Answer:

option A, is the best technique for sampling the ocean floor

Explanation:

Ocean coring is a process in which sample of sea floor sediment is taken and studied to understand its composition. it is a common practice during the petroleum production from sea floor and hence is known as ocean sediment coring.

Usually a cylindrical sample is extracted beneath the sea floor by dropping a cylinder through the water. The sedimentary sample collected show the deposition of sediment (variation) with due course of time.

hence , option A is correct

Are amplitude and wavelength related
anyanavicka [17]

Answer:

Below! ;)

Explanation:

The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next. Wavelength is directly related to the frequency of a given wave form.

Hope this helps!

Look up viruses. Write a short summary of what they are and what they do.
vlabodo [156]

Answer:

Viruses are neither prokaryotes nor eukaryotes because they lack all of the characteristics of living things except for the ability to reproduce. They are considered parasitic because they cannot live or replicate without a living host. Viruses consist of genetic material (either DNA or RNA), a protein coat, and sometimes a lipid envelope surrounding the protein coat. They have no function except to reproduce.

True or false the typical X shaped chromosomes is the result of DNA replication​
hodyreva [135]

Answer:

True

Explanation:

Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.

When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.

Is the temperature profile in the thermosphere more like that of the troposphere or the stratosphere?
podryga [215]

The correct answer is: stratosphere.

This is because their temperatures are rising instead of decreasing.

There are 4 primary layers of the atmosphere on Earth:  

Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.

Stratosphere  (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.

Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer

Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.
