Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
The correct answer is From east to west
June 21st represents the sun in the sky at noon for the northern hemisphere.
Explanation:
The summer is hotter because the sun's part is higher in the sky. This reason makes the days longer and makes summer sun more intense.
The summer solstice for northern hemisphere occurs in june 21. On this day the sun's position at noon is higher in altitude of the year.
In the summer season , The north pole is tilted towards the sun and this causes the sun's part to be higher in the sky causing the northern hemisphere to receive more light and heat.
Answer:
Mitochondria is known as the powerhouse of the cell as it provides energy to the cell for performing different functions.
If a toxin causes pore in the inner membrane of the mitochondria and increases the permeability of the mitochondrial membranes. The permeability of mitochondrial membranes leads to mitochondrial swelling and causes cell death through necrosis and apoptosis.
Answer:
Mendel's first law of Segregation of Gametes says that "The alleles of a given locus segregate into separate gametes during meiosis"
Explanation:
The two alleles of a gene pair separate from each other during the process of meiosis and each gamete have an equal probability of producing either allele of the gene.
One parent pea plant is homozygous for inflated pods and green (suppose GGII) which is dominant in nature. Another parent pea plant is homozygous for deflated pods and yellow (suppose ggii) which is recessive in nature.
•) Then both the homozygous parent plants (GGII and ggii) which are dominated and recessive are crossed.
•) The gametes which will be obtained are GI and gi.
•) The resultant progeny is heterozygous with dominant traits GgIi.
