What are the drawbacks of VSEPR theory?
The VSEPR theory is simple yet powerful. Nevertheless, like any simplified model, it has its limitations. First, although it predicts that the bond angle in H2O is less than the tetrahedral angle, it does not make any attempt to predict the magnitude of the decrease. Second, the theory makes no predictions about the lengths of the bonds, which is another aspect of the shape of a molecule. Third, it ascribes the entire criterion of shape to electrostatic repulsions between bonding pairs, when in fact there are numerous contributions to the total energy of a molecule, and electrostatic effects are not necessarily the dominant ones. Fourth, the theory relies on some vague concepts, such as the difference in repelling effects of lone pairs and bonding pairs. There also are some species for which VSEPR theory fails. Nevertheless, despite these limitations and uncertainties, VSEPR theory is a useful rule of thumb and can be used with reasonable confidence for numerous species.l
What happens to an organism thats fails to maintain homeostasis?
If your body fails to maintain homeostasis it can result in disease or death.
Why is the steady state theory wrong?
The Steady State Hypothesis fails to explain the existence of the Cosmic Microwave Background Radiation; or to adequately explain the ratio of hydrogen to helium in all parts of our Universe. Big Bang Cosmology successfully explains the existence, isotropy, and spectrum of the CMBR, as well as the universal ratio of hydrogen to helium. In addition, if our Universe has been in an eternal steady state, then we would see 1) quasars at all distances from us. We don't; we only see them far away. 2) white dwarf stars older than 12 billion years. Again, we don't. 3) more abundant decay products of long-life isotopes. We don't; the ratios never show any age of such isotopes greater than about 10 billion years.

Explain the gap between theory and practice in colonial policy?
The gap between theory and practice in colonial policy arises from the disconnect between the lofty ideals and principles put forth by colonial powers, such as promoting civilization and modernization, and the harsh realities of implementing these policies on the ground. In practice, colonial policies often resulted in exploitation, oppression, and the erosion of indigenous cultures and societies, highlighting the contradictions between theory and the actual impact on colonized populations.
When can a theory be changed?
whenever an experiment fails to confirm the theory it is no longer a theory ... it becomes a hypothesis

is probably an incorrect theory

What is the difference between theory and a Doctrine?
A theory is an explanation or interpretation of a phenomenon supported by evidence and reasoning, whereas a doctrine is a set of beliefs or principles, often religious or political in nature, that are taught and followed as authoritative. Theories are subject to change and revision based on new evidence, while doctrines tend to be more fixed and dogmatic.
What statement fails to support the endosymbiotic theory?

How would you explain paper records?

inhuman ??????? but one fails to realize that if Japan had the Atomic bomb first, they would have used it inmass against the allies....... food for thought.
What causes a hypothesis to be rejected?
A hypothesis will be rejected if it fails the necessary testing required for it to become a scientific theory.
When tour brakes fails the first thing you should do?
Explain to us what are "tour brakes" -never heard of them.
How many test a theory must pass?
There is no upper limit. Any time it fails, its wrong and must be reformulated ... or discarded.
