true because it means the formation of a new plant or animal species
Which option describes the function of RNA polymerase?
Select one:
Carrying amino acids to the transcription site.
Moving mRNA strands into and out of the nucleus.
Splitting the DNA double strand into two single strands.
Forming an RNA strand using a DNA strand as a template.
Answer:
brown
Explanation:
have you pooped today?
The option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.
What is RNA polymerase?RNA polymerase may be defined as a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. This enzyme is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.
RNA polymerase binds to DNA, separates the strands, then uses one of the strands as a template from which to assemble nucleotides into a complementary RNA strand.
It uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
Therefore, the option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.

How can we tell that two species shared a common ancestor, and are therefore related?
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules
Explanation:
There are multiple ways you can tell
you can look at the bone structure of an organism and see if it's homolougous
Or use a cladogram to tell what species share a common ancestor ( hope this helps)
When a squirrel hears a strange noise that might indicate the presence of a predator, fight-or-flight hormones are released into its system. The hormones help prepare the squirrel's body to do strenuous physical activities, like quickly climbing up a tree, more efficiently. Which statement describes how two organ systems work together to help a squirrel respond to a possible external threat?
Answer:
The flight-or-flight hormones are released by the endocrine system in response to environmental changes detected by the nervous system.

Pitfall traps (pitcher plants) trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria. Flypaper traps use a sticky mucilage. Snap traps utilise rapid leaf movements. Bladder traps suck in prey with a bladder that generates an internal vacuum.
Answer:
They use special traps that are connected to them.
Explanation:
For example, the Venus Flytrap uses it's "mouth" to close on the fly. A sundew plant uses sticky spines to stuck to the bugs and slowly curls up and digests the bug.

Answer:
before the common ancestor of all extant life.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
The current genetic code evolved before the common ancestor of all extant life i.e that are still in existence or alive.
