In some species of plants, mutations can cause a plant to have different patterns on their leaves, such as gold edges or white s

tripes. Plants with different patterns grow to the same size and produce offspring with similar patterns. However, these plants can have high mutation rates. As a result, a group of related plants can exhibit many patterns.

Answer:

In many plants species , a plant have different patterns on their leaves. It is because of mutations which occurs due to change in the DNA or genetic makeup because of environmental factors such as UV light and other substances.

Explanation:

Mutation refers to the sudden change which occurs in the genetic makeup of the cell due to the exposure to harmful radiations such as UV radiation and gamma radiation. In Plant cells, mutation also occurs due to the external environment. Sometimes it occurs naturally and sometimes due to certain radiation or smoke.

The distance between two bonded atoms (the bond length), is usually in units of picometers, where 1.00 m = 1.00 x 1012 pm (or 1.
8090 [49]

Answer:

7.52 × 10⁻¹⁴ mi

Explanation:

Step 1: Given data

Bond length between two carbon atoms (l): 121 pm

Step 2: Convert "l" to meters

We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.

121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m

Step 3: Convert "l" to miles

We will use the conversion factor 1.00 mi = 1609.34 m.

1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi

How many grams of sodium benzoate, C H CO Na, have to be added to 1.50 L of a 0.0200 M solution of benzoic acid, C H CO H, to ma
Dmitrij [34]

Answer: 2.8275grams

Explanation: A buffer is made btw a weak acid and it salt. In a solution made by dissolving a weak acid in solution, equilibrium is set up btw ionised and unionised ion. For Benzoic acid

C6H5COOH....> C6H5COO- + H+

Ka = [C6H5COO-] [H+]/ [C6H5COOH].......(1)

using Ka = 6.5× 10^-5, [C6H5COOH] = 0.02M. PH= - log[H+] ....> [H+]= 10^-4M.

Putting the values in(1)

[C6H5COO-]= 6.5× 10^-5 × 0.02/ 10^-4

[C6H5COO-] = 0.013M = Molarity of sodium benzoate

Mole(C6H5COONa) = 0.013 × Volume = 0.013mol/litre × 1.5 litre

Mole(C6H5COONa) = 0.0195mol

Mass(C6H5COONa) = 0.0195 × Molar mass

Mass(C6H5COONa) = 2.8275g

The limiting reactant in a reaction a. is the reactant for which there is the least amount in grams b. is the reactant which has
Shalnov [3]

Actually the correct answer must be:

The limiting reactant in the reaction is the one which has the lowest ratio of moles available over coefficient in the balanced equation

 

This is because the actual mass or number of moles of the reactant does not directly dictate if it is a limiting reactant, this must be relative to the other reactants.

 

So the answer is:

e. none of the above
