Answer:B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.
Explanation: Eucaryotic cell is a cell whose Nucleus is clearly defined and confined within a membrane.
Procaryotic cell is a cell which does not have a clearly defined Nucleus.
Signals are stimuli which can be felt by an organism, specific organismal have its own kinds of signals which it can respond to,but some times signals with specific features can create response in two or more type or species of organisms. What happened in the lab is a case where a partial signal can be sensed by both procaryotes and eucaryotes because it has either a similar structure or its pathway can be used by either Eucaryotic cells and procaryotic cells.
1. an organism that doesn’t have a nucleus nor membrane bound organelles.
2. an organism that does have a nucleus and membrane bound organelles.
3. the similarities between prokaryotic and eukaryotic cells are the cell membrane, cytoplasm, and both contain DNA.
4. parts of a prokaryotic cell may include the plasma membrane, the cytoplasm, the DNA, and the ribosomes.
5. an example of prokaryotic are bacteria like E. Coil.
6. these are examples because E. Coil is a bacteria that doesn’t have membrane bound organelles.
Accuracy refers to how close a measurement is to the true value of what is being measured. Precision refers to how close measurements of the same quantity are to each other, even if they are not close to the true value.
so the answer is accurate
hope this helps
C. Saturn
A. Jupiter
F. Neptune
E. Uranus
Humans do have 5 sensory organs namely eyes ears nose tongue and skin. Each of them do have different stimuli to receive from environment.
<h3><u>Explanation:</u></h3>
Most of the sensory organs house in the head of human beings. Functions of each of them are discussed below:
A. The eyes house in the cranium orbit and are two in number which senses the visible spectrum of electromagnetic waves also called as light rays. The retina in the eyes sense it and sends the information via the optic nerve.
B. The ears house on lateral sides of head which sense the audible range sound waves. The organ of Corti senses the sound vibrations and sends them to brain via auditory nerve.
C. The nose house on the midline of head on the anterior surface which senses the smell and sends via nerves.
D. Tongue houses in the buccal cavity which senses the taste of food and sends via different nerves to brain.
E. Skin is located all over the body and it senses different stimuli like pressure, temperature, pain etc and sends to brain via different sensory nerves.
