Answer:

The rate at which an enzyme catalyses a particular reaction is calculated by the amount of substrate being used up. The concept of a chemical reaction is that the substrate is converted into product with the help of an enzyme.

Rate of reaction= Amount of substrate utilized or product formed/ Time taken

Explanation:

Temperature is an important factor in the deciding of a rate of reaction. The velocity of an enzyme <u>increases with an increase in temperature</u> until and optimum temperature is achieved. After that, the velocity of an enzyme starts <em>decreasing</em> since the enzyme starts to get denatured.

Enzymes work best at a <em>specific pH</em>. If there are changes in pH, the active site of an enzyme gets modified and the rate of reaction decreases. Certain enzymes like pepsin which is in our stomach works at an acidic pH of 2.0.

Summary of hearing: Vibrations cause the cochlea’s membrane to shake. This causes ripples in the ____________, bending the _____
mash [69]

Answer:

1) Basilar membrane

2) Stereocilia or hair cells

3) Nerve cells

4) Auditory

5) Temporal lobe

Explanation:

Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.  

Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.

Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.

Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.

26. Suppose the two guanosine (G) nucleotides in #3 above were changed to two cytosine (C) nucleotides. What is the new amino ac
seropon [69]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be found in the attachment below.

During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow

DNA:   T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A

mRNA:             A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U

Amino Acids:       met --     leu   --   met   --  lys    --   lys    --    Glu   --  Phe

The new amino acid sequence is represented above from the new DNA sequence.

Predict the type of progeny produced by Mendel's crosses between pure-breeding plants with discrete, antagonistic traits, such a
asambeis [7]

Answer:

The progeny produced is 100% heterozygous individuals.

Explanation:

Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.

When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.

If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.

As for its phenotype, it will depend on which allele is dominant over the other.
