<u>Answer</u>: Conduction
<u>Explanation</u>:
- There are basically 3 types of processes that occur for heat transfer - conduction, convection and radiation,
- <u>Conduction</u> is the process of heat transfer in which the objects are placed in a <em>direct contact</em> and the heat travels from one object to the other due to the temperature difference between them. It is a slow process and occurs usually when the heat transfer has to to take place between solid objects.
- <u>Convection</u> is the process of heat transfer in which energy transition takes place in the liquids and gases and the heat gets transferred due to the density difference between the fluids.
- <u>Radiation</u> is a type of heat transfer in which the heat is transferred without any sort of physical contact using electromagnetic waves.
Since, in the given question the <em>heat is being transferred through a direct contact, it is conduction which is taking place.</em>
Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
In arabidopsis, a mutation causing the b-class genes to be non-functional will result in the organ identity of the four whorls to be; Sepal, sepal, Carpel, carpel. Arabidopsis is an angiosperm, a dicot from the mustard family Brassicaceae. It is widely used as a model organism in plant biology. It offers important advantages for basic research in genetics and molecular biology.
The statement “One of the first steps in harnessing geothermal energy is to drill a well into a geothermal reservoir.” Is true. The answer is letter A. The energy in the Earth’s crust comes from the formation of the planet and radioactive decay of materials.
