Answer:
Optimum Temperature is 35°C
Optimum PH is 7.0.
Explanation:
The optimum temp of enzymes is 20-35°c. They become inactivated at very low temperature and denatured (destroyed) at very high temp i.e. greater than 45°C. Low molecular weight enzymes are comparatively more heat stable.
The optimum pH of most enzymes is pH 7.0 (neutral pH).

What regulates breathing rate and how does the body sense when to breath?
Answers
Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
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
Answers
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.

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
Answers
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.

Given a DNA sequence of ACG, what would be the corresponding RNA sequence? Once you determine the RNA sequence, what would be the corresponding amino acid for the RNA codon? Would a change in one nucleotide of the DNA alter the corresponding amino acid? Explain.
Answers
Answer:
- RNA sequence: UGC
- Amino acid sequence: Cysteine
- Yes, a change in nucleotide will alter the amino acid.
Explanation:
According to this question, a DNA sequence was given as follows: ACG. The process of transcription will produce a RNA sequence from this DNA sequence using complementary base pairing i.e. A-U, G-C etc. Based on this, the mRNA sequence that will result of the DNA sequence above is UGC.
The resulting mRNA transcript is a codon (three nucleotides) that will be used in the process of translation to yield an amino acid. The mRNA sequence: UGC codes for amino acid Cysteine.
- A change in one nucleotide of the DNA will alter the corresponding amino acid because DNA sequence in a particular reading frame is responsible for the production of amino acid. Hence, a slight change in nucleotide might change the reading frame of the sequence and hence give rise to a different amino acid.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.
Answers
Answer:
13,636 seconds = 227.3 minutes = 3.79 hours
Explanation:
The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).
How is dopamine involved in drug addiction?
1) drugs change dopamine into another neurotransmitter.
2) drugs cause the reabsorption of dopamine.
3) drugs decrease dopamine levels in the brain.
4) drugs increase the level of dopamine in the brain
Answer and I will give you brainiliest
Answers
Answer:
The correct answer is - option D.
Explanation:
When an individual takes drugs such as heroin, nicotine, cocaine and methamphetamine increases or promotes the neurochemical reaction that increases the amount of dopamine which is a primary factor in addiction that is secreted by neurons in the brain's reward center.
Higher dopamine levels lead to pleasure in the mind of an addict and it makes people forget the pain or stress and gives immense pleasure.
Thus, the correct answer is - option D.
How are the smallest ocean waves produced?
Answers
Answer:
Ocean waves are usually formed by a distant wind. ... The area which the wind affects the surface is called the fetch. The larger the fetch, the greater the waves produced. the small waves generated by storm winds are often confused and disorganized.
Explanation:
Answer:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
Answers
"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.

How does cooling of magma affect crystal size?
A) Slow cooling creates small crystals
B) Fast cooling creates both large and small crystals.
C) Slow cooling creates large crystals
D) Fast cooling create large crystals
Answers
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Answer:
I learned about this, Uhm...
C is the right answer bc igneous rocks cool and form crystals.
Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.
Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.
Hope this helps :)
