The right answers are: B. and C.

This measurement technique is based on Archimedes' principle :

Any body immersed in a fluid at rest, fully wetted by it or crossing its free surface, undergoes a vertical force, directed from below upwards and opposite to the weight of the fluid volume displaced; this force is called Archimedean thrust.

For the theorem to apply, the submerged fluid and the immersed body must be at rest. It must also be possible to replace the immersed body with submerged fluid without breaking the balance, the counterexample being the stopper of a bathtub filled with water: if it is replaced by water it is clear that the tub is empty and that the fluid is no longer at rest. The theorem does not apply since we are in a case where the cap is not completely wet by the liquid and does not cross its free surface.

The following statements are correct about the displacement method:
1. It can only be used to measure the volume of solids.
2. It may yield incorrect result if the matter is soluble in liquid.
The displacement method is usually used to measure the volume of solids, especially irregular solids. It involves dropping the solid in water and measuring the volume of water that is displaced. The result may be affected if the solid is soluble in water.

Which number identifies the system that serves as the site of nutrient and waste exchange between cells and the interstitial flu

Mrrafil [7]

The site for exchange nutrients and waste in capillaries.

Exchange of Gases, Nutrients, and Waste Between Blood and Tissue by diffusion Occurs in the Capillaries. Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.

Plasma and interstitial fluid are very similar because water, ions, and small solutes are continuously exchanged between them across the walls of capillaries, through pores and capillary clefts.

Capillary walls contain small pores that allow certain substances to pass into and out of the blood vessel.

Scientists have evidence that the Antarctic Bottom Water is becoming fresher and warmer. What are two changes that could happen

alexgriva [62]

This would be because of the melting of icebergs, ice is made of fresh water, that means the water increases in freshness because of the increasing amount of ice melting. It is getting warmer most likely because of global warming, which also contributes to the melting of glaciers

A woman expressing a dominant phenotype is heterozygous (dd) at the gene. part a what is the probability that the dominant allel

kap26 [50]

The woman have heterozygous (Dd) gene so she should have one dominant gene and one recessive gene. When her cells undergo meiosis, the gene would be split and the result of the child would be 50% cell with dominant gene and 50% cell with recessive gene.

Her child that have dominant gene will have 50% chance to inherit the dominant gene into the woman grandchildren. So, the total chance would be: 50% * 50%= 25%

Answer:

Oxygen Ion: -1 charge

Sulfur Ion: Neutral charge

Explanation:

Protons always have a + charge.

Electrons always have a - charge.

Oxygen:

If we have 8 protons and 9 electrons, we can see that we would only have +8 charge vs a -9 charge. Therefore:

8 - 9 = -1 charge overall

Sulfur:

If we have 16 protons and 17 electrons, we can see that we would have an overall charge of -1:

16 - 17 = -1 charge overall

However, since we lost an electron, we now only have 16 electrons:

16 - 16 = 0 charge, or neutral overall

Explain why global climate models typically work by treating the planet as a set of connected boxes

choli [55]

Answer:

Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.

Explanation:

Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.

The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:

Winds.
Temperature.
Relative humidity.
Rainfall.
Pressure changes.
Heat transfer.
Hydrological dynamics.

Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.

It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.
