Compaction is most significant as a lithification process for sedimentary rocks composed of sand-sized particles.
a. true
b. false

Answers

Answer 1

Answer:

False

Explanation:

Lithification is defined as the summation of compaction and cementation. Finer materials undergo compaction due to the force exerted by the overlying sediment layers. Clay particles (diameter < 0.002mm) undergo more compaction because they are finest in terms of size whereas silt (diameter 0.002-0.06mm) and sand-size sediments (0.06-2mm) are relatively coarser..

So, compaction is relatively a more significant process for clay particles than the silt and sand-sized particles.

Hence the given statement is false.

Answer 2

Compaction is NOT the most significant process as a lithification process for sedimentary rocks composed of sand-sized particles.

Sedimentary rocks are as a result of compaction, lithification  and cementation.

Further ExplanationRock A rock is a naturally occurring substances that is a solid mixture of one or more minerals together with organic matter.Rocks are classified based on the chemical composition, texture and the way they are formed.  Sedimentary rocks Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. The process involved include compaction and cementation of sediments.These sediments includes; pebbles, shells, sand and other material fragments.  The sediments accumulates in layers and then harden into rocks over a period of time.Examples of sedimentary rocks include; limestone and conglomerate

Lithification, cementation and compaction

Lithification is the process by which sediments combine to form sedimentary rocks. Compaction involves the consolidation of sediments due to the intense pressure and weight of the overlying deposits. Compaction takes place when sediments get buried.Cementation is the process through which dissolved minerals crystallize and glue grains of sediments together.Other types of rocks Metamorphic rocksThese are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.Examples of metamorphic rocks are marble and gneissIgneous rocks These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.Examples of igneous rocks include obsidian and basalt.

Key words: Rocks, lithification, cementation and compaction, sedimentary rocks, examples of sedimentary rocks, other types of rocks.

Could the mitochondrial DNA of either James Carnegie or Countess Xenia be used to try to identify the skeleton of Tsar Nicholas?

Answers

The answer is neither. Mitochondrial DNA is passed down the maternal line from mother to daughter. The Tsar Nicholas is a male, so mitochondrial DNA could not be used to identify his remains through kinship analysis. Traditional DNA markers or Y-chromosome markers would be more appropriate. 

Final answer:

The mitochondrial DNA of James Carnegie or Countess Xenia cannot be used to identify the skeleton of Tsar Nicholas.

Explanation:

The mitochondrial DNA of either James Carnegie or Countess Xenia could not be used to try to identify the skeleton of Tsar Nicholas because mitochondrial DNA is inherited maternally and Tsar Nicholas would not have inherited his mitochondria from either James Carnegie or Countess Xenia. Mitochondrial DNA can only provide information about maternal lineage. Therefore, it would be more useful to examine the mitochondrial DNA of Tsar Nicholas, any known maternal relatives, or other individuals directly related to Tsar Nicholas through a maternal line.

3.)PORTION SIZE; is the amount of a food consume in single occasion.

7. Describe what happened as the ice melted. Where do you think the energy goes when it is not raising the temperature?

Answers

Final answer:

Ice melting at room temperature involves energy transfer from the environment to the ice, which breaks intermolecular hydrogen bonds and increases the entropy of the system without raising the temperature.

Explanation:

Phase Change in Ice Melting

When ice melts, the energy absorbed from the surroundings is used to break the hydrogen bonds holding the water molecules in a solid structure. During this phase change, the temperature of the ice does not increase; instead, the energy is dedicated to changing the state from solid to liquid. The water molecules in melting ice increase their kinetic energy until they can move freely, leading to a liquid state with higher entropy. This entropy increase signifies a greater degree of disorder within the system because the molecules have more freedom of motion in the liquid state than in the solid crystalline state.

Heat transfer during melting originates from the warmer surrounding environment, like room temperature air or your hand if you're holding the ice. As the energy is transferred to the ice, it becomes the kinetic energy of the water molecules, but since the process involves breaking intermolecular bonds rather than increasing speed of movement, there's no increase in temperature until all ice has melted

A plant that has been raised in a sterile environment shows symptoms of a viral infection. how would you explain this?

Answers

The answer would be: The viral infection was acquired by vertical transmission.

Vertical transmission happens when the plant parents are infected before the plants detach from it. It could happens during asexual reproduction or in seeds of sexual reproduction.
That means, the infection spread before the plant raised in the sterile environment. 
This can be explained by the concept of vertical transmission of a virus, i.e., the virus is inherited from a parent. During asexuak reproduction, the offspring is genetically identicle to the parent. Here, during the development of the offspring through the stem, root or bulb of the parent, the parent's virus is passed to the offspring. In sexual reproduction, viral transmission occurs as a result of seed infection.

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

Explanation:

The three ways prokaryotic cells are different from eukaryotic cells

Prokaryotic cells do not have cell organelles.The prokaryotic cell may contain flagella for locomotion.Prokaryotic cells are only present in unicellular organisms.

What are prokaryotic cells?

Prokaryotic cells are the primitive type of cells, that are present only in a unicellular organism. They do not undergo cell division full stop these cells do not have true cell organelles and a nucleus that DNA is present in coil form in the cytoplasm.

They contain ribosomes the organisms are bacteria that contain prokaryotic cells.

Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus that contains DNA or genetic material, it does not have a flagellum.

Thus, the differences are:

Cell organelles are not present in prokaryotic cells.

Flagella for prokaryotic cell movement may be present.

Only unicellular organisms contain prokaryotic cells.

Starch is broken down into individual units of maltose in the presence of an enzyme known as amylase. Which statement best describes the role of amylase in this reaction?

Answers

Final answer:

The enzyme Amylase plays a fundamental role in carbohydrate digestion. It initiates the breakdown of starch to maltose starting in the mouth and concluding in the small intestine where it acts as a catalyst, speeding up the reaction without getting consumed.

Explanation:

The role of amylase in the breakdown of starch to maltose is initiation. Amylase is an enzyme that initiates the chemical digestion process of dietary carbohydrates, specifically starches. It is a key digestive enzyme that is primarily produced in the salivary glands and the pancreas. The process starts in the mouth, where the salivary amylase begins the process of breaking down starch into smaller carbohydrate units, including maltose. This breakdown continues in the small intestine, where pancreatic amylase takes over and completes the digestion of starch to maltose.

In this reaction, the amylase functions as a catalyst, which means it speeds up the reaction without getting consumed in the process. It does so by lowering the activation energy required for the reaction, enabling the starch to be broken down into maltose at body temperature.

"abnormal enlargement of air sacs in the lungs can lead to which condition"

Answers

The correct answer is emphysema.
Emphysema is the enlargement of air sacs in the lungs.
It is a long-term, progressive disease of the lungs that primarily causes shortness of breath. People who have emphysema, their air sacs in the lungs (alveoli) is damaged. Over a period of time, the inner walls of the air sacs weaken and rupture creating larger spaces instead of many small ones. Normally, the lung tissue holds these small airways called bronchioles, open, allowing air to leave the lungs on exhalation. However, when the lung tissue is damaged like in the case of emphysema, these airway collapse, making it difficult for the lungs to empty and the air (gases) becomes trapped in the alveoli thus causing impaired gas exchange.
