nisms? Green olives may be preserved in brine, which is a 20-30% salt solution. How does this method prevent contamination by microorganisms? High salt concentrations raise the ph, thus inhibiting the process of glycolysis. Bacteria can't survive in a hypertonic solution because they lose water. High salt concentrations lower the ph, thus inhibiting the process of glycolysis. Bacterial cell walls are shriveled up by salt, causing the cell to burst.

The correct answer is Bacteria can't survive in a hypertonic solution because they lose water.

The 20-30% salt solution is hypertonic as Compared to the bacterial concentration of salt. In this case, the bacteria present in the solution would lose water. Due to excess loss of water, the bacteria would eventually shrink and die. Hence, green olives preserved in the brine would be safe from microbial attack.

Answer:

Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces by simply replicating its chromosome and dividing into two daughter cells. The daughter cells that result from this division are genetically identical to each other and to the original parent cell. Thus, over time, asexual reproduction in bacteria can lead to a population of hundreds of thousands of cells, all of which are genetically identical to a lone original parent cell.

Given their asexual method of reproduction, it is tempting to think that bacteria are sorely lacking in genetic variation, but this is not the case. Prokaryotic cells have developed a number of methods for recombining their genetic material, which, in turn, contributes to their genetic diversity. The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. However, not all types of bacterial cells are capable of engaging in all three processes.

Alchen [17]

The answer is a. mesosphere

Earth’s atmosphere is divided into 5 layer, from the outer layer it will be: Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere. The coldest area of the atmosphere would be the middle layer called mesosphere. The average temperature of this atmosphere is −85 °C , a bit lower than stratosphere temperature −60 °C.

Which term describes the example below?A child with no freckles has a mother who has freckles and is heterozygous and a father w
Natali5045456 [20]
It is C as to have freckles you have to have a dominant and recessive gene (can be worked out using a punnett square) as the child has 50% of not having freckles like his dad or 50% having freckles like his mom. 
                     male genes(homozygous recessive)
                     f            f

female    F    Ff           Ff
genes
              f     ff             ff

so ff is not having freckles and being homozygous recessive, or Ff having freckles and being heterozygous.

So the child is heterozygous  so C
