Patrick pours 1 cup of lemon juice in a glass. He pours 1 cup of milk in a second glass. The two quids are both left on the same bench for an hour. Patrick then compares the two liquids.which of the following would be different for both liquids ?
The state or phase of the two liquids could be different. Color, volume, and temperature are not necessarily different for both liquids. So, the correct option is B.
What is Liquid?A liquid is one of the three classical states of matter in physics and chemistry – the others being solid and gas. A liquid has a specific volume that never changes yet flows freely and conforms to the shape of its container.
Although the particles in a liquid are relatively close to each other and able to pass each other, intermolecular forces maintain their cohesion. Juice, water, milk and other common liquids contain oils and fats. Although they differ from solids in that they do not have a definite shape, liquids differ from gases in that they have a definite volume.
So, the correct option is B.

Which protist group is thought to be most closely related to animals?.
Answer:
Choanoflagellates are the closest relatives of animals. They are also single-celled protists and have a flagella at one end of their cell.
Explanation:
The closest living relative of the animal is the protist choanoflagellates, that reproduce sexually and asexually.
Choanoflagellates are marine and freshwater protozoa that are widely distributed around the world. They have a distinctive flagellum with a whip-like shape and a collar made up of shorter hairs, similar to the ‘collar’ cells that filter out food in sponges.
By feeding on bacteria and debris, they feed on their larger predators and bring dissolved organic matter back into the water column. In terms of both number and feeding rate, Choanoflagellates play a vital role in the microbial food web that sustains the global ecosystem.

If a deer eats grass, what percentage of energy will the deer acquire from the grass? 0. 1 percent 1 percent 10 percent 100 percent.
The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.
In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another. The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.What is the position of deer in the food chain?The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.
Thus it is clear that 10 percent of energy will the deer acquire from the grass.

1. Find the graph paper in your kit and graph your results by putting the generation number along the x-axis and the number of bears along the y-axis. When drawing the lines, use a different color to represent each type of bear. (Make sure to indicate which color goes with which type of bear.)
2. Summarize the trends you see in each population from each generation.
a. Dark bears-
b. Light bears-
3. Explain how this experiment demonstrated natural selection.
Based on the nature of their environment, natural selection will favor the bear type that is better suited to its environment.
What is natural selection?Natural selection is a process of evolution in which organisms which are better suited to their environment are selected for survival.
In the bear population, natural selection will favor each bear type that is better suited to its environment.
In cold and icy environments, the light bears are better suited to their environment and are naturally selected for survival.
In temperate and warm climates, dark bears are better suited to their environment and are naturally selected for survival.
Therefore, natural selection will favor the bear type that is better suited to its environment.

color goes with which type of bear.)
Okay, this is REALLY simple. Just make a graph with the info given to you.
2. Summarize the trends you see in each population from each generation.
a. Dark bears— Dark Bears with their arms up always had double to amount of the Dark bears with their arms down, and past Generation 3 the Dark Bears had more numbers than the Light Bears
b. Light bears— Light Bears start off with only arms down, and when arms up bears are introduced, they are more common/prevalent for the majority of the generations, having usually twice as much as the bears with the arms down.
3. Explain how this experiment demonstrated natural selection.
This experiment shows natural selection by hosting events in which certain bears are put more at a risk than other bears, such as environment changes favoring dark bears, or bears with their arms up.
4. If the environmental situation changes, is it possible for a population to be restored?
Via adaptations, it is completely possible for a bears population to thrive again, but perhaps not with the same characteristics.
5. How can natural selection help explain how a population becomes extinct?
As the environment changes, it may favor a species less and less, which leads to their decline, if they are unable to change with the times and adapt, the species will go extinct as it is no longer fit in its environment.
6. Which generations saw a population altering incident? Use your imagination to invent a possible environmental incident that could have caused this shift in populations.
The Light Bears faced a decline, and most bears with their Arms Down faced a decline too. Light bears could be explained via environmental factors, such as their original habitat being snowy, and without the snow they're more visible given their lighter colors. Arms down could simply be a dominants v recessive trait
7. How can environment impact a particular population of a species?
If a certain species is not fit for the changes made in an environment, it could result in either their extinction, or a mutations/adaptations so that the species can continue to thrive.
8. What are some natural reasons that animals in a population might die?
Competition, not enough resources, environmental changes.
9. What are some man-made reasons that animals in a population might die?
Things such as deforestation, overhunting, and introducing invasive nonnative species.
10. What are some ways that man has helped animals maintain their populations?
Protecting endangered species, rehabilitating injured animals, making animal reservations, etc.

Answer:
hemoglobin, hemoglobin carries oxygen in the blood and it is made up of four subunits, two each of the α and β types.
Explanation:
Protein can have varying structures namely primary, secondary, tertiary and quaternary. An example of protein with a quaternary structure is hemoglobin.
What are different structures of protein?The function of protein is completely dependent on its folding. Protein can be folded into many types.
The macromolecule protein can have the following structural classification:
Primary structure: It is a linear chain of amino acids.Secondary structure: The linear chain folds to form secondary structure.Tertiary structure: it involves further folding of protein chain.Quaternaty structure: it is the spatial arrangement of the folded protein.Hemoglobin is one of the proteins that exhibits quaternary structure.
Thus, hemoglobin is an example of a protein that has quaternary structure.
