Explanation:

The experimenter alters the independent variable with the hopes of collecting data about how the dependent variable changes in response.Other variables have to be controlled so that any changes of the dependent variable are attributed to the known independent variable.

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes.
UkoKoshka [18]

B.  New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

Explanation:

The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.

Cellular respiration is classified as an catabolic  process in which an energy rich substance is broken down into a lesser one.

  • Metabolic processes are usually divided into catabolic and anabolic processes.
  • In catabolic step, energy is broken down.
  • Cellular respiration is catabolic whereas photosynthesis is anabolic.
  • The new compounds formed have lower energy bonds after respiration.

Group the following into the appropriate range of measurement.
Vesna [10]

Answer:

Hydrogen atom & glucose molecule --- atomic.

Herpesvirus, DNA --- ultramicroscopic.

Protozoan, Rickettsia - microscopic.

Roundworm and algae --- macroscopic

Explanation:

1) Hydrogen atom & glucose molecule --- atomic.

The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.

2) Herpesvirus, DNA --- ultramicroscopic.

Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.

3) Protozoan, Rickettsia - microscopic.

Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is ( 10^3  \ \ to  \ \ 10^{10}), which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).

4) Roundworm and algae --- macroscopic

Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.

When a cell divides to make two new cells, it copies its DNA first. This is called DNA replication. Why do you think this is imp
Harlamova29_29 [7]

Answer:

DNA replication is important because without it, cell division could not occur. With DNA replication, the set of DNA of a cell can be duplicated and then each cell that results from division can have its own entire set of DNA, and cell division can theoretically continue indefinitely.
