Answer:
H+ protons will not be delivered from the cytoplasm towards the extracellular side of the cell membrane
Explanation:
ATP synthases are enzymes that catalyze the hydrolysis of phosphate bonds in the adenosine triphosphate (ATP) or the formation of ATP from adenosine diphosphate (ADP) and phosphate. The hydrolysis of ATP produces the rotation of a ring composed of six or more structurally different ATPase C subunits. The rotation of this ring enables the delivery of H+ protons towards the extracellular membrane surface and this gradient is used to generate energy by producing ATP. In consequence, when the ATPase ring can not move, H+ will accumulate in the cytoplasm, the proton gradient through the membrane will not occur, and ATP will not be produced.
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
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.

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.

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.
The proximal convoluted tubule is A. lined with epithelial cells that lack microvilli. B. the site of glucose and amino acid reabsorption. C. permeable to water if ADH is present. D. impermeable to water. E. the site of water secretion.
Answer:
The correct answer is - option B.
Explanation:
The proximal convoluted tubule or PCT is the the part of nephron that lies in between of loop of Henle and bowman's capsule. The PCT is responsible for the most amount reabsorption of sodium, glucose, amino acids, water, potassium and chloride and reabsorbs around 65% to 100% of filtered substance.
Epithelial cells in the PCT reabsorb substances that have nutritional importance by the numerous microvilli on their surface.
Thus, the correct answer is - option B.

Consider the following chromosomes and if they are affected by hemophilia. X - unaffected X chromosome, x = X affected by hemophilia, and Y = Y chromosome. If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by the hemophilia? (1 point) A. 1/4 and 1/2 B. 1/2 and 1/4 C. 1/2 and 1/3 D. 1/4 and 1/4 Ive been stuck on this for a while now, can someone please assist?
Answer:
B. 1/2 and 1/4
Explanation:
Hemophilia is a disease inherited in humans. It is only carried on the X chromosome, hence, it is said to be X-linked. In this question;
X - unaffected X chromosome
x = X chromosome affected by hemophilia,
Y = Y chromosome
Hence, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:
Xx- X and x gametes
XY- X and Y gametes
Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY are produced.
XX (1) - unaffected normal female
Xx (1) - unaffected carrier female
XY (1) - unaffected normal male
xY (1) - affected male
Based on the questions;
- 2 out of the possible 4 children have the affected chromosomes i.e. both xY son and Xx daughter have the x chromosome. Hence, the fraction is 1/2
- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

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.
