Incomplete dominance refers to a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the independent variable is the amount of noise.
Explanation:
During an investigation, the independent variable may be subject to change, in order to observe the effect it will have on the dependent variable.
In the case presented, the amount of noise to which employees are exposed represents the independent variable, which is modified by the use of headphones that block all or part of the noise.
The productivity —expressed in the number of shirts made— can be expected to be higher for employees not exposed to noise.
Other options do not apply because:
- <u><em>The number of shirts made by the employee</em></u><em>. Dependent variable
.</em>
- <u><em>The type of music the employees listen to while they work or the amount of training employees need</em></u><em>. These are not the variables studied.</em>
With the actions of the humans the biodiversity is facing a huge problem in most of the world, the habitats are destroyed, forests are cleared, animals are killed, water and air are polluted...
In order to conserve the biodiversity there are certain things that have to be put in action. The methods for conservation can be in-situ methods and ex-situ methods.
The in-situ methods are the preferred ones, as these methods are focused on conserving the environment as it is. This basically means that the ares that have larger biodiversity, and especially where there's species that are rare, should be made national parks, sanctuaries, monuments of nature, thus being protected by law.
The ex-situ methods are the ones that involve the conservation of the species outside of their natural habitat. That is done with gene banks, sperm and ova banks, seed banks, zoos and botanical gardens, collections of In vitro plant tissue and microbal culture, and captive breeding of animals and artificial propagation of plants.
