When a plant experiences heat, what part of a plant allows for the response to take place?

Answer and Explanation:

Given that

Length of race = 5km

Maximum speed = 45 yards

Based on the above information,

We transform the yards to kilometer i.e.

1 km = 1093.613 yards

And,  

x = 45 yards

So,

1093.613 × x = 45

x = 45 ÷ 1093.613

x = 0.0411480 km

Where

x = Maximum length for which the maximum speed demonstrated in kilometers is sustained.

So, we concluded that Lamor cannot go for the overall 5km as he maintained till 0.0411 km

Explanation:

Charles' law gives the relationship between the volume and the temperature of the gas. Mathematically,

Volume ∝ Temperature

i.e. \(\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\)

We have, V₁ = 1.6 L, T₁ = 278 K, T₂ = 253, V₂=?

\(V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{1.6\times 253}{278}\\\\V_2=1.45\ L\)

So, the new volume is 1.45 L.

Explanation:

The reagents and intermediates involved in the other order of synthesis of dec-3-yne, with the ethyl group added first and the hexyl group added last, include H-CEC-CH, CH3CH2Br, NaNH2, CH3CH2I, and Na.

To synthesize dec-3-yne in the other order, the key steps involve adding the ethyl group first and then introducing the hexyl group. The process starts with the reagent H-CEC-CH, which serves as the starting compound or intermediate.

The H-CEC-CH compound is then subjected to nucleophilic substitution using CH3CH2Br (ethyl bromide) and NaNH2 (sodium amide) to replace one of the hydrogen atoms with an ethyl group, resulting in CH3CH2CEC-CH.

This intermediate is then further modified by reacting with CH3CH2I (ethyl iodide) and Na to introduce the ethyl group, leading to CH3CH2CEC-CH2CH2I. Finally, the hexyl group is added using appropriate reagents in subsequent steps, which are not specified in the given question.

Explanation:

To tightly pachage a single molecule of dna

The formula of the molecule made by adding one fructose to a molecule of lactose is C24H42O21.

When fructose is added to lactose, a glycosidic bond forms between the fructose and lactose molecules. Lactose is a disaccharide consisting of one molecule of glucose and one molecule of galactose, linked by a β-glycosidic bond. Fructose, on the other hand, is a monosaccharide. The addition of one fructose molecule to lactose results in the formation of a trisaccharide. The fructose molecule attaches to the lactose molecule at the hydroxyl group of either the glucose or galactose unit, forming a new glycosidic bond.

The formula of the resulting molecule, C24H42O21, represents the combined molecular formula of the fructose, glucose, galactose, and the water molecule that is released during the formation of the glycosidic bond. This trisaccharide retains the general structure and properties of its constituent sugars but possesses a unique arrangement due to the formation of the glycosidic bond.

Within this group of elements, we have monovalent cations (Cs+ for example), divalent cations (Ca2+), but in the transition metals we find multivalent or polyvalent ions, like Fe, that can be Fe2+, Fe3+, and Fe4+, so these elements are able to carry different charges as cations, more examples of these multivalent ions are Copper, Zinc, Manganese, and many more.

Answer: \(1.6\times 10^4\)

Explanation:

Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example : 5000 is written as \(5.0\times 10^3\)

In division , the result would contain the same number of significant digits as there in the least precise number , thus the answer would have 2 significant digits.

Answer:

\(\boxed {\boxed {\sf SO_3}}\)

Explanation:

An empirical formula shows the smallest whole-number ratio of the atoms in a compound.

So, we must calculate this ratio. Since we are given the amounts of the elements in moles, we can do this in just 2 steps.

The first step is division. We divide the amount of moles for both elements by the smallest amount of moles.

There are 0.300 moles of sulfur and 0.900 moles of oxygen. 0.300 is smaller, so we divide both amounts by 0.300

The next step is writing the formula. We use the numbers we just found as the subscripts. These numbers go after the element's symbol in the formula. Remember sulfur is S and there is 1 mole and oxygen is O and there are 3 moles.

This formula is technically correct, but we typically remove subscripts of 1 because no subscript implies 1 representative unit.

The concentration of the NaOH solution is approximately 0.12 M. To determine the concentration of the NaOH solution, we can use the concept of stoichiometry and the balanced chemical equation for the reaction between NaOH and HCl:

NaOH + HCl -> NaCl + H2O

First, let's determine the amount of HCl used in the titration. Since the volume of the HCl solution is 24.53 mL and its concentration is 0.250 M, we can calculate:

Amount of HCl = Volume × Concentration

             = 24.53 mL × 0.250 mol/L

             = 6.1325 mmol

According to the balanced equation, the stoichiometric ratio between NaOH and HCl is 1:1. Therefore, the amount of NaOH in the solution is also 6.1325 mmol.

Now, let's calculate the concentration of the NaOH solution:

Concentration of NaOH = Amount of NaOH / Volume of NaOH solution

                    = 6.1325 mmol / 50.00 mL

                    = 0.1227 mol/L

Rounding to the appropriate number of significant figures, the concentration of the NaOH solution is approximately 0.12 M.

The given statement "Ethanol molecules are held together by covalent bonds, while water molecules are held together by hydrogen bonds" is True because Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration.

In the case of ethanol, the carbon (C) atom shares electrons with the hydrogen (H) atoms and the oxygen (O) atom, forming covalent bonds within the molecule. These covalent bonds hold the atoms together in a stable structure.

On the other hand, hydrogen bonds are a specific type of intermolecular force that occurs between molecules. In water, the hydrogen atoms within each water molecule are bonded to the oxygen atom through covalent bonds. However, the positively charged hydrogen atom in one water molecule is attracted to the negatively charged oxygen atom in a neighboring water molecule.

This attraction forms a hydrogen bond between the two water molecules, creating a network of hydrogen bonds in liquid water. So, in summary, ethanol molecules are held together by covalent bonds within the molecule, while water molecules are held together by hydrogen bonds between the molecules.

This peptide is positively charged at physiological pH. In conclusion, SDEKAINVKWQLA and SDEKAINVKWQHA are neutral at physiological pH, SEERAINVAWQHA is negatively charged, and SDEK is positively charged.A peptide is a short chain of amino acids that are joined together with peptide bonds.

The nature of a peptide's charge depends on the overall charges of the amino acids in the sequence. At physiological pH, amino acids will either be positively charged, negatively charged, or neutral, depending on their side chains. Let's examine the peptides provided to determine their charges at physiological pH:SDEKAINVKWQLA: This peptide contains a mix of amino acids with positively charged, negatively charged, and neutral side chains. However, the positively charged amino acid (lysine) and the negatively charged amino acid (aspartic acid) are present in equal amounts.

Therefore, this peptide is considered neutral at physiological pH.SDEKAINVKWQHA: This peptide is similar to the first one but has one less amino acid (alanine instead of leucine at the end). It contains the same number of positively charged and negatively charged amino acids, and so it is also neutral at physiological pH.SEERAINVAWQHA: This peptide contains three negatively charged amino acids (aspartic acid and glutamic acid) and only one positively charged amino acid (lysine). Therefore, the peptide overall is negatively charged at physiological pH.SDEK: This peptide contains both positively charged (lysine) and negatively charged (aspartic acid) amino acids. However, there are more positively charged amino acids in the peptide than negatively charged ones.

The major product produced through bromonium ion intermediate is 1,4-dibromobenzene.

It is also possible that a side reaction could occur in this reaction. The stilbene and hbr will react with each other to form 1,4-dibromobenzene and hydrogen peroxide, which can be further oxidized to produce carbon dioxide gas.

However, the reaction conditions are not ideal for producing dibromotoluene. The most important thing to remember about this reaction is that hydrobromic acid is added to stilbene first, and then hydrogen peroxide is added afterwards. If stilbene and hbr reacted with each other, there would be no other molecules involved in the reaction because they both contain bromine.
