Explanation:
Photosynthesis is a process during which energy from light is harvested and used to drive synthesis of organic carbohydrates from carbon dioxide and water, generating oxygen. Photosynthesis is the only way that radiant energy from the sun can be converted into organic molecules for plants and animals to consume.
When an animal eats, food stays in the stomach for a period of time. When a unicellular organism, such as Paramecium, takes in food, the food is contained in which organelle? Amino acids link together by peptide bonds to form proteins.
83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
Explanation:
Molarity or molar concentration is the number of moles of solute that can be dissolved in 1 L of a solution.
let us find the number of moles
n=C*V Concentration is 0.75M
Volume is 1000ml.
n= 0.75*1
n= 0.75
This means there are 0.75 moles of CaCl2 in 1000 ml of solution of .75M.
Molar mass of CaCl2 is = 40.08+ 2(35.5)
= 110.98 gms
Thus 1 MOLE OF CaCl2 weighs 110.98
so 0.75 moles will weigh 110.98*0.75
= 83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
Answer:
Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide
Explanation:
Answer:
The correct answer is - B. Non-disjunction during sperm formation resulted in her receiving no sex chromosome from her father and an X chromosome from her mother; she is XO.
Explanation:
In this case, the mother was a carrier of hemophilia and she transfers that mutant allele to her daughter and as the daughter did not get any sex chromosome from her father.
Therefore, mutant X expresses itself and she is hemophilic.
This X did not express in case, of her mother due to fact that it is a recessive allele and only expresses when both genes is the same state.
