Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).
Hope this helps!
<span>Parent cell gives rise to all the formed elements of the blood that too in seven different types from a single parent cell. The process of generating the formed elements is called as hemopoiesis. Parent cells are part of Pluripotent Stem Cells.</span>
The genes are from the nuclei of the egg (from the female) and the sperm (from the male) the different traits are joined to create the particular genes.
(I might be right.)
<span>Pacinian corpuscles are rapidly adapting mechanoreceptors so they respond only at the onset and offset of the stimulus. The Pacinian corpuscle has a single afferent nerve fiber. Its end is covered by a sensitive receptor membrane whose sodium channels will open when the membrane is deformed in any way. Pressure thus causes sodium to enter the neuron and create a generator potential. If this potential reaches a certain threshold nerve impulses are formed. This impulse is now transferred along the axon with the use of sodium channels and sodium/potassium pumps in the axon membrane. The magnitude of the stimulus is encoded in the frequency of impulses generated in the neuron. So the more massive or rapid the deformation of a single corpuscle, the higher the frequency of nerve impulses generated in its neuron.</span>
Answer:
1). chloroplast
2). cell wall
Explanation:
1). the chloroplast is the pigment that makes plants greenish, therefore animals cannot have green pigments as they are not all green and they do not need chloroplast in their cells
