Describe the genetic code and its relationship to polypeptides and proteins
The genetic code is directly related to polypeptides and proteins in the sense that genes are decoded to synthesize proteins.
What is the genetic code?Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.
The genetic code is unique for living organisms and is used to synthesize the proteins that is responsible for various activities in living organisms.
The genes in the genetic code are first transcribed into mRNA, which is then translated into proteins (polypeptides).

The most common use of radioactive isotopes in medicine is to diagnose disease. Typically, radioactive materials are injected into the body and then radiation-detecting cameras are used to build images of affected body parts or particular types of cells. This equation models the amount of a radioactive isotope in the bloodstream minutes after it is injected:
Radioactive substances are employed in therapy to destroy malignant tissue, shrink a tumor, or lessen discomfort.
What is the radioactive elements?Two or more chemical species of an element with varying atomic masses and unstable nuclei are referred to as radioactive isotopes. Because of the excess radiation that these isotopes produce in the form of alpha, beta, and gamma rays.
Nuclear medicine treatments use a tiny amount of radioactive substance called a radiopharmaceutical to assist diagnose and cure disorders. To identify disorders, some radiopharmaceuticals are utilized in conjunction with imaging technology. To reduce or eliminate a cancerous tumor, radiopharmaceuticals can also be injected close to the tumor inside the body.

observations
Umak
C. only non-numerical observation from an
experiment
Answer:
B
Explanation:
The definition for 'Data' is facts and statistics collected together for reference or analysis.
So I would answer B as this seems the most appropriate
The data is the detailed recordings of experimental observations. The correct option is B.
What is experimental observations?Because of the physical insight they provide to the scientist in formulating the theory, experimental observations and measurements are widely accepted to be the backbone of physical sciences and engineering.
Observational studies are those in which researchers examine the impact of a risk factor, diagnostic test, treatment, or other intervention without attempting to change who is or is not exposed to it.
Observational studies are classified into two types: cohort studies and case control studies.
Experiments or surveys are used to collect data for statistical studies. The branch of statistics that deals with the design and analysis of experiments is known as experimental design.
Thus, the correct option is B.

Answer:trait encoding for short plant structure to reduce transport of water
Explanation:The Sahara Desert is a zone which receives very low or no precipitation. This region receives maximum of sunlight not received by any other biome. The soil is typically sand which is highly porous and lacks essential growth nutrients necessary for plant growth. The plants grown around Sahara Desert are xerophytic plants. These plants undergoes several adaptations in order to prevent loss of water through transpiration. Trait encoding for short plant structure to reduce transport of water is a xerophytic adaptation.

They include EPSPs and IPSPsThey are changes in the membrane potential of the postsynaptic terminal of a chemical synapseThey are caused by neurotransmitters. Thus, the correct option is B, C, D.What is postsynaptic stimulation?An additional neuron known as a fascilitator is triggered when the postsynaptic neuron receives an unconditioned stimulation. The presynaptic neuron then responds to this cell, leading to sensitization.
When the neurotransmitter separates from its receptor, postsynaptic potentials start to be terminated. After that, the receptor is free to resume its original structural form. The receptor will now reopen ion channels that were opened when the neurotransmitter was attached to it.
