Why do Eukaryotes all use cellular respiration?

Based on the principle of bioaccumulation. the amount of pesticide each snake will take in compared to each grasshopper is 100x

Assuming that the grasshoppers eat only grass, the mice eat only grasshoppers, and the snakes eat only mice, the amount of pesticide each animal takes in will depend on their position in the food chain and how much pesticide is present in the environment.

Based on the principle of bioaccumulation, the amount of pesticide each snake will take in compared to each grasshopper is calculated as follows;

Let the grasshopper take in x amount of insecticide

Amount taken by each snake = 10 * 10 * x

Amount taken by each snake = 100x

The rectilinear mapping method uses one object as an anchor for all measurements.

What is rectilinear mapping method?

Rectilinear mapping is a type of crime scene mapping method that involves creating a scaled diagram of the scene using a series of straight lines to connect measured points. This method is useful in indoor crime scenes and is often used to create a two-dimensional representation of the scene. The key feature of rectilinear mapping is that it uses a grid system, which helps ensure accuracy in measuring distances and angles. The grid system allows for the creation of a precise and detailed map of the crime scene, which can be used to analyze evidence and reconstruct events.

What are the indoor crime ?

Indoor crimes refer to criminal activities that take place within a building or enclosed space. Examples of indoor crimes include burglary, robbery, theft, assault, homicide, and domestic violence. These types of crimes often occur in residential, commercial, or public buildings such as houses, offices, schools, and hospitals. Indoor crime scenes may require different types of investigation techniques and evidence collection methods compared to outdoor crime scenes due to factors such as limited space, the presence of multiple rooms or levels, and potential contamination from human activity.

Answer: non dysfunction

Explanation:

Answer:

The complete steps are:

1. Body needs energy for activity

2. body releases epinephrine

3. epinephrine binds to fat cells in adipose tissue

4. triacylglycerols (triglycerides) are hydrolyzed to glycerol and fatty acids

5. Fatty acids transported to tissue

Explanation:

Mobilization of fat is a gluconeogenetic process (a process that sequesters energy from a compound other than carbohydrates), in which fat molecules in the adipose tissues are metabolized for energy production.

The process starts when the body is in an energy-deprived (hypoglycemic) state, leading to the release of glucagon by the pancreas and the release of epinephrine (adrenaline) from the adrenal medulla of the brain.

These hormones activate gluconeogenesis and glycogenolysis (breakdown of glycogen) in the liver, it also activates lipolysis in the muscle cells and liver, as well as inhibiting fatty acid synthesis. This is mediated through the binding of these hormones to specific receptors on the surface of fat cells, leading to the activation of lipases (enzymes catalyzing lipolysis). Lipases catalyze the hydrolysis of triglycerides (common fat in diets) to glycerol and three molecules of free fatty acids. These free fatty acids are released into the blood where they attach to serum albumin; a protein for transporting the hydrophobic fatty acids to the muscle cells where they are taken up and utilized to produce energy and C0₂.

Motion energy refers to the energy related to an object's movement. When an object is in motion, it possesses kinetic energy, which is a form of motion energy.

The matching will be:

motion energy = energy related to an object's movement

chemical energy = stored energy related to positions of atoms within molecules

thermal energy = energy of motion of particles in a substance

nuclear energy = energy released when a nucleus splits or combines

gravitational potential energy = energy related to height

sound energy = energy generated by vibration of a string

Chemical energy is stored energy that is related to the positions of atoms within molecules. It is the energy that can be released or absorbed during a chemical reaction. When chemical bonds are formed or broken, energy is either released (exothermic reaction) or absorbed (endothermic reaction) in the process.

1. The graph below depicts the frequency of expression of the coloration of beetles on an island:

Graph is the 1st Pic --> Attached files    

Birds are the main predators of these beetles; they hunt the beetles by sight and pick them up off of the tree bark where they feed. A logging company clears the trees off of the island and plants younger trees as a replacement. Trees with light bark are planted on one side of the island and trees with dark bark are planted on the other side of the island. What do you predict would happen to the range of coloration in the populations of beetles on each side of the island?

Select TWO answers, one to represent the beetles living on the light colored trees and one to represent the beetles living on the dark colored trees. (2 points)

A. graph 2 below

B. graph 3 below

C. graph 4 below

D. graph 5 below

Answer:

B. graph 3 below

D. graph 5 below

Explanation:

The original population of beetles (Graph 1) shows that most individuals had an intermediate phenotype between dark and light color. The graph expresses its highest point in the middle of the phenotypic ax, while the curve´s tails coincide with light and dark colors.

Probably, most of the trees inhabiting the whole island had some darkish color tone, which beetles used to camouflage and avoid predation.

When the company cleared the area and reforested, they planted light trees on one half and dark trees on the other half of the island. This change in the environment modeled the beetled phenotype, together with predation pressure.

If we consider the whole original population, we should say that it went under a disruptive selection. But if we think about the sides of the island separately, we could say that the population living on each side went under directional selection. We are not thinking about the whole population of beetled inhabiting the whole island, but two groups inhabiting each side of the island.

Answer and Explanation:

There are many physical elements such as temperature, precipitation, humidity, altitude, vegetation, among others, that influence the presence of the insects that transmit the Chagas diseases. Its transmission seems to be enhanced by other social elements, such as the deficiency in basic services, lack of planning, the socio-economical conditions, cultural conditions. Altogether, these factors intervene in the presence of the Chagas disease, a systemic infection caused by the protozoa Trypanosoma cruzi. This protozoan is hosted by different wild and domestic mammals, transmitted to the human by hematophagous insects. The transmission occurs through dejections deposited on skin or mucose during or after the feeding process.  

Different rural areas in Central and South America are characterized by a mountain relief (temperatures between 15 and 30ºC - relative humidity between 50 and 90%), as well as by a plane relief associated with alluvial plain (temperature between 20 and 35ºC - media relative humidity of 75%). Vegetation in the mountain area provides a natural habitat to the triatomines, the insects that transmit the Chagas disease.  

Constant deforestation in mountains, soil move, the cutting down, firing, have destroyed the natural habitat of the insects, becomming the cause of their arrival to populated centers. As their environment is destroyed,    insects migrate to new areas and find refuge in precarious houses that surround the affected areas. Most of these houses have clay walls, a roof made of branches, and no floor. People that live in these conditions do not have economic resources.  Indexes of infestation in these houses are high due to the material used for their construction. Insects tend to establish near a source of food, such as domestic animals or even humans. It is also common that these houses have chicken coops and farmyards that also offer good conditions for the insects to live in.

Economic activities are important variables to consider, as these define the way of living in a population.  

Agriculture activities are performed with no control or planning. People deforest to plant, getting in contact with the insects' natural habitat, producing environmental changes, and getting in touch with them, enhancing the risks of being infected and of transportin the insects.

A heterozygous individual has two different alleles for a given trait or character, therefore can produce 2n gametes.

A person who possesses two distinct alleles of a gene is said to be heterozygous for that gene.

Each of the two alleles that this person possesses for that gene will be distributed randomly among the gametes that are produced when this person reproduces. In other words, one allele will be present in half of the person's gametes, while the other allele will be present in the other half.

Amylase is an enzyme synthesized in the pancreas and salivary glands, so it is present in the human saliva. The main function of this enzyme is to catalyze the hidrolisis of starch (or amylum, are complex carbohydrates present in some plant-based food, such as in rice and potates).

In the stomach, the most important digestive enzyme is called pepsin. This protein is produced in the stomach walls and it breaks down the proteins into smaller particles such as peptides and amino acids. Another stomach enzyme is the gastric lipase, which catalize lipid hydrolisis.

To test for the presence of starch, you can use iodine solution, which turns blue-black in the presence of starch. Lipids can be identified using a Sudan III or Sudan IV test, where lipids will appear as red or orange-stained spots.

Nucleic acids can be detected through tests like the diphenylamine test or the biuret test.

The diphenylamine test produces a blue color in the presence of DNA, while the biuret test results in a purple color in the presence of RNA.

Proteins can also be identified using the biuret test, as proteins will cause the solution to turn purple.

1. As objects move away from us, their light gets shifted into longer wavelengths or the red end of the spectrum — that's redshift. Blueshift is the opposite, when light is shifted to shorter wavelengths on the blue side of the spectrum as an object comes towards us.

2. When looking at the radiation emitted by distant stars or galaxies, scientists see emission spectra ‘shifted’ towards the red end of the electromagnetic spectrum—the observed wavelengths are longer than expected. Something causes the wavelength of the radiation to ‘stretch’.

A shift light is a warning lamp fitted to vehicles in order to indicate to the driver that maximum revolutions per minute (r/min) has almost been reached.

Moreover, the wavelength of light emitted by a moving object is shifted. This effect is called the doppler shift. If the object is coming toward you, the light is shifted toward shorter wavelengths, blue shifted.

Therefore, the larger the shift, the higher the speed of motion. The shifts in spectral lines can also be used to detect binary stars as they orbit around their center of mass and move toward and away from Earth. The shifts in spectral lines are an example of the Doppler Effect.
