Answer:

This is an example of Green design.

Explanation:

Green design can be described as a method in which any building project is made by minimizing the harmful effects of construction on humans and environment. Green design is a sustainable design which is better for the economy too. In a green design, eco- friendly materials are used for construction works.

In the scenario discussed in the question, an engineer is using bamboo as a building material due to its eco- friendly features. Hence, it is an example of green design.

Pickle is not stored in the metal vessel for long time.why?

larisa86 [58]

Answer:

Ummm a pickle is stored in glass container usually in the fridge

Explanation:

so the pickles dont go bad they go in the fridge so they dont mold. if you were to put them in a metal container they would get very cold when you put them in the fridge.

As the two parental (template) DNA strands separate at a replication fork, each of the strands is separately copied by a DNA pol

Lapatulllka [165]

Answer:

Synthesis of leading strand:

daughter strand elongate towards replication fork

only one primer is needed

made continuously

Synthesis of the lagging strand:

multiple primers needed

daughter strand elongates away from replication fork

made in segments

Synthesis of both:

synthesized in 5' to 3'

Explanation:

The replication of DNA involves the unwinding of the double helix structure by the helicase enzyme after which RNA primer binds to form a bubble known as the replication fork.

DNA can only be replicated in the 5' to 3' direction because the polymerase that is responsible for the elongation of new strands can only add nucleotides in the 5' to 3' direction.

Hence, the leading strand is replicated continuously in this direction while the lagging strand is replicated discontinuously or fragments known as the okazaki fragments. The discontinuous replication of the lagging strand therefore requires different primers biding at multiple sites on the DNA strand.

Because of the nature of replication of the lagging strand, the elongation of the fragments moves away from the replication fork while that of the leading strand moves towards the replication fork.

Upon decomposition, a sample of sodium bicarbonate produces 0.0118 g of sodium carbonate, Na2CO3. How many grams of water does i

Naily [24]

Answer:

2.00 × 10⁻³ g

Explanation:

Step 1: Write the balanced decomposition reaction

2 NaHCO₃ ⇒ Na₂CO₃ + CO₂ + H₂O

Step 2: Calculate the moles corresponding to 0.0118 g of Na₂CO₃

The molar mass of Na₂CO₃ is 105.99 g/mol.

0.0118 g × 1 mol/105.99 g = 1.11 × 10⁻⁴ mol

Step 3: Calculate the moles of H₂O produced with 1.11 × 10⁻⁴ moles of Na₂CO₃

The molar ratio of Na₂CO₃ to H₂O is 1:1. The moles of H₂O produced are 1/1 × 1.11 × 10⁻⁴ mol = 1.11 × 10⁻⁴ mol.

Step 4: Calculate the mass corresponding to 1.11 × 10⁻⁴ moles of H₂O

The molar mass of H₂O is 18.02 g/mol.

1.11 × 10⁻⁴ mol × 18.02 g/mol = 2.00 × 10⁻³ g

What will happen to convection currents in the mantle if earths interior eventually cools down?

VLD [36.1K]

If the core were to cool completely, the planet would grow cold and dead. It also would get a little dark: Power utilities pull radiant heat from Earth's crust and use it to heat water, the steam from which powers turbines to create electricity.Cooling also could cost us the magnetic shield around the planet created by heat from the core. This shield protects Earth from cosmic radiation. The shield is created by a convection process caused by constantly moving iron. Like the planet itself, Earth's core is constantly spinning. Some scientists think it's moving even faster than the rest of the planet. The friction converts kinetic energy into electrical and magnetic energy that forms the field, which deflects harmful, charged particles emanating from the sun toward the north and south poles. Your welcome :)

How can the chemical properties of an element help determine the types of materials it can form?

AleksandrR [38]

<h2>Answer:</h2>

The quantity of protons likewise decides the character of the component. Electrons have a negative charge. The furthest or valence electrons of a particle are the ones that partake in synthetic responses. A component's substance properties rely upon its valence electrons.

The general properties of issue, for example, shading, thickness, hardness, are instances of physical properties. Properties that portray how a substance changes into a totally extraordinary substance are called synthetic properties. Combustibility and consumption/oxidation obstruction are instances of compound properties.

Reactivity with other chemicals.

Toxicity.

Coordination number.

Flammability.

Enthalpy of formation.

Heat of combustion.

Oxidation states.
