What happens when removing and organism from a food chain?
kondor19780726 [428]

Answer:

It depends on whether or not the organism is a producer or a predator. If the organism removed is a producer, every other organism that relies on said producer for food will not be able to survive. If the organism removed is a predator, the organisms that said predator eats will flourish, diminishing the natural resources in the ecosystem and inevitably starving the population of the ecosystem.

How many neutrons does element X have if its atomic number is 41 and its mass number is 162?
bekas [8.4K]
Isn't this Chemistry.... But anyways am a budding Biochemist

        (Mass #) = (Atomic #) + (Neutron #)
: . (Neutron #) = (Mass #) - (Atomic #)
                       = 162 - 41
                       = 121

Note that: Atomic # = Amount of Protons = Amount of Electrons

Describe what is happening in each stage and what each stage looks like:
natima [27]
Prophase is the first phase is when the two sister chromatids pair up and the nucleoli disappears. Prometaphase is the second phase where the microtubules begin to separate from each other, each pair of microtubules attach to the kinetochores and some nonkinetohore microtubules interact with those from the opposite pole of the spindle. Metaphase is the third phase where the chromosomes are lined up on the invisible line of the metaphase plate. Anaphase is the fourth phase where the two daughter chromosomes begin to separate from each other to opposite poles. Telophase is the last phase where the two daughter nuclei form creating two identical nuclei.

3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks.
Over [174]

Answer:

This question is asking to identify the following:

Independent variable: Different humidity levels

Dependent variable: Height of the plant

Control group: Tree left outside in normal conditions

Controlled variable: same time of measurements (once in a week), same types of trees

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, three redwood trees are kept at different humidity levels. Hence, the independent variable is the DIFFERENT HUMIDITY LEVELS the redwood trees were kept at.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this case, the HEIGHTS of the trees measured is the dependent variable.

Controlled variable or constants are those variables that must be kept unchanged throughout the experiment for all groups. In this experiment, the constants are: same time of measurements (once in a week), same types of trees (redwood).

Control group is the the group in an experiment that does not receive experimental treatment. In this case, the group that does not receive treatment/control group is: Tree left outside in normal conditions.
