What is a difference between prokaryotic and eukaryotic cells?

it takes light from the sun about three minutes to reach mercury how many hours does it take light from the sun to reach Neptune

Kazeer [188]

The time taken to reach the Neptune planet is 4.2 hours

<h3>What is the time taken?</h3>

We can see that the speed of light has the value of 6.7 * 10^8 miles per hour . We also know that the solar system is composed of the sun and the planets. The distance of the between the sun and mercury is 35,000,000 miles while the distance between the sun and Neptune is 2.8 x 10^9 miles.

This implies that the ratio of the distance from neptune to the sun and that of mercury to the sun is; 2.8 x 10^9 miles/3.5 * 10^7 miles hence Neptune is eight times farther from the sun than mercury.

The time taken for light to reach Neptune from the moon is;

Distance = 2.8 x 10^9 miles

Speed = 6.7 * 10^8

Time = 2.8 x 10^9 miles/6.7 * 10^8

= 4.2 hours

Missing parts;

Mercury is the closest planet to the Sun, with an average distance of 35,000,000

miles.

It takes light about 3 minutes to travel from the Sun to Mercury.

Neptune is the farthest, with an average distance of 2.8 x 10 to the power of 9 miles from the Sun.

How many times farther from the Sun is Neptune than Mercury?

A land developer and several ecologists are discussing how a parcel of private land should be developed with housing while savin

FromTheMoon [43]

Options for the question have not been provided. They are as follows:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.

C) The separate 1-hectare plots are less vulnerable to edge effects.

D) The large plot will create more inbreeding in many species.

Answer:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

Explanation:

In the given case, 20 hectares of land has been allocated to natural habitat. This means that natural flora and fauna will flourish here without any human interference. In this situation it is better to have an intact 20 hectares area at one side of the land, rather than having 20 separately spread out 1 hectare areas. This is because having one large piece of land at one side will reduce the edge effect.

Edges occur where two different habitats meet. While edges can be beneficial when it comes to natural habitats because the boundary habitat increases overall biodiversity, it can be detrimental when the edges are due to human settlements. It will be difficult to avoid human interference as the natural habitats are scattered among human settlements. Each individual plot will also get less area due to which it will be difficult for all the species to accommodate comfortably. Many animals can venture out in search of food which can be dangerous to both animals and humans. It is better to have a big separate land at one corner so that everyone can survive peacefully.

What is a stem cell research?

Ludmilka [50]

Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Commonly, stem cells come from two main sources: Embryos formed during the blastocyst phase of embryological development (embryonic stem cells) and. Adult tissue (adult stem cells).
