Answer:
One cell divides into two in a process called mitosis. Mitosis produces two genetically identical “daughter” cells from a single parent cell. Another type of cell division, meiosis, creates four daughter cells that are genetically distinct from one another and from the original parent cell. Only a few special cells can perform meiosis: those that will become eggs in females and sperm in males

In humans blood type A and B are equally dominant (codominant). Both types are dominant to type O. Aman with type AB blood marries a woman with type O blood, give the genotype and phenotype of all possible offsprings
Answers
Answer:
The correct answer would be -
Genotype: IAIO or IBIO
Phenotype: A Blood or B Blood
Explanation:
Blood group A and blood group B both are dominant over the blood group O, however, both A and B are codominant if present together and form the blood group AB.
The blood group of Aman is AB and If he marries the female with O blood group then possible blood group in offspring would be as follows:
gametes: Aman = IA and IB
woman = IO IO
then cross between:
IA IB
IO IAIO IBIO
IO IAIO IBIO
the genotype of this cross would be 50% chances of IAIO and 50% chances of IBIO and phenotype would be either Type A or type B.

What process creates stalagmites? Group of answer choices Rivers carrying rocks down a mountain Windblown sand shaping large rocks Minerals being deposited as water drips Glaciers pushing large rocks
Answers
Answer:
Minerals being deposited as water drips.
Explanation:
Stalagmites grow on the floor of a cave. The process that creates them starts with the filtration of rainwater drops through the rock picking gases and minerals, amongst these ones is calcite. When the drops containing these elements pass through the rock and are in contact with the air, a chemical reaction happens. As a consequence, the calcite precipitate on the floor of the cave. This process has to happen many times to form a stalagmite.

Yeast is added to bread dough before baking. After several minutes, the bread dough rises. Use your experiment to explain how respiration of yeast is important for the baking process.
Answers
Answer:
The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.
While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.
Make a yeast-air balloon to get a better idea of what yeast can do
Yeast is a unicellular fungus which undergoes anaerobic respiration to produce ethanol and carbon dioxide gas.
How does yeast fermentation work in bread-making?In a process known as fermentation, yeast consumes the sugar present in the dough to produce carbon dioxide and alcohol.The dough is kept in a warm area throughout the baking process.Fermentation occurs as a result of heat.However, if the temperature is too high, the yeast is killed during the cooking process.As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. The expansion of carbon dioxide during baking allows the bread to rise higher. During the bread-baking process, the alcohol created during fermentation evaporates.This is how yeast fermentation plays a vital role in the baking process.
