eukaryotes have organized nucleus and organelle bounded by membrane

Answer artificial levees

Explanation:

Answer:

The Prokaryotic Cell

Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid

Answer:

Oils do not dissolve in water

Explanation:

Waxes are one of the forms of lipids, which are waterproof.  

• Lipids are insoluble in water and are hydrophobic. They perform many essential activities within the cell.  

• One of the forms of lipids is waxes, which envelopes the leaf surfaces of some plants, and the feathers of some aquatic birds.  

• Due to the hydrophobic nature of waxes, they inhibit water from attaching to the surface. Thus, waxes are waterproof.  

• The waxes are the long-chain fatty acid chains attached covalently with the long-chain alcohols.  

Thus, waxes are the lipids that demonstrate the waterproof property of the lipids.

Answer:

Independent: Time on Social Media

Dependent: Less books read.

An independent variable in an experiment is a variable whose outcome is not affected by other variables present in the experiment.   while

A dependent variable is a variable whose outcome is directly determined/affected by changes made by an independent variable in the experiment.

The number of books read is a dependent variable because it depends on the amount of time spent on social media ( independent variable ).

Hence we can conclude that the Independent variable in the experiment is the time spent on social media while the number of books read is a dependent variable.

Even if we stopped burning fossil fuels, the Earth would continue warming up for another few decades because of all the heat we've already produced. Global temperatures would climb – finally stabilizing at a level much higher than we've ever known.

Answer:

the results of the investigation led to new scientific questions

Explanation:

The basis of every scientific question asked is an observation made. Scientific questions are questions that emanate from an observed problem and leads to the formation of a testable explanation (hypothesis). In this question, an investigation was made by a scientist and it was discovered that increased temperature decreases the number of offspring that an organism produces.

However, the scientist asks a new question about the impact of climate change on the species. This is because an observation has been made again, from the previously concluded investigation. Hence, after completing the investigation about the effect of temperature on the number of offsprings an organism can produce, an observation was made, ultimately leading to a new scientific question.

Answer:

c

Explanation:

Answer: A physical property is when something can be observed or measured without being changed. A chemical property is when a substance undergoes a specific chemical change. Examples of physical property are color or density. Examples of chemical properties are flammability or heat of combustion.

I hope that this helps you !

The difference between physical and chemical properties of a substance depend on the fact that they affect the substance physically or affects its properties and identity.

Substances have characteristics that help in identify and thus classify them. Two of the broad classifications of these would include the chemical and physical properties of a particular substance.

Thus, the physical and chemical properties of a substance depend on the fact that they affect the substance physically or affects its properties and identity.

Answer:

An experimental group

Explanation:

An experimental group is a test sample or the group that receives an experimental procedure. This group is exposed to changes in the independent variable being tested.

Answer:

Cellubrevin, like the synaptic vesicle proteins synaptobrevins I and II, can be cleaved by tetanus toxin, a metallo-endoprotease which blocks neurotransmitter release. However, nonneuronal cells are unaffected by the toxin due to lack of cell surface receptors for its heavy chain.

Explanation:

During the first stage of photosynthesis, called the light-dependent reaction, sunlight excites the electrons in the chlorophyll pigment. The organism uses this energy to create the energy carrier molecules ATP and NADPH, which are crucial for carbon fixing during the second stage.

The first two stages of photosynthesis depend directly on light because light energy is used to make ATP and NADPH. In the final stage of photosynthesis, ATP and NADPH are used to produce energy-storing sugar molecules from the carbon in carbon dioxide.

Answer:

It is an unconcious process

Explanation:

Homeostasis is when the body is made sure to have a constant environment inside so that the body can work at it's optimum conditions .... constant temperature, constant pH etc ... you do sweat when you feel hot but you can't control it... your mind just tells it to... vadodilation and vasoconstriction for a constant temperature occurs for a constant temperature as well(when vessels dilate and constrict), your mind allows the vessels to do so without you thinking about it.

Homeostasis is an unconscious process.

Hence, controlling homeostasis is an unconscious process.
