What is an ecosystem?An ecosystem is defined as a system which comprises of all living organisms and physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other for requirement of energy.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

If bacteria do not contain a nucleus will bacteria still have DNA?
Of course not the DNA is found in two basic forms: a chromosomal loop and ring-like plasmids. The chromosomal loop is literally a looping string of DNA. Since there is no true nucleus in a prokaryotic cell, the DNA is suspended in cytoplasm, or the fluid filling the cell.

Thought and memory pass across synapses in the brain. What are the neural circuits transmitted by new or reactivated pathways called
Answer:
Neuronal networks
Explanation:
Neuronal networks are made of neurones that give the ability of understanding relationship in a set of data. It functions in similar way to brain function.
Neuronal networks are able to adapt to changes in input and give appropriate output.
A simple example of neuronal network is a system made up of neurones at input layer, hidden layer, and output layer.
Self learning occurs in this network as it can use past experience to better respond to a given stimulus

Explanation:
The majority of pesticides do not have a residual effect (i.e., not persistent; lose chemical activity) in the soil.
a) True
b) False
Answer:
B- False
Explanation:
Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Soil can be degraded and the community of organisms living in the soil can be damaged by the misuse or over use of pesticides. Some pesticides are more toxic to soil organisms than others.

why is it important to understand plant physiology in crop/plant production and productivity?in your discussion make sure that you mention related fields/areas in agriculture which specifically require a background of plant physiology
Knowledge of Seed physiology helps in understanding of different physiological and morphological changes that occur during germination. By knowing the different inputs requirement of plants (water, nutrients, sunlight) we can easily manage the plant population to get highest yield.

how do you find per capita growth rate over a month?
All you have to do is take the CGR (capita growth rate) percentage you just found and divide it by the number of years, months, etc. The complete formula for annual per capita growth rate is: ((G / N) * 100) / t, where t is the number of years.
Why must a forensic anthropologist be able to distinguish between antemortem and perimortem pathology
Answer: Antemortem describes injuries or pathologies inflicted on the victim before the death. Perimortem refers to any injury associated with the manner of death.
Explanation:
A foresen anthropologist is a person who is dedicated to identifying and studying skeletonized human remains and trying to determine markings on the bones that can elucidate the causes of death. In this way, the anthropologist seeks to learn about the events that occurred by studying the injuries and analyzing evidence left at the scene.
The term antemortem is used to describe injuries or pathologies on the victim before his or her death, which, however, have not caused the person's death. On the other hand, the term perimortem refers to injuries or pathologies associated with the manner of death. That is, it is necessary to distinguish between the two to determine the cause of death of the person. Not only has an antemortem injury or pathology not led to death, but it has no relationship to the event. And a perimortem injury or pathology is fatal, it must be focused on in order to clarify the facts and know how the person died.
Confusing an antemortem pathology with a perimortem one or vice versa, can lead to an erroneous diagnosis of the cause of death.

How do you know if something is alive? Describe some of the characteristics of living things.
Answer:
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
Answer:
To be alive organisms have to include all of the following:
- Made up of a cell or cells
- Has DNA
- Can reproduce
- Responds to the environment
- Grows and develops
- Exchanges energy
- Evolves
Explanation:
Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.

Which structures are highlighted? Which structures are highlighted? goblet cells submucosa chondrocytes in lacunae seromucous glands
The image is not given in the question, so the appropriate image is attached below:
Answer:
goblet cells
Explanation:
Goblet cells are the mucin-secreting glands found within epithelia. Their shape and size look like a goblet, hence named goblet cells, and contain narrow bases and wide apex.
The structure highlighted in goblet cells scattered within epithelia. Goblet cells function for producing mucin, create a protective mucus layer and immunoregulation.
Hence, the correct answer is "goblet cells".

Einstein's theory of general relativity was published in 1916. It became fully
accepted by scientists in the 1960s and is currently the best explanation of
gravity. Why did it take so long to become an accepted scientific theory?
A. The scientific community requires a certain amount of time before
a theory can be accepted.
B. Einstein's theory was difficult for many people to understand.
C. More evidence needed to be gathered to validate the ideas in the
theory
D. No scientific laws could be found to validate the theory.
SUBMIT
Answer:
B. Einstein's theory was difficult for many people to understand.
Explanation:
Einstein’s theory of general Relativity was largely Ignored for three decades because scientists at the time thought the theory was too complex compared to Newton's.
Therefore, it took long before the general science community accepted Einstein's theory of general relativity because Einstein's theory was difficult for many people to understand.
"B. Einstein's theory was difficult for many people to understand."
D. More evidence needed to be gathered to validate the ideas in the theory.
1.Gravity is
found only between the earth and the moon
not found in space, but is only found on earth
a pulling force that exists between all objects in the universe
a force that pushes objects away
2.Which statement is true about a planet’s orbital motion?
Orbital motion results when the object’s forward motion is balanced by a second object’s gravitational pull.
Orbital motion is limited to the moons of the planets and the planets in our solar system.
Orbital motion cannot be achieved with man-made objects.
Orbital motion only occurs when forward motion exceeds the gravitational pull.
3.How does distance affect the gravitational force?
The gravitational force decreases as distance increases.
The gravitational force is not changed by distance.
The gravitational force changes unpredictably with distance.
The gravitational force increases as distance increases.
4.As mass increases, the gravitational force
changes unpredictably
decreases
stays the same
increases
Answer:
The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.
