This process is called Denitrification. The process is undertaken by the denitrifying bacteria, whose action is converting nitrates in the soil to free atmospheric nitrogen and therefore, depleting soil fertility and reducing agricultural productivity. Examples of denitrifying bacteria are thiobacillus denitrificans, micrococcus denitrificans among others.
Answer:
A) tortoiseshell female; black male
Explanation:
Females have two X chromosomes and males have an X and a Y chromosome.
<u>The possible genotypes and phenotypes are</u>:
- XᵒXᵒ: black female
- XᵒY: black male
- XᴼXᴼ: orange female
- XᴼY: orange male
- XᵒXᴼ: tortoiseshell female
<u>Cross of a black female and an orange male</u>
<h3>XᵒXᵒ x XᴼY</h3>
The female only produces Xᵒ gametes. The male produces Xᴼ and Y.
The possible offspring therefore is: XᵒXᴼ (tortoiseshell females) and XᵒY (black males). The answer is A.
False because extrusive rocks have fine-grained texture due to the rapid cooling of magna above the earth surface. On the other hand extrusive rocks have course grained texture due to slow cooling of magna beneath the Earth's surface
