A group of coordinately regulated structural genes with related metabolic functions, plus the promoter and operator sites that control their transcription, is called a/an ___________.
Answer:
They are called promoter and regulatory genes.
Explanation:
There are different genes responsible for regulating transcription:
These are the inhibitors, promoters and regulators.
Regulatory genes are in charge of regulating that promoter or inhibitor genes remain intact or do not present mutations.
Promoter genes promote cell replication, hence transcription.
In the case of malignant or benign neoplasms, there must be yes or if the affection of a regulatory gene plus the affection of an inhibitory or promoter gene.

What effect does insulin have on the body? It raises blood-sugar levels. It lowers blood-sugar levels. It raises glucagon levels. It lowers glucagon levels.
it regulates blood sugar level.
Explanation:
Insulin helps control blood glucose ( sugar) levels by signaling the liver and muscle and fat cells to take in glucose ( sugar) from the blood. Insulin therefore helps cells to take in glucose (sugar) to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose ( sugar) and store it as glycogen.

what are some non examples of hydroshere
The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.
What are some non examples of hydrosphere?It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.
Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.
Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

which promotes a more substainable use of resource
Answer:
Decreasing overconsumption
Explanation:
During the last years, environmental concerns have increased due to high levels of contamination and destruction of ecosystems. In response to this situation, a worldwide movement has emerged that promotes environmentally friendly practices that aim at reaching sustainability. The term "sustainability" refers to a global trend to find the balance between the conservation of nature and the use of natural resources; one of the most important principles to achieve this is to reduce consumption; this leads to a decrease in the negative impact of human societies as fewer resources are taken from nature and thus, ecosystems are preserved. So, the correct answer is decreasing overconsumption
Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.
a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain
Answer:
a. Hypertonic solution
b. Hypotonic solution
Explanation:
There are basically 3 types of solutions in biology,
1) Isotonic-Same concentration of solute and solvent inside the grape and in the solution.
2)Hypotonic solution-More concentration of solvent in the solution than in the grape.
3)Hypertonic solution-More concentration of solvent in the grape than in the solution.
Now,
a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.
b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.

Look at the DNA sequence (1st Picture) Which sequence shows a substitution mutation? (2nd Picture)
Also, can you explain how you got the correct answer?
Answer:
Sequence A
CGTTACTGCAAT to CGTGACTGCAAT
Explanation:
Mutation refers to any change, whether big or small, that occurs in the nucleotide sequence of a DNA/gene. This change can either be caused by replicational errors or induced by mutagens. Mutation can be of different types depending on the effects on the affected organism (mutant).
A substitution mutation is a kind of mutation in which one or more nucleotide base is replaced by another in a sequence. This is the case here as the
original sequence: CGTTACTGCAAT
Mutated sequence: CGTGACTGCAAT
The fourth base, T has been replaced by G in the upper strand of the DNA sequence.

here are times where you will be provided with BUD dates. When you do not have access to the BUD dates, you will have to determine that date yourself. What is the appropriate BUD date for a water containing oral formulation? Not later than 14 days Not later than 30 days
Answer:
Explanation: Not later than 14 days.
Beyond Use Date (BUD) is the date after which a compounded sterile preparation may not be stored or transported. This time is calculated from the date of compounding, and it is different from expiration date. This is because the BUDs are assigned with a different approach from those applied to assigning expiration dates to manufactured drug products. Also, compounded preparations are intended for administration following short-term storage. So, the BUD is the date after which a compounded preparation shall not be used. A reliable BUD is established to ensure that the preparation has an accepted quality and purity at least until the labeled BUD.
BUD is calculated by:
Type of container in which it is packagedHow long the medication will be takenType of drugHow fast is the drug degradatedStorage conditionsDosage of the medicationNature of the drug and its degradation mechanism Potential for microbial proliferation in the preparationFor Nonaqueous Formulation, the BUD is not later than 6 months or the time remaining until the earliest expiration date of any API (Active pharmaceutical ingredient), whichever is earlier.
For Water-Containing Oral Formulation, the BUD is not later than 14 days when it is stored at controlled cold temperatures.
For Dermal and Mucosal Liquid, Semisolid Formulations/Water-Containing Topical, the BUD is not later than 30 days.

what are sex hormones?why are they named so? state their function.
Answer:
Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.
The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.
In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.
Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question... Thank you for the question.
