Answer the following question given this paragraph: Q: What is the term for the most abundant species in a community, characterized by high competitive abilities? Choices: - keystone species - merging species - carnivores - dominant species A:
dominant species
Answer the following question given this paragraph: Most amphibians live in fresh water, not salt water. Their habitats can include areas close to springs, streams, rivers, lakes, swamps and ponds. They can be found in moist areas in forests, meadows and marshes. Amphibians can be found almost anywhere there is a source of fresh water. Although there are no true saltwater amphibians, a few can live in brackish (slightly salty) water. Some species do not need any water at all, and several species have also adapted to live in drier environments. Most amphibians still need water to lay their eggs. Q: Where do most amphibians live, salt water or fresh water? Choices: - aquariums - deserts - saltwater - fresh water A:
fresh water
Q: Answer the following question given this paragraph: Stratus clouds occur low in the troposphere. They form in layers that spread horizontally and may cover the entire sky like a thick blanket. Stratus clouds that produce precipitation are called nimbostratus. The prefix nimbo- means "rain. ". Q: Where do stratus clouds occur in the troposphere? Choices: - mid to high region - high - mid-region - low A:
A: low
Question: Answer the following question given this paragraph: Most chromosomal disorders involve the sex chromosomes. Can you guess why? The X and Y chromosomes are very different in size. The X is much larger than the Y. This difference in size creates problems. It increases the chances that the two chromosomes will fail to separate properly during meiosis. Q: Most chromosomal disorders involve which chromosomes? Choices: - autosomes - ribosomes - protosomes - sex chromosomes A:
Answer: sex chromosomes
*Question*
Answer the following question given this paragraph: Sexual reproduction occurs in a cycle. Diploid parents produce haploid gametes that unite and develop into diploid adults, which repeat the cycle. This series of life stages and events that a sexually reproducing organism goes through is called its life cycle . Sexually reproducing organisms can have different types of life cycles. Three are represented in Figure below and described following sections. Q: What is the term for the series of life stages and events that a sexually reproducing organism goes through? Choices: - society cycle - existence - age - life cycle A:
**Answer**
life cycle
Q: Answer the following question given this paragraph: Homeostasis refers to the balance, or equilibrium, within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is referred to as homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the normal proportions of all internal substances. This involves continual adjustments in transport of substances across the cell membrane. Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in the cell transport (passive and active transport) concepts all play an important role in homeostatic regulation. Q: What term means the adjusting of systems within a cell in order to restore balance or maintain equilibrium? Choices: - systemic regulation - aftertouch regulation - gaseous regulation - homeostatic regulation A:
A: homeostatic regulation
