True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.

A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.

The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is  MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Integral membrane proteins are anchored in lipid bilayers. which of the
dolphi86 [110]

An integral membrane protein is a kind of membrane protein, which is perpetually combined with the biological membrane. All transmembrane proteins are integral membrane proteins, but not all integral membrane protein are transmembrane proteins.

These proteins are anchored in the lipid bilayers and only non-polar, hydrophobic amino acid residues would be found in the part of the protein, which crosses the membrane. In the interior of the bilayer, these residues would be hidden from the water solvent and associate with the non-polar lipid tails.

Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings
shtirl [24]

Answer:

The correct answer would be - 25%.

Explanation:

It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.

BbTt is a heterozygous condition and a cross with itself will produce :

Gametes: BT Bt bT and bt

          BT       Bt       bT       bt

BT     BBTT   BBTt   BbTT   BbTt

Bt      BBTt    BBtt    BbTt   Bbtt

bT     BbTT   BbTt    bbTT   bbTt

bt      BbTt     Bbtt    bbTt     bbtt

Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%
