What activity is accomplished using the genetic code?cells make proteins.
RNA molecules are copied before mitosis begins.
mRNA molecules are transcribed to form tRNA.
polypeptides are made into mRNA.

Answers

Answer 1

Answer: (A) Cells make proteins
Proteins are composed of amino acids. Proteins are made in a process called translation, in which the cell commands.
(B) RNA molecules copied before mitosis begins
DNA molecules are copied before mitosis, not RNA.
(C) mRNA molecules are transcribed to form tRNA
DNA is used as template to form both mRNA and tRNA in a process called transcription.
(D) polypeptides are made into mRNA
mRNA is the template used to make polypeptides in a process called translation.

Therefore, A is the right answer.

Binomial nomenclature uses _____ words. Spanish Latin English French

Answers

Binomial Nomenclature uses Latin words. That way they can be understood from all nations and people that speak different languages.

Final answer:

The binomial nomenclature system used in biology for the scientific naming of organisms uses two Latin words to designate each individual species. The first word represents the genus, and the second word, the species.

Explanation:

Binomial nomenclature, which is used in biology for the scientific naming of organisms, uses two Latin words. These words are formed from Latin or Greek roots, regardless of the language spoken by the scientist.

The first word represents the genus, and the second word, the species. For example, the human species is scientifically named Homo sapiens, where 'Homo' is the genus, and 'sapiens' is the species.

Which process do scientists think provided earth with an oxygen-rich atmosphere?A. spontaneous generation

B. radiometric dating

C. photosynthesis

D. respiration

Answers

Photosynthesis provided the Earth with an oxygen-rich atmosphere.

Does Earth have an oxygen-rich atmosphere?

Earth's surface environments are highlyoxygenated from the atmosphere to the deepest reaches of the oceans, representing a hallmark of an active photosynthetic biosphere. However, the fundamental timescale of the oxygen-rich atmosphere on Earth remains uncertain, particularly for the distant future.

What provides the most oxygen on Earth?

Scientists estimate that 50-80% of the oxygenproduction on Earth comes from the ocean. The majority of this production is from oceanic plankton drifting plants, algae, and some bacteria that can photosynthesize

What enzyme connects the new nucleotides together and proofreads them

Answers

The enzyme that connects new nucleotides together during DNA replication is called DNA polymerase.

What is DNA polymerase?

DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.

It catalyzes the formation of phosphodiester bonds between the nucleotides, thereby linking them together and forming a continuous DNA molecule.

DNA polymerase also has a proofreading function known as 3' to 5' exonuclease activity. As it adds nucleotides to the growing DNA strand, it can detect and correct errors in base pairing.

If it identifies a mismatched nucleotide, it removes it through the exonuclease activity and replaces it with the correct nucleotide, ensuring high fidelity in DNA replication.

If a person is having a problem with balance, what part of the brain would most likely be the cause?

Answers

I reckon it's the cerebellum.

Which of the following is correctly paired with its function?Sensory somatic nervous system—controls skeletal muscles
Autonomic nervous system—creates voluntary response to stimuli
Parasympathetic nervous system—controls body response to emergency
Sympathetic nervous system—brings body to homeostasis
I know that C and D are mixed up definitions. The sympathetic nervous system controls the response to emergency situations and the parasympathetic brings the body back to homeostasis.
I'm also pretty sure the autonomic nervous system controls involuntary responses, not voluntary.

Answers

Answer:

The correct answer would be Sensory somatic nervous system—controls skeletal muscles.

Somatic nervous system is a part of peripheral nervous system which controls the movement of skeletal muscles or voluntary movements.

It connects the skeletal system with central nervous system.

It comprises of two types of nerves:

Afferent nerves: These are also termed as sensory nerves and carry stimulus from receptors to the central nervous system.
Efferent nerves: These are also known as motor nerves and they carry commands or response from the central nervous system to the effector organs. It leads to the contraction of the muscle and thus results in voluntary movement.

The below flow chart would help you better in understanding the classification of nervous system.
