Answer:
Biology is the study of Living organisms whereby they are clustered into distribution , origin , behavior , anatomy their physiology and morphology.
Biology as a subject has changed my views and conspiracies about the existence of organisms in their ecosystem .Its like from biology you get to know the meaning of life in details right from the origin to death of the organism .
As a human being I have realized much on how biology helps even beyond the class , since I have learnt the reason why each organism belongs to a certain habitat and specific niche of the ecosystem , I have learnt to respect and conserve such organisms as they deserve to exist in that habitat , and their is an interdependency whether direct or indirect .
Also with the knowledge I have acquired on anatomy and the physiology of organisms , I can do a first aid to an individual who has suffered outdoor pass outs or injuries to reduce the impact of the situation before he or she reaches the hospital .
I believe biology has impacted a very important part of my life and I look forward to take further studies in this field to broaden my knowledge even more .
The right answer is A) Trisomy
Aberrant karyotypes containing an abnormal number of chromosomes are known in the human species. The best-known (and most common) chromosomal abnormality is trisomy 21, which is responsible for Down syndrome (mongolism). There are others such as Turner syndrome (woman with a single X chromosome) or Klinefelter syndrome (man XXY).
These abnormalities originate from the non-disjunction of the chromosomes of a pair of homologues during metaphase I of meiosis. At the end of division I, a daughter cell contains the two chromosomes of the pair considered and the other cell does not contain a chromosome of this pair. A similar result can be obtained during a bad distribution of chromatids during anaphase II.
After fertilization from a gamete of this type, a trisomy or a monosomy is obtained.
Answer:
Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products.
Explanation:
Hope this helps!
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. ... Breaking chemical bonds absorb energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
