Answers

Emission of toxin and generation of ash is related only with incinerators. Draining of liquid and requirement of substantial amount of land is related with landfills only. Generation of energy and release of greenhouse gases is related with both landfills as well as incinerators.

What are incinerators?

An incinerator is a waste-burning furnace. Pollution control equipment, such as flue gas cleaning, is included in modern incinerators.

Incinerator plant designs include moving grate, fixed grate, rotary kiln, and fluidized bed.

The descriptions can be as follows:

Generation of energy - Both, landfills produce methane gas, which is used to generate electricity, and incinerators produce heat energy, which is also used to generate energy.Emission of toxins through combustion - Incinerators emit dioxins, a hazardous chemical.Draining of liquids into the ground - this is a common problem at all landfill sites.Emission of greenhouse gases - Both landfills and incinerators emit methane and other carbon gases.Necessitates a significant amount of land - landfill site, necessitates a large amount of land to dump city wasteProduction of ash - Incinerator only.

Thus, these can be the description applies to landfills, incinerators, or both.

Atrazine is an herbicide that prevents plant growth by inhibiting photosynthesis. Atrazine works by binding to proteins in the electron transport chain of photosystem II. Once atrazine binds to the proteins, electrons can no longer travel down the chain to reach photosystem I.

Based on this information, how does atrazine stop plant growth?

A.
It prevents water from releasing oxygen, which is needed by the light-dependent reactions to fix carbon.
B.
It prevents the formation of NADH and FADH2, which are needed by the light-independent reactions to fix carbon.
C.
It prevents chlorophyll from creating electrons, which are needed by the light-dependent reactions to make sugars.
D.
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.

Answers

It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.

The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.

 

What are herbicide?

Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.

This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.

What is pathogenic invasion?

The invasion of a number with the aid of using a pathogen can be aided with the aid of using the manufacturing of bacterial extracellular materials which act in opposition to the host with the aid of using breaking down number one or secondary defenses of the frame. Medical microbiologists talk to those materials as invasins.

Active cells, referred to as fibroblasts produce collagenous fibers and floor substances. Blood vessels quickly develop into the epidermis, restoring circulation. If the damage may be very minor, the epithelial cells sooner or later repair the dermis as soon as the epidermis has been regenerated.

What is competition?

Competition is most commonly determined by the interaction of individuals competing for a small quantity of a shared resource.

It can also be characterized more broadly as the indirect or direct interactions of organisms that results in a change in fitness when the organisms share the same resource.

When members of multiple species start competing for the same resource, this is known as interspecific competition.

Woodpeckers and squirrels frequently end up competing for nesting rights in the very same holes and spaces in trees, while African savanna lions and cheetahs compete for the same antelope and gazelle prey.

As in the given case, the water supply is being limited by the humans, it will most likely to cause the competition for the resource. It will lead to shrinkage of deer population along with wolf population.

Why does the Department of Homeland Security target foot-and-mouth disease?

Answers

The bottom- and- mouth complaint contagion has been honored since at least the 16th century.

It's characterized by fever, pocks on the bases and mouth, loss of appetite, drooling and lameness. Infected herds of creatures are generally destroyed.

Large quantities of the contagion are present in all body concealment, including breath, and are readily transmitted to other creatures. The contagion can also survive on the ground for extended ages of time and can be transferred on tires, thrills and clothes. It has indeed been shown to be carried long distances by wind.

The United States has been free of the complaint since 1929, but that isn't a guarantee it'll not return. Britain was free of the complaint for 34 times before a 2001 outbreak that needed the destruction of 10 million cows.

FMD contagion is largely contagious in cloven- mashed creatures, including cattle, gormandizers, small ruminants. Encyclopedically, FMD has a significant impact on beast trade economics and expansive nonsupervisory programs live in the U.S. to grease identification of, response to, and control of the complaint. With one in nine Americans employed in the husbandry or confederated diligence, the goods of an FMD outbreak in the U.S. would be ruinous ­ – estimated at nearly$ 200 billion in lost profit over 10 times across affected diligence.

Therefore the Department of Homeland Security target foot-and-mouth disease.

The heart is the main pumping organ of the body. The human heart is divided into four chambers two atria and two ventricles. The human heart consists of three layers- epicardium, myocardium, and endocardium.

The middle layer of the heart (myocardium) consists of cardiomyocytes or muscle cells. These cells receive nerve stimulation from the atrioventricular nodes and sinoatrial nodes.

What are Epithelial cells?

Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform a variety of functions and exhibit different shapes, size and arrangement which makes up different tissues.

Which kind of mutation is most likely to lead to a new trait in an organism?

A. A frameshift mutation

B. A nonsense mutation

C. A missense mutation

D. A silent mutation

Answers

A frameshift mutation is a kind of mutation which is most likely to lead to a new trait in an organism. Thus, the correct option is A.

What is Mutation?

A Mutation may be defined as the sudden, stable, and inheritable alterations in the genomic sequence of an organism.

A frameshift mutation occurs when the reading frame modifies the grouping of the bases and thereafter transforms the amino acids that are encoded. Here, the encoded protein is non-functional.

A missense mutation arises when there is a blunder in the DNA code and one of the DNA base pairs is altered.

A nonsense mutation occurs when a single change in the base sequence outcomes in the exhibition of a stop codon, thereby concluding protein synthesis prematurely.

How does someone achieve a unified self?

Answers

Answer:

please mark me as brain list

Explanation:

The unified self is a flawed construct. Experience changes us, even at the core. People change us just by being with us. It doesn't have to be a long term relationship. Our minds may not have the plasticity they once had but we adapt daily to the people around us and, in a slower fashion, tide rather than waves rather than ripples, we the ebb and flow of experience changes the "I think" that creates our values and judgements, which changes the experiences we seek then have which again works on the way we view the world.

A possible reason we are able to change when we are with different types of people is that we have a certain number of roles at our disposal. I've noticed this, on an extreme level, with some coworkers. I wondered how they could change so much when they got to the office. They'd suddenly become very business-like and at first I thought they were play acting. They were, in a sense, but I believe their identity changed when they walked through the office door. They were no longer the guy or girl I'd just ridden to work with, they were such and such part of the hierarchy and their behavior wasn't all a put on, though some of everyone's behavior in every role is, it was who they were then.

It took being asked to take a work related personality test that clued me in. The test results came back. One part of results outlined our scores for introversion/extroversion scores at home and at work. The scale was -50 to +50 where the score determined one's level of introversion (-) or extraversion (+). I scored -33 at home and a +33 at work. The automatic scoring algorithm suggested that it was likely I was under a lot of internal stress because of this. I was. I used to have dry heaves when I transitioned from work to home. That part of the results wasn't the only part rang true though so I took it seriously.

How close the roles we play with different people are to each other might be an indicator of how unified we are. If you were to scale our unification factor from 0 to 1 I would have been considered a 0.33 based on my introversion/extraversion scores, if that was the only score that mattered. More things the behavior than others matters, of course. Perhaps people who are very different in differing situations experience more cognitive dissonance. It would be interesting knowing.

One can achieve a unified self when the ego desire of the self and the altruistic urge of the higher self are co-ordinated and reconciled by the unified will of different personas.

What is Unified self ?

A person's "composite" persona, also known as the "self" that incorporates all of the other personalities present in their interactional style, is referred to as the "unified self ."

The majority of cognitive scientists and brain specialists hold that the self is not a single, cohesive "thing," but rather a collection of distinct modules or mental systems.

Our perspective of oneself could readily alter if we are exposed to a logical argument that may modify our perception because it is merely a collection of separate modules.

Therefore the concept of achieving a unified self is still unclear and psychologists are constantly looking for an answer regarding same.
