macromolecules are lipids, proteins, nucleic acids, and carbohydrates. The term "macronutrient" particularly refers to the macromolecules that give the organism its nutritional energy.
<h3>What are biological macromolecules?</h3>
Large, naturally occurring cellular components known as biological macromolecules perform a variety of vital tasks for the development and survival of living things. There are four significant categories of biological macromolecules: lipids, proteins, nucleic acids, and carbohydrates.
Proteins, nucleic acids, and polysaccharides are typical examples of macromolecules.
Macromolecules are enormous molecules that fill a cell and give it vital life-sustaining activities. Macromolecules, for instance, offer structural support, serve as a reservoir for stored energy, have the capacity to store and retrieve genetic information, and can speed up biological operations.

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare.
Answer:
<h2>5 minutes
</h2>
Explanation:
1. In bidirectional replication; there are two replication forks, and each proceeding at a rate of 100,000 (as given in the question) nucleotides per minute.
2. So, by the given rate of replication, we can calculate that, it would require 5 minutes for the circular DNA molecule to be replicated by bidirectional replication because each fork synthesize 500,000 nucleotides in 5 minutes ( 100,000 per minute) ( as given, in 5 minutes × 100,000 nucleotides per minute= 500,000 and by 2 forks= 1,000,000) within the time period.
The size and position of their centres are the same for homologous Chromosomes
Air pressure (inside the lungs) is lowest when lung volume is highest, so the answer is B. when you breathe in your lungs expand, which makes the air molecules spread out, therefore the pressure is lower.
