Answer:
1.27 hour or 77 minutes.
Explanation:
In the given question it is provided that:
1. DNA polymerase III synthesizes new DNA at a rate of- 1000 bases/sec
2. The genome of E.coli has- 4,600,000 base pairs
To calculate the time required for replication:
Total base pairs/ speed of enzyme
= 4600000/1000
= 4600 seconds
= 4600/3600 (1 hour= 3600 seconds)
= 1.27 hour or 77 minutes.
Thus, 1.27 hour or 77 minutes is correct.
Answer:
B. Nucleic acids store genetic information that codes for traits
Explanation:
There are four important biomolecules known which are also known as the molecules of life which are: carbohydrates, lipids, proteins and nucleic acid.
These all biomolecules play a very important role in the organism like the carbohydrates molecules provide energy to the cell, lipids provide a high amount of energy to the cell on oxidation, the proteins are the structural component of the skin, hair and nails.
In the given question, since only the function of the nucleic acid which is that it stores the genetic information which codes for the trait is correct therefore is the correct option.
Thus, Option-B is the correct answer.
Small intestine is the organ which has villi contains large surface area for absorption.
The small intestine has a tendency to be the region of finest absorption ability for most drugs due to its large surface region, the presence of both energetic and passive absorption mechanisms, and close to neutral pH.
But, about ninety five percent of nutrient molecules are absorbed inside the small intestine. The absorption of most people of these molecules takes area in the second a part of the small intestine, called the jejunum. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small gut into the mobile, then into the blood.
The small intestine is right for absorption since it has a huge inner surface location. That is shaped due to the plicae circulates which undertaking many tiny finger-like systems of tissue called villi. The character epithelial cells also have finger-like projections, which can be referred to as referred to as microvilli.
