Answer;

d. allows a geologist to predict what minerals will be found in a given igneous rock.

Explanation;

-Bowen's reaction series was deduced through laboratory procedures that cooled molten rock; the crystal formation in the igneous rocks produced always followed the same order.

-Bowen's Reaction Series is a proposed sequence of mineral crystallization from basaltic magma, based on experimental evidence. it is a schematic description of the order in which minerals form during the cooling and solidification of magma and of the way the newly formed minerals react with the remaining magma to form yet another series of minerals.

What are the possible blood types among the children of parents that are IAIB and ii? A. types A and B B. types A, B, and AB C.

balandron [24]

Answer:

The correct answer would be A. types A and B.

In ABO blood group, blood group is determined by three alleles $I^{A},$ $I^{B},$ and $i$ .

$I^{A}$ and $I^{B}$ are codominant to each other whereas $i$ is recessive to the other two.

The genotype of one parent is $I^{A}I^{B}$ . So, two types of gametes would be produced $I^{A}$ and $I^{B}$

The genotype of second parent is $ii$ . So, the gamete produced would be $i$ .

The cross would result in the production of offspring with genotype $I^{A}i$ and $I^{B}i$ .

Thus, the phenotype of the offspring would be blood group A and B.

How do beach nourishment and vegetation management differ in the ways they manage beach erosion?

kupik [55]

Answer:

Beach norishment refers to addition of sand on beach to reduce the erosion effect by water currents.

Vegetation management is the (re)plantation of plants to reduce the erosion effect on beaches caused by waves.

Explanation:

In the statements given above, addition of hard structure doesn't primarily means beach nourishment, likewise, vegetation management doesn't replace the sand on beach rather prevent sand erosion. However, vegetation management brings in plants that hold the sand especially on sand dunes. Floods cannot be totally controlled by beach nourishment but with the help of plants, their impact can be minimized.
