Answer:
1/8.
Explanation:
Karyotype may be defined as the visual appearance and the number of chromosome of the organism. Karyotype helps in studying the chromosomal abnormalites.
The human male has extra piece at chromosome 4. The abnormal pattern on the chromosome 7. The probability to inherit the defective chromosome 4 is 1/2, defective chromosome 7 is 1/2 and the probability of Y chromosome is 1/2. The probability of child to inherit all these chromosome is (1/2) × (1/2) × (1/2) = 1/8.
Thus, the answer is 1/8.
Answer:
The correct answer is a. domain Eukarya.
Explanation:
Bacteria archaea and eukarya are considered as the three domains of life. Bacteria and eukarya lack a membrane-bound nucleus and other membrane bound organelle therefore they are considered in prokaryotes and organisms having membrane-bound nucleus comes under domain eukarya.
So the organism which have eukaryotic cell comes under domain eukarya. These organisms can be single cellular or multicellular and their genetic material is packed in a double membranous structure called the nucleus. So the correct answer is a. Eukarya.

Answer:
A watershed is a region obtaining both land and water. This is a shallow land region which accumulates water from drainage obtain from different sources like lake, river and pond. A watershed may also develop in a forest ecosystem. The clear cutting of forest will result expose more amount of soil nutrients for erosion by water as compared to natural forest. Therefore, nutrient loss will be higher in clear- cut watershed than natural forest watershed.
A colorimetric method based on tetrazolium salts (e.g., MTT, XTT, CCK-8/WST-8) are especially useful for assaying the quantification of viable cells.
