How does phosphorus reach surface waters​

Biology
1 answer:
egoroff_w [7]3 years ago
5 0

It is an essential element for plant life, but when there is too much of it in water, it can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes. Soil erosion is a major contributor of phosphorus to streams.

Where is the protein on a DNA?​
QveST [7]

Answer:

Explanation:

The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father
prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.

Relate the analogy of “tug of war” to a water molecule.
ipn [44]

Answer:

water molecules undergo the 'tug of war' via the cohesion-adhesion theory

Explanation:

In plants specifically, a transpiration stream is formed via osmosis from roots into xylem and travels by the apoplast pathway to the leaves, where the water then evaporates from stomata into the surrounding air along the diffusion gradient. the water loss from the mesophyll cells lowers their water potential therefore water moves in via osmosis by both apoplast and symplast pathway from adjacent cells. water bonded to water= cohesion, water bonded to carbohydrates of xylem walls= adhesion. water is drawn up in tug of war-esc fashion against gravity to replace water evaporated, resulting in cohesion-adhesion theory.
