Correct Answer: B. organ

Correct Answer: A. Only internal processes control and impact the ecosystem.

Explanation

External process also affect the ecosystem. For example, climate is a very important external factor that will affect temperature and precipitation within the ecosystem.

Correct Answer: A. glucose

Explanation

Though the Benedict's and Fehling's tests are tests for sugars but the Fehling's test can only detect monosaccharides. So, though the sample gets result with the Benedict's test, the test only yields result with the Fehling's solution if it is a monosaccharide e.g glucose, fructose and galactose.

Correct Answer: C. Species

Correct Answer: B. 100%

Explanation

If a woman is colorblind, that means she has the nonworking gene on both X chromosomes. Since sons almost always get their only X chromosome from their mom, chances are they will be colorblind too

Correct Answer: A. 3

Correct Answer: C. producer

Correct Answer: D. Three of the answer choices are correct.

Explanation

Enzymes do not alter the equilibrium constant because enzymes are not consumed in the reaction. Hint: Write out the equation for the equilibrium constant and notice that there is no variable for enzymes. Enzymes are sensitive to temperature and pH, as high temperatures and very low pH can cause denaturation of an enzyme. Enzymes are only optimal at certain pH and temperature ranges.

Correct Answer: D) deserts

Explanation

Deserts would be the biome in which you would expect to have the shortest growing season. A biome is a large ecosystem that has similar environmental conditions such as temperature, precipitation, and plant and animal life. The growing season is the period of time in which the weather is warm enough and there is enough water for plants to grow. Deserts are known for being very dry and having extreme temperatures, with hot days and cold nights. They also have very little precipitation, which means there is not enough water to support plant growth all year round. Therefore, the growing season in deserts is usually very short. In contrast, tropical rainforests have a warm, humid climate with abundant rainfall, making it possible for plants to grow all year round. Guinea savannas and sudan savannas have a wet and dry season with enough rainfall to support plant growth for a longer period compared to deserts. Therefore, option D, deserts, is the correct answer

Correct Answer: D) There are few number of organisms at the start of a food chain

Explanation

This Biology question is asking which of the statements is inconsistent with the concept of trophic structure. Trophic structure refers to the feeding relationships between different organisms in an ecosystem, and it involves the transfer of energy and nutrients. The options given are A, B, C, and D. Option A states that at every feeding stage, some energy is wasted from the chain. This is a consistent statement with the concept of trophic structure because as energy is transferred from one trophic level to the next, some energy is always lost in the form of heat or other metabolic processes. Option B states that the nearer the organism to the beginning of a food chain, the greater the available energy of the organism. This is also a consistent statement because organisms at the beginning of a food chain, such as autotrophs, have access to more energy from the sun or other sources than organisms higher up in the food chain. Option C states that the first trophic level is occupied by the autotrophs. This is a consistent statement because autotrophs are the primary producers in an ecosystem and are therefore at the first trophic level. Option D, which is the correct answer, states that there are few numbers of organisms at the start of a food chain. This statement is inconsistent with the concept of trophic structure because the start of a food chain usually has the highest number of organisms, such as plants, which are eaten by herbivores, which in turn are eaten by predators. In summary, all the options except option D are consistent with the concept of trophic structure, which is the feeding relationships and transfer of energy and nutrients in an ecosystem.
