In "The tragedy of the Commons", the author doesn't consider: B. that humans are social and depend on one another.

The tragedy of the Commons can be defined as an economic concept in which people (humans) with access to a shared resource act in their own selfish interest, while retroactively depleting this common resource.

This ultimately implies that, humans weren't considered to be social and dependent on one another by the author who wrote the tragedy of the Commons, they were rather selfish and self-centered.

A river system is made up of a river and its tributaries.

A river system is a term used to describe the broader networks of streams, lakes, and rivers that are tributaries and distributaries of a larger river. For instance, the Mississippi River system includes the Ohio, Red, and Missouri rivers, all of which drain into the Mississippi River. Due to its interconnectedness, the condition of one river may have an effect on the health of the other rivers in the same river system. A river system can also include other types of terrain, such as the wetlands and flood plains that are affected by a major river and its tributaries and distributaries. The majority of the time, rivers have a primary source, such as snowmelt from a mountain that cascades into a number of streams, which eventually merge to form a river that empties into a much bigger river. This is an illustration of a river network. River systems are ecosystems from an environmental perspective, and if even one component of the system is contaminated or destroyed, it may have a severe impact on things like water quality and the health of plants and animals. For instance, the effects of high pollution levels or prolonged drought near a river's source will be felt throughout the rivers and lands that make up the river system.

An example of this is the Amazon River in Brazil (South America).

A river system is made up of a river and its tributaries.

One of the most adaptable restorative materials in dentistry is dental amalgam. It accounts for over 75% of all restorative materials used by dentists.

Dental amalgam is a mixture of liquid mercury and metal alloys used to treat cavities caused by tooth decay in dentistry. [1] Mercury (50%) is typically found in low-copper amalgam, along with silver (22–32%), tin (14%), zinc (8%), and other trace metals.

Because of the constant expansion and contraction of amalgam fillings, they can sometimes shatter the tooth. Leakage is also less likely with composite fillings. A leaking filling indicates there is a small breach between the filling and your tooth, which allows dirt and saliva to enter and cause decay.

Answer:

Initiation Transcription or (promoter)

Explanation:

∙ Transcription is the process of RNA production from DNA.

∙ During transcription, RNA polymerase produces a copy of a gene from the DNA to mRNA.

∙ During transcription, the DNA location at which RNA polymerase interacts is termed a promoter.

∙ Transcription begins with attachment of sigma factor proteins to the RNA polymerase holoenzyme, therefore, allowing it to bind to promoter DNA.

∙ RNA polymerase forms a transcription bubble, which divides the two strands of the DNA helix.

∙ Then RNA polymerase proceeds towards the transcription start site for the process of transcription.

Transcriptional promoter sites are found in the DNA, 'upstream' of the gene to be transcribed.

Some of them are called 'TATA box'.

Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the transcription initiation site.

Core promoter, proximal promoter, and distal promoter are the examples of different promoters.

So we can conclude that Transcriptional promoter sites are found in the DNA, 'upstream' of the gene to be transcribed.

The amount of water that condensed at the top of the terrarium change as plants sprouted and grew because water, oxygen and nutrients are  very essential elements for growth.

The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities. Nutrients (macro and micro essential elements) are required by plants for the synthesis of protoplasm and act as source of energy.

Thus as plant grows it needs more water to provide to it's larger plant body and which causes decrease in the amount of water that condensed at the top of the terrarium.

b. YY and yy

2. Answer these questions: a. What are the resulting phenotypes? b. Are there any blue kernels? c. How can you tell whether or not there are blue kernels?

3. Set up and complete a Punnett square for a cross of two of the F1 from Step 1 (above).

4. Answer these questions: a. What are the genotypes of the F2 generation? b. What are their phenotypes? c. Are there more or fewer blue kernels than in the F1 generation?

5. Identify the four possible gametes produced by the following individuals (S = smooth, s = wrinkled):

a. YY Ss

b. Yy Ss

Punnett squares are used to get the genotypic and phenotypic frequencies among the progeny produced from a cross. Punnett squares and answers below.

The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.

Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.

In the exposed example,

Diallelic genes that codes for color

Y = yellow ⇒ dominant allele

y = blue ⇒ recessive allele

We will assume complete dominance, meaning that genotypes with at least one dominant allele will express yellow.

1)

a- Cross 1

Parentals)   YY   x    Yy

Gametes) Y   Y      Y   y

Punnett square)      Y        Y

                       Y     YY      YY

                        y     Yy      Yy

F1) Genotype

1/2 = 50% of the progeny is expected to be homozygous dominant, YY

1/2 = 50% of the progeny is expected to be heterozygous, Yy

   Phenotype

100% of the progeny is expected to be yellow.

b- Cross 2

Parentals)  YY   x    yy

Gametes) Y     Y     y    y

Punnett square)      Y        Y

                       y     Yy     Yy

Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

The pancreatic alpha cells that produce glucagon are peptide hormones. It is thought to be the body's primary catabolic hormone since it increases blood levels of glucose and fatty acids. Additionally, it is prescribed as medicine to treat a variety of medical ailments.

When the blood glucose level is too low, the pancreas produces glucagon. Glycogenolysis—the process by which the liver releases glucose into the bloodstream—is triggered by glucagon and occurs in the liver. On the other hand, high blood sugar levels encourage the production of insulin. Insulin-dependent tissues can absorb and utilize glucose with the help of insulin. As a result, the feedback mechanism that maintains steady blood glucose levels includes both glucagon and insulin. Energy expenditure is increased by glucagon, which is higher during stressful situations. The secretin family of hormones includes glucagon.

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.

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.
