Orchid seeds are tiny, with virtually no endosperm and with miniscule cotyledons. If such seeds are deposited in a dark, moist e

Xelga [282]

<h2>c.is the correct option</h2>

Explanation:

Fungi might assist in seed germination by providing the embryos with some of the organic nutrients the fungi have absorbed

Fungi is an eukaryote which digests food externally and absorbs nutrients directly through its cell walls
Fungi absorb nutrients through following three ways:
By decomposing dead organic matter: obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds
By feeding on living hosts:fungi live in or on other organisms and get their nutrients from their host
Living mutualistically with other organisms: mutualistic fungi live harmlessly with other living organisms;fungal component absorb water and minerals and provide them to algal component which uses them to make food

In dark,moist environment nutrient availability is less hence fungi helps in providing orchid seeds the nutrients which it has absorbed

jeyben [28]

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is

1. What is Jane's genotype?

2. What is Paul’s genotype?

3. Where did Jane get her gene for curly hair? From her mother or father?

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?

6. What fraction of their children would have straight hair and no dimples?

7. What fraction should have dimples but not curly hair?

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was Aa)

4. False. She was having straight hair

5. Offspring of Paul and Jane

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5

Mutagens such as pollutants and UV light can cause mutations in DNA to occur at a higher rate than normal. These mutations may b

Alecsey [184]

Correct answer: D). They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.

Cancer is uncontrolled growth of the cell in the body. The Old cell does not die and instead of that, they have grown out of control, which results in the formation of new abnormal cells. These may form a mass of tissue called a tumor.

Due to uncontrolled growth of a cell, the normal function of neighboring tissue or organ may be disturbed or it might damage vital organ such as kidney, heart, lung etc and may cause death.
