Answer: B. Xylem

Explanation:

Xylem is a blood vessel that if found in plants. The xylem tissues helps in conduction of water and minerals from the roots to different parts of the plants just like blood vessels helps in transportation of bodily liquids like blood, lymph and others to all the body parts. The xylem tissues particularly includes xylem vessels, tracheids, fibers, and parenchyma.

Xylem vessels: They form a tube like cylindrical structure by the fact that the cells are joined together end to end.

Tracheids: They are long and narrow cells which help in upward conduction of water.

Xylem fibers: These cells die in maturity. These cells provide strength to the plants in maturity.

Xylem parenchyma: These cells are living. They also help in conduction of water. They store the metabolites.

Match each hazardous waste with its matching description.

Sphinxa [80]

Matching each hazardous waste with its description is shown below :

Hazardous waste description

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

Too much exposure to these hazardous waste always leave a negative effect on the health of individuals, Asbestos are used in the roofing of older buildings and can be found in older landfills. the fiber from asbestos affects the Lungs ( alveoli ) of humans which might lead to lung cancer.

Mercury are used for PC's backlight and also in the mother board of modern computers too much exposure to mercury can lead to brain damage.

Cadmium are hazardous cancer causing agent used in making industrial batteries, prolonged exposure to lead poses several health risk which includes reproductive issues because lead can cut across placenta barrier between a pregnant woman and unborn child.

Hence we can conclude that matching each waste to its description is as

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

For the following three cultures, using any resource find out if they are obligate aerobes, facultative anaerobe, or obligate an

Dima020 [189]

Answer:

Escherichia coli - Facultative anaerobe

Micrococcus luteus - Obligate aerobe

Clostridium sporogenes - Obligate anaerobe

Explanation:

In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are Mycobacterium tuberculosis and Micrococcus luteus.

Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the Escherichia coli.

Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are Clostridium sporogenes and Clostridium botulinum.

Tamiku [17]

Answer:

maybe?

Explanation:

Characteristics of Clostridium Tetani

Clostridium tetani is an obligately anaerobic bacillus that is gram positive in fresh cultures but may have variable staining in older cultures or tissue samples.25 The complete genome of the organism has been sequenced, and its products were recently compared with other clostridia.26 During growth, the bacilli possess abundant flagella and are sluggishly motile. Two toxins, tetanospasmin (commonly called tetanus toxin) and tetanolysin, are produced during this phase. Tetanospasmin is encoded on a plasmid that is present in all toxigenic strains.
