The genetic information in human and chimpanzee DNA shows a high degree of similarity, as humans share about 96-99% of their DNA code with chimpanzees. What is an explanation for this similarity?

Answers

Answer 1
Answer:

This similarity can be explained by Charles Darwin's Theory of Evolution. Humans and chimpanzees share a common ancestor wherein a number of million years ago, due to adaptation of their environment, human species branched out and eventually evolved into Homo sapiens. 

Answer 2
Answer:

Answer:

The correct answer would be common ancestry.

Common ancestry means that different species have been established from a single parent species or population.

Organisms which share more recent common ancestors tend to have more similarity as compared to the organisms which share an older ancestor.

Humans and chimpanzees also believed to evolved from a common ancestor around 6-7 million years ago.

It is the reason why humans and chimpanzees share around 96-99 percent of the DNA.

Which occurs during translation? A.mRNA is created by using a DNA template. B.mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein. C.Protein is formed when a polypeptide chain is broken apart and released from ribosome. D.One strand of DNA is copied into a strand of rRNA.

Answers

The answer is B.mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein. According to the central dogma of molecular biology, DNA sequence specifies RNA sequence which specifies protein sequence. DNA sequence is first copied into mRNA sequence during transcription. Later, during translation, mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein

Final answer:

During translation, mRNA codons are joined by tRNA anticodons to assemble amino acids into a protein. The other options refer to other processes in protein synthesis or distort what happens.

Explanation:

During translation, which is a step in protein synthesis, option B: mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein, correctly describes the process. In the ribosome, the tRNA anticodon base pairs with the mRNA codon, which each specify a particular amino acid. These amino acids are then linked together to form a polypeptide chain, which folds into a protein. Option A refers to transcription, option C is a distortion of what happens during peptide release, and option D refers to rRNA formation, not translation.

Which explanation is most likely an effect of the evolution of a larger brain in humans? A larger brain allowed humans to use tools. A larger brain allowed humans to solve complex problems. A larger brain allowed humans to better survive disease. A larger brain increased humans' ability to fight.

Answers

Answer:

The correct answer is the option: A larger brain allowed humans to solve complex problems.

Explanation:

Hello! Let's solve this!

Evolution shows that characteristics have developed over time that have allowed living things to survive in the environment.

In this case, it involves the size of the brain. The brain grew so that the human being could solve more complex problems.

We conclude that the correct answer is the option: A larger brain allowed humans to solve complex problems.

Answer:

A larger brain allowed humans to solve complex problems.

In order to stimulate an effector in a toe, which pathway does a nerve impulse follow after it is initiated at a receptor?A. sensory neuron -> interneuron -> motor neuron
B. motor neuron -> interneuron -> sensory neuron
C. interneuron -> sensory neuron -> motor neuron
D. None of these

Answers

Answer:sensory nuerone to internuerone to motor neurones

Explanation:

The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.

These receptors send signals as action potential to the spinal cord to the brain.(CNS).

Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.

The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.

The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction
