Answer:

The correct answer is option A. Kelvin.

Explanation:

Kelvin is the is unit of temperature measuring like Celsius and Fahrenheit. The planet's temperature is mostly measured in the kelvin unit of temperature however degree Celsius and degree Fahrenheit also use to measuring in many cases.  

Kelvin is an international unit of temperature which is equal to the -273 degree celsius and in planetary science mostly kelvin is used as the unit of measurement.

Thus, the correct answer is option - a. kelvin

A mutation in the RAS gene can cause cells to divide uncontrollably, which is a key feature of cancer. However, not all RAS gene mutations lead to cancer as other factors also play a role. A sketch could demonstrate a normal cell with a functioning RAS protein and a mutant cell with an overactive RAS protein causing uncontrolled cell division.

In a normal cell, a gene called RAS helps regulate cell division. Mutations in the RAS gene could lead to constant activation of this gene, causing cells to divide uncontrollably, which is a key feature of cancer. A sketch illustrating this may have a cell with a well-labelled RAS protein in a normal cell comparing this to a 'mutant' cell with an overactive RAS protein causing increased cell division.

It's important to note that not all mutations in the RAS gene lead to cancer. Other factors, such as cell environment and affected tissue type, also play a critical role in whether a RAS mutation will indeed lead to the development of cancer.

The nurse should prepare this kind of patient for tocolytic therapy, corticosteroids as well as hospitalization.

Explanation

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.

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.

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.

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

The correct answer is C

i had this question and it was price

hope this helps

Answer:

Price

Explanation:

Out of all the options "Sizes" is the only option that is not included on the label.

The nutrition facts label is nutritional information that is written on the packaged food that shows the percentage of the nutrients present in the packaged food.

Different countries in the world has their nutrition guidelines for all packaged food that are been sold in daily basis

nutrition information that's well detailed helps the consumers to have a good eating habit and this information can only be produced by the producers.

Some information on the label includes;

1.)INGREDIENTS; the ingredients are usually arranged in certain order I.e from the major ingredients(highest quantity) to minor ingredients (lowest quantity) such as sucrose,additives and others. and any FDA- certified must be included.

2.)DAILY VALUE; It is used on food label to so that the consumers can plan a healthy diet, it provide the percentage of the nutrients that is contained in a serving of food.

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

Answer:

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 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.
