Please Answer ASAP, The Assignments In Due Really Soon :) 30 Points!!! The Image Below Shows The Lac

Answers

Answer 1

Answer:

B. Gene expression is influenced by high lactose levels in the environment.

Explanation:

The lactose operon (lac operon) functions for the metabolism and transport of lactose in several bacteria.

Gene expression is influenced by high lactose levels in the environment as genes are expressed in the presence of high level lactose and absence of glucose. High level lactose carry an activator protein called catabolite activator protein (CAP), which let the RNA polymerase do transcription of the operon.

Hence, the correct option is "B".

Answers

Answer:

Epidermis layer is responsible for the protection of meristematic region.

Explanation:

Meristematic region is protected in the stem tip by epidermis which consist of dead layer of cells. Epidermis is the outer layer of stems, leaves, flowers and fruits which is responsible for the protection of inner part from damage. Vascular bundle such as phloem present near the boundary of the stem while the xylem is present in the inside of the stem. In the inside layer of the stem, all the xylem cells are genetically identical while the layer that is present at the edge of the stem is phloem in which all the cells are  genetically identical to each other.

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.

How do animals survive along the deeper parts of the seafloor? A They feed at the surface. B They feed on each other. C They photosynthesize.

Answers

Answer:

Explanation:

There are several ways deep ocean animals survive in such an enviournment..Food is scare in much of the deep sea, in parts because photosynthesis only thakes place at the ocean's surface where there's sunlight. Most animals cope with this by begin very small and meeding less to eat of by growoing very slow..

Answer:

the answer is They photosynthesize..

Explanation:

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

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.

Answer:

The answer is ATP, ADP

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.

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.
