C. according to Earth's existing magnetic field.
Answer;
Tuberculosis
Explanation;
Bloodborne transmission involves transmission through contact with infected human blood and other body fluids such as semen, viginal secretions etc.
These pathogens include; HBV, HIV, STD's and viral hemorrhagic fevers.
Tuberculosis (TB) is not transmitted through the blooborne method but through airborne particles.
The "scissors" of the molecular biology are: DNA Restriction enzymes.
A restriction enzyme is a protein capable of cleaving a DNA fragment at a characteristic nucleotide sequence called a restriction site. Each restriction enzyme thus recognizes a specific site. Several hundred restriction enzymes are currently known.
Naturally present in a large number of species of bacteria, these enzymes have become important tools in genetic engineering.
The "glue" of the molecular biology are: DNA ligase
In molecular biology, DNA ligases are ligase-class enzymes that catalyze the formation of a phosphodiester bond between two segments of DNA. DNA ligases are involved in several essential cellular processes of DNA metabolism: in DNA replication, suture of Okazaki fragments, and in DNA repair and homologous recombination.
The use of these tools in molecular biology: Cloning
Molecular cloning is one of the bases of genetic engineering. It consists of inserting a DNA fragment (called insert) in an appropriate vector such as a plasmid for example. The new plasmid thus created will then be introduced into a host cell, generally the Escherichia coli bacterium. This will then be selected and multiplied to obtain a large amount of the plasmid of interest. Cloning a gene involves inserting it into a plasmid. A clone will be the bacterial transformant that contains this particular plasmid. In this case we speak of clone because all the individuals of the bacterial colony are genetically identical. Molecular cloning is thus different from reproductive cloning (creating an individual genetically identical to another but of a different age) or therapeutic cloning (making tissues from stem cells to perform transplants compatible with the recipient).
Molecular cloning requires restriction enzymes capable of cleaving the DNA, and DNA ligase capable of re-gluing the DNA fragments. Ligase was isolated for the first time from T4 bacteriophage. This enzyme is involved in the repair and replication of DNA. It can bind DNA fragments with compatible sticky ends. At higher concentration, this enzyme is also able to bind two ends of DNA as shown here. T4 DNA ligase works using ATP and Mg ++. It has an activity optimum of 16 ° C, but remains active at room temperature.
Wind has no effect on a plants respiration rate True
Where sugars are formed are referred to as the sink True
Both the xylem and phloem do not use any plant energy to translocation materials True
The amount of humidity in the air will affect transpiration True
The rate of transpiration reduces as the relative humidity of the air around the plant increases. Compared to more saturated air, dryer air makes it simpler for water to evaporate. A plant's transpiration rate will rise when air movement around it increases.
<h3>What about plants respiration?</h3>
- Water vapor is lost via the process of transpiration through a plant's stomata.
- When it's very hot outside, the plant loses water vapor to cool down, and water from the stem and roots flows up or is "drawn" into the leaves.
- In addition, plant transpiration contributes significantly to the leaf's energy balance by providing evaporative cooling.
- Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration.
- Plants use transpiration for a variety of purposes.
- The direct effects of transpiration include controlling the plant's temperature and supplying water for photosynthesis.
- Additionally, it facilitates the movement of glucose and nutrients through the plant's vascular tissues.
- Plants lose water through a process known as transpiration.
- A plant's roots can collect up to 99.5% of the water that the plant transpires, which is not used for growth or metabolism.
- For the surroundings to remain wet, transpiration is necessary.

Answer:
_________
Explanation:
Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
