Question 7: What conclusions can you make about how a change in the condition of the ocean affects the different species in coral reefs?

The homo-logous mitochondrial sequences CTGTCCGAAG and CTGTCCGTCG suggest that species diverge from a common ancestor 660,000 years ago.

The mutation rate indicates the number of nucleotide differences between two homo-logous sequences that emerged in evolution in a given period of time.

In this case, the mutation rate is one nucleotide per 330,000 years and here we have two mutations (CTGTCCGAAG and CTGTCCGTCG), thereby it is expected that the sequences diverged 660,000 years ago.

In conclusion, the homo-logous mitochondrial sequences CTGTCCGAAG and CTGTCCGTCG suggest that species diverge from a common ancestor 660,000 years ago.

Answer:

The water cycle depicts the ongoing circulation of water inside the Earth and atmosphere. It is a complicated structure with several functions. Water vapor evaporates from liquid water, compresses to create clouds, and falls back to earth as rain and snow.

Explanation:

The water cycle is a cyclical process in which water circulates between the earth's atmosphere, seas, and surface via precipitation, drainage in lakes and rivers, and return to the earth's atmosphere by absorption and evaporation. Throughout respiration, organisms exhale carbon dioxide and water vapor, which evaporates back into the atmosphere.

The part of the vertebrae that transfers weight along the axis of the vertebral column is the:. vertebral body

The vertebral body serves as a weight-bearing part of a vertebra. The vertebral body is a thick and disc-shaped structure and forms the anterior portion of the vertebrae.

A vertebral body has rough inferior and superior surfaces. Being disc-shaped, the vertebral bodies of subsequent vertebrae are stacked upon each other and thereby, serve to carry the weight.

The sucrose moved in sink by active transport.

Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.

In this case, the sucrose moves from companion cells in sink elements by active transport. This reduces the water potential of the sink element  by osmosis, which increases the hydrostatic pressure.

Explanation:

Answer:

Explanation:

: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.

To describe a scientist as skeptical means that they question both existing ideas and new hypotheses.

The comparison of species based on common physical characteristics Thus, the correct option is D.

Cladistics is a method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.

Clades, which are collections of organisms made up of an ancestor species and its offspring, are also identified through cladistics.

A cladogram only displays one probable phylogeny for a collection of organisms. It can shed light on the process of evolution. A cladogram should not be viewed as a representation of genuine evolutionary processes, though. It may or may not depict what actually occurred. It merely illustrates what might have occurred.
