A tiltmeter is a volcanic monitoring tool that measures _____.

Answers

A tiltmeter is a volcanic monitoring tool that measures ground swelling.

A tiltmeter is an instrument that is used to determine if the elevation of the earth crust has changed. Tiltmeters measures the angle of an object with regards to gravity. Tiltmeters are highly used in monitoring dams, volcanoes, hydraulic fractures and landslides.

A tiltmeter monitors the earth's crust to determine if any uplift is occuring. Simply put, it measures the crust to see if the elevation has changed.

How does energy acquisition in the deep sea differ from energy acquisition near the ocean’s surface?

Answers

I think the correct answer from the choices listed above is option C. The energy acquisition in the deep sea differ from energy acquisition near the ocean’s surface by the fact that organisms in the deep sea do not have direct access to sunlight. hope this helps!!!

Unlike gradualism, punctuated equilibrium involvesa. a slow change in evolution over time.
b. stable periods of change interrupted by rapidly occurring change.
c. species that are said to be in equilibrium.
d. a steady change in evolution over time.

Answers

The correct answer is option b. stable periods of change interrupted by rapidly occurring change.

The punctuated equilibrium is referred to a evolutionary pattern, in which the organism changes rapidly in order to survive the changing environment and remain unchanged for a very long period of time. hence, in this case, a stable period of change is followed by a rapidly changing phase.

The gradualism refers to the slow and steady changes, which helps the organism to adapt the changing environment.

d. a steady change in evolution over time.

Unlike gradualism, is the process by which a certain specie or creature undergo changes and variations in a limited and solely focusedly confined in long period of time.

The first step in sensation for some sensory systems is the __________, which modify incoming stimuli

Answers

The first step in sensation is reception. It makes use of accessory structures or sensory receptors which modify or respond to incoming stimuli. A stimuli is defined as a detectable change inside or outside an environment. Reception is the activation of these accessory structures by a stimuli. Examples of a stimuli are changes in temperature, pain, light, loud sound, etc.

Answer:

Accessory structures or B

The cellular process of creating two new DNA molecules from one original copy is called replication. Which statement is the BEST description of this process? A) DNA opens up and RNA copies it. B) DNA opens up and completely unwinds to make two new molecules. C) DNA opens up and each strand is used as a template for a new strand. D) RNA opens up the DNA and uses each strand as a template for a new strand.

Answers

The correct answer is C.

In replication, an initiator protein unwinds a short length of the DNA double helix. Next, an enzyme known as helicase attaches itself to the unwound helix and begins to break the hydrogen bonds between the base pairs of the two DNA strands, thereby pulling them apart to form a Y shape called a replication fork. The two separated strands act as templates for making the new strands of DNA.

An enzyme DNA polymerase then binds to one of the strands called the leading strand because it is the one oriented in the 3' 5' direction (towards the replication fork) and begins walking along it adding new complementary bases to it. After the new strand is proof read by DNA Polymerase, it is sealed up by DNA ligase, an enzyme specific for this task.

The other strand called the lagging strand because it faces way from the from the replication fork in 5' 3' direction also undergoes the same process with a few minor differences to produce the other new complementary strand.

The Correct answer is C: DNA opens up and each stand is used as template for a new strand
