Precipitation is one of the main processes involved in the water cycle. It involves the formation of water falling to the ground from clouds and transforming into either rain, snow, sleet, or hail. Which of the following properties of water can be used to explain why when water falls from clouds it is able to form a rain drop? *
A. cohesive ability
B. universal solvent
C. expansion upon freezing
D. moderation of temperature
Answers
Answer: A
Explanation: Hydrogen bonds between the water molecules on the liquid surface are relatively strong and pull on each other more than air molecules. This bond strength results in surface tension that tends to minimize the liquid surface area and produce a spherical raindrop.
Precipitation is the one of the main processes in the water cycle. It involves the formation of clouds and transforming into either rain, snow, sleet, or hail. This is possible due to the property of cohesive ability of water molecules. Thus, the correct option is A.
What is Precipitation?
Precipitation is one of the main processes involved in the water cycle. It is the liquid or frozen water which forms into the atmosphere and falls back to the Earth in the form of rain, sleet, snow, or hail. It comes in many different forms. Along with the evaporation and condensation of water, precipitation is one of the three major parts of the global water cycle.
Precipitation is achieved by the cohesive ability of the water molecules which explains the formation of clouds and rain drops. Cohesive forces are responsible for binding the compounds together such as a rain drop containing water molecules.
Therefore, the correct option is A.

When a trait is shown and at least one letter is upper case.
A) dominant
B) recessive
C) trait
D) allele
Answers
Answer:
maybe trait?
Explanation:
dunno lol
Answer:
When a trait is shown and at least one letter is upper case, it is a dominant allele (option A).
Explanation:
In genetics the presence of a dominant allele - represented by a capital letter - is sufficient to suppress a recessive allele, expressing the dominant trait in the phenotype.
Dominance is based on allelic combinations of the genotype, which are expressed in the phenotype for a given characteristic:
Two dominant alleles (AA) express the only possible trait, dominant.One dominant allele and one recessive allele (Aa) show a dominant phenotype, as the former suppresses the latter. It is a hybrid or heterozygous.Two recessive alleles (aa) show a phenotype with the recessive trait.The other options are not correct, because:
B) Recessive is the allele that is only expressed in the phenotype when there is a pair in the gene.
C) Trait is equivalent to a characteristic.
D) Allele represents the different ways in which a gene is expressed.

Which of these is a benefit of naturally occurring forest fires? A) They spread the seeds of some trees. B) They allow the forest to become dense. C) They cause the forest canopy to thicken. Eliminate D) They allow ladder trees to entwine with large trees.
Answers
Answer:
A
Explanation:
Here, we want to pick which of the options is a correct answer to being the benefit of naturally occurring forest fires.
The correct answer is that they help to spread the seeds of some trees.
Naturally occurring forest fires ravages the forest and thus work with wind force. They proceed through the entirety of the forest from the point in which they start.
By moving from a particular point in the forest to another point in the forest, they allow for the process of mass movement to naturally occur.
By translocation from one point to another, they take the seeds alongside with them and thus allows for the dispersal of these seeds through the forest

Ashes (which are made of carbon), carbon dioxide gas, water vapor, heat, and light are produced when wood is burned. Since this change cannot be undone, it is a chemical change. Since oxygen and hydrogen unite to create a single product, Thus option D and E is correct.
What is chemical changes?A chemical change is the transformation of one substance into another, the emergence of new compounds with distinct properties, or any combination of these.
It happens when two compounds mixes to create a new material (synthesis or either decomposes to form more substances).
Chemical synthesis, or, alternatively, chemical breakdown into two or more separate molecules, occurs when one material reacts with another to create a new substance.
These processes are referred to as chemical reactions, and they are typically irreversible barring additional chemical reactions.
Therefore, burning of wooden logs and formation of water is an example of chemical changes.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
solution. Which is the correct conclusion if the cell remains in the beaker for an
extended period of time?
Answers
Answer:
the animal cell will burst
Explanation:
If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.
Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.
Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
The reaction has one reactant and at least and at least two products

Some behaviors, such as nest building in birds, are determined by the genes of an organism. These innate behaviors are inherited from parent to offspring and exhibited even if the offspring does not observe its parent performing the behavior. Nest building behavior was most likely an evolutionary advantage because birds that built nests were more likely to raise their young to maturity and thus increase their reproductive success. That is, birds that laid their eggs in nests had more offspring survive to adulthood than those that did not. Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a species due to+

natural selection
Explanation:
According to the evolutionary theory, natural selection can be understood as the process of differential survival and reproduction of individuals due to phenotypic differences, which may be associated with different colors, sizes, behaviors, etc. The only prerequisite is that these phenotypic differential traits must be heritable, which means that they must be passed by genes from one generation to the next. For example, in the white-throated sparrow, it has been discovered two morphs that differ in behavior due to a chromosomal inversion in sex chromosomes.
four students drew different illustrations to show the flow of energy in a field ecosystem. Which of the illustrations below is most accurate?
Answers
The correct answer is the second illustration
Explanation:
Energy flows from one level or organism to another as one organism takes nutrients from another. In this context, the first level is plants including oats and these take nutrients from the sun and the soil to obtain energy. On the second level are herbivores including mice that feed on plants. These can be followed by other organisms such as carnivores, for example, foxes and even top predators. Finally, the last level is decomposers these include bacteria and other organisms that can obtain nutrients from plants and animals as they die and decompose.
According to this, the correct diagram is the second one because these shows accurately how energy flow from the sun to plants oats), then to animals (mouse), and finally the energy of plants and animals flows to the decomposers.
