Answer:
Generally, if a cell does not recognize something, it will launch an immune response.
Explanation:
This is why individuals who have organ transplants must be put on immunosuppressants, when cells do not recognize a foreign body they will immediately assume it is harmful and make an attempt to attack it.
Which of the stream types had a statistically lower macroscopic invertebrate species diversity than the seasonal streams?.
Intermittent streams have a statistically lower macroscopic invertebrate species diversity than the seasonal streams.
What are Intermittent streams?Intermittent streams are ecosystems where water flow is stopped at least twice in a given period of time.
Intermittent streams exhibit biodiversity that is different from other types of streams because species can not be adapted.
Intermittent streams are ecosystems that can exhibit specific species which are not found in seasonal streams.

Animals from colder climates generally have shorter limbs. This is called
(a) Allen’s rule
(b) Johnson’s rule
(c) Arber’s rule
(d) Niche rule
Answer:
(a) Allen's rule
Explanation:
It is a heat-conservation mechanism that prevents heat loss from the body. Heat gain and heat loss can be maximised and minimised by lowering the surface area to volume ratio of the body. Small animals are uncommon in the polar regions due to their larger surface area and lower volume.
I am joyous to assist you at any time.
Answer:

Are mirror neurons the scientific explanation for empathy?
Answer:
Mirror neurons respond both when perceiving an action and while executing an action. They provide a direct internal experience of another person's actions or emotions and may be the neurological basis of empathy.
Explanation:
Mirror neurons respond to perceiving an action while executing an action. They provide a direct internal experience of action or emotion of another person and are the neurological basis of empathy.
What are mirror neurons?Mirror neurons are a category of neurons that modulate activity both when an individual executes a specific motor act and also when they observe a similar act performed by another individual.
Mirror neurons activate when for example when monkeys break peanuts when they see others doing the same even in darkness as they hear peanuts being broken.
The mirror neurons are the scientific explanation for empathy.

Is the “extra finger” trait dominant or recessive? How do you know?
Answer:
It is recessive.
Explanation:
Having an extra finger, also known as polydactyly, is relatively rare, and people with polydactyly are unlikely to have children with the trait unless both the mother and father both have it, making it a recessive trait.
In a mass extinction, many species become extinct at the same time. scientists have concluded that a mass extinction killed the dinosaurs and other species, in part as a result of an asteroid striking the planet. what pattern in the fossil record supports this conclusion?
The pattern in the fossil record which supports the idea of a mass extinction event is the sharp decrease in biodiversity in rock layers.
What is a mass extinction event?A mass extinction event is one which in which a large number of species of organisms die off due to natural or artificial causes.
A mass extinction events is concluded to have killed the dinosaurs and other species, in part as a result of an asteroid striking the planet.
The evidence for this in fossils records is that the lower, older rock layers contains a great diversity of fossil life forms, while the younger layer immediately above is contains few organisms in comparison.

What are muscles?Muscles are a special type of tissue that has the ability to contract in response to a given stimulus.
There are different three types of muscle fibers: cardiac muscle, skeletal muscle and smooth muscle.
Cardiac muscle and smooth muscle are involuntary muscles, whereas skeletal muscle is a voluntary muscle.

https://brainly.com/question/1283837
Answer:
Involuntary: Smooth
Voluntary: Skeletal
Electrical Nodes: Cardiac
Tendons: Skeletal
Digestive Tract: Smooth
Arteries: Smooth
Extensors: Skeletal
Explanation:
Types of muscles. The three kinds of muscle in the body are the skeletal muscle, the smooth muscle, and the cardiac muscle. The skeletal muscles are attached to the bones and allow one to move at will. Because the skeletal muscles are mostly under your conscious control, they are sometimes called "voluntary" muscles. Smooth muscle lines the inside of such hollow organs as the digestive system, bladder, and arteries. Smooth muscles work automatically and are beyond your conscious control. They are referred to as "involuntary" muscles. Cardiac muscle is unique to the heart.
Although skeletal muscles seem to be under your control, a lot happens of which you are not aware. First of all, your posture, even when asleep, is controlled by skeletal muscles without your paying much attention to it. Your mouth, for instance, would flap open if your brain did not maintain a certain tension in your chewing muscles all the time. Your chin would spend a lot of time resting on your chest if your neck muscles didn't hold your head up. And your movements of all kinds would be pitifully awkward if your cerebellum did not coordinate all the muscles necessary to perform even the simplest actions. Just scratching your nose, for instance, requires dozens of muscles to move in exactly the right way at exactly the right time. You are truly "fearfully and wonderfully made."
We will now take a closer look at the other two types of muscles. Skeletal muscles can be attached to other muscles or to bones either directly or by a thin band of connective tissue called a tendon. Do not confuse this tendon with a ligament, which connects bone to bone and not muscle to bone. Two good examples of tendons can be found in the back of your legs. One is the Achilles tendon which attaches the calf muscle in the lower back part of your leg to your heel. The other tendons are on the back side of your knee, called the hamstrings. They serve to attach muscles in the upper back part of the leg to the bones of the lower leg and flex your knee. Locate these structures on your own leg.
The point at which a muscle is attached to the less movable part of the body is called the origin. The point at which a muscle is attached to the more movable part of the body is called the insertion. The biceps muscle of your upper arm is a good example of both these points. The biceps has its origin in your shoulder and its insertion in the bones of the forearm.
Skeletal muscles differ relative to their effect on the body. Those muscles that bend a joint are called flexors, and those muscles that straighten a joint are called extensors. Muscles always work in pairs, one opposing the action of the other. For instance, the upper arm has biceps on the front, which serves as the flexor. The muscle that opposes this motion and serves as the extensor of the forearm is the triceps, which is located on the back of the upper arm. When one muscle contracts, the other must relax. Study the diagram and then see if you can feel the alternating contraction of the biceps and triceps in your own upper arm as you bend and straighten it.
You should be careful to get enough exercise to keep your muscles in good shape. Muscles will grow larger and have better tone, which means they will always be slightly contracted, if they are used. If a person is lazy or is confined to a bed or wheelchair for a prolonged period of time, the muscles not being used will become smaller and lose their tone. This condition is called atrophy. A muscle atrophies at a rate of about 1% a day, so that it will lose a full third of its strength after a month of disuse. Disuse also causes bones to soften by losing their calcium. "Use it or lose it" is a solid maxim of physiology.

Define Photosynthesis.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Consider the cross aa bb cc dd ee x aa bb cc dd ee. If these 5 allele pairs all assort independently, then the probability that any individual offspring will have the genotype aa bb cc dd ee is 1 out of.
If the allele pairs assort independently, the probability that any individual offspring will have the genotype aabbccddee would be 100% or 1 out of 1.
Independent assortmentSince the alleles assort independently, the gametes from each genotype will all be abcde.
