To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.

iogann1982 [59]

Answer:

The correct answers are option A. "Corals are animals".  B. "Corals are benthic organisms"., and E. "Corals live in tropical water".

The subclass of benthic organisms that corals belong is called Macrobenthos, for being large enough to be seen at the naked eye. Corals live mostly in tropical waters, because they do not tolerate waters with a temperature below 18 Celsius.

In the F2 generation of a dihybrid cross two phenotypes appear in the ratio 1:1. two phenotypes appear in the ratio 3:1. four ph
Bezzdna [24]

Answer:

four phenotypes appear in the ratio 9:3:3:1

Explanation:

<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>

The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.
