The question is incomplete as it does not have the option which are:

A) There are 20,000 genes.

B) Each gene codes for one protein.

C) Any other regions are "junk" DNA.

D) There are also genes for RNAs other than mRNA.

E) The species is highly evolved.

Answer:

D) There are also genes for RNAs other than mRNA.

Explanation:

The protein-coding sequence refers to the sequence which can code for a protein and is therefore also known as the coding sequence.

The coding sequence codes for the protein by producing a messenger molecule which caries the message or codes for the protein called mRNA.

But the cell also requires other types of RNA like tRNA or rRNA which are sloe encoded on the genetic material.

In the given question, since the genome contains the 20,000 protein-coding region which codes for protein shows that it also contain the coded information not for only proteins but for molecules other than protein like RNAs.

Thus, the selected option is the correct answer.

Answer:

Trophic level

Consumer

Producer

Explanation:

All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.

A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.

Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.

In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.

The graph below shows the radioactive decay of a material whose half life is 25 years.

yawa3891 [41]

The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. <span>40 seconds therefore, is your answer.</span>

When an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called.

Mashcka [7]

When an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.

<h3>What is an allosteric enzyme?</h3>

Allosteric enzymes are catalysts that exhibit a site for binding that is distinct from the active site.

Allosteric enzymes are controlled by many effector compounds that can bind to different sites.

The active site of the enzyme is the molecular domain of this protein where reactants can bind during a chemical reaction.

The heterotropic effects occur when the ligands of allosteric modulators (effectors) are linked to the enzyme.

An allosteric modulator is a molecule that binds to the enzyme in a site different to the active site and this binding alters its tridimensional conformation, thereby activating it or deactivating it.

In conclusion, when an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
