6. Which marrow was denser (had more mass in the given volume)? What impact would that have on the overall density of the bone?

Answers

Answer:

The beef bone marrow was denser than the chicken bone because it had more mass in the given volume. Since the chicken must fly, it cannot have its bones weighing it down on the land. However, cows must find grass on land and travel long distances. This would increase the overall density of the bone.

describe how energy for the photosynthesis reaction is gained by plants (2)

please help ​

Answers

Answer:

Plzzzz answer fast......

The energy for the photosynthesis reaction is gained in the first stage of the reaction.

There are 2 stages in photosynthesis:

The light-dependent stageThe light-independent stage

During the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.

The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.

The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.

Answers

Answer:

The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.

Explanation:

Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria

If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.

When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

what would happen to the ecosystem in the terrarium if it were a closed system for energy

Answers

Answer:

It would mimic the behavior of the earth's atmospheric atmosphere where you have a water cycle and sunlight which aids photosynthesis.

Explanation:

A terrarium is a glass container that can be covered and opened at will. It can be used to grow a plants using soil.

When it is sealed, water evaporates onto the body of the glass and runs down the sides of the glass only to be evaporated again and the same process happens over and over again.

Because the plants are in a glass container, they can still access sunlight for photosynthesis.

Sometimes the glass is opened up for maintenance. Maintenance here refers to the removal of algae that sometimes forms on the inner walls of the terrarium. Sometimes, there is also need to add water to the ecosystem in the terrarium given that the water inside usually escapes via evaporation over time.

Explanation:

What do you think would happen to the population of rabbits, if the population of foxes decreased?

Answers

Answer:

the population of rabbits might increase

Explanation:

With less predators to eat them, the rabbit population will likely go up if the fox population decreases; assuming there are favorable factors such as plenty of food and habitat for the rabbits. At some point, there is a maximum limit to the number of rabbits that a certain location can hold. Once this limit is reached, (some of) the rabbits will migrate elsewhere or unfortunately die off.

As the rabbit population increases, the fox population may rebound and start increasing again. This is due to more food being available to the smaller amount of foxes, and there is less competition for food. So the rebounding fox population will likely bring down the rabbit population to a point where food will get more scarce for the foxes. This cycle repeats itself where one population increases while the other decreases, and vice versa. They are very strongly linked together. It's also possible that both will increase together if environmental factors are favorable, but they could easily decrease together if a habitat is being destroyed for instance. It will depend on the circumstance.

What is Infrared radiation?

All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.

This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out

Answers

Answer:

air is drawn into the lungs

lungs expand

the muscles between the ribs contract to move the ribs up and down

air pressure in the chest cavity decreases

the diaphragm contracts and flattens

Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.

What is inhalation?

Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.

This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.

Therefore, the air is drawn inside the lungs in inhalation.

How does the aorta compare in size to the other blood vessels near it?

Answers

Answer: Its wider and thicker than most blood vessels

Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.

Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

It has 24 pairs and 48 number of chromosomes.

Explanation:

The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.
