Can you answer this science question for me please?

Answer:

The reason why these stars seem so small compared to our Sun is:

B) Our Sun is much closer to Earth than the Seven Sisters.

Explanation:

The reason behind this is that the sun is at a distance of the earth of 0.000016004 light-years. While the seven stars are at a distance of 400 light-years. Making them so far away that their size is reduced because in physics object size is altered by the perspective of the watcher or observer. Meaning that a ball the size of a car can be seen by our eyes as small as a bean if it is at the proper distance.

Answer:

B

Explanation:

B makes the most sense of your answer choices

Answer:

A)

Explanation:

This is because the law of the conservation of energy states that energy can not be created or destroyed. This means that you can not get more energy than you put in, this could be from any energy store. In addition That also means that you will not be able to get less energy than you put in.

Although energy can not be created or destroyed some energy is lost to heat or friction, this would mean that the energy is not transferred to the idea store and so is lost to inefficiency . An example of this would be wind turbines, the wind would move the turbine using kinetic energy however some of the energy is lost to heat and friction

Answer:

The respiratory system has cells that produce MOCO OR MUCUS, which trap germs and dust. On their surface they have a large number of cellular structures called CILIAS, whose function is to spread mucus and direct it outwards. In the stomach, the digestive glands produce the STOMACH ACID, which, due to its extreme ACIDITY, attacks and destroys the PATHOGEN MICROORGANISMS that are introduced with food and drink.

Explanation:

In the respiratory and digestive apparatus there are two types of super specialized mucous upholstery, where the cellular world is challenged.

In the respiratory mucosa the production of mucus and the mobilization of the cilia are part of the innate response of the organism as well as the acidity that is generated in the upholstery and in the gastric tract.

Egg cell

The level of structural organization which best describes an egg is: A. a cell.

A cell can be defined as the fundamental (basic) structural, functional, and smallest unit of life, that is typically found in all living organisms such as animals.

The structure of an egg is similar to those of cells found in living organism, which are structurally layered with various cell organelles.

An egg shell is selectively permeable because it acts as an outer membrane just like in living cells to prevent unwanted materials from going into the egg.

In conclusion, the level of structural organization in animals cells can best be describe by using an egg.

Answer:

the biggest change to San Joaquin Valley ecosystems caused by humans in the past 150 years is the shortage of water in the river.

Explanation:

During 150 years, the San Joaquin Valley ecosystems was extremely damaged by the human activities such as building of dams and diversion of river. The San Joaquin Valley has a productive agriculture land due to availability of water. Due to building of dams, the amount of water in the river is decreases and also the population of many fish species decreases. this is because of the disturbance occurs in their natural habitat due to human activities.

Answer:

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.

Explanation:

Answer:

The earth is between the sun and the moon

Explanation:

The Moon is non luminous that is doesn't generate light by itself so it depends on light from the sun so when its path through which it taps light from the sun is totally covered it means the Earth is closer to the moon than the Sun so that the Earth gets all off its light leaving nothing for the Moon and in this case the Moon is thrown to total darkness.

Answer:

Explanation:

Both systems interact in the sense that digestive system involves the breaking down of complex food substances into simpler absorbable forms. These absorbable forms like glucose , amino acids etc are assimilated into the circulatory system through the hair-like structures in the small intestine (Villi, which has lots of blood capillaries) into the circulatory system. The circulatory system transports these food materials to different parts of the body where they are need for energy production and other metabolic activities.
