Explain Give two examples of how abiotic factors are influenced by biotic factors?
Answer: If this doesn't help just let me know
The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controlling the biotic factors of an environment.
The interaction between humans and water and plants and soil are examples of the influence of biotic factors on abiotic ones.
Biotic and abiotic factors are biological terms to refer to:
Abiotic factors: are the set of non-living physical and chemical components of an ecosystem.Biotic factors: are the set of living components of an ecosystem.According to the above, living beings (biotic factors) can affect abiotic factors such as water because they contaminate it with chemicals or waste.
Also, plants (biotic factors) see the soil (abiotic factors) because they provide them with nutrients.

A sample of an unknown liquid has a volume of 24.0 mL and a mass of 6 g. What is its density?
Answer:
0.25 g/cm³ or 0.25 g/mL
Explanation:
Density = Mass / Volume, so you would then plug in your two variables.
D = 6 g/ 24 mL = 0.25 g/mL or 0.25 g/cm³
Answer:
15.607 lbs or 250 g/L
Explanation:
Density is calculated by dividing the mass (6 g.) by the volume (24 mL). With that knowledge you come to the answer which is 250 g/L which is the measurement I'm assuming you'd need considering you're dealing with a liquid.
If you need a different measurement of density, let me know.

Para a ocorrência de osmose, é necessário que (analise as afirmações a seguir e marque como resposta a soma dos itens corretos usando os números entre parênteses):
(04) as concentrações de soluto dentro e fora da célula sejam iguais
(08) as concentrações de soluto dentro e fora da célula sejam diferentes
(16) haja energia na célula para que o transporte de água ocorra
(32) haja lipídios atravessando a barreira
(64) haja parede celular para o rompimento da célula
Answer:
(08) and (32)
Explanation:
To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.
The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.

________________ are substances that break lipids (fats) into very small globules so that they are more manageable in watery fluids
Answer:
Emulsifier
Explanation:
Emulsifier are the chemical additives which are required to breaking up fats or lipids globules into much smaller emulsion droplets.
An emulsifier consist of one oil-friendly and one water-friendly end. When an emulsifier added with fat or lipid, the emulsifier face towards the oil/water or air/water interface reduces the surface tension to make emulsion more stable.
Emulsification of fat makes the food easy to absorbed by small intestine.
Hence, the correct answer is "Emulsifier ".

Identify ways in which all biological systems from cells and organisms to populations, communities and ecosystems are affected by complex biotic and abiotic interactions involving exchange of matter and free energy
Answer:
Explanation:
Cell which is the basic unit of life is affected by the interactions with biotic and abiotic factors such as temperature, sunlight. Organisms are made up of cells and they respond differently to temperature changes, sunlight, water availability. Some cell perform better at some certain range of temperature while some cannot.
Organism itself are affected by the interaction of some of this factors this include water and nutrients availability. Distribution of organism in a particular habitat is greatly influenced by availability of water and nutrients it lead to competition for survival among organism. Population density and species diversity also influence community and ecosystem. Population determines how resources is allocated in a community and it affect the activities of the organism in that domain or territory.
PLEASE HELP ITS DUE IN 30 minutes!!! which two statements explain why a student standing at the top of a step stool doesnt move downwards
Answer:
b. The step stool exerts a force on the student in the opposite direction of gravity.
c. A student exerts an upward force on the step stool equal to the gravitational force
Explanation:
It is true that gravity is the force that pulls the objects down to the earth but there are some forces that oppose the statement.
In the given situation, the student is unable to fall down from step stool is because of two forces one, the force exetred by step stool on student and two, the force exerted by the student on step stool.
The step stool exerts a force on the student in the opposite direction of gravity that gives stability to the step stool and an upward force on the step stool equal to the gravitational force helps the student to climb the stool.
Hence, the correct option are b and c.
what is the relationship between surface tension and cohesion
Answer:
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface.
The relationship between surface tension and cohesion is that Cohesion is directly proportional to surface tension.
What are surface tension and cohesion?Cohesion is the attraction of same molecules and surface tension occurs due to the attraction of molecules .
Therefore as the cohesion becomes high, surface tension becomes here.
We can say that the Cohesion is directly proportional to surface tension.
means As cohesion increases, surface tension increases.
Hence, the relationship between surface tension and cohesion is that Cohesion is directly proportional to surface tension.

The atmosphere is defined as an area consisting of air and various gases covering the whole mass of our environment.
Decomposers increase the fertility of the soil by converting organic substrate into an inorganic form. This gives a required condition to plants for their proper development. Water makes soil moisturized, ideal conditions for decomposers to play their own functional role. In this way, all the above factors are dependent on one another and make up the earth, from its core to its atmosphere.
Therefore, above are the five broad categories of materials described briefly.

The water vascular system of echinoderms _____. The water vascular system of echinoderms _____. is analogous to the gastrovascular cavity of flatworms moves water through the animal's body during suspension feeding functions in locomotion and feeding functions as a circulatory system that distributes nutrients to body cells is bilateral in organization, even though the adult animal is not bilaterally symmetrical
Answer:
The water vascular system of echinoderms functions in locomotion and feeding.
Explanation:
Echinoderms have a unique vascular aquatic system called the ambulacral system.
The ambulacral system refers to a net of fluid-filled channels derived from the coelom with functions related to gas exchange, feeding, stimuli reception, and locomotion. This system acts as a hydro motor apparatus.
The opening to the exterior of this vascular system is through an opening known as madreporite. This structure is united to the circular channel that surrounds the animal´s mouth and from where five radial channels emerge and extend along each arm. Water runs through these structures and makes it possible the gas exchange, feeding, locomotion, and other functions. By hydrostatic pressure, little tubular feet are protruded and retracted and help the animal to move.
