Answer:
The definition of trade off is an exchange where you give up one thing in order to get something else that you also desire. An example of a trade off is when you have to put up with a half hour commute in order to make more money.
Explanation:
Explanation:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.b This phase was formerly called the resting phase.
Answer:
What is the effect of power/magnification on the frequency and size of organelles under a microscope?
Explanation:
Organelles within the cell are responsible for carrying out various functions. Some cells are more specialized than others, and may have particular organelles at a higher frequency, or showing a variation in size; sub-cellular structures become more visible at higher magnifications under the microscope.
Hypotheses:
- organelle A's frequency decreases while B's frequency increases at higher magnifications
- organelle A's size increases while B's size decreases at higher magnifications
<em />
<em>Dependent variables: size and frequency cell organelles</em>
<em>Independent variable: power/magnification at low (x4), medium(x10) and high (x40)</em>
<em>Controlled variables: Type of organelles, microscope used, cell examined, </em>
Method:
1. Examine the organelles A and B in a cell mounted on a slide; use the fine adjustment to focus on the cell.
- Frequency: What is the average number of organelle A versus B, seen at low (x4), medium (x10) and high (x40) magnifications?
- Size: Measure the average diameter of organelle A versus B using an ocular micrometer at low, medium and high magnification.
2. Record and tabulate observations.
Answer:
If you have been to Venice (Italy), you have seen lagoons. In fact, the world lagoon is derived from a latin word <em><u>laguna</u></em>.
Principally, a lagoon is shallow water body which has been separated from the main water body due to sandbars, barrier islands, coral reefs,etc. However, sometimes, they includes other terms too such as bays, estuaries, sounds, or even lakes. They are of two types, i.e. Coastal Lagoons and Atoll Lagoons. In the figure attached, you can see how a lagoon looks like.
Answer:
This question lacks options, the options are:
A. chemical energy -> kinetic energy
B. kinetic energy -> solar energy
C. solar energy -> chemical energy
D. kinetic energy -> nuclear energy
The correct answer is A.
Explanation:
All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.
This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.
Note that, kinetic energy is the energy due to motion in the Chipmunk.
