Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
Explanation:
1) Arithmetic density- the number of people per square unit of land
2) Physiologic density- Is the number of people per square unit of farmland.
3) Agricultural density- is the number farmers per unit of farmland.
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.
