Which of the following neuronal pools leads to a long lasting output from a single input and so may be involved in higher order thinking? 1) parallel-after-discharge 2) converging 3) reverberating 4) diverging

Answers

Answer 1
Answer:

Answer:

1) parallel-after-discharge

Explanation:

Neural circuits are defined as the connections between neurons. These neural circuits are of four types:

  1. Diverging circuits, found in sensory and motor neurons, diverge a single nerve impulse to multiple neurons in the circuit, amplifying the original signal.
  2. Convergent circuits, also found in sensory and motor pathways, converge multiple nerve impulses into a single one. These pathways are predominantly involved in inhibition and stimulation.
  3. Reverberating circuits, involved in control of sleep-wake cycle and breathing, consist of a neuron chain along which the impulse travels.
  4. Parallel after discharge, involved in cognition and mental processing, are a combination of convergent and divergent circuits. They result in an output impulse that lasts at least 15 m/s after the input impulse ends.

What are the two types of behavioral adaptation

Answers

Answer:

The 2 types of behavioral adaptation are migration, and hibernation.

Explanation:

Adaptation of animal is the fitness towards its environment. If an animal can't adapt, it will perish with time. Adaptation may be genetic or acquired. But basically, adaptation is 2 types - physical adaptation, and behavioral adaptation.  

Physical adaptation includes the coloring of the body, camouflage activity of an organism. The behavioral adaptation is the respond of the organisms to their habitat. This includes hibernation, estivation, migration, etc.

Some animals are affected by the temperature difference of the environment. Therefore, they adopt some methods to survive in extreme temperatures.

The cold-blooded like amphibians hibernate during winter.  They undergo a long sleep during cold weather and become active in summer.  Similarly some animals like desert lizard active in the morning. When the temperature increase they burrow themselves under the ground. This is called estivation.

Birds migrate during the adverse season i.e. in winter. They temporarily go to a different place to spend the cold month and return during the advent of summer. This is one type of behavioral adaptation. They also migrate for better breeding ground and food.  

Some fishes also migrate for breeding and food.

All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.
Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.
Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.
Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.
The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

Answers

A Venus flytrap produces new leaves from the step tip. The life characteristic that this illustrates is A. Growth. Venus Flytraps are composed only of leaves, and rather than sharing a root system, each leaf grows its own root or roots, and each root is a single structure, not dividing or 

Transports materials within the cell

Answers

Transport materials within the cell are called Motor proteins.

Materials within a cell are primarily transported by motor proteins. These specialized proteins move along the cellular cytoskeleton, a network of protein filaments including microtubules and microfilaments, serving as tracks for intracellular transport.
Two prominent motor proteins involved in intracellular transport are dynein and kinesin.

Dynein typically moves cargo towards the minus end of microtubules, while kinesin moves it towards the plus end.

They carry various cellular components, such as organelles, vesicles, and proteins, to precise locations within the cell.
This intracellular transport is crucial for many cellular processes, including protein trafficking, organelle positioning, and cell division.

It ensures that the cell's components and materials are delivered to the right place at the right time, allowing for proper cell function and maintenance.

In summary, Motor proteins transport materials within the cell.

Radial symmetry
Bilateral symmetry
Asymmetry

Answers

The correct option is, B, that is, RADIAL SYMMETRY.
Symmetry refers to the balanced distribution of the duplicated body parts or shapes within the body of a living organism. There are different types of symmetry, we have bilateral, radial and asymmetrical symmetry. 
Radial symmetry refers to the type of body plan in which the body parts are arranged around a central axis, that is, the body parts are arranged in a circle around an axis.

Answer:B

Explanation:

The Answer is radial symmetry

Favorable traits are traits that promote an organism's success in a particular environment. Organisms with favorable traits are more likely to thrive, survive, and reproduce than organisms without favorable traits. Over time, favorable traits are likely to________ within a population and unfavorable traits are likely to ________ within a population.

Answers

Answer: Grow ; Disappear.

Explanation:

The organism that best suits in the environment is likely to grow and reproduce and its population in the environment increases.

Over the time the characters that are favored more survive and the characters that does not allows the organism to survive in harsh conditions are not favored.

These organism die and over the time the traits disappear from the population.
1. Evolve/Grow
2. Disappear

It's because they can survive and reproduce while the unfavorable die off and cannot reproduce, so their traits disappear from the gene pool.
