Answer:
Cheek cells lack a rigid cell wall and due to this their shape is not as well defined as a plant cell.
Explanation:
- Cell wall is the outermost structure in plant and bacterial cells.
- The plant cell wall is made up of cellulose and provide rigidity and shape to the cell.
- In animal cell, the cell wall is absent and the outermost part of the cell is the cell memrane.
- This is the reason that most animal cell lack rigidity and shape.
Does not affect organisms within an ecosystem
Answer:
The answer is A
Explanation:
You can tell that rocks are older or younger depending on if other layers overlap. B is the oldest because all the others cover it, C is the second youngest because D and A overlap it. From what I could tell, when I took the test, it was either A or D, neither overlap each other so I was not sure so I guessed A and got it right. Though it could be looked at that A is smaller than D since its still growing and building.
Answer:
The correct answer would be a) 3,5, and 10 g samples of liver.
Independent variable in any experiment refers to the variable which is being kept controlled or changed to check its effect on the dependent variable.
In contrast, the dependent variable is the one whose value depends on the independent variable.
For example, in the given hypothesis the rate of a reaction depends upon the amount of enzyme catalase.
Thus, amount of enzyme or its source (liver) forms the independent variable and the rate of reaction forms the dependent variable.
No because the bacteria thrives of of its natural environment
