Answer:
To understand the physical change and chemical change, one needs to know what is physical properties and what is the chemical properties of a substance.
Physical property is characteristic or trait of a substance that can be observed without converting the substance to a new substance. If there is any type of change in these physical properties like changing the appearance or form of matter and does not make a new substance, takes place it is called physical change.
A chemical change is a change in the matter of a substance that creates one or more new substances. This type of change includes the formation, color, of a precipitate, change in texture, and many other changes.
Answer:
C. The rate of photosynthesis increases with an increase in carbon dioxide.
Explanation:
Photosynthesis, which is the process by which certain organisms obtain their food from the light provided by the sun, can be inhibited or promoted by certain factors. One of the reactants of the photosynthetic process is carbon dioxide (CO2), hence, an increase in the amount of carbon dioxide, increases the rate of photosynthesis.
According to this question, two areas with equal sunlight and available water are being described to have different levels or amounts of CO2. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. This means that Area 1 will undergo more photosynthetic activity than Area II.
Answer:
The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.
Explanation:
LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.
The answer is the mitochondria
