Water in the blood helps carry nutrients and gases required foe survival througout the body. Which characteristics of water allow for this action?

A.water has a neutral pH
B.water maintains temperature
C.what expands when it freezes
D.water dissolves many compounds

Answers

Answer:

Water has a neutral pH

Explanation:

None of the others exactly fit in with what this is saying, and water having a neutral pH allows the supplies and nutrients that it carries to stay safe within it throughout the way.

Sorry if this isn't correct or full-fledged explained like I normally do, I saw you said to hurry up and I didn't do my normal research and whatnot.

Anyways, hope this helped!

Sources: N/A

The characteristic of water that allows this process of carrying nutrients and gases is water has a neutral pH. Thus, the correct option for this question is A.

What are the characteristics of water?

The characteristics of water are as follows:

It is a universal solvent. Due to the partial positive charge on hydrogen and partial negative charge on oxygen, it is a polar molecule. It has high heat capacity and high heat of vaporization. It has properties like cohesion and adhesion. Its solid form is less dense as compared to liquid.

Due to having the property of neutral pH, water significantly performs movement across the entire body with the help of blood.

It does not form any barrier with the differences in the level of pH. So, along with blood, water carries nutrients and gases that must be required for proper survival throughout the body.

Therefore, water that has a neutral pH is the characteristic property that allows the carrying of nutrients and gases required for survival throughout the body.

Explanation:

The organelle that is responsible for transporting lipids in the cell is Golgi apparatus. The correct option is A.

What is Golgi apparatus?

A Golgi body, also renowned as a Golgi apparatus, is a cell organelle that aids in the processing along with packaging of proteins as well as lipid molecules, mainly proteins destined for cell export.

The Golgi body is a series of stacked membranes which is basically named after, Camillo Golgi the one who discovered it.

The Golgi apparatus transports, modifies, along with packaging proteins as well as lipids into vesicles for delivery to specific destinations.

The Golgi apparatus is a crucial organelle for cargo post-translational modification.

Golgi-resident enzymes including glycosyltransferases, glycosidases, and kinases mediate post-translational modification of secreted and membrane proteins.

Which theory best describes this?

Answers

Answer:

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates).  Bacteria do not grow and multiply the same way as animals or humans. They take in nutrients and reproduce by dividing – one bacteria splits and becomes two bacteria, two become four, four become eight and so on.

Lodgepole pine trees produce seeds in cones. The cones open after being exposed to high temperatures created by wildfires. How does this adaptation help the lodgepole pine survive?

A) It allows the lodgepole pine tree to make more seeds in cones that are hard to open.
B) It creates more wildfires for the lodgepole pine tree to reproduce.
C) It makes the seeds travel and grow in areas where there are no wildfires.
D) It helps the lodgepole pine tree to protect the seeds and to reproduce.

Answers

Answer:

D

Explanation:

A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.

Answer:

D

A It allows the lodgepole pine tree to make more seeds in cones that are hard to open. IS WRONG B) It creates more wildfires for the lodgepole pine tree to reproduce.

Explain why flask #2 (yeast with glucose) produced more CO2 than flask #5 (yeast with flour). AND how did you know it produced more CO2?

Answers

Answer: Glucose

Explanation:

The carbon dioxide produced in the experiment can be directly related to the energy generated after the fermentation process. The carbon dioxide is the byproduct of the chemical reactions in the ethanolic fermentation. Glucose substrate will yield the highest energy along with the highest producer of the carbon dioxide after the fermentation process conducted by yeast as compared to the fermentation process that was conducted by yeast with flour. The flour will offer a source of carbohydrates including starch and sugars. The yeast will find out sugar in the flour and ferment it. Glucose is readily available sugar for the action of yeast so more production of carbon dioxide is expected from glucose substrate.

Which statement best describes the movement of ocean waves? Water moves across the ocean's surface water remains in the same place as wave (energy) travels through it water moves because there is a difference in density of the water creating a wave none of these

Answers

Answer:

water remains in the same place as wave (energy) travels through it

Explanation:

Winds influence the ocean and its movements. Air current running on the ocean surface transfers energy to water. A wave is nothing else than energy. When the winds provide energy to the water surface and produce waves, it occurs a particular water molecules´ motion. They move in circles from up to down, up to a certain depth, and go back to the surface. And they do so while energy from the wave is passing through. Waves are the ones that move through the ocean until they reach the shore, where the energy is transferred to land. Water molecules remain in the same general area, while energy travels from molecule to molecule as a wave.

What is food energy?

Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

To find the total calories, multiply the given biomolecules grams with their calorie count.

= 42 × 4 + 7 × 9 + 34 × 4

= 168 + 63 + 136

= 367 calories

Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?

Answers

Answer:The two processes are CONDUCTION and CONVECTION

Explanation:

The Energy produced in the Earth core is generated by  Sun, gravitational force , radioactive decay, and the  Earth' rotation, To maintain balance in the earth, The  processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of  tectonic plates at a  constant rate.

Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous  transfer of heat energy  from the warmer mantle at  the bottom   to  the cooler  mantle  at the top While Convection currents in the core move thermal energy causing  the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and  creating a balance in the earth.
