Answer: Precapillary Sphincters
Explanation: Capillary beds have precapillary sphincters at the junction of capillaries and the met arteriole. Constriction of these sphincters reduces the blood flow through their respective capillaries. When this occurs, blood is diverted to tissue or organs elsewhere.
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.
Hope this helps. Have a great day!

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.

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.

What is the biome represented in the climatogram? Multiple choice.
Answer:
B
Explanation:
Hello!
Let's define each choice and see what choice fits the criteria the most.
Temperate grasslands are open grassy areas with some population of trees, usually having around 500-900mm of rainfall every year.
Tropical rainforests usually do not have a dry season and rain all year round; it has around 1,800 to 2,500 mm of rainfall.
Tropical deserts don't have much cloud cover, hence why they won't get much rainfall. They're irregular and might only get around 250mm of rainfall per year.
Knowing this information, we can also see on the graph that there had been approximately 2100mm of rainfall this year, which helps us conclude that tropical rainforests are the correct answer with the rainfall range.

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.

Which type of active transport protein uses one protein to pump two different molecules?.
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.A volcanic eruption changes the environment and separates a population of foxes.
