Answer:
1 black : 1 orange
Explanation:
This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.
In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.
This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.

A single-celled prokaryotic organism that is generally free-living and of few micrometers in length is bacteria. They are very small in size that cannot be seen without a microscope.
bacteria will be present in 100 milliliters of water.
<h3>How to calculate the number of bacteria?</h3>
Given,
- 1 milliliter = 1,500,000 bacteria
- 100 milliliter = ?
![\begin{aligned}\rm Bacteria &=\dfrac{ 100 \rm milliliter \times 1,500,000} { 1 \;\rm milliliter} \\\\&= 1,50,000,000 \;\rm bacteria \\\\&= 1.5 \times 10 ^{8} \;\rm bacteria\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Crm%20Bacteria%20%26%3D%5Cdfrac%7B%20100%20%5Crm%20milliliter%20%20%5Ctimes%20%201%2C500%2C000%7D%20%7B%201%20%5C%3B%5Crm%20milliliter%7D%20%5C%5C%5C%5C%26%3D%201%2C50%2C000%2C000%20%5C%3B%5Crm%20bacteria%20%5C%5C%5C%5C%26%3D%201.5%20%5Ctimes%20%2010%20%5E%7B8%7D%20%5C%3B%5Crm%20bacteria%5Cend%7Baligned%7D)
