O D. Aphanite

Answers

Answer:

D. Aphanite

Explanation:

A.P.E.X

An invasive igneous body is aphanite. Thus, the correct option is D.

What are Aphanite rocks?

Aphanite's are igneous rocks that were formed by rapid cooling in a volcanic or hypabyssal setting and are so finely grained that their individual mineral crystals cannot be seen with the unaided eye.

Very fine-grained, crystalline fabrics called aphanitic minerals are created when a magma solidifies in reaction to an exceptionally rapid loss of heat and dissolved gases. They are characterized by grains that are too small to be recognized without a petrological microscope.

Large crystals are known to be present in certain specific igneous rocks. The crystals in this type of rock are approximately the same size. Compared to aphanitic rock, which is known to have rocks with finer grain sizes.

So, the correct option is D.

An expiriment was done to determine if the rate at wich a patato cooked depended on the temperature of water in which it was boild. What are the independent and dependent variable??​

Answers

Answer:

The independent variable  is  the  potato   and dependent variable  will  be  the  temperature

Explanation:

When  this  experiment  is  done  it  consider  about  the  boiling  rate  of  the  temperature  which  it  helps  to  cook  the  potato.  in  other  words  when  you  do  this  experiment  you  will  try  different  temperature  levels  on  the  same  type  of  vegetable  which  is  a  potato.  so  the  variable  called  temperature  will  be  dependent  because  its  the  variable  that  we  change.  and  the  variable  called  potato  will  be  the  independent.

What happens when muscles in the frogs body wall contract?

Answers

With the nares open, the frog contracts muscles in the floor of its mouth to drop the floor of the mouth down. This enlarges the buccal cavity. Since the area is larger, the pressure inside the mouth drops. Air rushes through the nares into the buccal cavity equalizing the pressure inside and outside the frog.

Jason joined a group that would work towards solving the workplace safety issues in his organization. Arrange Jason’s actions according to the stages of development of his group.

Answers

Answer:

- Jason asked his fellow group members  about their hobbies and interests .

- Jason and another member disagree on  what their respective roles should be in  the group.

- Jason resolved his differences with the  other group members .

- Jason began working with the group  members as a complete unit .

Explanation:

The correct order of Jason's actions in the stages of the development of his group would be as mentioned above. After the first step of the formation of the group, the next step is 'storming' in which the ideas are generated. Thus, Jason asks the group members regarding their interests and hobbies as it assists in the generation of effective ideas for problem-solving. The next step would be 'norming' in which the conflicts would arise due to disagreement regarding the respective roles of group members. Then, Jason as a team member would resolve the differences among the team members to reach a common solution. After everyone agrees upon the same idea, Jason can pursue working with the group as a complete unit. These stages are crucial for the effective development of the group and achieve desired results through cooperation and teamwork.

Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.

Answers

Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

*mark as Brainliest ty*

Answer:

It changes the amount of friction there is. There is more friction where water is shallow, and less friction where water is not as shallow. The friction has the power to cause erosion as it causes movement of water.

Anna applies a force of 84n Nto lift her baby nephew 2.0 m. How much work
does Anna do? Answer


Answers

Answer:

168 J

Explanation:

Work can be calculated using the following formula.

w=f*d

where w is work, f is force, and d is distance.

Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.

f=84 N

d=2 m

Substitute these variables into the formula.

w=84 N* 2 m

Multiply

w=168 N-m

A N-m is the same as a Joule, or J.

w= 168 Joules

Anna does 168 Joules of work.

What do you mean by biome?

A biome is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate.

A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

The atmospheric temperature decreases when snow starts melting because the snow

Answers

Answer:

The atmospheric temperature decreases when snow starts melting because the snow  absorbs thermal energy from the atmosphere to melt.

Explanation:

The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

People in Space by R. Howard Cosmonaut Yuri Gagarin's 108-minute orbit of the Earth on April 12, 1961, made Russia the first nation to both put a human in space, and into orbit. On his experience in space, Gagarin reported that he saw objects floating in the cabin and that he himself was unable to remain seated in his chair, but was hanging in the air. This effect is called weightlessness, which occurs due to the zero gravity conditions in space. John Glenn was the first American to orbit the Earth and was put into orbit in February 1962. He orbited the earth three times before landing successfully. Other astronauts including Alan Shepard, Jr., Scott Carpenter, and Virgil Grissom followed John Glenn to become the first set of Americans to make space flights. Later in 1962, the American astronaut Walter M. Schirra Jr. , and Russian cosmonauts Andrian G. Nikolayev and Pavel R. Popovich were launched to orbit the earth. The first woman in space was a Russian, Valentina Tereshkova. She made forty-eight orbits of the earth before returning safely. On May 25, 1961, the race to reach the moon was made public when President John F. Kennedy of the United States declared, "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. " On July 16, 1969, the Apollo 11 moon mission was launched. Four days later, on July 20, the great dream was realized when Neil Armstrong became the first human to set foot on the moon. Michael Collins and Edwin Aldrin were with Armstrong, and they became the succeeding humans to step on the moon.According to MLA guidelines, which of the following best summarizes what is written about moon landing in this passage?A.)
