Two resistors or resistance 2ohms and 4 ohms are connected in series and then in

Biology
1 answer:
kari74 [83]4 years ago
3 0

Answer:

Ratio = 9 : 2

Explanation:

We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.

First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:

Resistance (Equivalent) = R₁ + R₂ = 6 ohms

When these are connected in parallel, equivalent resistance becomes:

1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4

1 / Resistance (Equivalent) = 3/4

Resistance (Equivalent) = 4/3

Ratio = R(Series)/ R(Parallel)

Ratio = 6 : 4/3

Ratio = 18 : 4

Ratio = 9:2

Arachidonic acid is the raw material for synthesis of
RUDIKE [14]

Answer:

The correct answer is E. Arachidonic acid is the raw material for synthesis of eicosanoids.

Explanation:

Arachidonic acid is an essential omega-6 fatty acid formed by a 20-carbon chain with four double bonds. The presence of double bonds causes this molecule to have several sites that can be oxidized, allowing the formation of different lipids with different biological activities.

Arachidonic acid is part of phospholipids in cell membranes, and is the precursor of eicosanoid biosynthesis. Arachidonic acid can be synthesized from linoleic acid, one of the essential fatty acids required by most mammals.

An area of raised land in the middle of a river. Mountains and glacier in the distance. A geologist finds this ridge of sediment
Nadusha1986 [10]

A moraine is a landform feature which is formed by the glacier retreating. The ridge of sediments that geologists found has a feature namely moraine.

<h3>What is moraine?</h3>

The materials usually soil or rocks left behind by the glaciers are called moraine.

Just like rivers that carries all sorts of debris and silt and eventually builds up to form deltas, similarly glaciers moves all sorts of dirt and boulders that assembles to form moraines.

As the geologist found a ridge of sediments and notices a glacier in the distance so this is the moraine.

Thus, the correct answer is C.
