in order to increase chances of survival in a changing environment, it is important for a species to have
Answer:
One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.
Explanation:
The ___ of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The ___ of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, ____ either break or form.
Thus, water absorbs or releases a great deal of ____, helping to moderate temperatures.
Water is a versatile ____.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved ______.
Answer:
The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, hydrogen bonds either break or form.
Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.
Water is a versatile solvent.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.
Explanation:
The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.
Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.
Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.
The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.

Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?
Answer:
The correct answer is - Disruptive selection.
Explanation:
Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.
In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.

Answer:
word to my dead When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.

Choose the combination of factors that creates snow.
Answer:
Relative Humidity- Low
Air tempurature-cold
Air Pressure-low
Explanation:
High pressure, warm temperatures, and high humidity are factors that creates snow.
What are the factors that create snow?Snow and/or ice formation requires temperatures below freezing, both in the atmosphere and close to the ground.
Something that will induce the moist air to rise, forming clouds and precipitation, moisture, produces precipitation and clouds.
Water that has frozen solidly is snow, and the atmosphere (layer of gases around Earth) contains water in the form of vapor (gas). When there is a lot of vapor present, clouds develop, fill up with water droplets, and eventually begin to rain.
Therefore, when a very cold water droplet freezes onto a pollen or dust particle in the atmosphere, a snowflake starts to form.

Answer:
A. General Cell Processes
B. Growth
C. DNA Replication
Explanation:
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. So, the option A, B and C are correct.
What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Describe how organ systems interact to get oxygen to the cells
The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.
What is oxygen in the body?Our bodies require a specific amount of oxygen to function effectively since oxygen is necessary for life. When you breathe (inhale), oxygen enters your body through your mouth or nose and travels through your lungs into your bloodstream.
Oxygen inhaled by the lungs is also carried by your blood. Your body's other cells receive oxygen and nutrition from your circulatory system, which then collects any waste products they produce, including carbon dioxide, and transports them to your kidneys and lungs for elimination.
Therefore, the blood collects food nutrients from the small intestine and transports them to every cell in the body.
