Well, if pepsin reacts (breaks down) proteins then we must ask: is glucose a protein? No, it's not, it's a carbohydrate. so it would most likelt not react with glucose.
Meiosis<span> is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.</span>
Answer:
1. heterozygous yellow and star
2. 37
3. 1/8
4. 168
5. 1/4
Explanation:
Given ,
In f1 generation a cross is made between a true breeding black star bellied sneetch mated with a true breeding yellow starless sneetch
yySS x YYss
It is taken as - Y (yellow) is dominant over y (black)
and S (star) is dominant over s (starless)
1. F1 Generation
Genotype of parents yySS X YYss
gametes - yS, yS, Ys, Ys
All 16 offspring will have genotype YySs
phenotype would be heterozygous yellow and star
2. F2 generation cross
YySs X YySs
YS Ys yS ys
YS YYSS YYSs YySS YySy
Ys YYSs YYss YySs Yyss
yS YySS YySs yySS yySs
ys YySs Yyss yySs yyss
Genotype of offspring are –
YYSS – 1
YYSs – 2
YySS – 2
YySs – 4
YYss- 1
Yyss- 2
yySS – 1
yySs- 1
yyss- 1
2. Out of 16, 2 are black star bellied sneetches . Which means only 1/8 are black star bellied sneetches
So out of 300, 37 are black star bellied sneetches
3. Only 2 out of 16 are true breeding. i.e 1/8
4. 9 out of 16 are yellow star bellied sneetches, so out of 300, 168 are yellow star bellied sneetches
5. 4 out of 16 are true breeding yellow. Thus, ¼ are true breeding
Answer: Option 3
Explanation: Sound waves cannot travel in space because space is a vacuum, and sound waves require a medium to travel.
Furthermore, sound waves belong to the class of waves called MECHANICAL WAVES: as they require a material medium for their propagation
Options 1, 2 and 4 are inaccurate
The answer is Atlantic Ocean ; Pacific Ocean.
A continental divide is a divide that separates continent’s watersheds. A continent may have more than two watersheds. For example North America has five continental divides. But United States is divided into two very large watersheds, one which drains into the Atlantic Ocean and the other into the Pacific Ocean.
