when placed in the same container, oil and water do not mix because
Oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.
What are the characteristics of water?The characteristics of water are as follows:
It is a universal solvent that is polar in nature. It possesses high heat capacity and heat of vaporization. It has properties like cohesion and adhesion. The solid form of water is less dense as compared to its liquid form.Due to differences in their polarity, the molecules of water and oil are not intermingled with each other. Due to this, the polar compounds are dissolved in a polar solvent while non-polar compounds like oil are dissolved in a non-polar solvent. Thus, the molecules of oil will finally stick to each other and are immiscible with water.
Therefore, oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.

What are the types of neuron ?Neurons basic microscopic unit of nervous system which is responsible for carrying information to different parts of the body by using electrical and chemical signals and coordinate all of the necessary functions of life.
It has three parts such as Soma or cell body which receives information and contain the cell’s nucleus, Dendrites a thin filament which carry the information from other neurons to the soma, Axon is a long projection that carries information from the soma and sends it to other cells.
Neurons involve in impulse transmission can be presynaptic neuron which emits the nerve impulse and the postsynaptic neuron receives this impulse.
Neurons can be Sensory neurons which carry the information from the sensory organs like skin, eyes, ears, nose and Motor neurons, Interneurons form a bridge between two neurons.

In a population of frogs, there is a dominant allele H that improves the survival of eggs in moderately dry conditions compared to the wild-type and recessive h allele. Imagine that climate change causes the environment where these frogs live to become more dry. Individuals with the drought-resistant eggs on average have 21 viable offspring per frog per generation, whereas those without that phenotype on average have only 12. If we start off with genotype frequencies of .02 HH, .03 Hh, and .95 hh, what is the average excess fitness of the H allele?
Answer:
8.55
Explanation:
I n the year1908, these two men Godfrey Hardy and Wilhelm Weinberg gave a specification of the relationship between the frequency of genotype and frequencies of allele that should occur when such a population is in equilibrium
p²+2pq+q² = 1
we have,
p² = 0.02
p = √0.02
such that frequency of H is = 0.1414
2pq = 0.03
q² = 0.95
q= √0.95
such that frequency of h =0.9746
(21-12) * 0.95 =
8.55 frogs per generation
H and h will coexist.
You have an Elodea sprig in a test tube containing bromothymol blue. Then you watch it for several days. At what time of day will the oxygen level in the tube be the lowest?
a)just before sunset
b)midnight
c)just before sunrise
d)mid-afternoon
Answer:
c
Explanation:
If you put an Elodea plant in a test tube containing bromothymol blue and watch the oxygen level, the time of the day in which the oxygen level in the tube would be lowest will be just before sunrise.
First, there is a need to understand oxygen is produced as a result of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
The process of photosynthesis takes place in 2 reactions:
Light-dependentLight-independentOxygen is produced from the splitting of water in the light-dependent reaction. Hence, the production of oxygen stops when there is no light - when the sun sets.
Whatever quantity of oxygen that has been produced just before the sun sets would remain and will gradually be used for respiration by the Elodea plant until the sun rises again the following day.
Thus, the level of oxygen in the tube would usually be lowest just before the sun rises and oxygen can be produced again.

describe the process of building a paradigm and of shifting one
Answer:
Explanation:
A paradigm shift is a major change in the concepts and practices of how something works or is accomplished.
A paradigm shift very often happens when new technology is introduced that radically alters the production process of a good or service.
Although the idea of paradigms has been around for quite some time, the concept was explored by physicist and philosopher Thomas Kahn Kuhn.
What happens when self-determination mechanisms break down?
Answer:
When self-determination mechanisms break down it mistakes self-tissue as foreign agents and pathogens. This results is Auto-Immune disease.
HOPE THIS HELPS!
When the self-determination mechanisms break down, the body misinterprets its own tissues as foreign antigens, which activates the autoimmune mechanisms to destroy the body's own cells, mistaking them for foreign factors, this happens mainly in mantle autoimmune diseases.
Autoimmune diseases are a group of diseases in which tissue damage is caused by a humoral or cell-mediated immune response to a person's own antigens.
What are antigens ?In immunology, an antigen (Ag) is a molecule or molecular structure or any foreign particle or pollen grain that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body can trigger an immune response. The term antigen originally referred to a substance that is a generator of antibodies. Antigens can be proteins, peptides (chains of amino acids), polysaccharides (chains of monosaccharides/simple sugars), lipids or nucleic acids. Antigens are recognized by antigen receptors, including antibodies and T-cell receptors.
