Answer: The spicules of the sponges are made up of calcium carbonate and silica. These structures are present in the body of sponges to provide them support and protection.
The sponges have the endoskeleton in the body which is developed by the specialized cells of the body.
The endoskeleton of the sponges are known as spicules. Actually the outer body of the sponges are very soft and internally has endoskeleton for protection which is a bit hard as it is made of silicon dioxide or calcium carbonate.
How would driving from Boston (near sea level) to summit of Mt. Washington affect the rate of oxygen exchange in your lungs? Explain in 1-2 sentences plz
Answer:
The rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington
Explanation:
At near sea level, Boston, where there is sufficient dense air and plentiful supply of oxygen, the rate of breathing and oxygen exchange in the lungs is at normal levels
At the height of 6,288.2 feet, which is the height of the summit of Mt Washington, the lung does more work to extract the oxygen from the air present which is less dense and contains less oxygen than the air at sea level such that a larger volume of air is required to supply the amount of oxygen the body requires
Therefore, the rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington.
Which statement best describes how deep-sea producers differ from other producers?

Which statement gives one reason that watershed protection programs are needed in Virginia
Ecosystems need to be controlled
Foods must be prevented
Dams can be damaged and may require repair
Wildlife can ruin water source when building habitats
Answer:
Dams can be damaged and may require repair
Explanation:
This is imperative to provide needed supports and maintenance for the aging dams,with capacity of up to 11,000. This dams were created as far back as 1948.Therefore the programme was geared towards effective re-habitation for maximum efficiency.
This repair programmes was termed Dam Rehabilitation Programme.And the secretary of Agriculture was given the authority to ensure effective execution of the programme.
In the state of Virginia,a total of 150 dams were part of the government landscape through the rehabilitation programme, and 11 of these have been well studied. .Todd Lake,Robinson Hallow, Lake Barton are some of these examples.

What is the term for the breakdown of glucose in the presence of oxygen? cellular respiration photosynthesis anaerobic fermentation
Answer:
Cellular respiration
Explanation:
Cellular respiration involves the breakdown of glucose using oxygen to produce energy, or ATP, that is used by the cell.
The breakdown of glucose in the presence of oxygen is called as cellular respiration.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Moreover, it is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Hence, it is a series of chemical reactions that break down glucose to produce ATP.

Which biomolecule do you think is most important in your diet? Why did you pick that biomolecule? Which biomolecule do you think is most important in cell function? Nutrition and snack foods A. List your three favorite snack foods. B Collect a nutrition label from each food. C. If any of the foods on your list don’t come in a package, you can look up the nutrition information on the Internet. D. Write a paragraph about each food. Is it a good source of carbohydrates, lipids, and protein? Would you consider this food healthy? Why or why not? 2. You may have heard the saying, “You are what you eat.” to explain what this statement means.
Answer/Explanation:
There is no single biomolecule that is most important in one's diet; however, proteins would be a fitting choice. This is because there are certain amino acids -- 9 in fact -- that our bodies cannot naturally produce and of which proteins consist. We need these amino acids to survive because they make up proteins, and proteins perform pretty much every crucial function you can think of, ranging from defense to cell signaling to structure. All biomolecules are important in cell function -- carbs are needed for your cells to burn for energy via cellular respiration (a process that yields app. 28-32 ATPs per cycle), lipids are needed for cell membranes (amongst numerous other needs), proteins are needed for the reasons above, and nucleic acids are needed for RNA and DNA.
A. Welch's, Oreos, Chips Ahoy
B. You should be able to do this.
C. Proves my point in B.
D. Yeah, generally the snacks I chose are not healthy, even Welch's fruit snacks. It's junk food and not high in protein. "You are what you eat" makes sense in the quite literal sense because your body mass, your health, and your overall physical attributes are determined by your diet, on top of exercise and your activities throughout your life.

A microscopic image of Arachnoidiscus ehrenbergi. Photo by Gordon T. Taylor, courtesy of the NOAA Which level of organization is seen in both Arachnoidiscus ehrenbergi and the human stomach? cell tissue organ organ system Mark this and return
The correct answer is the cell.
Since Arachnoidiscus ehrenbergi is a single cell organism the only level its of organization is cell. Human stomach is composed of many different types of cells which combine together in order to perform complex functions. Those cells are arranged in tissues which make an organ-stomach.
hope it helps!
The level of organization displayed by both Arachnoidiscus ehrenbergi and the human stomach would be the cell.
Since it has already been established that Arachnoidiscus ehrenbergi is a single-celled organism, it can only exhibit a cellular level of organization.
The human stomach, in a similar vein, is made up of different cells. One group of such cells are secretory epithelial cells. They include the mucous cells, parietal cells, chief cells, and so on.
Thus, Arachnoidiscus ehrenbergi and the human stomach have the capacity to exhibit a cellular level of organization.

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins? osmosis passive transport active transport diffusion
Answer: Active Transport
Explanation: Active transport is the movement of a substance (proteins, enzymes, etc.) from one area of the cell membrane to the next during diffusion, so this would most be affected due to the kinds of substances being transported across the cell membrane and damage can have an impact.
Carrier proteins are involved in active transport. The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.
What are the carrier proteins?Carrier proteins are transmembrane molecules involved in active transport.
They carry molecules from one side of the membrane to the other side.
What is active transport?Active transport acts against the electrochemical gradient, so it does need the energy to transport substances.
It carries molecules from a low concentration side to a high concentration side.
The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.
