Which of these modes of transmission require a bodily opening either natural or artificial?

Biology

Pavel [41]3 years ago
6 0

Answer:

Answer:

Vectors-These are diseases transmission which involves the piercing of the skin-vectors penetration  e.g by mosquito. ticks.

Air borne which involves entry through the nasal passages, mouth, eyes to reach the body  the respiratory tracts and the blood.

Blood borne diseases are  transmitted from e.g piercing of the skin by  contaminated objects needles, broken glass. If there is an opening in the skin these transmission is also possible.

Sexual can be transmitted through open sores at the genitals.or  use of  contaminated needle by infected subject. Sores in the mouth during kissing may be another route

food borne or water borne needs to enter through natural opening of the mouth to reach the body fluids and the blood through the GIT.

Contact diseases does not necessarily need a direct opening for transmission . rather there should be a direct contact between the infected individual and the other. Sometimes a direct contact between the two is not need. e.g common cold, chicken pox , influenza , etc.

How is constructing a perpendicular bisector similar to constructing an angle bisector? how is it different?.
ruslelena [56]

An angle bisector is a line segment that splits an angle into two equal halves while a perpendicular bisector is a line segment that divides the other line segment that is opposite to it perpendicularly.

  • Angle bisector and perpendicular bisector are similar as the angle is split in two by both.
  • Perpendicular and angle bisectors differ in the way that an angle bisector is not required to make a perpendicular angle with the opposite side, but a perpendicular bisector must.
  • The perpendicular bisector makes a right angle from a horizontal line, in contrast to the angle bisector, which divides an angle in half. They both "divide" the object in two.
  • A line known as a bisector divides an object into two equally sized portions. A line that cuts through an angle to produce two identical angles is known as an angle bisector.
  • For instance, if we establish an angle bisector with a 90-degree angle, the line that passes across the angle will produce two new 45-degree angles.

Two students studying physiology taste a known "bitter" substance, and both report sensing bitterness. They then sample another
Mama L [17]

Answer:

Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particles protein receptor

Explanation:

The sensory organs helps to respond to the change in the external and internal environment. The five main types of sense organs are eyes, ears, nose, skin and tongue.

Tongue contains different types of taste buds and taste receptors that helps to distinguish between the different types of food. The receptors are mainly responsible for the taste detection. The student B is unable to taste the bitter molecule because they lacks the receptor.

Thus, the correct answer is option (c)
