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.

Answer:

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.

Compare parasympathetic nervous system vs sympathetic

Galina-37 [17]

Answer:

Parasympathetic nervous system effects are slow or inhibit function, where is sympathetic, is responsible for the intense physical activity.

Explanation:

The autonomic nervous system or ANS is divided into 2 distinct systems on the basis of their effects- the parasympathetic nervous system and the sympathetic nervous system.

Both of these have opposite actions on the functions that they maintain.

The sympathetic nervous system regulates the body for a high level of physical activity and also known as fight or flight. It fasts the functions of the body according to the situation.

The parasympathetic nervous system is having the opposite effect of the sympathetic nervous system slows high energy functions and relaxes the body.

Thus, the comparison of these nervous systems is mention above.

EastWind [94]

Answer:

During fertilization, chromosomes from haploid gametes combine, and a diploid zygote is formed.

Explanation:

Fertilization is the union of the male gamete(haploid chromosomes) with the female gamete(haploid chromosome) to form a diploid cell called zygote (with diploid chromosomes).

Water can act as either a(n) _____ or a _____. acid, base solute, solvent anion, cation salt, mixture

IgorC [24]

Water can act as either a base or an acid. Water acts as an acid by donating a hydrogen ion when it reacts with a stronger base such as sodium hydroxide. Water may also act as a base when it accepts hydrogen ion when reacting with a strong acid such as hydrochloric acid. This is based on Bronsted concept and definition of a base ( proton acceptor) and acid (proton donor). Such a compound that can act as a base and as an acid is called an amphiprotic molecule.
