PLZ help I need an answer ASAP
50 points to the first person!!!!!

Answers

Answer:

Your stomach acid helps you break down and digest your food. Sometimes, a higher than normal amount of stomach acid can be produced. This can lead to symptoms like abdominal pain, nausea, bloating, and heartburn.

Explanation:

brainliest plz

Answer:Stomach acid, or gastric acid, is a watery, colorless fluid that’s produced by your stomach’s lining.It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract.In order to break down everything from meat to tough, fibrous plants, stomach acid has to be highly acidic.Your body is designed to handle normal levels of stomach acid so it doesn’t cause you any illness or health complications.

Explanation:Stomach acid encounters a lot of things on behalf of your body. It breaks down the foods you eat into easier-to-digest particles. It also acts as the first line of defense against pathogens and microbes that could make you sick.

Explain the role of gravity and inertia on the motion of objects in the solar system.

Answers

Like all objects with mass, planets have a tendency to resist changes to their direction and speed of movement. This tendency to resist change is called inertia, and its interaction with the gravitational attraction of the sun is what keeps the planets of the solar system, including Earth, in stable orbits.

Answers

Answer:

Actually, Sherman, there are more black moths than white ones because of natural selection. The black moths blend into the environment, while the white moths do not. This means that the predators of the moths will find and eat more white moths than black moths. Then, this leads to more black moths and fewer white moths, since black moths have a better chance of surviving and reproducing.

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increase. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Help if u understand pleas and thanks Which group of words does the author use to advance the plot through the characters?from Sense and Sensibility CHAPTER IVby Jane Austen "What a pity it is, Elinor," said Marianne, "that Edward should have no taste for drawing." "No taste for drawing!" replied Elinor, "why should you think so? He does not draw himself, indeed, but he has great pleasure in seeing the performances of other people, and I assure you he is by no means deficient in natural taste, though he has not had opportunities of improving it. Had he ever been in the way of learning, I think he would have drawn very well. He distrusts his own judgment in such matters so much, that he is always unwilling to give his opinion on any picture; but he has an innate propriety and simplicity of taste, which in general direct him perfectly right." Marianne was afraid of offending, and said no more on the subject; but the kind of approbation which Elinor described as excited in him by the drawings of other people, was very far from that rapturous delight, which, in her opinion, could alone be called taste. Yet, though smiling within herself at the mistake, she honoured her sister for that blind partiality to Edward which produced it. "I hope, Marianne," continued Elinor, "you do not consider him as deficient in general taste. Indeed, I think I may say that you cannot, for your behaviour to him is perfectly cordial, and if that were your opinion, I am sure you could never be civil to him." Marianne hardly knew what to say. She would not wound the feelings of her sister on any account, and yet to say what she did not believe was impossible. At length she replied: "Do not be offended, Elinor, if my praise of him is not in every thing equal to your sense of his merits. I have not had so many opportunities of estimating the minuter propensities of his mind, his inclinations and tastes, as you have; but I have the highest opinion in the world of his goodness and sense. I think him every thing that is worthy and amiable." "I am sure," replied Elinor, with a smile, "that his dearest friends could not be dissatisfied with such commendation as that and I do not perceive how you could express yourself more warmly." Marianne was rejoiced to find her sister so easily pleased. "Of his sense and his goodness," continued Elinor, "no one can, I think, be in doubt, who has seen him often enough to engage him in unreserved conversation. The excellence of his understanding and his principles can be concealed only by that shyness which too often keeps him silent and you know enough of him to do justice to his solid worth. But of his minuter propensities, as you call them you have from peculiar circumstances been kept more ignorant than myself. He and I have been at times thrown a good deal together, while you have been wholly engrossed on the most affectionate principle by my mother and I have seen a great deal of him, have studied his sentiments and heard his opinion on subjects of literature and taste; and, upon the whole, I venture to pronounce that his mind is well-informed, enjoyment of books exceedingly great, his imagination lively, his observation just and correct, and his taste delicate and pure. His abilities in every respect improve as much upon acquaintance as his manners and person. At first sight, his address is certainly not striking; and his person can hardly be called handsome, till the expression of his eyes, which are uncommonly good, and the general sweetness of his countenance, is perceived. At present, I know him so well, that I think him really handsome; or at least, almost so. What say you, Marianne?" "I shall very soon think him handsome, Elinor, if I do not now. When you tell me to love him as a brother, I shall no more see imperfection in his face, than I now do in his heart." An isosceles triangle has two sides of equal lenght.
