explain how the difference in diameter is responsible for the process that occurs in the malpighian body

Answers

Answer:

Explanation:

Malpighian body is made up of the glomerulus and the Bowman's Capsule. The glomerulus is a network of capillaries that receives blood from the afferent arteriole and gives it further to the efferent arteriole. From the glomerulus, the component of blood diffuse into the Bowman's Capsule through the endothelium and basement membrane of the glomerulus and the epithelium of Bowman's Capsule.

The blood comes into the glomerulus through which it is diffused into the Bowman's capsule. Only the smaller solute molecules and water is allowed to pass through the membranes while the blood cells are retained within the glomerulus. Hence, the Malpighian Body allows the filtration of blood so that the waste can be separated from the blood. The filtrate further moves to tubules where fine reabsorption and secretion takes place. Both the kidneys produce approximately 180 liters of filtrate every day.

The difference in diameter is responsible for the process that occurs in the malpighian body as - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.

Malpighian Body is a structure located in Nephron in the urinary system that helps in ultrafiltration of blood. It consists of a glomerulus and its surrounding Bowman's capsule.

There are two main arteries in the Malpighian body of blood vessels

one entered for filtration, called afferent arteriole.one leaving the structure after filtration called efferent arteriole.Differences in diameter provide for the increased blood pressure in the glomerulus for ultrafiltration.The afferent arteriole has a larger diameter, which leads to more blood would flow into the efferent arteriole, which is of a smaller diameter due to this causes more blood pressure or hydrostatic pressure in the glomerulus.

Thus, the correct answer is - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?

A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.

Answers

Answer:

Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.

Explanation:

Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The  spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone. The most significant result of water distortion is on groundwater.

B) two more clectrons than carbon-12.
C) two more neutrons than carbon-12.
D) A and C only
E) B and C only

Answers

Answer:

C

Explanation:

this is because that Carbon 12 has 6 protons and electrons and the same goes for Carbon 14 so Choice A and choice B can't be answers so D and E arent equivalent too that means Choice C can be the appropriate answer.

further more explanation:

it's also Choice C because both carbon atoms are neutral which means that the number of protons and the number of electrons are the same so that leaves us with neutron and we get the neutron number by subtracting the mass number with the proton number so let's go on shall we!

for carbon 12= 12-6=6

for for carbon 14=14-6=8 which means the best alternative is Choice C.

Best of luck!!!

essay on atoms molecules and matter

Answers

Answer:

Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.

H20 is a molecule, N2 is a molecule even O3 is a molecule.

Matter is basically anything that takes up space and that has mass. All physical objects have matter. The original stated of matter are solid, Liquid, And gas.

Three major types of variables observed such as An independent variable which is a singular characteristic, Age is an example; A dependent variable which can be influence by the effect of other variable.

A dependable variable can be changed by independent variable, For example a grade on an exam is a dependent variable type mainly depend on Independent variables.

Control variable referred as the variable which remain constant and no effect on other variables but it is used to prevent bias in an experiment and provide accuracy of the result.

Timber is the one that describes the ecosystem services. The correct option is 2.

What is ecosystem services?

Many of the basic offerings that people rely on are provided by ecosystems. Plants purify the air and water, bacteria biodegrade waste, bees pollinate flowers, and tree roots keep soil in place to safeguard against erosion.

These are fairly simple to identify. Food, water, timber, fibers, and even medicine are among them. Other naturalistic explanations and materials are controlled by regulating services.

Goods such as food and water are illustrations of ecosystem services, as are the regulation of floods, soil erosion, and disease outbreaks, as well as non-material benefits such as recreational and religious benefits in natural areas.

Thus, the correct option is 2.
