The type of receptor that activated by intense stimuli of any type that results in tissue damage is chemoreceptors (A).
What are the 5 types of sensory receptors?Receptor is a protein that can bind to a small molecule to receive a message from other cells. Sensory receptors are categorized into five types according to their sensitivities, are, chemoreceptors, pain receptors, thermoreceptors, mechanoreceptors, and photoreceptors.The intensity of the sensory input to the brain is referred to as stimulus intensity. A stimulus has a threshold, or the minimum degree of intensity required for detection and action. For example, there is a minimum threshold for being able to hear something. If it is too quiet, you would not realize that the stimulus is there.Learn more about chemoreceptors here: brainly.com/question/29737864

Explain how a population of antibiotic-resistant bacteria might develop from non-resistant
bacteria. Do you think that farmers should be allowed to put low doses of antibiotics in
animal feed? Explain the reasons for your answer.
Answers
Answer:
More exposure causes mutation in bacteria.
Explanation:
More exposure to the antibiotic by non-resistant bacteria causes change in its structure against the environment and as a result of that change the bacteria get resistance against that antibiotic. No, farmers should not be allowed to put low doses of antibiotics in animal feed because it has no effect on the antibiotic-resistant bacteria. The farmer should use another antibiotic on the antibiotic-resistant bacteria which they have no resistance.
Genes that are located near each other on the same chromosome are called:A. incompletely dominant.B. codominant.C. linked.D. multiple alleles.
Answers
Incompletely dominance is a form of inheritance in which one allele is not completely expressed in a specific trait because of this pattern of inheritance with its paired allele. So, the explanation doesn't fit and A is incorrect.
Codominanceis a oform of inheritance in which both alleles are expressed, even if they are different, so both traits will appear. So, the explanation doesn't fit and B is incorrect too.
Multiple allele refers t when a population has more than two alleles o f the same gene. So, the explanation doesn't fit and D is incorrect too.
Genetic linkage occurs when two genes are lcated close to each othwer in a chromosome and are often inherited together, and that fits the definition that was given. Therefore, the correct answer is C. linked.

Someone makes a loud noise and it scares you use complete sentences to put the following vocabulary terms in order to describe how the body processes the sound and reacts central nervous system, sensory organs, and sensory receptors
Answers
Answer:
When someone makes a loud noise and it scares you, your body goes through a series of processes to respond to the sound. I'll break it down using the terms you mentioned.
Explanation:
Sensory organs: These are specialized parts of your body that detect stimuli from the environment. In the case of hearing a loud noise, your ears are the sensory organs responsible for detecting sound waves.
Sensory receptors: These are specialized cells within your sensory organs that convert the stimuli, in this case, sound waves, into electrical signals that can be understood by your body. In your ears, tiny hair cells act as sensory receptors, converting the sound waves into electrical signals.
Central nervous system: This refers to your brain and spinal cord, which are the main components of your central nervous system. Once the sensory receptors in your ears convert the sound waves into electrical signals, these signals travel through nerves to reach your central nervous system.
So, in the situation where someone makes a loud noise, the sound waves are detected by the sensory organs (your ears), which then send the information to the sensory receptors (hair cells). The sensory receptors convert the sound waves into electrical signals, which are then transmitted through nerves to your central nervous system (brain and spinal cord).
Once the electrical signals reach your central nervous system, your brain processes the information and determines that the loud noise is something to be concerned about. It may trigger a response, such as a startled reaction or the feeling of fear. These responses are coordinated by your central nervous system, which sends signals to various parts of your body to react accordingly.
So, the order of the processes involved in how the body processes the sound and reacts to a loud noise is: sensory organs (ears) -> sensory receptors (hair cells) -> central nervous system (brain and spinal cord).

Answers
D. mass and strength. Early gliders were mostly built of wood, with metal stays, fasteners, control cables. For strength, lightness, later wings made of wood, fabric were coupled with steel tubes in fabric as fuselage.
Since then, performance has been improved by using new materials including carbon fibre, fibre glass, and Kevlar. Due to its strong strength to weight ratio and capacity to provide a smooth outside surface to reduce drag, this material is still utilised today. Improved aerodynamics and retractable undercarriages have also reduced drag. Some gliders have wings with flaps attached to the trailing edges to maximise lift and drag at a variety of speeds. The performance of gliders has been better with each new generation of materials and with advances in aerodynamics.

Food chain for an ocean ecosystem:
1) Algae (producer/photoautotroph)
2) Zooplankton (herbivore)
3) Squid (1st level carnivore)
4) Salmon (2nd level carnivore)
5) Sea lion (apex predator)
Being a producer, algae uses the energy from the sun's photosynthesis to create its own nourishment. Zooplankton consumes the algae in the estuary because they are herbivores. As first-level carnivores, squid consumes zooplankton. Salmon consume squid because it is a second-level carnivore. The top predators in this food chain are sea lions, who eat salmon.
What is an Ecosystem?A complex network of living and nonliving creatures that interact with one another in a particular environment is called an ecosystem. It is a self-sustaining system in which all living things and the environment in which they live work together to maintain equilibrium. The size of an ecosystem might vary from a tiny pond to a massive forest or ocean. An ecosystem's living creatures are all interdependent on one another in order to survive, and they all contribute significantly to keeping the system's delicate balance.
All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements.

Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."
