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.
Stroma, in a biological explanation, the fluid in between grana, where carbohydrate formation reactions occur in the chloroplast of plant cells photosynthesizing.
Explanation:
Part A
In the bright daylight, the Calvin cycle happens indoors in the stroma. throughout the Calvin cycle, the results ATP and NADPH are conventional convert molecules of carbonic acid gas into high-energy sugars.
Part B
In the darkness, the Calvin cycle conjointly occurs within the stroma. through the Calvin cycle, the products ATP and NADPH are used to change molecules of CO2 into high-energy sugars.
Part C
There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be sustained.
Translation occurs in the nucleus to produce a pre-mRNA molecule. The pre-mRNA is the processed into the mature mRNA which exists the nucleus and is translated into the cytoplasm.
So, the answer is B) NUCLEUS
Answer:
Option C. The lungs.
Explanation:
Alveolis are the air sacs in the lungs which main function is to get oxygen into your bloodstream and carbon dioxide leaves the blood.
The alveolis are located in the lungs, and it's where the respiratory and circulatory systems meet, for the reasons stated before.
Therefore, the correct option is Option C.
Whildlife centers are made to preserve the lion population.
