How would someone measure the effect of pH on the rate<br> ofenzyme reaction?
wlad13 [49]

Answer:

It can be determined by measuring product appearance or reagent disappearance also enzymatic activity (described below )

Explanation:

Effect of pH on enzymatic activity

PH effect: affects the state of dissociation of the groups, although all proteins are not affected in the same way because some do not have dissociable groups. Most enzymes have an optimal pH. If there are small changes in pH, the enzyme is not denatured. The pH can affect in two ways:

The substrate binding is better or worse than before.

That affects the catalytic speed of the reaction.

The enzymatic speed is measured in M ​​/ t and the enzymatic activity in mol / t, and the international unit μmol / min, amount of enzyme that transforms a micromol from substrate into product in one minute under optimal conditions. Another unit is the enzymatic amount that is required to transform 1 mol / s and is called katal.

Name four factors that affect population growth then explain how each factor contributes to population growth
daser333 [38]

Answer:

Contraceptive Education/Availability, Healthcare, Country Development, and Political Climate

Explanation:

When people are educated about proper contraceptive use they can still have sex without the consequence of pregnancy. The availability of contraceptives goes hand in hand with contraceptive education.

Advanced healthcare can help prevent disease through immunizations and further the life expectancy of the country's population. Hand washing can significantly lower the spread of disease.

The lower the development of a country the higher the birth rate is, while the higher the developed countries have a lower birth rate and their life expectancy is much longer.

The political climate of a country can greatly affect the population growth. The more negative the political climate is usually causes a smaller birth rate. For example when China implemented the one child policy their population growth declined;.

Focus on the evolution of horn size in the Bighorn sheep population from 1950 to present. What would you predict would happen if
dalvyx [7]

Answer:

The correct answer is option e) "Over time, we could see an increase in the H1 allele frequency".

Explanation:

The bighorn sheep (Ovis canadensis) is a species that is a very attractive for hunters because of its long horns. This negative human influence has make that bighorn sheep with long horns struggle to survive and reproduce. Horn size in bighorn sheep is determined primarly by a gene called HRN, which has two alleles H1 (for long horns) and H2 (for smaller horns). if hunting were discontinued for bighorn sheep in a large population we can predict that over time, we could see an increase in the H1 allele frequency, because in this population bighorn sheep with long horns will have better chances of surviving.

What is a stop codon​
storchak [24]

Answer:

In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein

Explanation:

Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.
