A student wants to investigate how adding fertilizer affects the growth of flowering plants. She gathers 10 identical flowering plants and divides them into two groups of five plants. One group receives the same amount of fertilizer at the same time each day for four weeks. The other group does not receive fertilizer. All plants in both groups are kept at the same temperature and given the same amount of water and light every day for four weeks. The growth of the plants after four weeks what would be the independent variable , dependent variable, hypothesis, and 3 controls no

Answers

Answer 1

Independent Variable: Fertilizer

Dependent Variable: Plant Growth

Hypothesis: Giving plants fertilizer will help them grow faster than plants with no fertilizer.

Controls: Type of plant, watering routine, temperatures, amount of sunlight.

Explanation:

Independent variable always modifies the dependent variable.

Dependent variable always changes based off of the independent variable.

The hypothesis must be a statement that can be tested with an experiment.

Control variables should stay the same throughout the experiment in order for the experiment to be testable and accurate.

a hypothesis that has support to back it up and is yet to be disproved

Answers

Answer:

a theory

Explanation:

A hypothesis that has support to back it up and that is yet to be disproved can be referred to as a theory.

Ordinarily, a hypothesis is a tentative statement that has not been proven in any way. Once a hypothesis has supports to back it up and there are no counter-evidence to disprove it, it becomes a theory.

In other words, a theory is a proven hypothesis and it remains so until there are overwhelming evidence to counter the supporting evidence.

Using the formula in your notes, calculate the growth rate for a population of 1,200 with a carrying capacity (K) of 2,000 and a maximum per capita growth rate (rmax) of 0.3.

Answers

Answer:

The correct answer is : 144.

Explanation:

Given:

K or carrying capacity = 2000

N or population size = 1200

rmax or maximum per capita growth rate = 0.3

formula:

growth rate = [tex](rmax) (N) \frac{K-N}{K}[/tex]

Solution:

by the formula ,

growth rate =

[tex](0.3) (1200) \frac{2000-1200}{2000}[/tex]

= [tex]360 [\frac{800}{2000}][/tex]

= 360 × 0.4

= 144

Thus, the correct answer is : 144.

The central nervous system includes all of the following except: brain spinal cord nerves that reach the tissues in limbs cerebellum

Answers

Answer:

My answer is the CNS consist of the brain and the spinal cord nerves but not cerebellum.

The nerves that reach the tissues in limbs is not the part of the central nervous system.  

• The central nervous system or the CNS mainly is formed of the spinal cord and the brain. However, it generally is considered to exhibit seven fundamental parts, that is, the spinal cord, the pons, the medulla, the midbrain, the cerebellum, the cerebral hemispheres, and the diencephalon.  

• The parts of the nervous system apart from the brain and the spinal cord is known as the peripheral nervous system.  

• It comprises the spinal nerves, the cranial nerves and their roots and branches, the neuromuscular junctions, and the peripheral nerves.  

• The bundles of axons or the nerve fibers transmit information to and from the central nervous system in the peripheral nervous system.  

Thus, the nerves that reach the tissues in the limbs is the part of peripheral nervous system not central nervous system.

Why do field researchers and laboratory researchers use tools that are similar and tools that are different

Answers

Answer:

Please see below

Explanation:

These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.

Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.

How does the distance from this eye chart affect the number of letters visible on a line? What factor of the experiment is the eye chart? Control Group, Control Variable, Independent variable, or Dependent variable

Answers

Answer:

This question is asking to identify the variable in the experimental statement.

The eye chart is the CONTROL VARIABLE

Explanation:

An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.

A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.

N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.
