Answer:
The correct answer is <em>d. The nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose.</em>
Explanation:
The nucleoside triphosphates are components of DNA (deoxyribonucleic acid) so they are composed by a nitrogenous base (adenine, guanine, thymine or cytosine) and a deoxyribose sugar. In contraposition, ATP (adenosine triphosphate) is composed by the nitrogenous base adenine and a ribose sugar along with three phosphates groups. Unlike ribose, deoxyribose is a 5-carbon sugar which lack of an oxygen atom in C2 position.
D. the reflection of each concave lens makes the object appear larger
Answer:
1.54×10^20 atoms
Explanation:
It's done by using the relation
N=n×L where,
N = number of entities present
n= amount of substance (mole)
L= Avogadro's constant which is 6.02×10^23
now from the question, given
n=0.000256
And L=6.02×10^23
N= 0.000256×6.02×10^23
N= 1.54×10^20 atoms
The name of CuO is Copper(II) oxide have the two most common oxidation states of copper are +2 and +1.
<h3>What is copper oxide used for?</h3>
Copper oxide is a trace element for the zootechnical and agricultural sector. Cupric oxide is also used as a raw material for the production of catalysts and pigments in the field of ceramics, glass and plastics.
This compound makes two different types of bonds being the hydrogen bond when it's a hydrogen and covalent bond when we have an oxygen or a nitrogen.

Answer:
V₂ =279.4 cm³
Explanation:
Given data:
Initial volume = 260 cm³
Initial temperature = 22.0°C
Final temperature = 44.0°C
Final volume = ?
Solution;
22.0°C (22+ 273 = 295k)
44.0°C(44+273 = 317k)
Formula:
According to Charles's law
V₁/T₁ = V₂/T₂
Now we will put the values in formula:
V₂ = V₁×T₂ / T₁
V₂ = 260 cm³ × 317k / 295k
V₂ = 82420 cm³. k / 295k
V₂ =279.4 cm³
