Which of these is a condition where the endometrial lining that is normally supposed to only be inside the uterus, ends up outside the uterus (for instance, in the pelvic cavity) and causes extreme pain during menstruation? This condition affects up to 1 in 4 women.

Answers

Answer:

Endometriosis is called the pathology

Explanation:

Endometriosis is a pathology where fibroblasts or connective tissue cells proliferate outside the fallopian tubes in the abdomen, close to the intestine, and adjacent to the ovaries, by proliferating and reducing the space between the organs, the pressure of the terminals increases nervous and during menstruation it hurts.

They are benign proliferative cell foci.

Assuming DNA is replicated correctly (so there are no mutations),
in which of the scenarios below would the gametes produced all
be genetically identical?

Answers

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.

is a product of glycolysis, pyruvate processing, and the citric acid cycle.
CO2
ATP
NADH
FADH2

Answers

the correct answer is NADH

ATP is a product of glycolysis, pyruvate processing, and the citric acid cycle.

Glycolysis is the metabolic pathway by which glucose is degraded up to two pyruvate molecules, while energy is produced in the form of ATP and NADH.

It takes place in a series of nine reactions, each catalyzed by a specific enzyme, to form two molecules of pyruvic acid, with the production of ATP.

The Krebs cycle produces the release of acetyl-CoA resulting in the formation of an acid with six carbon atoms, citric acid.

A series of sequential reactions then occur, each mediated by a specific enzyme.

In one of the reactions of the cycle, a molecule of ATP is produced, this molecule as an energy intermediate can take energy in catabolic reactions or give it up in anabolic reactions.

Therefore, we can conclude that ATP is a product of glycolysis, pyruvate processing, and the citric acid cycle.

The diploid number of chromosomes in a species is always what

Answers

Diploid meaning 2. Is a cell/ organism that has paired chromosomes, one from each parent. Humans have 23 of these.

A diploid cell always contains two complete sets of chromosomes, which is described as 2n.

What is a diploid cell?

Two complete sets of chromosomes are present in a diploid cell. The majority of human cells are diploid, with 23 chromosomal pairs totaling 46 chromosomes. This consists of a pair of sex chromosomes and 22 pairs of autosomes. The mother and father each contributed one copy of each pair of chromosomes to the individual.

Through the process of mitosis, diploid cells replicate and maintain the same number of chromosomes by making a copy of each chromosome and dividing their DNA equally among their daughter cells.

Blood cells, skin cells, and muscle cells are examples of diploid cells. These cells are called somatic cells. Different organisms have different numbers of chromosomes.

Answers

Explanation:

The factors that affects the rate of chemical reactions are;

Nature of reactants Concentration of reactants or pressureTemperature Presence of catalystSunlight

In our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.

The increasing order of food digestion is;

Compare the effectiveness of the different antibiotic drugs and chemical disinfectants. Which seems to be better at controlling bacterial growth

Answers

Answer:

Antimicrobials are classified as selective and non-selective, selective are antibiotics, non-selective are surface disinfectants that are not used in human organisms such as antibiotics.

Explanation:

That is why antibiotics are considered more effective to inhibit the growth of bacteria, since the special antibiotic that covers a certain spectrum of bacteria is selected, that is what gives them specificity and greater effectiveness, some are bacteriocidal and others bacteriostatic, considering the former as those that generate the defined death of the bacteria, and assures us more of bacterial death or inhibition of proliferation.

A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction

Answers

Answer: A. the gravitational pull of the Sun

The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.

What would happen if complexes I-IV of the electron transport chain pumped protons in the opposite direction?

a. Too much ATP would be synthesized.
b. None of the other answer options is correct.
c. No ATP would be synthesized.
d. There would be too many electrons in the mitochondrial matrix.

Answers

Answer:

The correct answer is - c. No ATP would be synthesized.

Explanation:

In the electron transport chain there are four complexes, complexes I-IV, pumps the protons from the matrix of the mitochondria into the intermembrane space. This is the downhill movement of the electrons that helps in synthesizing the ATP molecules.

If the complexes move or pump the electron uphill or against the gradient there would be no ATP formation as there would be no interchange of proton and electron interchange.

PLEASE HELP> WILL GIVE BRAINLIEST For questions 5-10, refer to the following passage:Gentlemen of the Exposition, as we present to you our humble effort at an exhibition of our progress, you must not expect overmuch. Starting thirty years ago with ownership here and there in a few quilts and pumpkins and chickens, remember the path that has led from these to the inventions and production of agricultural implements, buggies, steam engines, newspapers, books, statuary, carving, paintings, the management of drug stores and banks, has not been trodden without contact with thorns and thistles. While we take pride in what we exhibit as a result of our independent efforts, we do not for a moment forget that our part in this exhibition would fall far short of your expectations but for the constant help that has come to our educational life, not only from the Southern States, but especially from Northern philanthropists, who have made their gifts a constant stream of blessing and encouragement.The wisest among my race understand that the agitation of questions of social equality is the extremist folly, and that progress in the enjoyment of all the privileges that will come to us must be the result of severe and constant struggle rather than of artificial forcing. No race that has anything to contribute to the markets of the world is long in any degree ostracized. It is important and right that all privileges of the law be ours, but it is vastly more important that we be prepared for the exercise of these privileges. The opportunity to earn a dollar in a factory just now is worth infinitely more than the opportunity to spend a dollar in an opera house.In conclusion, may I repeat that nothing in thirty years has given us more hope and encouragement, and drawn us so near to you of the white race, as this opportunity offered by the Exposition; and here bending, as it were, over the altar that represents the results of the struggles of your race and mine, both starting practically empty-handed three decades ago, I pledge that in your effort to work out the great and intricate problem which God has laid at the doors of the South you shall have at all times the patient, sympathetic help of my race; only let this be constantly in mind that, while from representations in these buildings of the product of field, of forest, of mine, of factory, letters, and art, much good will come, yet far above and beyond material benefits will be that higher good, that let us pray God will come, in a blotting out of sectional differences and racial animosities and suspicions, in a determination to administer absolute justice, in a willing obedience among all classes to the mandates of law. This, then, coupled with our material prosperity, will bring into our beloved South a new heaven and a new earth.Booker T. Washington, "The Race Problem" (address given in Atlanta, 1895)5. In the next to last sentence, Washington's phrase, "in a willing obedience among all classes to the mandates of law" helps him create:(a) climax.(b) allegory.(c) antithesis.(d) elaborate simile.(e) understatement.6. Washington says, "The opportunity to earn a dollar in a factory just now is worth infinitely more than the opportunity to spend a dollar in an opera house." He here creates a mildly humorous contrast by using:(a) maxim.(b) personification.(c) subordination.(d) parallelism.(e) onomatopoeia.7. On the whole, Washington puts his faith in:(a) the free market system.(b) the southern states.(c) the welfare system.(d) tenant farming.(e) indefinite segregation.8. In the last paragraph Washington includes references to Christianity to:(a) show his submission to authority.(b) prevent retaliation.(c) urge his audience to join him in a holy struggle.(d) express his gratitude.(e) resurrect the past.9. In his last words, Washington speaks of bringing to the southern states "a new heaven and a new earth." Washington is using:(a) climax.(b) synecdoche.(c) antithesis.(d) allegory.(e) metaphor.10. On the whole, Washington's rhetorical choices reveal his:(a) knowledge of his audience.(b) evangelical fanaticism.(c) liking for irony.(d) hostility toward white America.(e) inclination toward anarchy. what is 11-1 and 4+2 How can 38 over 6 be expressed as a decimal?
