Wolf spiders carry their young on their backs. how does this in their survival?

it provides care to the young.

it in finding a mate.

it makes looking for food easier.

it makes the spiders less vulnerable to predators.

it intimidates other spiders.

It provides care to the young.

Wolf spiders are unique members of the spider species. They are unique in the sense they carry their young ones on the back after hatching of the eggs. The egg sac of these spiders remains attached at the spinnerets which are present in the end of the abdomen. After hatch the spiderlings climb up the back and remain their for several weeks until they develop large enough to disperse themselves.  

Therefore, It provides care to the young. is the correct option which reflects the fact that wolf spiders help their young ones for survival.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
