k0ka [10]

Answer:

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

Xelga [282]
<h2>c.is the correct option</h2>

Explanation:

Fungi might assist in seed germination by providing the embryos with some of the organic nutrients the fungi have absorbed

  • Fungi is an eukaryote which digests food externally and absorbs nutrients directly through its cell walls
  • Fungi absorb nutrients through following three ways:
  • By decomposing dead organic matter: obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds
  • By feeding on living hosts:fungi live in or on other organisms and get their nutrients from their host
  • Living mutualistically with other organisms: mutualistic fungi live harmlessly with other living organisms;fungal component absorb water and minerals and provide them to algal component which uses them to make food

In dark,moist environment nutrient availability is less hence fungi helps in providing orchid seeds the nutrients which it has absorbed

Which equation is correct according to ohm’s law? r = vi v = i over r. r = i over v. v = ir
OlgaM077 [116]

The equation which is correct according to ohm’s law is v = ir which is denoted as option D.

<h3>What is Ohm’s law?</h3>

This states that the voltage across a conductor is directly proportional to the current flowing through it.

This is deduced as V ∝I where v is voltage and I is current.

V = IR

tigry1 [53]

Answer:

The correct answer is: supraspinatus.

Explanation:

Many muscles insert in the humerus - in its greater tubercle, where the fracture took place, is where three of the four rotator cuff muscles insert: <u>supraspinatus, infraspinatus, and teres minor</u>. Avulsion of the greater tubercle could result in detachment of any of these 3 muscles but if we take into account that the 15-year-old boy had <u>difficulty initiating abduction of the upper limb, we can infer that the damaged muscle is the supraspinatus because its main action is to start the abduction the upper limb</u>.
