a. Develop a hypothesis related to the human body. b. Describe the independent variable. c. Describe the dependent variable. d. Describe the control variable (group). What is systematic observations in biology? Explain how genotypes and phenotypes of the parents and offspring...
In a research study, it is often required to determine the possible impact of one or more independent variables on a dependent variable. To maintain the validity of the results, scientists keep certain variables in check, known as the control variables, ensuring they do not influence the study ...

The mean angle of pitch motion of the fin is used as a control variable. A computational-fluid-dynamics-based parameterisation of the fin forces is used for control system design. A robust servo regulator for the control of the depth of the vehicle, based on the non-linear internal model...
There are several additional types of networks such as Bayesian nets, which combine directed acyclic graphs with a conditional distribution for each random variable (vertices in a graph, e.g., [75.44]), and signed directed graphs, in which a signed directed edge is used to represent activation...
Next, one or two (for simultaneous bilateral recordings) four-shank Neuropixels 2.0 probes mounted on a multi-probe manipulator system (New Scale Technologies) and controlled by SpikeGLX software (Janelia Research Campus) were inserted through the craniotomies at variable angles (0–20°) depending...

coli) is variable, but only between two similar hydrophobic amino acids (leucine and isoleucine) that are both known to allow TLR5 binding74. The exception that helps prove the rule is H. pylori flagellin which is not recognised by TLR5 and differs from the other species at three of the ...
2008). Natural enemies tend to enhance or have no significant effect on the initial spread of non-persistently transmitted viruses under controlled conditions, but the outcome seems to be largely variable with each natural enemy-vector interaction. The lack of studies for semi-persistently transmitted...
Broadscale dampening of uncertainty adjustment in the aging brain Reduced flexibility is a hallmark of cognitive ageing. Here, the authors examine EEG, fMRI and pupillometry signatures to show that older adults adapt less to variable uncertainty and identify neural mechanisms that support uncertainty ...
