If a bacterium cannot use citrate agar will not change its color (stays green). On the other hand, if bacteria have the ability to use citrate, the medium will change its color from green to blue.
This happens because citrate agar contains pH indicator such as bromothymol blue which transforms from green to blue in alkaline conditions.
Answer:
The answer is "Option e".
Explanation:
please find the complete question in the attached file.
Its long tail disregards its short tail. Let's assume that even a short neck is a as well as a tail over, which claim, though, the short tails were mixed, shorter, and longer tailed mousses are created. It may also presume that the short mouse parental is always Aa. And we get AA, Aa, Aa, Aa, and Aa situations once their matter and they fall pregnant to both high and short tail mice but we wouldn't get the fat tail mouse unless the tail-mouse were as AA.
we always get two types of lines. It demonstrates there was no uniform AA genera. It is a case of the heterozygous dangerous gene, that can cause a set of identical alleles inside an organism to always be lethal.
Answer:
Anthropoids lived for approximately 0.86% of the total time.
Explanation:
- Anthropoids are the higher developed organisms that includes apes and ape mans.
- The age of earth is 3500 million and anthropoids lived for about 30 million years.
- By the simple calculations we can find out the data in percent which gives us the result nearest to 0.86%.
- That means 0.86% of 3.5 billion year is equivalent to 30 million years (time that was lived by anthropoids).
