What is a vein in rock?

Answers

Answer 1

Answer:

Vein, in geology, ore body that is disseminated within definite boundaries in unwanted rock or minerals (gangue). The term, as used by geologists, is nearly synonymous with the term lode, as used by miners. There are two distinct types: fissure veins and ladder veins.

Explanation:

What Is A Vein In Rock?
Answer 2

Material deposits known as geological veins are created when an existing rock fracture is filled with a new mineral.

How rock veins are formed?

   

They are fascinating to planetary scientists because they frequently reveal information about historical water flow. For instance, a lot of rocks have natural pores.

A vein in geology is a distinctive sheet-like body of mineral crystals embedded into a rock. When precipitation occurs, mineral components that are transported by an aqueous solution within the rock mass are deposited as veins.  

Therefore, it is thought that aqueous solutions carrying different elements migrate through rock fissures and deposit their load onto the fissure walls when vein deposits occur, rising water that is hot.

Why do you think ANIMAL CELLS are able to survive without the types of cell walls that are present in nearly every other group of organisms? Provide 3 answers.

Answers

Answer:

They survive because these cells need a high permeability to be able to maintain the internal cellular balance in relation to the external environment that surrounds them, and this is due to their high energy demand, their multi-complex and multiple functions, and the capacity for constant homeostasis with the environment. that surrounds them.

Explanation:

In addition, some cells need to transmit signals, second messengers or even to fulfill a function to exchange compounds for their transmembrane, this is what makes the human system together with other systems of other animals is extremely open and is in constant energetic exchange, in addition to Unlike plant cells, plant cells are under an autonomous regime, they do not need to take energy from the environment but they manufacture it themselves, and it fulfills a great function that is to provide structure and support, the wall they have is what gives it the ability to fulfill these two functions.

Also if you make up rhymes or saying for things you are more likely to remember them. If you are artistic then draw pictures to help you remember certain things. Also peppermint helps you remember things. Lastly study before you go to bed and get at least 8 hours of sleep before the test.

B is the answer you are looking for

Answer:

When ground water reaches the surface it can form lakes or rivers.

Explanation:

Groundwater in valleys is often pushed under pressure by rainwater that falls on the nearby highlands. If the water table reaches the surface, a lake, a river, or a spring is formed. A spring in desert country is surrounded by plants that take advantage of the water supply, forming an oasis. Water now coming to the surface at oases in the Sahara Desert came from rain that fell on hills near the desert during the Middle Ages--eight hundred to one thousand years ago.

The light-dependent reaction

          The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.

What is Photosynthesis ?

           Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. Despite the fact that various species undertake photosynthesis in different ways, the process always starts when proteins called reaction centres that contain green chlorophyll absorb energy from light. Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.

         When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. Similar to this, plants use ATP molecules to store the energy they obtain from light during photosynthesis.

          In addition to converting ADP to ATP, photosynthetic processes are used by plants to absorb, process, and store solar energy. Animals convert ADP to ATP, which can subsequently be utilised to drive essential development and cell maintenance, using the energy supplied from the breakdown of glucose and other molecules.

           Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.

What arguments would you use to persuade the alien visitor that cars are not alive?

Answers

Answer:

Organisms need 6 things to be considered living which are, responsiveness to the environment, the ability to reproduce, having a metabolism, being able to breathe, maintaining homeostasis, being able to pass down traits, and made of cells. Cars, do not have the ability to reproduce, do not maintain homeostasis, cannot pass down traits, do not have a metabolism, etc... a living being needs to fit all of the criteria to be considered living. In this case, cars do not fit the criteria.

Knowing this, you would tell the alien about the 6 things needed to be considered a living being. After that, you would tell the criteria that the car does not fit which would then explain how a car is in fact, not a living being.
