Ques: Answer the following question given this paragraph: H0 = 20km/s Mly. Explanations of the large-scale characteristics of the universe are intimately tied to particle physics. The dominance of matter over antimatter and the smoothness of the CMBR are two characteristics that are tied to particle physics. The epochs of the universe are known back to very shortly after the Big Bang, based on known laws of physics. The earliest epochs are tied to the unification of forces, with the electroweak epoch being partially understood, the GUT epoch being speculative, and the TOE epoch being highly speculative since it involves an unknown single superforce. The transition from GUT to electroweak is called spontaneous symmetry breaking. It released energy that caused the inflationary scenario, which in turn explains the smoothness of the CMBR. Q: The epochs of the universe are known back to very shortly after what 'explosive' event? Choices: - Biggest bang - Explosive bang - major bang - big bang A:
Ans: big bang

Ques: Answer the following question given this paragraph: Regular weight-bearing exercise can reduce the risk of osteoporosis. Apply lesson concepts to explain why. Q: Regularly performing weight-bearing exercise can reduce the risk of what condition that affects bones? Choices: - psoriasis - marrow deficiency - arthritis - osteoporosis A:
Ans: osteoporosis

Ques: Answer the following question given this paragraph: During transcription, a copy of mRNA is made that is complementary to a strand of DNA. In eukaryotes, mRNA may be modified before it leaves the nucleus. Q: In eukaryotes, mrna may be modified before leaving what? Choices: - ribosome - mitochondria - epidermis - nucleus A:
Ans: nucleus

Ques: Answer the following question given this paragraph: Simple Epithelium The shape of the cells in the single cell layer of simple epithelium reflects the functioning of those cells. The cells in simple squamous epithelium have the appearance of thin scales. Squamous cell nuclei tend to be flat, horizontal, and elliptical, mirroring the form of the cell. The endothelium is the epithelial tissue that lines vessels of the lymphatic and cardiovascular system, and it is made up of a single layer of squamous cells. Simple squamous epithelium, because of the thinness of the cell, is present where rapid passage of chemical compounds is observed. The alveoli of lungs where gases diffuse, segments of kidney tubules, and the lining of capillaries are also made of simple squamous epithelial tissue. The mesothelium is a simple squamous epithelium that forms the surface layer of the serous membrane that lines body cavities and internal organs. Its primary function is to provide a smooth and protective surface. Mesothelial cells are squamous epithelial cells that secrete a fluid that lubricates the mesothelium. In simple cuboidal epithelium, the nucleus of the box-like cells appears round and is generally located near the center of the cell. These epithelia are active in the secretion and absorptions of molecules. Simple cuboidal epithelia are observed in the lining of the kidney tubules and in the ducts of glands. Q: The thin scale-like or flat shape of what cells fits their primary function, to provide a smooth and protective surface? Choices: - technique epithelium - kind epithelium - basic epithelium - simple epithelium A:
Ans:
simple epithelium
