Answer:
Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it. Avoid touching your eyes, nose or mouth. Germs spread this way.
Explanation:
Answer:
H1N1 influenza can be avoided by getting vaccinated, washing your hands, avoiding contact with sick people, and staying home if you are sick.
Explanation:
A micromolecule is a molecule that is relatively smaller than a macro-molecule.
A micromolecule is the smaller molecule that can be chained together with other micromolecules to make a larger molecule.
Explanation:
Asexual reproduction occurs by cell division during mitosis to produce two or more genetically identical offspring. Sexual reproduction occurs by the release of haploid gametes (e.g., sperm and egg cells) that fuse to produce a zygote with genetic characteristics contributed by both of the parent organisms.
if it helped then plz mark me as brainliest
B.body cells
C.zygote cells
D.epithelial cells
Answer: Sex cells
Explanation:
They are not valid because the student did not control all the variables that can affect plant growth
They are valid because the dependent variable caused a change in the independent variable.
They are not valid because the time frame to grow a plant is too short.
They are valid because the dependent variable caused a change in the independent variable.
Answer: Option C
Explanation:
The validity of a student’s result is basically based on how the dependent variable caused a change in the independent variable. A dependent variable is one which a scientist produce a variable and finds means to explain it in a proper way. An independent variable is one that is formed to compliment the dependent variable.
When the independent variable increases it causes decrease or increase in dependent variable. A intermediate or intervening variable is found which helps explain about the changes happening between the Independent and interdependent variable.
Answer:
Option (c) ''They are valid because the dependent variable caused a change in the independent variable'' is the correct answer.
Explanation:
The dependent variable is the one which is the center of observation. It is changed during the reaction and affected by it. When we measure the value of the reaction we always measure the dependent variable.
The independent variable is the one that is changed to cause the change in the value of the dependent variable. We can say that the dependent variable depends on independent for its reaction.
So dependent and independent variables are correlated with each other which tells the authenticity of the experiment.
B. The lithosphere is denser than the asthenosphere.
C. The asthenosphere is denser than the lithosphere.
D. The lithosphere has the same density as the core.
Answer:
A
Explanation:
Isostatic equilibrium is used to state why some regions of the lithosphere have greater elevation than others. The crust ‘floats’on the‘liquid’ mantle below and different regions of the crust submerge into the mantle differentially depending on their local densities or weight. Heavier regions such as in mountainous region (like the Himalayas) are sunken deeper into the mantle that other regions. Every local region has its own local isostatic equilibrium.
Answer:
The correct option is Option C
i.e. Asthenosphere is denser than lithosphere.
Explanation:
Asthenosphere is the layer situated below the lithosphere.
Theory of isostasy says that the layers above the other layer must have lesser density. This has two explanations. Firstly, if its not hold, then the denser above layer would sink below the less denser bottom layer. Secondly, as we go inwards, the pressure increases. This leads to the lower layers have greater density. So, as Asthenosphere is situated below the lithosphere, it has higher density.
