The bacteria that you would not use a Gram stain on are Escherichia coli, Pseudomonas spp. and Clostridium spp, and Neisseria meningitidis.
<h3>
What are Gram stain negative bacteria?</h3>
Gram-negative bacteria have cell walls with thin layers of peptidoglycan and high lipid content.
This causes them to appear red to pink under a Gram stain.
<h3>Examples of Gram - negative bacteria</h3>
Gram-negative bacteria include:
- Pseudomonas,
- Klebsiella,
- Proteus,
- Salmonella,
- Providencia,
- Escherichia,
- Morganella,
- Aeromonas
- Citrobacter
- Neisseria meningitides
Thus, the bacteria that you would not use a Gram stain on are Escherichia coli, Pseudomonas spp. and Clostridium spp, and Neisseria meningitidis.

Answer:
Option D, Gene Flow
Explanation:
Gene flow is defined as the flow of genes from one population to other thereby causing variation in the base population. Here the population of mole will have a certain number of genes but its interaction with a foreign species will lead to evolution of population through natural selection and genes of this foreign species will also get mixed with genes of mole population which later on may lead to further variations with in a single set of population inclusive of all
.
Hence, option D is correct
Answer:
Two gametes end up with 30 chromosomes, one gamete will have 31 and one will have 29.
Explanation:
During meiosis, a single diploid cell divides into four haploid cells with half the chromosome number than the parent cell.
During meiosis I, homologous chromosomes separate and the chromosome number in the two daughter cells goes down by half. During meiosis II, the "sister" chromatids separate, and the chromosome number in the respective daughter cells remains the same.
Non-disjunction of a single dyad in meiosis II causes that one of the daughter cells will have an extra chromosome, and another will be lacking one. The two other gametes will be normal.
I drew a simple example of what would happen during meiosis of a 2n=4 cell if there was non-disjunction in a single dyad during meiosis II.
