The branch of biology dealing with interactions along organisms and between organisms and their environment is called Ecology, I believe.
The answer is C. Output device
Answer:
Th correct answer is A. Capsid
Explanation:
T-2 phage is a bacteriophage which is virulent to E.coli which means T2 phage infects E.coli. The genetic material of T2 phage is linear DNA which is double-stranded. The genetic material of T2 phage is enclosed in a protein coat which is called capsid.
This capsid protects the genetic material of bacteriophage by any enzymatic digestion, helps the virus to attach the host cell and helps the virion to penetrate the cell membrane of the host cell and inject its genetic material in the host cell. Therefore capsid is the correct answer.
Answer:
The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.
Explanation:
The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.
1. Answer;
1000 times
If the surface area of a cell that is shaped like a cube increases 100 times, its volume increases about 1000 times.
Explanation;
If the surface are increases 100 times it means that the side of a cube has increased by a scale factor of 10, therefore, the volume of the cube will increase about 1000 times ( 10 × 10 × 10 = 1000).
2. Answer;
Moving needed materials in and waste products out.
Explanation;
Large cells have more trouble moving materials that are needed in the cell and wastes products out of the cell, as compared to small cells.
The volume of large cells is so large, the surface area, by comparison, is relatively small, thus large cells have a small surface are to volume ratio, compared to small cells which have a large surface area to volume ratio, which makes the transportation of substances into and out of the cells extremely efficient compared to large cell.
