Birds have feathers (bats and insects can fly too)
Answer:
The difference between C3, C4, and CAM photosynthesis is the way plants extract carbon dioxide from sunlight. This depends largely on the plant's habitat. C3 photosynthesis produces three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
CAM plants open their stomata at night, C3, and C4 open during the day.
Explanation:
Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
- The researcher has total control over the crosses.
- Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
- Pea plants may be examined for a greater series of generations than cats or other animals.
- Because plant genetics is not overly complicated, several traits may be investigated at the same period.
As a result, the primary factors why Megor Grendel's experiments are not well-known:
- The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
- Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
- Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.
As a result, it is impossible to draw any conclusions from them.
Answer:
Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Complete the paragraph by using the drop-down menus.
In this lab, you determined the relative ages of rock layers using the principles of relative dating. The
✔ law of superposition
says that a rock layer found closer to Earth’s surface is
✔ younger than
a rock layer that is deeper in Earth’s surface. The
✔ principle of cross-cutting relationships
states that intrusions are
✔ younger than
the rock layer they cut across. You also determined the absolute ages of rock layers using a
✔ mass spectrometer
. The data you gathered helped you identify an unknown fossil.
