What is the velocity of a car traveling north, 100 meters in 25 seconds? Explain how you got that answer

Answers

Answer 1
Answer:

Answer:

4 meters/second (4 m/s)

Explanation:

velocity=distance/time

distance= 100 meters

time= 25 seconds

v=100m/25sec = 4 meters/second (4 m/s)

Absolute zero temperature is not the zero energy temperature.explain​

Answers

The absolute zero is the temperature at which molecular motion ceases i.e translational kinetic of molecules become zero, but the molecules possess the potential energy, according to the Kinetic theory of gases. Thus, the absolute zero is not the zero energy temperature.

Transcription occurs along a ____ template forming an mRNA in the ____ direction. (0.5 pts.) A) 5' to 3'; 5' to 3' B) 5' to 3'; 3' to 5' C) 3' to 5'; 5' to 3' D) 3' to 5'; 3' to 5'

Answers

Transcription occurs along a 3'-5' template forming an mRNA in the 5'-3' direction.

WHAT IS TRANSCRIPTION:

  • Transcription is the process by which a mRNA molecule is synthesized from a DNA template.

  • Transcription occurs in the nucleus of eukaryotic organisms where the information stored in the DNA molecule is used to produce a complementary mRNA sequence that conveys it to the ribosome.

  • Transcription occurs in the 3'-5' direction, and since the mRNA molecule is complementary, it'll be in the 5'-3' direction.

Therefore, transcription occurs along a 3'-5' template forming an mRNA in the 5'-3' direction.

Answer:

3' to 5'; 5' to 3'

Explanation:

The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA.  The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.

A woman, Penelope, has a sister with polycystic kidney disease (ARPKD), which is inherited in an autosomal recessive mode. Penelope does not have the disease, and both of her parents do not have ARPKD. Penelope marries a man from Europe who does not have ARPKD. There is no information about whether this disease runs in his family, but 96% of the population does not have ARPKD (assume the disease is in Hardy-Weinberg equilibrium). What is the probability that they will have a child with ARPKD?
A) 0.25
B) 0.15
C) 0.05
D) 0.04
E) there is not enough information to answer this question

Answers

Answer:

D) 0.04

Explanation:

Assuming that a is the recessive allele when homozygous that causes the polycystic kidney disease and A is the dominant one:

Since Penelope's sisters has the disease, she must be homozygous recessive (aa). Her parents must both be Aa (otherwise her sister wouldn't have inherit the disease).  So, the probability of Penelope of being heterozygous (Aa) is 0.5.

On the other hand, the probability of having the disease in the population is 0.04 (1 minus the probability of not having the disease which is 0.96). This, according the Hardy–Weinberg principle, in the population would represent  the genotype frequency q^(2). So, the allele a would have a frequency √(q) = √(0.04) = 0.2. Since the gene has only two alleles, all alleles must be either A or a , therefore p + q = 1. So, the A population's frequency is p = 1 - q = 1 - 0.2 = 0.8.

The European man's probability of being Aa (doesn't have the disease but can carry the disease allele) is 2pq = 2 x 0.8 x 0.2 = 0.32.

The probability of Penelope and the European man of having an ill kid (assuming they both are Aa) is 0.25.

Finally, given the Penelope's probability of being Aa (0.5), the European man's 's probability of being Aa (0.32) and the probability of having a kid homozygous recessive aa (0.25) = 0.5 x 0.32 x 0.25 = 0.4 is the probability that they will have a child with ARPKD.
