Answer the following question given this paragraph: All reptiles are heterotrophs, and the majority eats other animals. Heterotrophs that eat only or mainly animals are called carnivores. Large carnivorous reptiles such as crocodilians are the top predators in their ecosystems. They prey on large birds, fish, deer, turtles, and sometimes farm livestock. Their powerful jaws are strong enough to crush bones and turtle shells. Smaller carnivorous reptilesincluding tuataras, snakes, and many lizardsare lower-level predators. They prey on small animals such as insects, frogs, birds, and mice. Q: What is the term for heterotrophs that eat only or mainly animals? Choices: - parasites - predators - omnivores - carnivores A:
carnivores

Answer the following question given this paragraph: chloride, NaCl. When Na 2 HPO 24 (the weak acid) comes into contact with a strong base, such as sodium hydroxide (NaOH), the weak acid reverts back to the weak base and produces water. Acids and bases are still present, but they hold onto the ions. Q: When na 2 hpo 24 (the weak acid) comes into contact with a strong base, such as sodium hydroxide (naoh), the weak acid reverts back to the weak base and produces what? Choices: - rock - plasma - air - water A:
(Answer)
water
Ques: Answer the following question given this paragraph: Darwin finally published his theory of evolution by natural selection in 1859. He presented it in his book On the Origin of Species . The book is very detailed and includes a lot of evidence for the theory. Darwin's book changed science forever. The theory of evolution by natural selection became the unifying theory of all life science. Q: Which landmark book on evolution via natural selection did charles darwin publish in 1859? Choices: - on the origin of mammals - on the ethnic of species - on various kinds of animals - on the origin of species A:
Ans: on the origin of species

Answer the following question given this paragraph: Hydrogen Bonds Ionic and covalent bonds are strong bonds that require considerable energy to break. However, not all bonds between elements are ionic or covalent bonds. Weaker bonds can also form. These are attractions that occur between positive and negative charges that do not require much energy to break. Two weak bonds that occur frequently are hydrogen bonds and van der Waals interactions. These bonds give rise to the unique properties of water and the unique structures of DNA and proteins. When polar covalent bonds containing a hydrogen atom form, the hydrogen atom in that bond has a slightly positive charge. This is because the shared electron is pulled more strongly toward the other element and away from the hydrogen nucleus. Because the hydrogen atom is slightly positive (+), it will be attracted to neighboring negative partial charges (). When this happens, a weak interaction occurs between the + charge of the hydrogen atom of one molecule and the charge of the other molecule. This interaction is called a hydrogen bond. This type of bond is common; for example, the liquid nature of water is caused by the hydrogen bonds between water molecules (Figure 2.7). Hydrogen bonds give water the unique properties that sustain life. If it were not for hydrogen bonding, water would be a gas rather than a liquid at room temperature. Q: Breaking of weak bonds, which tend to form between positive and negative charges, does not require much what? Choices: - catalyzation - heat - time - energy A:
(A).
energy

Ans:bilateria
Answer the following question given this paragraph: Figure 11.7 Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. Q: Meiosis and mitosis are both preceded by one round of what? Choices: - internal fertilization - germination - cellular respiration - dna replication A:
dna replication
