Answer the following question given this paragraph: Centrioles are a very important part of centrosomes, which are involved in organizing microtubules in the cytoplasm. Centrosomes are associated with the nuclear membrane during prophase of the mitosis. In mitosis, the nuclear membrane breaks down and the microtubule organizing center (MTOC) of the centrosome arranges microtubules such that they interact with the chromosomes to build the mitotic spindle. Q: Centrioles are a very important part of what? Choices: - centricles - tubercles - enterocytes - centrosomes A:
(Answer)
centrosomes
Ques: Answer the following question given this paragraph: Atomic orbitals from different atoms overlap to form molecular orbitals. Q: Atomic orbitals from different atoms overlap to form what? Choices: - plasma orbitals - space orbitals - planet orbitals - molecular orbitals A:
Ans: molecular orbitals
(Q).
Answer the following question given this paragraph: Many archaeans live in close relationships with other organisms. For example, large numbers live inside animals, including humans. Unlike many bacteria, archaeans don't harm their hosts. None of them is known to cause human disease. Archaeans are more likely to help their hosts. For example, archaeans called methanogens live inside the gut of cows (see Figure below ). They help cows digest tough plant fibers made of cellulose. They produce methane gas as a waste product. Q: Archaeans produce what kind of gas as a waste product? Choices: - sulfide - carbon monoxide - carbon dioxide - methane A:
(A).
methane
Ques:Answer the following question given this paragraph: Like many other animals, sheep travel in herds. The tendency is for each individual sheep to stay with the herd. However, a sheep may sometimes wander off, depending on how strong the attraction is for a particular food or water supply. At other times, a sheep may become frightened and run off. Whether a sheep chooses to stay with the herd or go its own way depends on the balance between attraction to the herd and attraction to the outside influence. Q: What is the collective travel of sheep known as? Choices: - gaggle - load - den - herd A:

Ans:herd
Ques: Answer the following question given this paragraph: Living species of chordates are classified into three major subphyla: Vertebrata, Urochordata, and Cephalochordata. Vertebrates are all chordates that have a backbone. The other two subphyla are invertebrate chordates that lack a backbone. Members of the subphylum Urochordata are tunicates (also called sea squirts). Members of the subphylum Cephalochordata are lancelets . Both tunicates and lancelets are small and primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: Vertebrates are all chordates that have a what? Choices: - circulatory system - fossil - brain - backbone A:
Ans:
backbone
