When H. pylori was first discovered, researchers doubted the finding. It was thought that the acidic environment of the stomach was too hostile for microbes to thrive. Newer research using genetic analysis and culture techniques has revealed that there is a diverse gastric microbiota. Of the options below, what is the only one that does not involve genetic analyses?
A. Sequencing approaches have shown that the normal microbiota includes Archaea and provide mechanisms for studying their distribution.
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
C. Knowledge of the microbiota from sequencing efforts has been used to improve cultivation techniques.
D. Genetic analyses have been used to examine the dominant species in different individuals, showing that it varies from one individual to another.
Answers
Answer:
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
Explanation:
Genetic analyzes are tests that try to identify the genetic composition of a living being, being able to analyze the DNA in a profound way and obtaining crucial information about the organism. The most common way to carry out a genetic analysis is through the sequencing of genes, since they are segments of DNA molecules. Therefore, we can conclude that among all the response options presented above, all that refer to the sequencing of genes should be discarded. Thus, we can see that option B is the correct option, since the analysis of growth rates does not involve a genetic analysis.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answers
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

• How does precipitation affect the topology of the earth?
Answers
Answer: Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment. As moist air is forced up the windward slope it expands and cools, eventually causing water droplets to condense when the air is saturated. These droplets form clouds and grow to produce rain or snow that typically falls out on the windward side of the range. ... As air approaches the topography, it slows down.
Explanation:
Precipitation affects the topology of the earth positively and negatively ( excess precipitation leads to soil erosion while moderate precipitation repairs broken/dry soil surfaces making it fertile )
Precipitation has a positive and negative effect on the topology of the earth because excessive precipitation like heavy rainfall causes flooding and the heavy movement of flood water, washes away the surface soil ( erosion ) which affects the topology of the earth negatively. while
Moderate precipitation repairs dry and broken soil surfaces making the topology of the earth fertile, supporting the growth of plants and inhabitation of animals .
Hence we can conclude that precipitation affects the topology of the earth positively and negatively.

write the compliment triplets for the DNA sequence in each box in the following “ATG, ATC, GCA, AGT, AGC, GCC, GAT, AAG, TTG, CAG, TAG
Answers
Answer:
The complementary DNA sequence of each triplet is as follows:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC
Explanation:
A double-stranded DNA molecule is made up of two strands of DNA whose sequence are complementary to one another and linked by hydrogen bonds. According to the complementary base pairing rule as postulated by Chargaff, Adenine base will always hydrogen pair with Thymine base while Guanine base will always hydrogen pair with Cytosine base i.e. A-T, G-C
Based on the above explanation, the following triplets of DNA will have the following complementary sequences:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC

Bacterial DNA is a double-stranded helix that has to ___________ its strands during replication. The _______ of DNA strands at the replication fork creates twists farther down the helix that need to be ______ by DNA _______. Ciprofloxacin ______ this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Answers
Answer:
Bacterial DNA is a double-stranded helix that has to separate its strands during replication. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed by DNA gyrase. Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Explanation:
DNA which stands for deoxyribonucleic acid is the molecules that stores genetic information in most living organisms. For successive reproduction to take place as well as growth to occurs in organisms, the genetic information stored in the DNA must be copied into new cells. This is achieved through the process of DNA replication.
DNA is a double-stranded molecule that is helical in shape. For replication to occur, the double strands has to be separated so that the information stored within can be accessed and then copied. DNA helicases are enzymes which are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed otherwise, the DNA strands will break. The enzyme responsible for relaxation these twists is known as DNA gyrase. Thus, any drug like Ciprofloxacin than inhibits DNA gyrase will block the DNA replication process in bacteria thereby stopping the growth of the bacteria.
Bacterial DNA is a double-stranded helix that has to separate its strands
during replication. The unwinding of DNA strands at the replication fork
creates twists farther down the helix that need to be relaxed by DNA gyrase.
Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the

The antibiotic referred to as Ciprofloxacin acts on the DNA of the bacteria
and it does this by inhibiting the enzyme that is required for DNA
synthesis. This stops replication and the anthrax bacteria from growing and
forming new organisms.
