Answer the following question given this paragraph: Like a chemical compound, a mixture consists of more than one chemical substance. Unlike a compound, a mixture does not have a fixed chemical composition. The substances in a mixture can be combined in any proportions. A mixture also does not involve a chemical reaction. Therefore, the substances in a mixture are not changed into unique new substances, and they can be separated from each other without a chemical reaction. Q: What is the term for a combination of substances in which there is no chemical reaction? Choices: - a combination - a solute - a solution - a mixture A:
(Answer)
a mixture

Q: In hornworts, the horns are the sporophytes that rise up from what? Choices: - the roots - the polyol gametophyte - the breaza gametophyte - the leaflike gametophyte A:
Ans: the leaflike gametophyte
(Q).
Answer the following question given this paragraph: Humans display dramatic deleterious effects with autosomal trisomies and monosomies. Therefore, it may seem counterintuitive that human females and males can function normally, despite carrying different numbers of the X chromosome. In part, this occurs because of a process called X inactivation. Early in development, when female mammalian embryos consist of just a few thousand cells, one X chromosome in each cell inactivates by condensing into a structure called a Barr body. The genes on the inactive X chromosome are not expressed. The particular X chromosome (maternally or paternally derived) that is inactivated in each cell is random, but once the inactivation occurs, all cells descended from that cell will have the same inactive X chromosome. By this process, females compensate for their double genetic dose of X chromosome. In so-called "tortoiseshell" cats, X inactivation is observed as coat-color variegation (Figure 7.10). Females heterozygous for an X-linked coat color gene will express one of two different coat colors over different regions of their body, corresponding to whichever X chromosome is inactivated in the embryonic cell progenitor of that region. When you see a tortoiseshell cat, you will know that it has to be a female. Q: When female mammalian embryos consist of just a few thousand cells, one x chromosome in each cell inactivates by condensing into a structure called what? Choices: - lewy's body - morton body - baker body - barr body A:
(A).
barr body
Ques:Answer the following question given this paragraph: Microbial Genomics: Metagenomics Traditionally, microbiology has been taught with the view that microorganisms are best studied under pure culture conditions, which involves isolating a single type of cell and culturing it in the laboratory. Because microorganisms can go through several generations in a matter of hours, their gene expression profiles adapt to the new laboratory environment very quickly. In addition, the vast majority of bacterial species resist being cultured in isolation. Most microorganisms do not live as isolated entities, but in microbial communities known as biofilms. For all of these reasons, pure culture is not always the best way to study microorganisms. Metagenomics is the study of the collective genomes of multiple species. Q: Because microorganisms can go through several generations in a matter of hours, their gene expression profiles adapt to the new laboratory environment very quickly. in addition, the vast majority of bacterial species resist being cultured in this? Choices: - water - substrate - colonies - isolation A:

Ans:isolation
Answer the following question given this paragraph: When fuel is burned, most of the energy is released as heat. Some of this heat can be used to do work. Heat cooks food or warms your house. Sometimes the heat is just waste heat. It still heats the environment, though. Q: When fuel is burned, most of the energy is released in what form? Choices: - precipitation - carbon dioxide - humidity - heat A:
heat
