Mercury is a metal which is liquid at room temperature. It has shown to have unique properties like the presence of ice. This is because the planet does not get sufficient heat transport.
How ice is present on Mercury?Mercury does not have a substantial atmosphere to transport heat around the planet. The darkness of the planet allows ice to remain frozen despite the extreme temperature of the world.
The Earth-based radar imaging of Mercury has revealed areas of high radar reflectivity near the poles that could indicate the presence of ice in these regions. There are dozens of areas with generally circular shapes.
Mercury is the only metal that is a liquid at standard temperature and pressure, all the other metals are solid. The other metals like rubidium, cesium, and gallium melt at a temperature just above room temperature but mercury stay as a liquid at all the temperatures.

If the percent solute concentration is greater in the fluid outside a cell than inside a cell, how will the water flow
Answer:

Pauline took two small identical containers and filled them with the same amount of water.She dissolved a tablespoon of salt in one of them and placed both containers in a freezer.Pauline then observed them every five minutes until one of them had frozen.What is most likely the dependent variable (outcome variable) in this experiment?
A.The time it took for the liquids to freeze
B.The amount of water in each container
C.The amount of salt in each container
D.The type of liquid
Answer:
A
Explanation:
This line should explain it "Pauline then observed them every five minutes until one of them had frozen."
The most likely dependent variable (outcome variable) in this experiment is the time it took for the liquids to freeze. The correct option is A.
What are the variables of the experiment?The variables of an experiment are the factors of the object on whom the experiment is done or the factors which affect the experiment. There are three types of variables. These are dependent, independent, and control variables.
Independent variables are those which can not be controlled by the person who is doing the experiment. The dependent variables can be changed or controlled by the experimenter.
A controlled scientific experiment will be controlled by the scientist, and it is to be checked that what time and what face of the experiment is going on.
Therefore, the correct option is A. The time it took for the liquids to freeze.

How do the different diets of organisms affect their eating patterns?
Answer:The evolutionary history of hominins has been characterized by significant dietary changes, which include the introduction of meat eating, cooking, and the changes associated with plant and animal domestication. Decades of anthropological research have been devoted to elucidating this dietary history, in part because these shifts were likely associated with major anatomical and cultural changes (e.g., the increase in relative brain size and the advent of modern civilization via agriculture). However, this reconstruction is also crucial for understanding the evolutionary context of our modern diets and the diseases often associated with them.
In parallel with the historical reconstruction of hominin diets, molecular evolutionary analyses have been used to interrogate the genome for signals of genetic adaptations to different dietary regimes. A major advantage of many evolutionary genetic approaches is that they do not necessarily require strong assumptions about the specific genes and alleles that were targets of diet-related selective pressures. For this reason, evolutionary genetic analyses have the potential not only to inform existing adaptive hypotheses of hominin dietary history, but also to help generate new ones.
Here, we bring together these two areas of inquiry, namely anthropology and evolutionary genetics, to highlight their recent findings related to human dietary history and to discuss the limitations of different approaches. We start by providing a brief overview of the major dietary shifts in hominin evolution and discussing the evolutionary genetics methods and approaches used to identify signals of natural selection. We then review the results of genetic studies aimed at detecting the loci that played a major role in dietary adaptations and conclude by outlining the potential of future studies in this area.

Meaning of invertebrate and vertebrate
Answer:
Vertebrate:spine Invertebrate:no spine
Explanation:
Answer:
Invertebrates are animals that do not have backbones. 95%-97% of the members of the animal kingdom are invertebrates such as sponges, jellyfishes, squids, and roundworms.
Vertebrates, on the other hand, are animals with a backbone or a vertebral column and are composed of six groups: mammals, birds, reptiles, amphibians, and fishes. Humans are members of the vertebrates family too but are sometimes exempted from the list when the discussion leans towards animals.

what is the role of a receptor in helping an organism maintain homeostasis
The role of a receptor in helping an organism maintain homeostasis is to detect stimuli and sends information to the control center. Thus, option C is correct.
What is homeostasis ?
Any self-regulating mechanism by which biological systems have a tendency to retain stability while responding to environmental factors that are best for survival.
The body's homeostasis keeps all cell processes and enzyme activity at their ideal levels. Despite changes in internal and external conditions, it is the maintenance of a constant internal environment.
As an instance of homeostasis in a biological system, the regulation of body temperature in humans is a good example.
Therefore, the control center receives input from the sensory receptor or sensor. Option C is correct.

Why is DNA replication significant for maintaining genetic stability
What process of DNA is represented in the diagram below?
Answer:
DNA Replication
Explanation:
Because DNA's two strands are complementary, it can reproduce itself. This means that one strand can serve as a template for the creation of the other. It occurs just prior to cell division via mitosis or meiosis, allowing each new daughter cell to have a full genome.
The two strands of DNA must first separate from one another before replication can begin. DNA helicase is an enzyme that breaks the hydrogen bonds that hold the two strands together, allowing them to separate.

If an organism has more specialized cells, its cells ________
A. can survive on their own
B. have their own function
C. are all the same
D. do not have any function
Answer: B. Have their own function
Explanation:
Cells that perform a specific function in an organism are specialized. I also had the K12 test.
If an organism has more specialized cells, its cells B. have their own function.
Specialized cells are the cells that makeup tissues and make up the system that work together in our bodies.
Some examples of specialized cells that we've in our body include blood cells, nerve cells, and the reproductive cells. It should be noted that specialized cells have their own specific functions.
Therefore, when an organism has more specialized cells, its cells have their own function.
