A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car's acceleration is

1 answer:
-BARSIC- [3]2 years ago
4 0

Answer:

3 meter / second square.

Explanation:

The acceleration is defined as change in velocity over a period of time interval. Mathematically it can be written as,

acceleration = change in velocity / time

acceleration =  16- 4 (meters/second) / 4 seconds

acceleration = 12 meters/second / 4 seconds

acceleration =  3 meter / second square.

So the answer shows that the car accelerates 3 meter / second square.

MatroZZZ [7]

The correct answer is: <em>tibia</em>

The femur, also known as the thigh bone, is one of the longest bones of the human body. The distal point of the femur refers to the area furthest away from its point of attachment, which in this case is the hip joint (please refer to the attached image). When referring to the image, you can see that the distal end of the femur articulates with the bone known as the tibia or shin bone. The tibia is the larger of the two bones located at the distal end of the femur. The tibia includes the knee and ankle joints. Therefore, the bone that articulates with the distal end of the femur is the tibia.

Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phospha
SVEN [57.7K]

Answer:

30 protein molecules per mRNA molecule

Explanation:

In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

Reika [66]

The option are not given and the options are:

Proteins are denatured by breaking covalent bonds.

Linear molecules like DNA are inherently stable.  

Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.

Answer:

The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

Explanation:

Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.

DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.
