Explain how dysfunction at one level of organization impacts other levels and provide an example.

Answers

Answer:

Please find the explanation below

Explanation:

All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.

Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).

How is cold front formation different from stationary front formation? Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass. Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses. Cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold air mass moves over a warm air mass. Stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when a warm air mass moves over a cold air mass.

d) temperatures of molten rock inside Earth

Answers

Answer:

C

Explanation:

Vibrations occurring inside Earth

The type of information that scientists collect using a seismograph is vibrations occurring inside Earth. The correct option is c.

What is seismograph?

A seismometer is a measuring device that detects ground noises and shaking caused by earthquakes, volcanic eruptions, and explosions.

Seismographs are typically made up of a seismograph, a timing device, and a recording device.

Seismographs are devices that record the movement of the ground during an earthquake. They are installed in the ground all over the world as part of a seismographic network.

To better understand seismic waves, scientists developed and used a device known as a seismometer. Seismometers now assist scientists in predicting earthquakes.

Scientists use seismographs to collect information about vibrations that occur within the Earth.

Thus, correct option is c.

2. Why must the satellite use electromagnetic
waves instead of sound waves?

Answers

Answer:

Since electromagnet waves do not need a medium they can travel through space. Sound waves can't travel through space because they need a medium.

Explanation:

The satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

What types of electromagnetic waves are used by Satellites?

The types of electromagnetic waves that are used by satellites are known as radio waves. These waves are utilized in order to carry out satellite signals with a speed of 3000,000km/sec.

Electromagnetic waves facilitate the required amount of speed and characteristics which ease the transmission of information required by the satellites. Radio waves are traveling through the vacuum of space with the fastest speed at which the information via the satellite can be transmitted. Radiowaves are also used for spacecraft communications as well.

Therefore, the satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

HELPP!! Describe how the enzyme transforms the substrate. Include in your answer the vocabulary terms: substrate, active site, enzyme, product(s).

Answers

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Which letter in the image above represents the activation energy of a reaction
WITHOUT an enzyme present?

C
B
A & B
A

Answers

Answer: B

Explanation: Because the Red shows activity

Activation energy is defined as the minimum amount of energy required for activating the atoms or molecules to undergo chemical transportation or transfer.

The correct answer is:

Option D. The letter A.

In the graph, activation energy can be explained as:

1. The activation energy is the minimal amount of energy necessary for the compounds to participate in the chemical reaction.

2. In the graph, the activation energy without the enzyme is represented by A,  the activation of energy with enzyme is represented by B, and the change in the free energy is represented by C.

Thus, the correct answer is Option D.

describe the arrangement of water molecules in a solid, liquid and gas form. how does the movement of the molecules differ in each form? Describe the bonds when the molecules are in motion.

Answers

Answer:

In a solid, the molecules are tightly packed in neat rows and they vibrate quickly. Solids have a definite shape and volume. In a liquid, the molecules have more energy and they move around more freely. Liquids have a definite volume but they don't have a definite shape. The molecules in gases are spread apart and move very freely with very much energy. Gases do not have a definite shape or volume.

Hope this helps!

:)

The description of the arrangement of water molecules and their motion in a solid, liquid and gas form and how they differ in each form is as follows:

Solid state is characterized because the molecules that compose it are very close together by a network of covalent bonds and in more or less fixed positions; this makes the distance between the particles practically unchanged.

This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.

In the liquid state, the forces between the particles are weaker than in the solid state, which allows the particles to have some freedom of rotation and translation, due to mobile ions.

Besides the vibration; they can slide over each other and maintain a constant mean distance between them without being fixed.

For this reason, liquids, unlike solids, take variable forms, depending on the container that contains them and they can also flow easily.

Their similarity to solids is based on the fact that, like the solids, they are difficult to compress and have constant volume.

In the gaseous state the attractive forces are practically zero and the particles acquire a total mobility of vibration, rotation and translation,

Being the distance between the molecules much greater than the one that they have in solid or liquid state and, in addition, variable at all times.

Gases, unlike solids and liquids, can be easily compressed or expanded and also take the shape of the container that contains them, occupying the entire available volume.

Therefore, the intensities of the interactions or cohesion forces of water molecules are not the same in solids, liquids and gases, the effects of movement and interaction on the arrangement of the particles are opposed, resulting in different states of aggregation.

A wildlife biologist and her team counted 150 lizards in a 25 km area. What is the population density

Answers

Given parameters:

Number of lizards  = 150 lizards

Area of the study = 25km²

Unknown:

Population density = ?

Solution:

Population density refers to the number of organisms per area in a particular location.

Mathematically;

     Population density  = [tex]\frac{Total Population}{Area}[/tex]  

    Population density  = [tex]\frac{150}{25}[/tex]   = 6lizards/km²

The population density of the study area is  6lizards/km²

The virus would have DNA. - Both bacteria and viruses have DNA (or the virus might have RNA)

The bacteria would make another person sick. - Both viruses and bacteria could make another person sick

The virus would have proteins - Both viruses and bacteria have proteins

9. If your cells were used to discover a cure for a disease do you think you should have first given consent for their use? Should you also receive something back if the research makes lots of money. Explain why.

Answers

Answer:

If my cells were used to discover a cure for a disease I don't think it would matter to give consent because I would have saved lots of people. I think I should earn just a little bit of money, because they are my cells, but I don't think I should earn a lot or most of it.

Answer:

Yes, you need to give consent because otherwise, they can not have any part of you without consent.

Explanation:

  You should expect some money even if it is a small amount to come to you due to you being the one with the cure therefor the scientist or bioglist would have to study them and would go on to trials if they make a vaccine. Always, give consent if you deem it the right choice never by force.

Why are most stray cats short hair cats, but a variety of colors?

Answers

According to the American Humane Society, roughly 95% of all cats are short hair cats (called domestic shorthair). This applies not just to strays but cats that have owners as well. So that fact alone is enough to be able to see why most strays are short hair cats.

Through my research, I'm reading that some people claim that long hair cats are more expensive and rare cats, so the owner is likely to take better care of them and keep them indoors. This further inflates the percentage of stray short hair cats out on the street. I couldn't find much about this from an official source, but instead just through forum posts.

As for the colors, I'm not entirely sure. The cat's fur color comes from its genetics. So it's possible that darker more earth-tone colors help the animal survive better compared to say a lighter color or white fur. Due to natural selection and survival of the fittest, the darker hair color cats will eventually out-number the lighter fur colors. That's my theory anyway. I couldn't find much data or studies to back that up.
