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.

How does someone achieve a unified self?
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.

which dental material would you say is the most versatile and widely used today and why?
One of the most adaptable restorative materials in dentistry is dental amalgam. It accounts for over 75% of all restorative materials used by dentists.
What is amalgam?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.

e)They are proteins of the cytoplasm
Transcriptional promoter sites are found in the DNA, 'upstream' of the gene to be transcribed.
Some of them are called 'TATA box'.
Where transcriptional promoter sites are located?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.

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.
What is a punnett square?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

Which endocrine hormone promotes the release of glucose from the liver and into the bloodstream?
Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.
What is glucagon?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.

Did the amount of water that condensed at the top of the terrarium change as plants sprouted and grew? described what you observed, using data from your experiment. why do you think this happened ?
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.
