Answer: c. the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Explanation:

The wavelength is simply the distance that takes place between two successive troughs fir a particular wave. It is calculated as:

Velocity / Frequency.

From the statement given, the option that is accurate is that the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Effectus [21]

Answer:

One band of light density and one band of heavy density.

Explanation:

According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.

Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).

What does cladistic analysis compare
viktelen [127]

Answer:

Cladistic analysis compares the shared and shared derived characteristics of organisms which are thought to be of same ancestral origin.

Explanation:

  • The branch of sytematics concerned with inferring phylogeny is termed as cladistics.
  • It determines the branching pattern of evolution.
  • It decribes the sequence of branching of ancestral lines.
  • The basic idea behind cladistics is that the members of a group share common evolutionary history, and are closely related, more so to members of the same group than to other organisms.

The negative impact of youth risk behavior considers the risks to youth health and the protective behaviors of health including smoking, drinking<span>, </span>drug use<span>, diet and physical activity. Depending upon one's social circumstance including the location of upbringing and access to education, the risk to health would increase, this could be affected by economic factors, with negative health impact increasing with the less access to resources. This directly impacts on the physical and mental well-being of an individual, with bad diet and lack of physical activity limiting a person's potential in the socioeconomic sphere and confidence and health.</span>
