Answer: 3. Area of upwelling

Explanation: Wind blowing across the ocean surface push water away. So, water rises up from beneath the surface to replace the water which was pushed away. This process is called "upwelling". Waters that rises to the surface as a result of upwelling is typically colder and very rich in nutrients. These nutrients "fertilize" surface waters and so, these waters often have high biological productivity for fish to feed on.

Answer 4: Human activity

Explanation: The largest source of ocean pollution comes directly from land sources, such as oil, land, septic tanks, farms, ranches, motor vehicles, among others. Thousands of tons of waste and garbage are dumped into our oceans every day.

Answer 5: abrasives and polishes

Explanation: diatomaceous earth (Diatomaceous earth is the fossil remains of diatoms) has applications, among which can find: mild abrasive in hygiene products such as toothpaste or facial scrubs, liquid absorbent, porous support for chemical catalysts, anti-caking agent, dynamite stabilizer, thermal insulator.

In a flowering plant, blue flower (B) trait is dominant to white flower (b) trait. A true-breeding blue flower plant (BB) is cro

scoundrel [369]

Answer: D. 100%

Explanation:

One parent is with is a true breeding blue flowering plants this means the two alleles of the genotype are homozygous dominant alleles (BB).

The other parent is a true breeding with flowering plant, this means the two alleles of the genotype are homozygous recessive alleles (BB).

When both parents are crossed, the possible genotype outcome is

B B * b b

Bb Bb Bb Bb

Therefore since the blue flowering plant allele (B) is dominant to the white flowering plant allele (b) the probability of an offspring outcome to be a blue flowering plant is 4/4 which is 100%.44

Answer is 100%

How does archbishop usshers work compare to that of james hutton

Nataly_w [17]

James Ussher was a creative scholar, a church leader and became famous for his genuine letters of the church. He is the Archbishop of all Ireland and majorly impacted Reformation theology. He is best known for his chronology research that concluded Adam was created in 4004 B.C. In reality, Ussher was a first-class scholar very involved in scholarly research. He regularly interacted with “the most learned men of the day” to intellectually savor their ideas. He was also “a real connoisseur of books,” and there was scarcely a book in any British library that he was unfamiliar with. While James Hutton is known as the Father of Modern Geology, Hutton is a Scottish Geologist and a naturalist who originated the concept of earth’s crust during geological history, which explains the features of the Earth's crust by means of natural processes over geologic time. Hutton had formulated controversial theories of the origin of the earth and of atmospheric changes known as 'uniformitarian’s'. This paved the way for modern geological science.
