Since, the substances are not given in the questions. The common examples will be explained in the answers.
Answer:
Peripheral membrane proteins may be defined as the proteins that are present on the periphery of the plasma membrane. These proteins play an important role in the transfer of the specific molecules.
Different peripheral membrane proteins that are associated with the plasma membrane are spectrin, actin, protein Kinase C and fibrous proteins. Protein Kinase C play important role in signal transduction and actin and spectrin helps in the attachment of the substances with matrix.
C is The correct answer because when wave refraction occurs there is a change in the depth of the water.
If it is the abdomen and not the stomach area i would say its from the heat. if you've ever seen a dead animal on the side of the road over the course of a few days, they start to swell from the sun beating down on them all day.
Answer: The correct answer is -
A. Sense strand of DNA, substituting uracil for thymine.
Explanation:
Transcription is a process of formation of mRNA (messenger RNA) using a DNA template with the help of enzyme RNA polymerase.
In this process, ribonucleotides are added by RNA polymerase in 5' to 3' direction (that is antiparallel to the direction of template DNA) in a complementary manner.
For Adenine, uracil is added and for Cytosine, Guanine is added in mRNA. This produces the mRNA transcript matching the sense strand of DNA (that is complementary to antisense or template DNA).
Thus, option A) is the right answer.
Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams
