Answer: Two reasons that scientists isolate DNA are for genetic testing and body identification. Inside the nucleus of every cheek cell is DNA. "Lysis" is a Greek word that means "to cut." The purpose of the detergent in the lysis solution was to disrupt the cell membrane and the nuclear envelope so the DNA is released.
Explanation:
Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.
<u>Explanation:</u>
Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.
This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.
Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
The quantity of work done by the box is equal to 40 units of work.
<u>Given the following data:</u>
Distance = 4 meters.
Force = 10 Newton.
<h3>How to calculate work done.</h3>
In Science, work done is generally calculated by multiplying force and the vertical distance (displacement) that is covered by an object.
Mathematically, work done is given by the formula:
Work done = force × distance
Substituting the given parameters into the formula, we have;
Work done = 10 × 4
Work done = 40 units of work.
