Answer:
25% unaffected child with two normal gene.25% affected child with two recessive gene but 50% unaffected child but is a carrier
Explanation:
To have an autosomal recessive pattern you inherit two mutated gene one from each parent. It usually passed by two carriers. One recessive and other dominant.
Hello there!
These structures are called Vestigial Structures.
The Vestigial Structures are those whose original function was lost during evolution. In humans, these structures are the appendix, the coccyx, the wisdom teeth and others.
In animals, examples of vestigial structures are the wings of flightless birds, hind leg bones on whales and pythons and eyes in blind fishes. Those vestigial structures help scientists study the evolution of some species.
Answer:
A. exposure - use of artificial sweeteners
disease - bladder cancer
In this research artificial sweeteners are used as the exposure that leads to bladder cancer disease.
B. Bladder cancer No bladder cancer
Artificial sweeteners 1293(a) 855(b)
No artificial sweeteners 1707(c) 2145(d)
Total 3000 3000
Cases -
- Risk factor (Artificial sweeteners) present (1293)
- Risk factor (Artificial sweeteners) absent (1707)
Controls
- Risk factor (Artificial sweeteners) present (855)
- Risk factor (Artificial sweeteners) absent (2145)
Odds ratio or strength of association between exposure and disease
OR= Cases with exposure/cases without exposure= a/c divided by b/d
So, the putting value ad/bc= 1293*2145/855*1707
= 1.9
OR would be 1.9
C. this interprets that there is a 90% increase in the chance of bladder cancer if exposed to artificial sweeteners or people with bladder cancer have a 1.90 times higher odds of using artificial sweeteners compared to controls
Answer:
B. Lysosome
Explanation:
It contains digestive enzymes.
Bauplan is the assembly of the body structure which is common in the organisms belonging to the same phylum. The Same bauplan determines that a body part of the organisms are same and they will be in the same phylum in the Evolution also. Bauplan includes symmetry, segmentation, and limb disposition.
