Which two characteristics are used to classify stars on the Hertzsprung-Russell diagram?
size and density
density and composition
composition and temperature
temperature and absolute brightness
Answer:
Temperature and absolute brightness
Explanation:
The X-Axis of the diagram is heat, and it actually goes down in heat.
The Y-Axis is for brightness, and it works like a regular axis, meaning as it goes up, the number or unit of some sort, in this case luminosity, goes up.
Two characteristics are used to classify stars on the Hertzsprung-Russell diagram are temperature and absolute brightness
What is the Hertzsprung-Russell diagram?The Hertzsprung-Russel diagram or HR diagram is a graphical tool using a scatter plot used by astronomers to classify stars according to their:
luminositycolor temperaturespectral typeHere, The HR diagram plots as either
the temperature of the stars versus the luminosity OR the color of stars versus absolute magnitude.Therefore two characteristics used to classify stars on the Hertzsprung-Russell diagram are temperature and absolute brightness(Luminosity)

Select one:
a. carbohydrates
b. nucleic acids
c. lipids
d. proteins
Answer:
D is the correct answer.
Explanation:
proteins are the carbon compounds or biomolecule that helps in formation of muscles and bone and controls cell processes. Thus option D is correct.
What are Biomolecules?Biomolecules are involved in the maintenance and metabolic processes of living organisms.
Carbohydrates are polyhydroxy aldehydes or ketones.
They are classified as monosaccharides, oligosaccharides and polysaccharides based on number of constituting sugar units obtained upon hydrolysis.
Proteins are polymers of amino acids arranged in the form of polypeptide chains, it can be classified into primary, secondary, tertiary and quaternary structure.
For example, Myosin is the protein which involve in contraction of muscles.
Nucleic acids are the genetic material found in the cell. These are up two types such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Its function is to help in transfer of genetic information and synthesis of proteins by transcription and translation.
Lipids are water insoluble organic molecule, include fats, waxes, sterols, fat-soluble vitamins, phospholipids, etc.
Thus option D is correct.

According to the concept of entropy, what will likely happen to most molecules over time? A.They will bind to other molecules. B.They will break down. C.They will remain unchanged. D.They will turn into carbon molecules.
Answer:
B.They will break down.
Explanation:
Entropy is defined as the thermal energy per unit temperature that contribute to doing useful work in a system. The concept of entropy says that entropy is measured by the random or disordered motion of molecules of a system.
As the entropy will increase over time, the molecules will break down into two or more due to the random and disordered motion of molecules.
Hence, the correct answer is "B.They will break down.".
When we think about science and drawing conclusions we usually think of evidence. Factual statements or conclusions in science are based on observations that are :
~objective

How could the tomato plant’s response to being eaten by a hornworm caterpillar be described as a function of homeostasis?
Answer:
The required answer is given below:
Explanation:
This can be clarified with the idea of induced resistance. it is the capacity of a plant to react to the specific compound delivered from the damaged body parts, The dispersion of the synthetic animates all different plants parts and different plants to be less delectable and thusly not wonderful to eat. In this manner the more the degree of harm to the plant, the higher the volume of synthetic compounds delivered, and consequently the less delicious the plants and lower the harms negative criticism instruments. Since this reestablished the plants to moderately consistent inner environments, this is homeostasis.
Hornworm caterpillar harms tomatoes plants leaves, leaving holes. When a tomato plant is eaten, it discharges a compound substance called methyl jasmonate. The last would be gotten by adjoining plant parts or other tomato plants. The open tomato plants hence turn out to be less scrumptious. Subsequently, the caterpillar in the wake of crushing the underlying aspect of the tomato plants would not have the option to proceed with the taking care of and in this manner feed on each other prompting their death, turning them to cannabis caterpillars.
Since trying to keep up the generally consistent interior condition plant discharges methyl jasmonate to forestall further harm and in this manner guarantees the soundness of the plant.
An invasive species is a species that causes harm to other species by taking over a new ecosystem. Populations of invasive species tend to increase much faster than populations of other species. One reason that invasive species might be so successful is that they ?
Answer:
reproduce faster
Explanation:
you need to keep in mind, invasive species are completely new to their environment so the native species don't know how to react to this new species so the competition for their normal resources will be much harder to get than it usually would because they don't know anything ab the invader

Answer:
Below .
I hope the information give below is helpful .
Explanation:
In question 1 ;
The independent variable is the fertilizer
The dependent variable should be the rate of growth of the plants
The constant doesn't change so other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.
The controlled variables might be things such as the the quality of soil and the amount of water given to the plants. If these factors were not constant, and certain plants received more water or better soil than others
The experiment in question 1 is a controlled experiment
The part of the garden that didn't receive fertilizer is the control group
According to the question; She didn't hypothesize .
In question 2 '
The independent variable is the floor wax
The dependent variable was protecting the floor tiles against scratches.
It is a controlled experiment but there's no much information to determine if there is any variability and repetition )
The sections that received no wax is the control group
There is no hypothization (if that's a word :) ).The shopping mall didn't hypothesize (maybe that the tough steel would be better )
I'm not sure of any constant needed when applying floor wax.

Create an atom with mass number equal to
3 and neutral charge. Click the red button
when done.
In order to solve the question, one must understand that:
An atom is made up of neutrons which has no charge, negatively charged electrons, and positively charged protons. The mass number of an atom is the number of protons plus neutrons of the atom. It is also the atomic mass number of the atom.A neutral atom has an equal number of positive (proton) and negative (electron) charges.Hence, in order to create a neutral atom with a mass number of 3, the proton and neutron number must add up to 3 while the proton and electron number must be equal.

What assumptions does the author make when presenting the information? Is there other historical data that should be considered before making such claims? *EASTER ISLAND*
The correct answer to this open question is the following.
The assumptions that the author makes when presenting the information are that the author makes a comparison of what could have happened on Easter Island to other places in the world that suffered a similar fate.
There is practically no other historical data that should be considered before making such claims. Indeed, what happened on Eastern Island, also called RAPA NUI by the natives, is a mystery. Yes, there are legends and oral tradition stories that refer to what could have happened, but nothing based on scientific terms that could be demonstrated. Theories varied form the possible scenario of the sinking of the Lemurian continent. Due to that incident, many natives decided to leave and sail to other regions of the planet such as Hawaii, the Polynesian islands, and of course, Easter Island.
