1. What is the name of the reagent used to test for the presence of proteins? (1 point)

           Biuret reagent  

2. What color indicates the presence of protein in a solution when the reagent is added? (1 point)  

When Biuret is added, it would turn blue when it is negative but if it is positive then it would turn to a purplish to a dark purple. Showing that there is protein.

3. Which substances tested were positive for protein? (2 points)

The ones that were tested positive were milk solution and 50% egg solution.

4. Describe in your own words what we should do if the test tube for di-water tested positive for protein. (2 points)

Since Di water is our negative control, we know that there would be no proteins but if it was tested positive. Then we should start the experiment all over again this time with new, clean equipment.

The name of a double layer of phospholipids is called a lipid bilayer.

The lipid bilayer is a fundamental component of cell membranes and plays a crucial role in maintaining the integrity and function of the cell. It consists of two layers of phospholipids arranged in such a way that the hydrophobic (water-repellent) fatty acid tails are sandwiched between the hydrophilic (water-loving) phosphate heads.

This arrangement creates a barrier that controls the passage of substances into and out of the cell, allowing for selective permeability. The lipid bilayer also houses various proteins, cholesterol molecules, and other components that contribute to the overall structure and function of the cell membrane.

Thus, the correct option is lipid bilayer.

The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.

Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.

The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.

The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.

Thus, the property of water that is shown in the given statement is cohesion.

Identify which property of water cohesion, adhesion, or heat capacity applies to each observation below.

1. Large, circular lily pads are able to float on the water's surface.

Answer:

Distance is 500 m and displacement is 0.

Explanation:

Distance traveled by an object is equal to the total path covered during the entire journey. Displacement of an object is the shortest path covered.

In this case, we need to find the distance and the displacement of the race car drivers in the  Indy 500 m race in a circular path.

In a race, the object must reach the initial position after some time. It means that the final and the initial position is the same. As a result, the shortest path covered i.e. displacement of the car is equal to 0. On the other hand, total traveled distance is 500 m.

The diagram is a representation of the diffusion.

Explanation:

In this image, there are molecules or concentrations of a particular substance is represented by the purple circle on both sides of the box in left side concentration is higher than the right side.

So the movement of these molecules is from the left corner to the right down the concentration gradient, this type of movement of the substance is known as the diffusion which moves from high concentration to low concentration.

Diffusion is the movement of molecules from the higher concentration to lower concentration.

Diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration. In the image, higher concentration of molecules are present on the left side whereas lower number of molecules are present on the right side of the image.

So here diffusion occurs by movement of molecules from higher concentration to lower concentration means from left to right side of the image until the concentration becomes equal so we can conclude diffusion is the movement of molecules from the higher concentration to lower concentration.

Soil research has shown that soil profiles are influenced by five separate, yet interacting, factors: parent material, climate, topography, organisms, and time. Soil scientists call these the factors of soil formation

Answer:

Factors that determine a soil's characteristics include: the type of parent rock from which the soil forms, the climate in the area, the slope of the land, the type and amount of vegetation, and the length of time the rock has been weathering.

Explanation:

Answer:

polyp

Coral polyps secrete a rock-like skeleton of calcium carbonate around them. Calcium carbonate is also the dominant consituent of the rock, limestone. Because modern corals live in large colonies, these skeletons can become quite large, sometimes forming reefs.the soft tissue decays which leaves a hard skeleton behind the skeleton also that was preserved as a fossil of ancient coral and the coral that exists today all belong to the order of  Scleractinia (SCLER-ac-TIN-ee-a). in the past the fossils found today lead to the conclusion that their where other kinds of coral which are now extinct The order Rugosa was dominated by solitary corals in which each coral polyp had its own skeleton. Rugose means wrinkled or rough, and the outer surfaces of most rugose coral skeletons has a wrinkled appearance. Because some of the solitary rugose corals formed horn-shaped skeletons, they are called horn corals. Some Rugose corals also formed colonies and coral heads. The order Tabulata consisted entirely of groups of coral animals that lived in large colonies with a shared skeleton. These colonial corals grew in mounds, branching shapes, as chain-like shapes, and even in shapes resembling pipe organs.

Answer:

Reproduction is the process of producing offspring, whereas heredity is the process

of passing on traits.

Explanation:

PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!

Reproduction generally means making copy of something, like giving birth/breeding, duplicating.

Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!

They definitely aren’t same!

Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.

Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.

Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.
