What is the most important organism on the food web?
Provide a link to a resource if can.
Short answer: To lower the price of oil and reduce dependence on foreign imports, a federal government is debating whether to open large stretches of its coastline to domestic drilling. Evaluate this plan in terms of two ecosystem services that the country might gain and two services the country might lose if the coastline is opened for drilling. In your answer, be sure to explain how a perceived negative externality might become an internal cost.
Answer:
This drilling enhances economy of the country but at the same time disturbs aquatic animals.
Explanation:
Due to drilling at coastline, oil should be extracted from the sea which fulfills the oil requirement of the country and valuable money can earned by exporting this oil. Due to this drilling, the habitat of aquatic animals are destroyed and no trade should be done from this coastline with other countries because the area is now only for drilling. So this plans has both positive effect on the country's economy but has negative impacts on the environment and ecosystem.

Tonya's father does not have the dominant trait of webbed feet, and neither does Tonya's mother. What is the percentage that Tonya or any of
her brothers of sisters will have webbed feet?
Answer:
0%
Explanation:
For Tonya or her siblings to inherit one of their parents must have that allele. Since both her parents have the recessive phenotype that means neither of her parents carry the dominant gene so it would be impossible for Tonya or her siblings to have webbed feet.

Where could the instructions be held to create a protein?
Answer:
The correct answer is - in DNA molecules.
Explanation:
The instructions or the information for the creation of the protein is held in the DNA molecule inside the nucleus in eukaryotic organisms while present in the cytoplasm in prokaryotes.
The DNA molecule has coded all the information for the particular protein by the two processes transcription and translation. Transcription is the first step which makes a copy of the DNA is complementary in the form of mRNA, The second step involves the decoding mRNA into an amino acid chain with the help of ribosomes.

How have trees adapted to survive through the cold winter months?
Answer:
Adaption
Explanation:
Adaptations. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold.

Which of the following is true regarding the large intestine?
А
It is the major site of water absorption.
B
It is four times as long as the small intestine.
Most chemical digestion occurs there.
D
It contains salivary glands, which secrete amylase.
The statement that is true regarding LARGE INTESTINE is option A which states that It is the major site of water absorption.
The LARGE INTESTINE is part of the alimentary canal in the digestive system of mammals. The main function of
• Is to absorb water and salts from the material that has not been digested as food, and
• get rid of any waste products left over.
The main parts of the LARGE INTESTINE includes:
• the cecum,
• the colon, and
• the rectum
From the cecum, the undigested food passes into the colon. Here, WATER is ABSORBED. This concentrates the waste products and makes them semi-solid. In this state, the waste products are called faeces. Faeces pass into the rectum and out of the body through the anus.
Therefore the statement that is true regarding LARGE INTESTINE is that It is the major site of water absorption.

What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.

She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)

Ears back or flatten against head
Pupils dilated
