Some jellyfish are transparent, how will this affect their ability to survive?
So predators cannot see it as well
Explanation:
It will affect their ability to survive because...since Jellyfish bodies are transparent, that means they are less visible to predators or threats. Which will affect their way to survive because since they are less visible to predators, it gives them a better chance for survival since their predators can't see them very well. It also gives them a better chance for survival because hunters won't be able to see them well enough to catch them because they blend in with the water, which is called transparent.

Which statement explains what happens as magma rises inside a volcano?
Gases will contract in the chamber.
The pressure of the gas will disappear.
The magmatic pressure decreases.
Magma moves to other chambers.
Answer: the answer is C which is “the magmatic pressure decreases“
The magma rises and collects in chambers within the crust and as magma fills the chamber, pressure grows. If the pressure gets high enough the magma can break through the crust and spew out in a volcanic eruption., but If the pressure is low, do not break the crust. Thus the correct option is C.
What is molten magma?Magma is a molten and semi-molten rock mixture present under the surface of the Earth.
This mixture is usually made up of four parts such as a hot liquid base, called the melt, minerals crystallized by the melt, solid rocks incorporated into the melt from the surrounding confines, and dissolved gases.

What are limiting factors?
A limiting factor is a variable of a system which causes a noticeable change in the output or another measure of a type of system. These are present in a limited amount.
Limiting factors are of two types: Density-dependent factors and density-independent factors. Density-dependent factors have varying impacts according to the size of the population. Density-dependent factors include food availability, predator density and disease risk. Density-independent factors are not influenced by a species population size. Density-independent factors include temperature, altitude, amount of sunlight, etc.

In Plants photosynthesis can only take place in the presence of sunlight during the day, respiration happens all day long, hence option c is correct.
What is respiration in plants?Plants' respiration is visible at night and day, plants consume oxygen during respiration while also releasing carbon dioxide. Both photosynthesis and respiration take place during the day.
However, only respiration takes place at night, which uses oxygen. A sequence of chemical processes known as cellular respiration converts glucose into ATP, which may then be utilized as energy for a variety of bodily functions.
Glycolysis, citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.
Therefore photosynthesis takes place during the day but plants respire all the time, hence option c is correct.
