<u>Answer</u>:- Option B Brown
<u>Explanation</u>:-
- When the beetles are living in a vegetation, then the most important point is that they are living in an environment where <em>green is the predominant color.</em>
- Since, the birds who will come to look for food, will have to identify the beetles against a green backdrop the green beetles are <em>most</em> safe as they can easily merge with their green surroundings. This is known as camouflage.
- The mixed beetles will be less fit as compared to the green beetles as the chances of them to be identified by the birds will be more as they are not completely green and are not able to fully merge with the surroundings.
- However, the brown beetles will be <em>least</em> fit to survive in this environment as they can be most easily identified against the green backdrop. They will be the most conspicuous of the three beetles. Thus, the birds will feed more often on the brown beetles and hence, they are least fit to survive in the vegetation.
This phenomena in which the organism who is best adapted to survive in a given environment and leave more progeny is termed as <em>survival of the fittest.</em>
Answer:
Detail is given below.
Explanation:
First of all we will understand the pH.
pH:
pH is the negative log of hydrogen ion concentration.
pH = -[logH⁺]
It means when the ions concentration increases pH will be low and when H⁺ concentration ions decreases pH will be greater. The pH range is 0-14.
If the pH is 7 the solution is neutral, if it is less than 7 the solution will be acidic and above 7 the solution is basic.
when CO₂ is added with water carbonic acid is formed and yield H⁺ ions which decreases the pH thus its color changes from red to yellow just like phenolic indicator. When phenol red is added into the acidic solution the color changes from red to yellow.
and when carbon dioxide is take off from photosynthesis process it means H⁺ ions are going to be decreased thus color changes from yellow to red.
Answer:
A person who claimed to see a car of a certain make/model leaving the scene of a crime.
Explanation:
Key words to the answer:
"See"
"leaving the scene of a crime."
Eyewitnesses have a firsthand glimpse of events that occurred and they usually have to have seen something that has occurred to be considered a eyewitness, in this case the person who saw the Make/Model of the car that left the crime scene has some claims that can be used to find the criminal and also when the eye witness sees the car they can tell which direction it went in to give a bit of a clue(although this depends in certain situations). The eye witness can also be anyone who was anywhere near the crime scene when it happened or even a little bit after it happened.
Answer:
<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>
<u></u>
Explanation:
Neurons, specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.
Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:
- photoreceptors
- mechanoreceptors
- chemoreceptors
- thermoreceptors
Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.
