Answer:

1.The Sun, Earth and Moon are aligned with the Earth in the middle and the Moon furthest away from the Sun.

2.The Moon only partially covers the Sun during the eclipse.The Moon only partially covers the Sun during the eclipse.

3.Moon in perigee orbit; Moon moves a direct line between Sun and Earth; Moon in new moon phase.

4.The Earth's umbra fits inside the Moon creating an illuminated ring known as a annular eclipse.

The right answer to number four is

The Earth's umbra only cover a part of the Moon causing a circular shadow to pass across it.

A partial lunar eclipse happens when the Earth's umbra part moves across the Moon making a circular shadow across the Moon. An annular lunar eclipse is not possible because the Earth's umbra is always larger than surface of the Moon even if the orbits are in apogee.

Suppose that in another world, DNA does not undergo semiconservative replication, but instead a conservative mechanism is used.
Liono4ka [1.6K]

Answer:

c. ¼ heavy, ¾ light

Explanation:

DNA replication follows semi conservative model which means that both the strands separate during replication and the newly formed DNA molecule has one old and one new strand. If instead of semi conservative, conservative mechanism is used, old strands will not separate from each other and the two newly synthesised DNA strands will come together to form a DNA molecule.

Here the cells were first grown in heavy 15N medium so all the DNA molecules had 15N and thus were heavy. Then the cells were transferred to 14N medium where only lighter 14N were available for replication process.

In first generation, 14N DNA molecules were synthesised from 15N DNA molecules so 1/2 DNA molecules were 15N and other half were 14N. In the second generation, 14N molecules will give rise to new 14N molecules and 15N molecules will also give rise to 14N molecules hence 1/4 molecules will be 15N (heavy) and 3/4 will be 14N (light).

Answer:

Option a (Hit)

Explanation:

A research paper published in 1984 demonstrated that when we see similar results in our experiments of DNA bands we often observe hit classical theory.

jasenka [17]

Answer:

Incomplete dominance

Explanation:

The inheritance pattern described here is called incomplete dominance (sometimes also referred to as semi-dominance or partial dominance). This occurs when the dominant allele doesn't fully prevent the effects of the recessive allele from being expressed. This results in the trait of the offspring being equivalent to the mix of both alleles. If the rooster's feathers are black and the hen's are white, the chicks' will be grey.
