<span>ecosystems
</span>An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>
Answer:
This is Because they can't be 100% in location of PCBs since animals could spread and reproduce among different places with these toxins within their systems.
Explanation:
DNA makes up genes. Transcription: The info stored in the gene's DNA is transcribed to RNA in the cell nucleus. The type of RNA that contains the info for making a protein is called messenger RNA, also known as mRNA. It carries out the information from the DNA, out of the nucleus, and into the cytoplasm. Translation: This happens in the cytoplasm. It is where the mRNA interacts with the ribosome, which "reads" the sequence of mRNA bases. Three bases make a <em>codon</em>, which usually codes for one particular amino acid, which is building blocks of proteins. Then, another type of RNA called transfer RNA, aka tRNA, assembles the protein by folding. This continues until the ribosome reaches a stop codon.
Answer:
- Earth's atmosphere has a mix of gases organic molecules could have been made from simple chemical reactions involving these gases. ... - Filled up the glass apparatus with water and gases which they thought made up the atmosphere. - Boiled the mixture and shine UV light on it, which mimicked sunlight.
<span>wind-driven and ocean-current circulations move warm water toward the poles and colder water toward the equator. The ocean can store much more heat than the land surfaces on the Earth. The majority of the thermal energy at the Earth’s surface is stored in the ocean. Thus, the absorption and movement of energy on the Earth is related to the ocean-atmosphere system.
El Nino and La Nina- La Nina is known for its unusually cold temperatures in the Equatoral Pacific. E</span><span>l Niño, is characterized by unusually warm ocean temperatures in the same region
