Answer:
The correct answer is 128 cells
Explanation:
Given: 1 complete cell cycle takes 24 hours. It means 1 plant cell divides into 2 cells in 24 hours. Thus, number of hours in one week will be:
24 x 7 days = 168 hours, if one cell cycle takes 24 hours, then in 168 hours there will be 7 cell cycles.
So, first cell cycle will results into 2 cells and both these cells will divide and will results into 4 cells and then after third division it will 8 cells and so on..
Therefore, at the end of 7th division there will be 128 cells.
Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.
the last phosphate bond is broken.
that's called a macroergic bond between the 3rd and 2nd phosphate groups
Answer:
The correct answer is a. Potassium hydroxide (KOH) preparations
Explanation:
Potassium hydroxide preparation is a simple test which is carried to identify the fungal infection invaded in skin, nails, vagina, etc. KOH degrade the keratin or mucous present on sample and clears the background which makes fungal cell more visible under the microscope.
In this method sample from infected area is collected and placed in the center of the slide then a drop of KOH is added on it. After this coverslip is put on the sample and the slide is heated gently to increase the reaction rate of KOH. Then the slide containing fungus is examined under the slide. KOH test is used for both yeast and molds. So the right answer is a.
Answer:
1. all different lives in 1 area
2.supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
3.heat differences between the forest and the tundra are the climates, animals and plants. The tundra's climate is very cold while the forest is warmer and the tundra receives little sunlight whereas the forest receive direct and constant sunlight. The animals living in the tundra includes the arctic fox, snowy owl,caribou,ermine and polar bear and some tropical forest animals are the howler monkeys,sloths,jaguars,parrots and toucans. There are only a few plants that grow in the tundra. Some of them are the arctic moss, arctic willow, bearberry and pasque flower. These are the differences between the tropical forest and the tundra.
