In an experiment, mendel grew 633 green pea plants with either wrinkled seed-coats (dominant) or smooth (recessive). if the ratio of the wrinkled seed-coat plants to the smooth seed-coat plants was 3: 1, how many smooth seed-coat plants did he grow? a) 158 b) 211 c) 633 d) 844

There are 158 smooth seed coat plants he grew.

Explanation:

Since we have given that

Total number of green pea plants with either wrinkled or smooth = 633

Ratio of wrinkled seed coat plants to the smooth seed coat plants = 3:1

So, Number of smooth seed cost plants that he grow is given by

Hence, there are 158 smooth seed coat plants he grew.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
