Harvey mixes two liquids. Which observation of the new mixture most likely indicates a precipitate is forming? a cloudy appearance a bubble formation a change in color a change in odor
The appearance of a precipitate in an aqueous phase reaction is easily signaled by a cloudy appearance of the reaction mixture.
A precipitate is formed when reaction between two aqueous reactants yields an insoluble product. That insoluble product is referred to as a precipitate. Usually precipitates are formed during double decomposition reactions.
When a precipitate is formed, we can easily observe it from a cloudy appearance of the reaction mixture.

What is happening within the moon jelly population when the size of the moon jelly population is stable.
Answer:
The jelly is able to hold the weight of gravity
Explanation:
To reproduce, organisms need to release energy from energy storage molecules. If there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births. Fewer deaths would also cause the jelly population to increase.
What are moon jellies made of?The moon jelly is one of the most common jellyfish in Rhode Island. Its body shape resembles an umbrella, with four equal-sized horseshoe-shaped gonads in the center of its body.

When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in complexity?
Answer:
Tissue
Explanation:
Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.
Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".
The order is as follows:
Cell-----> Tissue-----> Organ-----> Organ systems

Continents are found in the continental crust. True or false?
Answer:
true (more info below)
Explanation:
The continental crust is a sheet of granite, sedimentary and metamorphic rocks that surround the continents and the shallow seabeds near their coasts, known as the continental shelves. This is less thick than the substance of the mantle of the Planet, which therefore "floats" on top of it.

The expansion of the ranges of tropical fish was most likely caused by-
A. agricultural runoff that contributes to dead zones in the ocean
B.global droughts that raise the salt concentration of ocean waters
C.the rising temperatures of ocean waters
D.acid rain pollution that lowers the pH of ocean water
Answer:
C
Explanation:
The expansion of the ranges of these fish was most likely caused by the rising temperatures of ocean waters. This is because these types of fishes live in both fresh-water and salt-water but only in aquatic tropical environments around the world. The increase in temperatures of ocean waters has provided more suitable habitats for these fishes to expand to.

a flower
a bacterium
a fish
Answer: A. ,C.
Explanation: It's in the food chain and constantly need's water.
The correct answers are:
A treeA flowerA bacteriumA fishWhy organisms need sunlight?All of these organisms can have all of the energy they use to move, grow, and survive traced back to radiant energy from the Sun. Trees and flowers undergo photosynthesis to convert sunlight into energy in the form of glucose, which they use to grow and carry out metabolic processes.
Bacteria can also undergo photosynthesis, or they can use organic matter as a source of energy, which ultimately comes from the Sun through the food chain. Fish, as well as other animals, obtain their energy by consuming other organisms that have obtained energy from the Sun through photosynthesis or other means.
Humans are also ultimately dependent on the Sun's energy, but they obtain their energy indirectly through the food they consume, rather than directly from photosynthesis.

Why doesn’t urine flow back to the ureters?
Answer:
With vesicoureteral reflux, urine flows backward from the bladder, up the ureter to the kidney. It may happen in one or both ureters. When the "flap valve" doesn't work and lets urine flow backward, bacteria from the bladder can enter the kidney. This may cause a kidney infection that can cause kidney damage.
