Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.
Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula?
SELECT AN ANSWER
This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.
One of the versions is a mistake, the correct form should be Cu2S.
Answer:
option 3
Explanation:
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
There are two forms for writing the chemical formula because copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+)
Copper is a transition metal with variable oxidation states. The oxidation states of copper is what determines the name of CuS and Cu₂S.
Now, we shall determine the oxidation states of copper in each compound.
For CuS:
CuS = 0
S = –2
Cu =?Cu + S = 0
Cu + (–2) = 0
Cu – 2 = 0
Collect like terms
Cu = 0 + 2
Cu = +2For Cu₂S:
Cu₂S = 0
S = –2
Cu =?2Cu + S = 0
2Cu + (–2) = 0
2Cu – 2 = 0
Collect like terms
2Cu = 0 + 2
Divide both side by 2
Cu = 2/2
Cu = +1From the calculations made above, we can see that copper has oxidation state of +2 in CuS and +1 in Cu₂S
Thus, we can conclude that Copper is a transition metal with two possible ionic states and this accounts for the different names of CuS and Cu₂S

Do environmental or genetic factors affect growth of organisms most?
Answer:
Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.
I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

So meiosis produces egg or sperm
Answer:
Your answer is correct, it is eggs
Explanation:
In meiosis in females is called oogenesis while in males it is called spermatogenesis so it does produce a little bit of both because it needs to produce the chromosomes for the offspring half male and half female. It also produces 4 gamete cells and around that time can form the offspring which then can form whatever reproductive organ either it's going to be a girl or a boy. But in meiosis, it mostly produces the eggs because the sperm fertilizes the egg hence the whole Meiosis I and II processes.

A simple random sample of 25,000 individuals are surveyed in order to determine the prevalence of individuals that contracted the flu in the past year. Assuming 4,250 individuals indicated they had been diagnosed with the flu at some point in the past year, what is the prevalence of flu for the past year, as indicated from the survey participants?
A. 8.30%
B. 83.0%
C. 17.0%
D. 1.70%
Answer:
C. 17.0%
Explanation:
A random sampling of human populations is done to check the frequency of a particular infection. The proportion of the individuals in the total population that suffered the infection at any time during the year are counted. The proportion of the individuals infected any time during the year is divided by the total number of the individuals surveyed and the percentage is taken to calculate the prevalence of the infection in the sampled population.
Here, the total number of the individuals that were infected with flu in the last year= 4250.
The total number of the checked individuals= 25,000.
So, the proportion of the individuals infected with flu in this population= 4250/25000 x 100= 17%
Answer: It is C. 17.0%

Which stage of the cell cycle happens directly after cytokinesis?
A
mitosis
B
M phase
C
anaphase
D
interphase
The cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.
What is the cell cycle's importance?The cell cycle consists of the interphase and the division phase, and in the interphase, the cell spends most of the time preparing itself for the cell division and consists of the G1, S, and G2 phases. Following the interphase, the cell enters the division phase, which is mitosis or meiosis, and divides, with the daughter cells potentially entering the cell cycle via the interphase.
Hence, the cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.
This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.
