Answer:

The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.

Below I list and describe some careers for Earth Science.

Mineralogy. This is has to do with the scientific research of minerals, which includes their physical properties, chemical composition, internal crystal structure, and occurrence and distribution in nature.

Soil Science. This is the science that has to do with soils as a natural resource on Earth, which includes the formation soil, classification, mapping, physical, chemical, biological, and fertility properties of soils.

Paleontology. This is the study of life prior to the modern world, basically discovering ancient fossils and structures that tell us how life used to be in the far past, going back to the era where dinosaurs still existed on Earth.

Answer:

A point mutation affects a single base pair. A point mutation may cause a silent mutation if the mRNA codon codes for the same amino acid, a missense mutation if the mRNA codon codes for a different amino acid, or a nonsense mutation if the mRNA codon becomes a stop codon

A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.

Explanation: hope this helps;0

All point mutations will result in a missense mutation. The statement is false. This is because a point mutation can result into silent mutation, a missense mutation, or a nonsense mutation.

A point mutation affects a single base pair in the DNA sequence. A point mutation may result into a silent mutation if the altered mRNA codon encodes for the same amino acid, a missense mutation if the altered mRNA codon encodes for a different amino acid, or a nonsense mutation if the altered mRNA codon becomes a stop codon.

A missense mutation is a mistake in the DNA sequence which results in the synthesis of wrong amino acids which are being incorporated into a protein molecule because of the change, that a single DNA sequence change results in a different amino acid synthesis which the ribosome recognizes.

Answer:

Scanning electron microscope.

Explanation:

We can answer this question by process of elimination.

A dissection and compound light microscope have too small magnification for this question. Transmission electron microscopes allow the electrons to pass through the subject, visualizing the inside, while scanning electron microscopes capture the exterior (or as the problem worded it, the surface). Therefore, scanning electron is the right answer.

Answer:

'fossil' fuel sources

Explanation:

disadvantages include global warming, climate change and pollution

One disadvantage of hydroelectric power is that the electricity used to pump water may have come from Fossil fuel sources.

Hydropower, or water power, is the process of using falling or swiftly moving water to generate energy or drive machinery. This is accomplished by generating electricity from a water source's gravitational potential or kinetic energy. A means of producing sustainable energy is hydropower.

Water flow and quality may be affected by hydropower. Low dissolved oxygen levels in the water, which can be caused by hydropower plants and are hazardous to riparian (riverbank) habitats, are a problem that is fixed using a variety of aeration techniques that oxygenate the water.
