A baby isn't considered a fetus until about 8 to 9 weeks after
conception. During those first weeks, the baby is considered as the
embryo. The embryo is the development of the pregnancy until about 9
weeks, it will then turn into a fetus.
The contamination cleanup strategy called bioremediation—using naturally occurring or genetically modified microbes to clean up our messes—is gaining steam, as scientists devise new ways to use bugs against mercury, oil spills, radioactive waste and more.
Vesicles form naturally during the process of secretion(exocytosis), uptake (phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes.
Answer:
C
Explanation:
meiosis made 4 haploid daughter cells, with 1 round of dna replicates and followed by 4 division of haploid daughter cells
Answer:
The correct answer is - temperature, pH, substrate concentration.
Explanation:
Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.
Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.
pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.
Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.
