Answer:
A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Trophic Levels
Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).

Explanation:
warm ocean currents cool as they flow along a coastline away from the equator. Explain what is transported and how.
Answer:
Both energy and matter are transported by ocean currents. In the case of the warm ocean currents that become cool as it flows along a coastal area, the transfer of energy is due to the movement of matter. The winds are responsible for moving the ocean currents. As the wind moves, the current absorbs the energy. In turn, the movement of energy or air from different places affects weather and climate conditions.SC4: I can explain how the following are

The interior membrane surface area of mitochondria is greatly increased by structures called _______.
Answer:
The inner membrane is usually highly convoluted, forming a series of infoldings, known as cristae, that project into the matrix. These convolutions greatly increase the area of the inner membrane, so that in a liver cell, for example, it constitutes about one-third of the total cell membrane.

A group of 7th grade science students have been asked to create a dichotomous key that can be used to identify the plants shown in the diagram below. Which of the following specifications should not be used when making this dichotomous key?
1.Circular shaped leaves --- Irregular shaped leaves
2.Leaves found in deciduous forest --- Leaves found in tropical forest
3.Leaves symmetrical on stem --- Leaves asymmetrical on stem
4.Leaves bunched on stem --- Single leaf on stem
The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.
What is a dichotomous key?A dichotomous key is a methodology employed by taxonomists to identify organisms from different taxonomic groups.
The dichotomous keys are always funded on phenotypic traits.
Dichotomous keys can be considered as two different options to identify a given feature of an organism.

2) If the amino acid sequences in homologous proteins of two organisms are similar,
what can you conclude about the DNA of the two organisms? You must use the terms
transcription and translation in your completed answer.
Answer:
If the amino acid sequence of two organisms are similar, then the organisms’ DNA sequences would also be similar. The central dogma of biology states that DNA contains the key for RNA, which then codes for proteins. Transcription and translation are the two phases of protein synthesis. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation. Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. In the cell cytoplasm, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein.

6. Applying Ideas: Suppose someone dumped left over motor oil on a driveway. Could this disposal
method contaminate the air, water, or soil? Explain
Answer:
If they are looking for one BEST answer, it is the water.
If looking for top two, it is water and soil.
Realistically, however, this disposal can contaminate all 3.
Let me explain:
The motor oil that is dumped on a driveway first makes its way into the soil. The freshwater found in this soil becomes contaminated with motor oil and can eventually runoff into the ocean. Once this liquid evaporates, it then becomes air pollution. Shortest, best answer tho is water.

The long nerve that is the major route for information travelling between the brain and many visceral organs is the _______ nerve.
The vagus nerve is the longest of all the cranial nerves and is responsible for transmitting information related to sensory and muscular activity, as well as anatomical functions.
What is vagus nerve?It is the major route with motor and sensory functions, which belongs to the classification of cranial nerves, and according to the anatomy and its place of exit in the cranial cavity, it is called the tenth cranial nerve.
Characteristics of the vagus nerveIt is not only responsible for innervating the face and head, but rather it follows a different route when it reaches the trunk area, specifically the organs of the abdomen, chest and neck.Its importance is evident in the digestive system, since it coordinates the movements of the esophagus, the visceral organs and the intestine.Therefore, we can conclude that the vagus nerve is the longest cranial nerve and has many branches, in order to reach the thoracic and abdominal cavities.
