Which RNA molecule is matched with its correct function?
Answer:
Which class of RNA is correctly paired with its function? Transfer RNA (tRNA): attaches to an amino acid. What is the difference between the template strand and the nontemplate strand? The template strand is the DNA strand that is transcribed into an RNA molecule, whereas the nontemplate strand is not transcribed
the dna structures
Answer:
Each DNA strand is composed of nucleotides—units made up of a sugar (deoxyribose), a phosphate group, and a nitrogenous base. Each strand of DNA is a polynucleotide composed of units called nucleotides. A nucleotide has three components: a sugar molecule, a phosphate group, and a nitrogenous base. Explanation:

In normal cells the amino acid phenylalanine attaches to tRNAs with the anticodon AAA. The enzyme aminoacyl-tRNA synthetase catalyzes the reaction that attaches the amino acid to the correct tRNA. Assume that a mutation occurs in the aminoacyl-tRNA synthetase enzyme and causes it to attach lysine instead of phenylalanine to tRNAs with the anticodon AAA. What will be the consequence of this mutation for the translation process
Answer:
Aminoacyl-tRNA bond is hydrolyzed.
Explanation:
The consequence of this mutation for the translation process is the hydrolysis of aminoacyl tRNA bond occur. If the incorrect amino acid is attached to other molecule as a result of this reaction, the aminoacyl-tRNA bond is hydrolyzed. This incorrect binding of amino acid occur because of mutation in the aminoacyl-tRNA synthetase enzyme that leads to its hydrolysis.

1) All of the following are examples of an asexual reproduction except
a) Cloning technique b) Forming zygots
c) Runners technique I
d) Tuber technique in the potato
Answer:
b) Forming zygots
Explanation:
A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.
Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

Explain what causes a muscle to go into rigor mortis. Your answer should include the circumstances which cause it, as well as why those circumstances cause the effect (what is happening in the muscle at a molecular level which causes the stiffness).
Explanation:
Rigor mortis develops as the body's energy source (adenosine triphosphate [ATP]) is depleted. Muscle fibers require ATP for relaxation; once depleted, actin and myosin proteins remain complexed, resulting in stiffening of the muscles..

Do natural hazards always become natural disasters? What are some things that people can do that might influence whether or not a natural hazard will become a natural disaster?
Answer:
SLLLW
Explanation:
1.) A person walks 12.5 km in 1.9 h. What is the person's
average velocity in km/h and m/s?
Answer:
1. 6.56 km/hr
2. 1.83 m/s
Explanation:
The average velocity/speed can be calculated using the formula;
Average speed/velocity = distance/time
According to the information provided in the question, distance = 12.5km, time = 1.9h
Average velocity in km/hr = 12.5/1.9
= 6.578
= 6.56km/hr
However, in order to calculate the average speed in m/s, we have to convert distance in km to m, and time in hour to seconds.
1km = 1000m
12.5km = 12.5 × 1000
= 12500m
1 hour = 3600seconds
1.9hours = 1.9 × 3600
= 6840seconds
Average velocity = 12500/6840
= 1.827
= 1.83m/s
A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

S. Give three reasons to explain why transpiration occurs mainly through leaves
6. Explain how sunken stomata lower the rate of transpiration
11
with
ftri
Answer:
Due to stomata.
Explanation:
Transpiration occurs mainly through leaves because of the presence of stomata n the lower side of the leaves. Transpiration refers to the loss of water from the body of plants so leaves has small pores which is used by the plant to regulate internal temperature. Sunken stomata lower the rate of transpiration because it is not directly exposed to the surface which protects the escaping water vapor due to air.
