Answer:
The correct answer is - O and 6.9; 7.1 and 14
Explanation:
A measuring scale that tells about the acidity or basicity or alkaline nature of a particular object or solution is possible with the help of a pH scale that measures how acidic or basic a solution or object is.
It ranges between 0 to 14. pH less than 7 or ranging from 0.0 to 6.9 is acidic and more than 7 or from 7.1 to 14.0 is basic or alkaline in nature. A measure of the relative amount of H+ ion and OH- ions in water is pH.

Is the mass–kinetic energy relationship directly proportional (as one variable increases, the other increases) or inversely proportional (as one variable increases, the other decreases)?
Answer:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity.
Explanation:
The mass-kinetic energy relationship is ; Directly proportional
The Kinetic energy of an object is directly proportional because an increase in the kinetic energy of a moving object leads to an increase in the mass of the object and also to the increase in the velocity of the object squared.
i.e. K.E ( kinetic energy ) = [tex]\frac{1}{2} mv^2[/tex]
Hence we can conclude that the mass-kinetic energy relationship is directly proportional.

If an air mass is sinking, it must be
A. cold and less dense
B. warm and more dense
C. cold and more dense
D. warm and less dense
Answer:
The awnser to your question is C.
Explanation:
The colder matter is the atoms get closer therefore making the matter more dense. A. is half correct but if the matter is cold it wouldn't be more dense because when something is less dense it goes above whatever is around it. Take for example water and oil. They seperate into different layers due to density. Hope this helps. :)
The airmass is a large homogenous mass of air over a region that could be for many days.
The volume of air is defined by the temperature and water vapor content. Airmass may spread from hundreds to miles and are classified according to latitude and altitude. There are 4 types of air mass artic, tropical equatorial, and polar. The airmass that is light is warm and has a low pressure always lifts upwards. The cold and cool airmass always settles as it's dense and heavy. Hence the option C is correct.Learn more about the air mass is sinking, it must be.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

Somatic cells divide by ___________________ to provide two identical daughter cells that look like the original cell while sex cells divide by _______________________ to provide four different daughter cells
Answer:
somatic cells divide by mitosis
sex cells divide by meiosis
Answer: Somatic cells divide by __mitosis__ to provide two identical daughter cells that look like the original cell while sex cells divide by __meiosis___ to provide four different daughter cells.
Explanation:
Somatic cells are non-sex cells, so mitosis is the answer for the first blank, since mitosis does not make sex cells. Meiosis does, so the answer to the second blank should be meiosis. Also, meiosis yields four daughter cells while mitosis yields only two, so the answers given should make sense.

write the name of reproduction process that occurs in tapeworm?
Answer:
Hermaphroditic ReproductionExplanation:
See image for more
Depending on the species and circumstances, tapeworms can reproduce sexually or asexually. Proglottids, the several body segments that make up a tapeworm, are composed of both male and female reproductive cells.
What Hermaphroditic reproduction occurs in tapeworm?Some parasitic species, like the tapeworm, are both hermaphroditic and self-fertile, ensuring reproduction even if the parasite is the only member of its species present in the host.
Because tapeworms are hermaphrodites, each segment has both male and female reproductive organs. As the segment is pulled away from the neck, viable eggs will be released into the environment. When the segment is loaded with eggs, it separates from the adult tapeworm and is excreted in faeces.
Therefore, Hermaphroditic reproduction process that occurs in tapeworm.

Answer:
It should be, More wood will be available for building homes
& Organisms will lose their habitat
_______________________________________________
*rate this answer and say thanks please!
I put this same answer on a different question.
Hi there! So among the options, there are:
Organisms will lose their habitat
Groundwater in the area will be reduced
More wood will be available for building homes
Runoff will be reduced once the streets are paved
Think about it. This is asking how the water cycle will be affected.
It wouldn't have anything to do with organisms, this is about water. It wouldn't be involving wood, since we're talking about water.
A and C are no longer options.
The answer is B, Groundwater in the area will be reduced. It took me a bit on this one, too, since it's a bit tricky. I also got it right on my exam and I do FLVS, this is in Earth Space Science.

All eubacteria and archaebacteria are prokaryotes. Living organisms that are made up of cells that have nucleus are called _
Answer:
Living organisms that are made up of cells that have nucleus are called EUKARYOTES
Explanation:
Living organisms are grouped into two according to the composition of their cell components. These include:
--> The PROKARYOTES: these organisms possess a very simple cell structure with no definite nucleus. Example of such organisms include the eubacteria (that is, 'true' bacteria), archaebacteria ( which is also a type of bacteria) and blue green algae.
--> The EUKARYOTES: these organisms possess a complex cell structure with a well defined nucleus. The nucleus is found enclosed within a nuclear membrane. Hereditary materials are located within the nucleus and the cell has other components known as the cell organelles. These organelles include the mitochondria, Golgi apparatus, Endoplasmic reticulum, Ribosome, lysosomes. Example of eukaryotes are the animals, plants, fungi, and protists.
Therefore, Living organisms that are made up of cells that have nucleus are called EUKARYOTES
