Which of these describes the life history of a species with a fast, intensive reproductive investment? Please choose the correct
raketka [301]

Humans produce few offspring throughout multiple reproductive episodes.

Explanation:

According to the prediction of Life history theory that organisms are capable to increase their fitness who is either by producing many offspring or by producing fewer and also high-quality offspring. Offspring investment is extended by human but some it is obscured by their cultural mechanism.  

In human species the quality and quantity doubt has been empirically shown in the species which produce litters or clutches, where their litter size is large which leads the small offspring size and their growth rate became slow and due to this their survival is getting reduced.

The Comparative analyses also help a negative and the inter-specific relationship between their reproductive rate and their offspring size

List the four types of neural circuits and describe their similarities and differences. Discuss the unity of form and function i
NNADVOKAT [17]

Answer:

There are four kinds of neural circuits. Functions of each is given underneath:

* Diverging circuit :- In this circuit, one neuron synapsis with various post synaptic cell. What's more, every one of this may neurotransmitter with a lot more and making it workable for one neuron to stimulate numerous cells, approx thounsands of cells. Each time the main neuron fires, the other neuron which is down the succession fires it in reverse to impart back the sign to the source.  

* Converging circuit :- The contributions from numerous sources are joined into one output. This prompts affecting a neuron or a neuron pool. This sort of circuit is exemplified in the respiratory focus of the brain stem. This gives a reaction to various contributions from various sources by giving out a suitable breathing pattern.  

* Reverberating circuit :- It is a neural circuit where nerve impulses that were activated because of stimuli are reactivated so that retreival of data is conceivable on schedule.  

* Parallel after release circuit :- A neuron contributions to a few chain of neuron. Each tie is comprised of various number of neurons. Be that as it may, their signs spread into one output neuron. Despite the fact that the info has been halted the output will go one terminating signals for quite a while.  

similarities of the neural circuits :-  

* All the neurons collaborate with every neuron cell whether it would be input sources or output.  

* They on the whole play out all the activities in the neural system.  

For contrasts, you can allude the elements of the four unique kinds of neural circuits. I referenced the capacities such that you can comprehend their disparities moreover.  

All things considered, in the event that these neurons don't work together, at that point its unthinkable for the body parts to work. What's more, despite the fact that all the neurons funtions appropriately yet on the off chance that one neuron doesn't work appropriately, at that point some body parts won't have the option to react.  

The neurons are associated with a sequential structure with the impulse that the sign goes in succession. So one sort of neuron is associated with the other. So even one neuron is evacuated or harmed then its exceptionally difficult to play out the elements of the body. Since the chain would be broken and the impulse gets halted toward the finish of the last neuron.

Vijay really enjoys eating ice cream. the joy he receives from eating it comes from the dopamine reward center in which area of
alisha [4.7K]

The pleasure and the reward centers of the brain are control by the neurotransmitter known as dopamine. Besides this, the emotional responses and the movements of a person are also controlled by dopamine.

The reward response from eating ice cream is related to the nucleus accumbens  part of the brain. The nucleus accumbens is a part of the basal forebrain, present in each of the brain hemispheres. The dopamine neurons in the VTA (Ventral tegmental area) are activated when the activity such as eating ice cream occurs. These neurons are projected into the nucleus accumbens, and their activation gives a feeling of pleasure.

Hence, the answer is 'nucleus accumbens'.

Plant cells contain chlorophyll to turn light energy into chemical energy. Chlorophyll, in plant cells, is stored in an organell
Tcecarenko [31]

Answer:

Chloroplasts are organelles found in the broccoli's cells, along with those of other plants and algae. They capture light energy and store it as fuel molecules in the plant's tissues. Mitochondria are found inside of your cells, along with the cells of plants
