Lunar phases occur when the Moon appears to change shape as seen from Earth. What causes different phases of the Moon? Select one:
a. the tilt of the axis of Earth
b. the shadow of Earth falls on the Moon
c. the alignment of the Sun, Moon, and Earth in a straight line
d. the amount of the sunlit side of the Moon that faces Earth

Answers

Answer 1

Answer:

Lunar phases are visible according to the amount of sunlit side of the moon facing the earth. So the correct option is D.

Why are lunar phases formed?

The moon does not produce any light of its own and only reflects the light falling on it from the sun. The sunlight hits all the sides of the moon but we can only see it when it falls on the side, or the part of the side visible to us.

So, when sunlight hits the far side of the moon, it is called a new moon. The far side is the side of the moon not visible from earth. Therefore we are unable to see the moon when this happens.

But when sunlight falls and reflects from the near side of the moon, a bright round structure of the moon is visible from the earth. This is called full moon.

Other than that there is the waning crescent, waxing crescent, first quarter, waxing gibbous, waning gibbous and third quarter. All these depend on the side of the moon visible from the earth when sunlight falls on it.

When, during the course of the revolution, the earth comes between the sun and moon blocking sunlight on the moon, a lunar eclipse occurs.

Therefore, the correct option is D.

Within eukaryotic cells, there is an intricate network of _______ with unique functions.

Answers

Within eukaryotic cells, there is a network of organelles which have unique functions.
An organelle is termed as a specialized subunit within a cell which has specific functions and their functions are very vital for a cell to live. Organelles can be identified by microscopy and purified by cell fractionation.
In eukaryotic cells has many types of organelles. Larger organelles which are found in eukaryotic cells are visible with the light microscope, for example, vacuole and nucleus.
Some of the major eukaryotic organelles include plastid, endoplasmic reticulum, flagellum, mitochondrion, vacuole, nucleus and Golgi apparatus

Within eukaryotic cells, there is a network of organelles that have unique functions.

Further Explanation:

An ecosystem is made up of mainly two kinds of cells:

Eukaryotes cells: They mainly consist of a group of animals, fungi, and plants.
Prokaryotes cells: They mainly consist of bacteria and archaea.

Some main features of eukaryotic cells are:

They consist of membrane-bound organelles and nucleus
The DNA of a eukaryotic cell is present inside the nucleus of a cell.
The nucleus that is surrounded by a membrane is referred to as a true nucleus.

Specialized sections present inside the eukaryotic cells are called organelles. Different functions are performed by different organelles inside the cell. They are the specialized unit in eukaryotes and play several important functions for a cell to survive. Organelles can easily visualize by a microscope and can isolate by cell fractionation method.

The eukaryotic cell has a different type of organelle and plays a specific function for example

Endoplasmic reticulum: They help in synthesizing protein and lipids.
Mitochondrion: It produces energy and is called the powerhouse of the cell.
Golgi apparatus: It helps in packaging and modification of a protein.
Chloroplast: It helps in photosynthesis.
Nucleus: It contains the genetic material of a cell.
Vacuole: It contains cell sap.

What is the dominant gas in the atmosphere that forms clouds is?

Answers

The answer is water vapor.

Water is presented in the form of tiny gas particles called water vapor in the atmosphere. The clouds are formed when this invisible water vapor in the atmosphere condenses onto microscopic particles (dust, dirt,...).

A scientist conducting an experiment quickly saw that she was not getting the results she expected. Instead of continuing to collect data, she went back to redesign the experiment until the data came out the way that the hypothesis predicted. The scientist’s work did not follow the scientific method. Which statement best explains why?

Answers

Answer:

The following is the correct answer: The scientist's work did not follow the scientific method as she failed to look at the data objectively by trying to get a desired result.

Explanation:

The scientific method is an empirical method of acquiring knowledge that is universally used within the scientific community. It involves careful observation, and the application of rigorous steps and a general notion of skepticism about everything that is being observed. The main objective of the scientific method is to obtain the most truth to reality and objective results possible. When the scientist decided to start with her experiment all over again because the results she was getting were not the ones she was expecting, she failed to properly follow the scientific method, as she was no longer looking for objective results but rather the ones she previously desired to get.

When her experiment didn't work, she changed her procedure instead of her hypothesis.

Hope I helped! :)
