Explain how and when the rule of multiplication and the rule of addition can be used to determine the probability of an event. E

AysviL [449]

Answer:

Addition used for 'either or' events , Multiplication used for 'and' events

Explanation:

Addition is used when Probability is of 'one event or other event'

Multiplication is used when Probability is of 'one event & other event'

Ex : Probability of A winning = 0.4

Probability of B winning = 0.3

Probability (A or B winning) = 0.4 + 0.3 = 0.7

Probability (A & B winning) = 0.4 x 0.3 = 0.12

Why is it important for ectoparasites to stay undetected by their host?

melomori [17]

Ectoparasites cause diseases in humans and animals, so to know the format of detecting it we need to know that ......

<h3>Ectoparasite</h3><h3 />

Parasitism is defined as an interaction where a parasitic organism obtains resources through one or several host individuals, causing damage and reducing its fitness. The endoparasite is a type of parasite that lives inside the host's body (from the Greek endos, inside), while the ectoparasite is one that lives on the external surface of its host (from the Greek ectos, outside). Thus, the ectoparasite does not need to lodge inside the host organism to feed, presenting a partial metabolic dependence. Some examples of ectoparasites are:

Lice
Ticks
and Fleas.

<h3>Strategies of ectoparasites</h3>

Each parasite has particular strategies and adaptations used to extract nutrients from their hosts. In ectoparasites these adaptations can often be seen as changes in the oral apparatus, allowing them to penetrate the skin surface and feed on the host's nutrients. Scabies is a skin disease caused by the ectoparasite Sarcoptes scabiei. In order to obtain nutrients for its survival, the parasitic organism burrows into the skin of the host, unlike ectoparasites such as the louse, which pierce the surface and only insert its mouthparts to extract food.

With this information we can say that the ectoparasites adapt to the host so that it is not noticed and for a better absorption of nutrients from the host, they remain undetectable not to be removed, so that they are not disconnected from their food source as they are in the vast majority visible to the eye.
