Both klebsiella pneumoniae and streptococcus pneumoniae avoid phagocytosis by releasing a-b toxins that kill leukocytes.

Biology
1 answer:
Kobotan [32]3 years ago
7 0
This is a false statement.

Klebsiella pneumoniae and Streptococcus pneumoniae are two bacteria who are encapsulated, that means that they are surrounded by an envelope. This capsule is critical to their pathogenicity since it protects them from the phagocytes of the human immune system. Certain proteins located on the surface of their capsule prevent the phagocytic cell from adhering to the bacteria and engulfing it.

Which option denotes the professional that most likely will be called in to help in the following scenario?
rjkz [21]

The professional that most likely will be called in to help seismologist.

<h3><u>Explanation:</u></h3>

When an underwater earthquake has just been recorded in the middle of the Pacific Ocean, the seismologists will be called to determine if the effects of this earthquake and whether or not it will cause tsunamis off the coast of Hawaii.

Seismology is the study of earthquakes, the escalation of waves and the effects they might have. A seismologist is a scientist who is concerned with these studies. They make use of seismographs and other relevant tools to gather essential data which helps in reading the planetary movements and understanding them better. The study does not always predict an earthquake but it helps in predicting the possibility of tsunamis. Seismology enabled the development of tsunami warning systems.

Third-class lever systems, like most skeletal muscles, enable great strength but sacrifice speed and distance of movement. Third
mel-nik [20]

Answer:

The correct answer will be- false

Explanation:

The understanding of the biomechanics of the human movements is studied by the lever system which represents the rigid bar which comes on a fixed point as a result of the force exerted.

The lever systems are defined into three types into which the last lever system is the third lever system which is the recognized by the muscle (effort) in the middle of the joint (fulcrum) and the weight of the body (load).

These movements are related to the exercise like jumping, running and kicking which requires speed and distance to be covered. Thus, false is the correct answer.

the effort is the middle component and lies between the fulcrum and load.

What happens as a result of osmosis when an animal cell containing 1% sugar is placed in pure water
Mama L [17]

The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

If 1% sugar solution is placed in pure water, then there would be a higher concentration of water molecules outside the cell compared to inside the cell. The solution outside the cell would be hypo-tonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.

In ________ immunity, the body’s reaction to foreign substances is the same regardless of the pathogen, but in _________ immunit
jeka94

Answer:

Innate; adaptive

Explanation:

Immunity is the ability of an organism immune system to provide protection against pathogens. The immune system comprises of Innate and adaptive immune system.

The innate immune system is non-specific immune response to foreign substance and it comprises of physical barriers such as skin, chemicals and immune cells.

Adaptive immune response is specific immune response to particular antigen. It comprises mainly of T and B cells. In adaptive immune response the antibodies are produced and memory is created in exposure to specific antigen. So when next time that foreign antigen enters the body, it will produce the same specific immune response because of memory.
