Explanation:
The correct pairing of the homologous chromosomes and their correct segregation (a chromosome for each daughter cell) are key to the proper development of the new cells, and specially of the new individual if we are talking about the early stages of embryogenesis. If there is an error during the splitting of chromosomes, and one cell gets a double set and the other misses a chromosome, numerical chromosomal abnormalities occur. These numerical abnormalities can happen on autosomes or sexual chromosomes, and common examples are as Down Syndrome (trisomy 21), Patau Syndrome (trisomy 13), Turner Syndrome (45,X) and others.
The number of the trisomy indicates the chromosome pair that suffered the adding or the subtraction of its chromosome.
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10 thousand years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems and as "the total of arrangements, activities, and inputs that people undertake in a certain land type. Land use is one of the most important drivers of global environmental change.
Answer:
The correct answer is : Hormones in the plant help fruits develop and ripen.
Explanation:
- Development of fruits and its ripening is brought about by a number of plant hormones :
- Auxin - It promotes the cellular growth, both with respect to cell-division and cell elongation. It promotes the cells in the fruit to expand isodiametrically.
- Gibberellic Acid - This hormone delays the ripening of fruits and also prevents senescence. It helps the fruits to acquire enhanced characteristics.
- Cytokinin - Promotes cell division during the development of fruit.
- Ehylene - Promotes the ripening of fruits.
Answer:
Psychology is the academic discipline concerned with the inner life (knowing, feeling and striving) and the behavior of people. It generally does this by following the scientific method, but in some cases it makes use of symbolic interpretation and critical analysis, following the example of other social sciences.
The goal of psychology is to acquire knowledge about the behavior of humans, both in their everyday environment and under special circumstances. With the emergence of the behavioral movement, the object of psychology was reduced to the outwardly observable and measurable behavior of animals humans, because the inner life would not be objectively registered by scientific observation, but only subjectively by introspection and understanding. This limitation has been reversed, among other things by the 'cognitive revolution' in psychology, by the great social importance of psychotherapy and by the connotations that the word 'psychology' evokes in everyday language use.
