Answer:
B. Traditional view
Explanation:
the traditional view is that nothing positive results from a conflict
The correct answer is: D. The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.
Hypotonic solution can be described as solution that has less solute and more water (H2O) than another solution. In order to maintain homeostasis, the water will move (via osmosis) into the cell, through the semipermeable membrane of the red blood cell.
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:
a. Light and carbon reactions occur in separate cells.
b. ATP is used to move a three-carbon ferry molecule from bundle-sheath cells back to mesophyll cells.
c. They require less water to live.
g. These plants function better in the hot, sunny environments.
Explanation:
The plants which carry out C₄ pathway or Hatch and Slack pathway are called C₄ plants. Examples are maize, sugar cane, sorghum. They live in hot, dry or arid habitats. C₄ plants have dimorphic chloroplast. The chloroplast is in bundle sheath cells does not have grana and in the spongy mesophyll cells have chloroplasts with grana. So, light and carbon reactions occur in separate cells. C4 plants are more efficient in photosynthesis than the C₃ plants. There is no photorespiration in C₄ plants as Phospshoenol pyruvate (PEP) carboxylase enzyme.
