Ques: Answer the following question given this paragraph: Two of the three domainsBacteria and Archaeaare prokaryotic, meaning that they lack both a nucleus and true membrane-bound organelles. However, they are now considered, on the basis of membrane structure and rRNA, to be as different from each other as they are from the third domain, the Eukarya. Prokaryotes were the first inhabitants on Earth, perhaps appearing approximately 3.9 billion years ago. Today they are ubiquitousinhabiting the harshest environments on the planet, from boiling hot springs to permanently frozen environments in Antarctica, as well as more benign environments such as compost heaps, soils, ocean waters, and the guts of animals (including humans). The Eukarya include the familiar kingdoms of animals, plants, and fungi. They also include a diverse group of kingdoms formerly grouped together as protists. Q: Organisms that lack both a nucleus and membrane-bound organelles are known as what, in general? Choices: - photosynthetic - barren - trophic - prokaryotic A:
Ans: prokaryotic
(Q).
Answer the following question given this paragraph: In seed plants, the gametophyte generation takes place in a cone or flower, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule. Pollination must occur for fertilization to take place. Zygotes develop into embryos inside seeds, from which the next sporophyte generation grows. Q: What develops into embryos inside seeds, from which the next sporophyte generation grows? Choices: - secretions - buds - pupa - zygotes A:
(A).
zygotes
Ques:Answer the following question given this paragraph: In chemical equations, reactants and products are represented by chemical symbols and formulas. Numbers called coefficients are placed in front of the symbols and formulas to show how much of each substance is involved in the reaction. Q: What does the coefficient in front of an element in a formula indicate? Choices: - number of atoms - place on the Periodic Table - time of the reaction - how much is involved in the reaction A:

Ans:how much is involved in the reaction
Answer the following question given this paragraph: Long bones ossify and get longer as they grow and develop. These bones grow from their ends, known as the epiphysis, and the presence of a growth plate, or epiphyseal line, signifies that the bone is still growing. Q: What are the ends of long bones called? Choices: - cartilage - appendage - marrow extension - epiphysis A:
epiphysis
