Answer:
DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans
Answer:
The soils with earthworms will show a faster rate of ammonification
Explanation:
Originally, the nitrogen released by organisms when they die (or excrete waste products) is organic nitrogen, e.i., amino acids and nitrogenous bases in DNA. Ammonification is the property that decomposer organisms have to mineralize organic nitrogen in order to produce inorganic nitrogen in the form of ammonium (NH4+). In agroecosystems, earthworm activity can increase the ammonification rate. For example, <em>Lumbricus terrestris</em> is an invasive earthworm (which is native to Europe) that has been shown to increase both ammonification and nitrification (nitrate production) rates in the soil of different ecosystems.
Answer:
The correct answer is option A.
Explanation:
The lymph node is a small bean-like structure that filters substances that move through the lymphatic pathway with the lymphatic fluid. Lymph nodes are present on different site in the human body. They contain white blood cells that soldiers of the human immune system and fight with infection and pathogens.
Immune system cell that is B and T cells both, not just located in the cortex only but medulla of lymph nodes.
Thus, the correct answer is option A.
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
