Answer:
Explanation:
They can contain DNA or RNA as their genetic material
Answer:
The answer is B.
Explanation:
A is incorrect because B is correct (plants are autotrophs).
C is incorrect because the first stage of cellular respiration is glycolysis, and the second is the Krebs cycle, neither of which require oxygen.
D is incorrect because cells take in oxygen to perform cellular respiration. Carbon dioxide is the product.
If a zebra mussel is discovered in a lake in Pennsylvania, then the ecologist would be worried because it is an invasive species. The zebra mussel is native to Ukraine and Russia, but if it has been found in Pennsylvania, than it means that it has been introduced in this area. As an invasive species, the zebra mussel can be very dangerous for the native species in the lake. The invasive species usually are more competitive for food sources than the native species, manage to reproduce quicker, bring in diseases, and the native species tend to not have defense mechanisms for them. This leads to rapid decline or even extinction in the native species, while the invasive spreads out quickly and takes over, resulting in dramatic change in the whole ecosystem.
Answer:
XYY, spermatogenesis.
Explanation:
Non disjunction may be defined as the phenomena in which the sister chromatids are unable to separate during the cell division. Non disjunction can occur in both meiosis and mitosis.
The determination of non disjunction is not possible. But the XYY condition in an individual might occur when the homologous chromosomes of Y are unable to separate during the process of spermatogenesis as Y chromosome is present in males only.
Thus, the correct answer is XYY and spermatogenesis
