what is opposite of whiskers
Some organelles that are visible in the cell include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and vacuoles. These organelles can be observed under a light microscope due to their size and distinct structures.
It means that the observed values in the experiment all exactly match the expected values. That is unlikely, unless the experiment was "fixed".
First of all, they're not called organs. they are called organelles. And no, they cannot. a plant needs organelles just as much as you need your organs.
Robert Hooke observed and named cells, the basic unit of all living organisms. He also saw cell walls, vacuoles, and nuclei within the cells he observed using a microscope.
The variable is the thing that changes - there are literally an infinite number of possible variables so they cannot be listed. Each experiment has its own variable.
Red blood cells are considered cells, but they lack all organelles. Red blood cells cannot divide or replicate like other cells of the body.
no
The experiment is called a controlled experiment. In this type of experiment, all variables are kept constant across experimental groups, except for the independent variable, which is deliberately manipulated to observe its effect on the dependent variable. This design helps to ensure that any observed changes can be attributed solely to the manipulation of the independent variable.
* independent variable:in an experiment there is only one variable and its set by the person carrying out the experiment . * dependent variable: measured in all set ups during the investigation. * controlled variables: are quantities that the scientist wants to keep constant. so , the part of the experiment that does not depend on the variable is the controlled variable.
All eukaryotic cells have a membrane-bound nucleus and other membrane-bound organelles.
all of them, bacteria have no organelles
Conditions in an experiment that are the same for all groups are known as controlled variables. These include factors such as temperature, time, equipment, and environmental conditions that could influence the outcome of the experiment. By keeping these conditions constant, researchers can ensure that any observed effects are due to the independent variable being tested, rather than external influences. This helps to enhance the reliability and validity of the experiment's results.
