Climate change and succession both result in a change to the ocean ecosystem. What is succession?
a. Succession is a gradual change to ocean temperatures.
b. Succession is a gradual change to ocean communities.
c. Succession is a rapid change in ocean temperatures.
f
d. Succession is a rapid change to ocean communities.

Answers

Answer:

b. Succession is a gradual change to ocean communities

Explanation:

An ecosystem can undergo changes in it's structure and composition over a particular period of time. This term is called ECOLOGICAL SUCCESSION. Succession is the gradual change that occurs to a community over time. Succession is of two types; primary and secondary succession.

According to the question, climate change and succession are causes of change to the ocean ecosystem. Hence, succession there represents the gradual change that occurs to the structural composition of ocean ecosystem over time.

Answer:

The answer is B - Succession is a gradual change to ocean communities

Explanation:

Think of primary and secondary succession, these processes take time.

____________ a regulatory protein that may bind DNA to inhibit transcription. ____________ a DNA sequence that binds a regulatory protein. ____________a DNA sequence that binds RNA polymerase and regulates transcription. ____________a compound that interacts with another protein or compound to form an active repressor ____________a compound that induces or activates transcription, such as lactose.a. Repressorb. Operator c. Promoterd. Corepressore. Inducer

Answers

Answer:

A repressor is a regulatory protein that may bind DNA to inhibit transcription. An operator is a DNA sequence that binds a regulatory protein. A promoter is a DNA sequence that binds RNA polymerase and regulates transcription. A corepressor is a compound that interacts with another protein or compound to form an active repressor. An inducer is a compound that induces or activates transcription, such as lactose.

Explanation:

Repressor proteins bind to DNA and RNA to suppress target gene expression. A DNA repressor blocks transcription by inhibiting the attachment of RNA polymerase to the promoter sequence, while an RNA repressor bind to the mRNA to block translation of the protein. An operator is a DNA sequence required for the attachment of transcription factors. The genes that are transcribed by the binding of a transcription factor to an operator sequence are collectively referred to as an operon. Operons are generally found in prokaryotes but they also can be found in some eukaryotes including Caenorhabditis elegans and Drosophila melanogaster. An inducer is a molecule that activates gene transcription either by binding to repressors/corepressors (thereby inactivating their functions) or by binding activators. For example, the allolactose act as an inducer of the lac operon.

Aquatic organisms in coastal areas face a variety of predators on land and in the water and air. Which ocean process exposes the coastal aquatic organisms to land-based predators? a. Changing wind patterns alter the ocean currents, changing tide levels. b. Daily tidal patterns leave areas exposed to the land for part of the day. c. The constant wave action generates nutrients that attract predators. d. The ocean conveyor belt raises and lowers the water levels on the coasts.

Answers

Answer:

b

Explanation:

The correct answer as to the ocean process that exposes the coastal organisms to land-based predators would be the daily tidal patterns that leave the coastal area exposed to the land for a part of the day.

Some parts of the coastal areas become exposed to land during certain periods of the day as a result of tidal waves. When this happens, the aquatic organisms occupying these coastal areas become temporarily exposed to land predators who hunt and kill them for food.

Therefore, the correct option is b.

Explanation:

When protein is hydrolyzed, it forms amino acids. Thus, the correct option is A.

What is Hydrolysis?

Hydrolysis may be defined as a chemical process that utilizes the molecules of water that involve the chemical breakdown of a compound.

Amino acids are the monomers of protein. These amino acids are linked together by peptide bonds. But the process of hydrolysis breaks the peptide bond between the amino acid sequences and released them significantly in free form.

Therefore, when protein is hydrolyzed, it forms amino acids. Thus, the correct option is A.

DNA is transcribed to messenger RNA (mRNA), and the mRNA is translated to proteins on the ribosomes. A sequence of three nucleotides on an mRNA molecule is called a codon. As you can see in the table, most codons specify a particular amino acid to be added to the growing protein chain. In addition, one codon (shown in blue) codes for the amino acid methionine and functions as a "start" signal. Three codons (shown in red) do not code for amino acids, but instead function as "stop" signals.
Sort the following ten codons into one of the three bins, according to whether they code for a start codon, an in-sequence amino acid, or a stop codon
AUG, UAG, UAA, UGA, AAA, UGC, AUC, CAC, GCA, ACU

Answers

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.

Hence, using the attached amino acid chart:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

When an enzymatic reaction is in progress, do you expect to see an increase, decrease or no change in each of following: (i) substrate (ii) product (iii) enzyme

Answers

Answer:

During Enzymatic reaction, enzymes binds to a substrate to form a which then forms the product.

Substrate: A reactant in an enzymatic or chemical reaction is called substrate. Product: The final outcome or substance after completion of reaction is called product.Enzyme: Enzyme helps to increase the rate of reaction and act as a catalyst.

Change in shape of substrate, product and enzymes depends on the temperature outside the optimal range which affect bonding between enzyme and substrate. Enzymes definitely changes their size when bind to substrat and the process is called induced fit which increases the rate of reaction.

During an enzymatic reaction, their is an decrease in the concentration of substrate, an increase in the concentration of product, and no change in the concentration of the enzyme.

What is enzymatic reaction?

A reaction, which is mediated with the help of an enzyme is termed as enzymatic reaction. A substance, which functions as a catalyst in living organisms and regulate the rate at which the chemical reactions takes place is known as an enzyme.

The enzymatic reactions follows the lock and key model, in which the free enzyme combines with the substrate and forms the enzyme-substrate complex, this is further catalyzed into the enzyme-product complex, from which the free enzyme and product get discharged. The product never further binds with the free enzyme.

In the reaction, the substrate get used up thus its concentration decreases, while the formation of product takes place thus its concentration increases. However, there is no change in the concentration of the enzyme as it does not get used up in the process.

Thus, in enzymatic reaction, substrate decreases, product increases, and enzyme concentration remains the same.

In most organisms, the end product of glycolysis is pyruvate. Pyruvate still contains a substantial amount of energy, which can be further extracted. Whether the organisms are operating under aerobic or anaerobic conditions determines the metabolic pathway that pyruvate undergoes to produce more ATP. In this tutorial, you will identify the end products of these metabolic pathways.

Answers

Answer:

Pyruvate helps in the production of ATP.

Explanation:

The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.
