Identify the true statements about introns.a- they code for polypeptide proteinsb- they have a branch site located 20 to 50 nucleotides upstream of the 3' splice sitec- they end with the nucleotides AG at the 3' endd- they begin with the nucleotides GU at the 5' ende- they tend to be common in bacterial genes

Answers

Answer:

The answer is "Option b, c, and d".

Explanation:

In such a gene, Autosomes are also the sequence for code and transposable elements, not the series of encoding. Through the expression of genes, such fragments of its introns are split through protein complexes throughout the translation process. There has been no kenaf fiber in the genomes of prokaryotic cells.

A water wave has a frequency of 10 Hz and a wavelength of 150 m. What is the wave speed? *Equation to use: wave speed (m/s) = frequency (Hz) x wavelength (m)*

Answers

Answer:

Speed of wave = 1500 m/s

Explanation:

Given data:

Frequency of wave = 10 Hz

Wavelength of wave = 150 m

Speed of wave = ?

Solution:

Formula:

Speed of wave = Frequency × Wavelength

Now we will put the values in formula.

Speed of wave = 10 Hz × 150 m

Speed of wave = 1500 m/s

Hz = s⁻¹

Calculate the molar mass of the following:(a)the anesthetic halothane, C2HBrClF3
(b)the herbicide paraquat, C12H14N2CL2
(c)caffein, C8H10N4O2
(d)urea, CO(NH2)2
(e)a typical soap,C17H35CO2Na

Answers

Answer:

a)C2HBrClF3 = 197.35 g/mol

b)C12H14N2CL2 = 229.06g/mol

c)C8H10N4O2 = 194.22g/mol

d) CO(NH2)2=60.07 g/mol

e)C17H35CO2Na = 306.52 g/mol

Explanation:

Molar mass of a compound is equal to the sum of the atomic masses of the constituent elements.

a) C2HBrClF3

$Molar\ mass = 2(At. mass C)+1(at.mass H) +1(At. mass Br) + 1(At.mass Cl) + 3(At.mass F)\n=2(12.01 g/mol) + 1(1.01g/mol)+1(79.90 g/mol) +1(35.45g/mol)+3(18.99g/mol)=197.35g/mol$

b) C12H14N2CL2

$Molar\ mass = 12(C) + 14(H) + 2(N) + 2(Cl)\n\n=12(12.01) + 14(1.01) + 2(14.01) + 2(35.45) = 229.06g/mol$

c) C8H10N4O2

$Molar\ mass = 8(C) + 10(H) + 4(N) + 2(O)\n\n=8(12.01) + 10(1.01) + 4(14.01) + 2(16.00) =194.22g/mol$

d) CO(NH2)2

$Molar\ mass = 1(C) + 1(O) + 2(N) + 4(H)\n\n=1(12.01) + 1(16.00) + 2(14.01)+4(1.01) =60.07 g/mol$

e) C17H35CO2Na

$Molar Mass = 18(C) + H(35) +2(O) + 1(Na)\n\n=18(12.01) + 35(1.01) + 2(16.00) + 1(22.99) =306.52 g/mol$

What is the charge of the most stable ion of bromine?

Answers

The charge on the most stable ion of bromine is - 1.

What is an ion?

A charged atom or molecule is known as an ion. It has a charge because the atom or molecule's number of protons and electrons is not equal. Depending on whether an atom has more electrons than protons or fewer electrons than protons, an atom might become positively or negatively charged.

An atom is referred to be an ION when it is drawn to another atom due to an imbalance in its electron and proton numbers. A negative ion, or ANION, is an atom that contains more electrons than protons. A positive ion is one that has more protons than electrons.

Either there are too many or not enough electrons in a charged atom. Atoms in DS1 are heated to extremely high energy and unstable state. Then, a cathoderay in the thruster chamber discharges electrons, which strike the. Some of the electrons in the atoms in the chamber are stripped or knocked away when the electrons strike them. Plasma is created when a mass of charged, overheated atoms with free electrons.

Therefore, the charge on the most stable ion of bromine is - 1
