Because both eat primary consumers.
Question: Below is a list of functions performed by organisms. Examine the list, then answer the question that follows.
gas exchange
intake of nutrients
disposal of wastes
stimulus response
reproduction
How do these functions compare between single-celled and multi-celled organisms?
A. Single-celled organisms can perform all of these functions, while multi-celled organisms can perform only some of these functions.
B. Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
C. Single-celled organisms can perform only some of these functions, while multi-celled organisms can perform all of these functions.
D. Neither single-celled organisms nor multi-celled organisms can perform all of these necessary functions.
Answer:
Option B, Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
Explanation:
All these functions are performed by both single celled and multi-cellular organism. A single cell has several microscopic organelles that performs specific functions while a multi - celled organism has different body organs/tissues to perform specialized function separately.
A cell exchange gas through the cellular membrane, intake nutrients through engulfing, dispose waste by lysosomes, stimulus response by sensory hairy structure and reproduction through cell division
Hence, option B is correct.
Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead
Out of the choices given, the conclusion that can be made is that in both cases, societies were brought into contact through trade. The cultural exchanges that went along with that trade enriched those societies. The correct answer is C.
Answer:
The diameter of the xylem vessels should be small in order for the capillary action to take place.
Explanation:
The vessels through which water is transported to different parts of the plants and trees are the xylem. Water is transported in the trees through a mechanism named as capillary action. This mechanism can occur only if the diameter of the vessels are small.
The water molecules adhere to the walls of xylem and an upward force is generated. If the diameter of the vessels i.e xylem would be small then the surface tension between the xylem and water molecules would be enough to move the water in an upward direction.
