Answer:
C. A chain of amino acids
Explanation:
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. ... These proteins bind and carry atoms and small molecules within cells and throughout the body.
A mutation that inactivates the regulatory gene of a repressible operon in an E. coli
cell would result in
a. continuous transcription of the structural gene controlled by that regulator.
b. complete inhibition of transcription of the structural gene controlled by that
regulator
c. irreversible binding of the repressor to the operator.
d. inactivation of RNA polymerase by alteration of its active site.
e. continuous translation of the mRNA because of alteration of its structure.
Question
Final answer:
A mutation inactivating the regulatory gene of a repressible operon leads to uninterrupted transcription of the regulated structural genes, due to the repressor protein no longer being able to inhibit RNA polymerase.
Explanation:
A mutation that inactivates the regulatory gene of a repressible operon in an E. coli cell would result in continuous transcription of the structural gene controlled by that regulator. This is because the repressor protein, which is coded by the regulatory gene, can no longer bind to the operator. This unbound state leaves the RNA polymerase able to bind to the promoter freely and thus transcribe the structural genes without interruption.
Dyhybrid crosses are crossed between two parents with two different heterozygous genes true or false
Answer:
The statement is False.
Explanation:
Dihybrid cross is a type of cross that occur between two different genes which differ in their traits.The cross between homozygous dominant and homozygoys recessive traits results in 1:0:0:0 phenotypic ratio. The resulting offspring will have dominant phenotype but will have carriers of recessive phenotype.What is one advantage wind power has over solar power?

Answer:I think the answer is D
solor palpnles take up an whole Feild while a wind turbine would‘t take up nearly as much.
Explanation:
Wind turbines take up less land space than solar cells is one advantage wind power has over solar power.
What is wind turbines?Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
Wind flow patterns and speeds vary greatly across the United States and are modified by bodies of water, vegetation, and differences in terrain. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water).
Therefore, Wind turbines take up less land space than solar cells is one advantage wind power has over solar power.

Rather than pay for an oil change at the service station, Justin decides to do the job himself. He drains the used oil
and antifreeze directly into the ground in the alley beside his house. After several years, he notices there are no
more frogs in the pond behind his house. What type of pollution is demonstrated in this real world example?
Toxic
Sediment
Nutrient
Bacterial
Answer:
The answer is: Toxic Pollution
Explanation:
"Toxic pollution" refers to contaminating the surroundings with toxic or hazardous chemicals and wastes. This kind of pollution is dangerous as it causes birth defects and death of organisms.
The problem with Justin's situation above is that, he used the oil and antifreeze DIRECTLY into the ground. Antifreeze is also known as an "engine coolant." This is a toxic chemical that should not be ingested. The frogs from the pond behind his house must have ingested the engine coolant, thus resulting to their deaths. It is said that animals are attracted to its smell, thus they are more prone to ingesting or drinking it.
If you are doing it on your own without going to the service station, it is best to bring the substance to the appropriate facility that disposes it. However, in case you spill it accidentally, you may pour some soap and water so it can be mixed together, thereby reducing its toxicity.
