There is a considerable amount of chemical energy stored in a tall tree. For instance, the wood could be burned to make a great deal of heat.

From where does the chemical energy come?

Answers

Answer:

The correct answer is - the sun.

Explanation:

When a plant is in initial stages there isgradual increase in  the mass of the plant which become later as a tall tree by the process of the phostosynthesis as it increase the storage of glucose or sugar in the tree. The mass of the tree by glucose storage is due to the carbon molecules of CO2 moleules.

Photosynthesis is the process that involves the trapping of the light come from the sun which is then converted in the cheical energy in the form of the glucose or the sugars.

The chemical energy present in the tall trees comes from the Sun.  

• Through the process of photosynthesis, the tall trees convert energy from the Sun, that is, light energy into the chemical energy.  

• The majority of this energy is stored in the trees in the form of compounds known as carbohydrates.  

• When animals consume trees and its components, they consume and absorb some of this energy, that is, stored as chemical energy into the compounds protein and fats.  

Thus, the green plants and trees are the source of energy, that is, used for various purposes. Through the process of photosynthesis, the light energy coming from the Sun gets converted into the chemical energy that gets stored as carbohydrates.

The weather this year has been unusually dry; nevertheless, the number of cattle in the herd has increased.
wildfire control
erosion control
disease control
water conservation control

Answers

Answer:

wildfire control

Explanation:

Cattle grazing has been used as an effective wild fire control.  On a yearly basis, grazing can reduce the amount and alter the continuity of fine fuels, potentially changing wildfire fire spread and intensity (Stand et al., 2018).

Historically, however, grazing pressure was one of greatest tools for reducing fine fuels that carry wildfires (Miller et al., 1994).

Livestock are very important in reducing the risk of wildfire because they remove the fine fuels; this removal of fine fuels by livestock grazing results in less occurrences of fire hazards.

Answer:

the correct answer is "erosion control"

Explanation:

The correct answer is erosion control. A high animal load on grasslands experiencing drought can lead to serious erosion problems. This situation can be exacerbated if winds remove topsoil; combined with overgrazing and drought, any new moisture could further the erosion of the soil.

2. Protein A has a binding site for ligand X with a Kd of 10-6M. Protein B has a binding site for ligand X with a Kd of 10-9M. Which protein has a higher affinity for ligand X

Answers

Answer:

Protein B has a higher affinity for ligand C than protein A

Explanation:

Binding affinity is a measure of the strength of the bonds or interactions between a single biomolecule or receptor to its ligand. A ligand is usually a small molecule that binds to a specific receptor.

The receptor is usually a large molecule that contains a specific site for the binding of ligand.

Binding affinity is usually measured by the equilibrium dissociation constant (KD). The equilibrium dissociation constant KD is a ratio of the dissociation and the association of ligand to the receptor. The value of KD is used to evaluate and compare the strengths of bimolecular interactions.  The larger the KD value, the more weakly the target molecule and ligand are attracted to and bind to one another.

The higher the dissociation constant (KD), the weaker the affinity is between the interacting molecules, whereas, the smaller the KD value, the greater the binding affinity of the ligand for its target.

Protein B has a KD value of 10⁻⁹ M while Protein A has a KD of 10⁻⁶ M.

Ration of KD of protein B to protein A = 10⁻⁹ M/10⁻⁶ M = 10⁻³

Therefore, protein B has a KD value which is 1000 times smaller than the KD of protein A.

compare to the spread of foodborne and person-to-person pathogens?

Answers

Answer:

4.Compare: How does the spread of a foodborne pathogen compare to the spread of theperson-to-person pathogen you studied in activity A?A foodborne pathogen is much slower to spread than a person-to-person pathogen. The smallconfined room makes it easier and much faster to spread the virus. Foodborne only getsinfected by consuming contaminated food. On the other hand, a person-to-person pathogendoes not require that.5.Predict: How would you expect the spread of an airborne disease to be similar to anddifferent from the spread of a foodborne disease and a person-to-person disease?The similarity of a airborne disease and both a foodborne and person-to-person disease isnumerous. One of the similarities is that they are all diseases. Another similarity is that they canall infect and spread. These diseases not only have similarities but they also have differences.One of the many differences they have is the way they spread and infect. Airborne diseasesspread by a victim breathing in pathogens in the air. This is different from how foodborne andperson-to-person diseases spread because foodborne diseases spread by being consumed andperson-to-person diseases spread by contact of two people. In conclusion all the types ofdiseases including foodborne, person-to-person, and airborne all posses numerous similaritiesand as well as numerous differences.6.Experiment: Run a few simulations with the airborne pathogen.A.What patterns do you notice in how the airborne pathogen spreads?There are no patterns on how the airborne pathogen spreads. People get infected with thedisease in different parts of the room randomly.B.How does the spread of an airborne pathogen compare to the spread of foodborneand person-to-person pathogens?An airborne disease spreads randomly as the disease is in the air. It depends if the disease isinhaled. On the other hand, foodborne and person-to-person pathogens are predictable.Foodborne pathogens spread from contaminated food and person-to-person pathogens arespread from contact of infected people.7.Think about it: Suppose there is an infectious disease at a party. How could doctors tell if thedisease was foodborne, airborne, or transmitted person to person?Doctors could look for patterns to find out what type of transmission the pathogen inflicted. Forfoodborne, they could make a chart and find out who ate the food and who got the disease or,they could microscope the food to find pathogens. A way for finding person to person pathogenswould be to go to the bathroom at the party and examine the towel for diseases or find out if

Secondary succession is faster than primary succession C. Primary and secondary succession usually proceed at the same rate because they both followed a large disturbance. D. Succession rates would depend on the number of early arriving facilitator species.

Answers

Answer:

The answer is option D "Succession rates would depend on the number of early arriving facilitator species"

Explanation:

Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.

In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.

Succession is a progression of reformist changes in the structure of an ecological community over the long run.

In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.

In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.

The correct answer is - option D. A person rubs a shoe on a rug, causing extra electrons to be transferred to the shoe.

Explanation:

Current electricity is a flow of charged particles that moves through space or any type of electrical conductor. Usually, the transfer of the electric current takes place through a wire. There are many examples of current electricity such as lightning and static electric charge.

Electric static charge is generated due to the imbalance of particles present on the surface or within the material, normally friction leads to this imbalance in particles of the material such as when a person rubs his shes on rug created an imbalance in the electrons and then transfer to the shoe.
