Answer:
Either the color will disappear or the brightness of the color will reduce as compared to the brightness in normal case.
Explanation:
Non diffusible red pigment known as prodigiosin is a characteristics of S. Marcescens. Since, the red pigment is dependent on least 10 enzymes, it is clear that the pH and temperature range must be adequate for these enzymes to be functional. The optimum condition for pigment formation is 30 degree temperature and alkaline medium.
If any of the 10 enzymes become non-functional, the chances of attaining normal bright red color are not possible. Either the color will disappear or the brightness of the color will reduce as compared to the brightness in normal case.
Independent: ____________
Dependent:___________
3. What is a negative control you should use to rule out alternative explanations for a positive result?
4. In Parts 2 and 4, you measured the diameter of the micronucleus using fluorescence microscopy and electron microscopy. How do the measurements compare? Which of the two types of microscopy above do you believe was most accurate? Why?
Phagocytosis queries are given detailed in the following way
Explanation:
1.Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it.Phagocytosis differs from other methods of endocytosis because it is very specific and depends on the cell being able to bind to the item it wants to engulf by way of cell surface receptors. Phagocytosis won’t happen unless the cell is in physical contact with the particle it wants to engulf.
2.A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. ... The cause is called the independent variable; and the effect is called the dependent variable.
Independent and Dependent Variable Examples. In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. You want to compare brands of paper towels, to see which holds the most liquid.
3.A negative control is a control group in an experiment that uses a treatment that isn't expected to produce results. A positive control is a control group in an experiment that uses a treatment that is known to produce results.
A negative control is part of a well-designed scientific experiment. The negative control group is a group in which no response is expected. It is the opposite of the positive control, in which a known response is expected.
These two controls, when both are successful, are usually sufficient to eliminate most potential confounding variables: it means that the experiment produces a negative result when a negative result is expected, and a positive result when a positive result is expected.
4.Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.Microscopes are used to produce magnified images. ... light microscopes are used to study living cells and for regular use when relatively low magnification and resolution is enough. electron microscopes provide higher magnifications and higher resolution images but cannot be used to view living cells.
Fluorescence microscopy is used
Answer:
Geographical isolation
Explanation:
The evolutionary mechanism that can probably explain the difference, in this case, is geographical isolation.
Geographical isolation represents one of the reproductive isolation mechanisms - an array of physiological and behavioural processes that leads to speciation in living organisms.
Geographical isolation refers to the separation of organisms of the same species in terms of physical geographical features such as distance, mountains, water bodies, etc. The separation causes each group to take different adaptive paths, eventually leading to speciation, that is, they become separate species.
In this case, the small population of monkeys in the isolated forest must have been geographically isolated from their counterparts in some ways back. They took a different adaptive path from the larger group as a result of geographical difference and eventually became a new species.
Answer:
False

Answer:
Water initially moves into the root hair cells by osmosis, because the mineral content of the cells is higher than that of the surrounding environment. Thus, a root pressure is established and extends into the microscopic tubes of the xylem.
