Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.
Provide at least one example for each line of evidence.
Answer:
What Is the Evidence for Evolution? Darwin used multiple lines of evidence to support his theory of evolution by natural selection -- fossil evidence, biogeographical evidence, and anatomical evidence. Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. ... In humans, the tail is reduced to the tail bone.
Image result for Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.
Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

A. The cell for trial 2 with a lot of water
B. The cell for trial 3 with a moderate amount of water
C. The cell for trial 1 with a moderate amount of water
D. The cell for trial 2 with a little water
The correct option is B ; The cell for trial 3 with a moderate amount of water. Water is required by plants for photosynthesis. Water supplies ions such as protons and electrons.
What does moderate water mean?Exophytes are terrestrial plants that require just a minimal amount of water to flourish. These plants cannot live in extremely wet or extremely dry environments.
To conserve water, xerophytic plants have undergone many adaptations. To prevent transpiration losses, xerophytes' leaves are transformed into thorns. To absorb moisture from the earth, the roots are particularly deep-seated and deep-rooted. To produce photosynthesis and retain water, the stems are also green and fleshy.

What is the MOST likely reason for a 1000 kD protein to have just one band on its SDS Page gel pattern? The protein is made up of 2 subunits, 750 and 250 kD, respectively.
If a 1000 kD protein is composed of two subunits, each with a size of 750 kD and 250 kD, respectively, it is likely that the protein has just one band on its SDS-PAGE gel pattern because the two subunits are likely to have similar charges and molecular weights.
When proteins are separated by SDS-PAGE, they are first denatured and then charged based on their molecular weight. The denatured proteins are then separated based on their electrostatic interactions with the gel matrix and the pH of the buffer. Since the two subunits of the 1000 kD protein have similar molecular weights and charges, they are likely to have similar electrostatic interactions with the gel matrix and the buffer, and therefore, they may be separated by the same gel filtration and may appear as a single band in the gel.

All of the radioactive waste that is being subducted beneath with the tectonic plate could erupt from a volcano a few thousand million years later.
A volcano is a feature of the Earth's crust where molten rock is forced to the surface. When this molten rock is beneath the surface, it is referred to as magma, and when it erupts, or flows out, from a volcano, it is referred to as lava. Volcano emit gases, ash, and solid rock in addition to lava. Volcanoes come in a variety of shapes and sizes, but most are cone-shaped hills as well as mountains.
They can be found all over the world, forming ridges deep beneath the sea surface and mountains thousands of metres high. Around 1,900 volcanoes on Earth are considered active, which means they erupt on occasion and are likely to erupt again. Numerous others are dormant volcano that are not currently erupting but are expected to do so in the future. Others are thought to be extinct. Volcano are extremely powerful change agents.
