best explanation of the role of dna and rna in making proteins?

Answer:

DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

What is protein synthesis?

Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously. The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription.

Initiation, elongation, and termination are its three stages.  Following processing, the mRNA transports the instructions to a ribosome in the cytoplasm.

The ribosome, which is made up of proteins and rRNA, is where translation happens. The mRNA's instructions are read during translation, and tRNA then transports the appropriate sequence of amino acids to the ribosome. rRNA then facilitates the formation of bonds between the amino acids, resulting in a polypeptide chain.

A polypeptide chain may be further processed to create the finished protein after it has been created.

Therefore, DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

In the area illustrated, what process is evident over time?

Answers

In the area illustrated in the image attached, the biological process which is evident over time is: ecological succession.

Ecology can be defined as the scientific study of the relationship existing between living organisms such as plants and animals with respect to their physical and biological environment (abiotic factor).

In Ecology, ecological succession refers to a process through which the structure of an ecological (biological) community evolves or changes over time.

Generally, there are three (3) main types of ecological succession and these include:

Primary successionSecondary successionCyclic succession

From the ecological (biological) community illustrated in the image attached, we can deduce that there is an evolution (change) in the species of plants growing over time. This ranges from weeds during the first visit to pine and oak trees during the seventh visit.

Dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.

The dominant trait is the one that is the first to appear or express itself visibly in the organism. Example: In human beings, we observe V-shaped hairline.

Dominant individuals are often most influential in their social groups, affecting movement, opinion, and performance across species and contexts.

Answers

kinetic energy is needed by the molecules in order to escape from the surface.

All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.

Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.

Answers

In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.

The percentage of energy transferred to the deer after feeding on the grass is 10%.

The 10% law of the energy states that:

1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.

2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.

Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.

The correct answer is Option C.

Answers

Answer: Crossing over

Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️

The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.

What is Crossing over?

Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.

Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.

Therefore, the correct option is B.
