Food Availability, Places to live, and water availability are all ______ of an Ecosystem.

Answers

Answer:biotic factors

Explanation:

They are living

Food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

What are Abiotic and Biotic components?

Biotic and abiotic factors make up ecosystems in which biotic factors are living things within an ecosystem such as plants, animals and bacteria, while abiotic are non-living components such as water, soil and atmosphere.

An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, the abiotic factors are temperature, light, and water. In a marine ecosystem, the abiotic factors are salinity and ocean currents. Abiotic and biotic factors work together to form a unique ecosystem.

Biotic components are living things that have a direct or indirect effect on other organisms in the environment such as animals, and microorganisms and their waste materials.

Thus, food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Why organisms are made up of cells?

These organelles are liable for an assortment of cell capacities, for example, acquiring supplements, creating energy, and making proteins. Unicellular living beings are comprised of just a single cell that completes each of the capacities required by the organic entity, while multicellular creatures utilize various cells to work.

Start with evaporation. Place a full cup of water in front of a sunny window. Use a marker to make a line at the beginning water level.

After evaporation we have condensation. When the water vapor reaches the sky it cools to form clouds.

Finally, a precipitation experiment. Again, fill a cup almost full with water.

Explanation:

Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.

In 1953, Watson and Crick discovered the structure of DNA by examining data from many different experiments. How did using Chargaff’s data help Watson and Crick determine the structure of DNA ?

Answers

Answer: Chargaff's observation was an important clue to the A-T and G-C pairings that Watson and Crick eventually proposed. ... The structure of DNA suggested that the order of bases contains information. Because A is always paired with T and G with C, the order of bases on one strand determines the order on the other strand.

Explanation:

Chargaff’s data helped Watson and Crick determine the structure of DNA

through determining that it has a double helical structure.

Chargaff's rule states that a DNA consists of nitrogenous base pairs in which

the pairs have equal units and specific binding mate.

Adenine binds with Thymine Cytosine binds with Guanine.

The base pairs present in the DNA makes its shape to be double helical.
