Answer the following question given this paragraph: Roots are covered with thin-walled dermal cells and tiny root hairs. These features are well suited to absorb water and dissolved minerals from the soil. Q: Well suited to absorb water and dissolved minerals from the soil, thin-walled dermal cells and tiny hairs cover what basic plant structures? Choices: - leaves - flowers - stems - roots A:
roots

Answer the following question given this paragraph: Biology - The Life Science Internal functions are coordinated and regulated so that the internal environment of a living thing is relatively constant, referred to as homeostasis10 . Living things are organized in the microscopic level from atoms up to cells11 . Atoms are arranged into molecules, then into macromolecules12 , which make up organelles13 , which work together to form cells. Beyond this, cells are organized in higher levels to form entire multicellular organisms. Cells together form tissues14 , which make up organs, which are part of organ systems, which work together to form an entire organism. Of course, beyond this, organisms form populations which make up parts of an ecosystem. All of the Earth's ecosystems together form the diverse environment that is the earth. Example:sub atoms, atoms, molecules, cells, tissues, organs, organ systems, organisms, population, community, eco systems. Q: Internal functions are coordinated and regulated so that the internal environment of a living thing is relatively constant, referred to as what? Choices: - stabilizer - hypothesis - homogenesis - homeostasis A:
(Answer)
homeostasis
Ques: Answer the following question given this paragraph: Volume measures the amount of space that a substance or an object takes up. The basic SI unit for volume is the cubic meter (m 3 ). Q: What is a measure of the amount of space a substance or an object takes up? Choices: - speed - density - mass - volume A:
Ans: volume

Answer the following question given this paragraph: Myoglobin, a protein that stores oxygen in muscle cells, has been purified from a number of organisms. The protein from a sperm whale is composed of 153 amino acid units. What is the minimum number of nucleotides that must be present in the mRNA that codes for this protein?. Q: Which protein, that stores oxygen in muscle cells, has been purified from a number of organisms? Choices: - melanin - potassium - iodine - myoglobin A:
(A).
myoglobin
Ques:Answer the following question given this paragraph: One major factor that limits the length of food chains is energy. Energy is lost as heat between each trophic level due to the second law of thermodynamics. Thus, after a limited number of trophic energy transfers, the amount of energy remaining in the food chain may not be great enough to support viable populations at yet a higher trophic level. The loss of energy between trophic levels is illustrated by the pioneering studies of Howard T. Odum in the Silver Springs, Florida, ecosystem in the 1940s (Figure 46.5). The primary producers generated 20,819 kcal/m2/yr (kilocalories per square meter per year), the primary consumers generated 3368 kcal/m2/yr, the secondary consumers generated 383 kcal/m2/yr, and the tertiary consumers only generated 21 kcal/m2/yr. Thus, there is little energy remaining for another level of consumers in this ecosystem. Q: Energy is lost as heat between each trophic level due to the second law of what? Choices: - reactions - particles - chemistry - thermodynamics A:

Ans:thermodynamics
Ques: Answer the following question given this paragraph: In all types of mechanical waves, energy moves from one place to another while the media carrying the wave only vibrates back and forth in position. One type of mechanical wave is the transverse wave . In the case of transverse waves, the movement of the medium is perpendicular to the direction of the energy movement. Q: In the case of transverse waves, the movement of the medium is perpendicular to the direction of the what? Choices: - friction movement - pressure movement - fuel movement - energy movement A:
Ans:
energy movement
