Answer:
The correct answer is A.They secrete enzymes that break down dead matter or living organisms and absorb the released nutrients.
Explanation:
Most of the fungi are saprophytic which means they grow on dead and decaying organic matter like fallen trees, leaves, and dead animals and get nutrition by digesting these dead organic matter.
Fungi do not have stomach so they secrete enzymes like α- amylase, cellulase, xylanase, etc from their hyphae that helps in digesting complex organic molecules into simple form which can easily be absorbed by these fungus.
By decomposing these organic matter they recycle the nutrients and clean the pollution from the environment. So the correct answer is A.
Answer:
1/8
Explanation:
Father: normal vision, type A
Mother: normal vision, type A
They can only produce a colourblind son if female is the carrier for it:
XC Xc
XC XCXC XCXc
Y XCY XcY
XcY son will be colorblind. Hence father has XCY genotype and mother has XCXc genotype for vision.
They can only produce type O son if both of them are heterozygous for type A:
A O
A AA AO
O AO OO
OO son will have type O blood. Hence both father and mother have AO genotype for blood type.
Probability of having a female child=1/2
Probability of having a normal vision female child = 1 since in the first punnett square it has been shown that all female children have normal vision ( half are carriers )
Probability of having type O child = 1/4
Probability of having a female child with normal vision and type O blood = 1/2 * 1 * 1/4 = 1/8
