How can this be the case? A. Sharks store enough urea in their bloodstream to match the total solute concentration of the surrounding seawater. B. Sharks are osmoregulators. C. Sharks maintain high levels of sodium chloride in their skin. D. Sharks drink large volumes of seawater to compensate for the low salt concentration of their body fluids. E. None of the answer options is correct.

The diagram shows the same type of molecules in area A and area B.

With the passage of time, some molecules move from area A to area B. This movement is the result ot the process of

1. phagocytosis
2. pinocytosis
3. diffusion
4. cyclosis​

Answers

Answer:

3. diffusion, because molecules are moving from a high concentration(A) to a low concentration(B)

Diffusion is the net flow of matter from a location of high concentration to a region of low concentration as a result of the random mobility of molecules. Both stopping and reversing this process are not possible. Thus, option C is correct.

What are the main mechanism in diffusion process?

The molecules' kinetic energy causes random motion, which causes diffusion. This mechanism happens in simple diffusion without the help of a carrier protein.

The molecules travel from an area of high concentration to an area of low concentration due to their random mobility.

Chemicals flow across the plasma membrane from areas of high concentration to areas of low concentration in cells to maintain an equilibrium (balance) of internal substances.

This implies that if there are more items inside the cell than outside, they will go outside and vice versa. It happens when the medium around the cell contains more water than the cell itself.

Therefore, This movement is the result of the process of diffusion.

What are Tectonic Plates made of and what do they do?

Answers

Answer:

They move

Explanation:

Answer:

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.

3) identify and describe three abiotic characteristics of ecosystems. Give an example of how each

characteristic could be affected by a human activity

Answers

Answer:

The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.

Explanation:

In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.

Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.

--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.

--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.

--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.

Due to independent assortment and crossing-over, the possible allelic combinations found in gametes by the meiotic division of this cell are B and D can be on one chromosome, while b and d can be on the other. Therefore, the correct answer is (B) BD, bD, Bd, and bd.

What is crossing-over?

Crossing-over is a process that occurs during meiosis, the cell division process that produces gametes (sperm and egg cells) in sexually reproducing organisms. During crossing-over, homologous chromosomes exchange genetic material, resulting in the creation of new combinations of alleles.

What is the law of independent assortment?

The law of independent assortment is a fundamental principle in genetics that describes how different genes are inherited independently. Gregor Mendel first proposed this principle.

When you work in a School Lunch program, you’re bound to face challenges that pop up seemingly out of nowhere. That’s just the nature of serving hundreds or even thousands of students each day.

But, when you keep encountering the same Child Nutrition program problems, over and over, day after day, it’s likely more than just a coincidence.

Instead, there probably are bigger issues causing these problems.

The bad news is that it often can be unclear what these bigger issues are, which makes fixing them almost impossible.

The good news? We at Harris School Nutrition Solutions have spent thirty years working with the men and women of Child Nutrition programs all across the U.S., helping to diagnose and solve their School Lunch problems.

So, we figured we’d share with you some of the common school lunch-line challenges we’ve seen over the years, the real issues behind those challenges, and of course the solutions to both.

The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO​2​ and water. Like oil spills cause damage

to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.
