Thus, water absorbs or releases a great deal of_______ , helping to moderate temperatures. Because_______ is less dense than liquid water, it floats and protects lakes and oceans from freezing solid. Water is a versatile . Blood and other biological fluids are aqueous solutions with a diversity of dissolved .
Answer:
The correct words that film in the blanks are;
Polarity
Cohesion
Hydrogen bonds
Heat
Ice
Solvent
Solutes
Explanation:
Water is a highly polar molecule. Its polarity allows it to form strong intermolecular hydrogen bonds which accounts for the forces of cohesion in the water.
The hydrogen bonds form and break with evolution of heat hence accounting for the role of water in temperature regulation.
Ice is less dense than water due to spaces in the solid. Water is regarded as a universal solvent for polar solutes. Blood and other aqueous body clouds usually contains many dissolved solutes.

How does this equation represent the law of conservation of energy—that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
Answer:
Energy from the sun goes into making the sugar molecule. This energy is released to make ATP and heat.
Explanation:
6Co2+6H20->C6H12O6(glucose)+6O2(oxygen)
The sugar molecule is created by solar energy. This energy is discharged to produce heat and ATP.
What is the law of conservation of energy?
According to the rule of conservation of energy, energy can only be transformed from one form of energy to another and cannot be generated or destroyed.
This indicates that unless energy is introduced from the outside, a system always has the same quantity of energy. In the situation of non-conservative forces, when energy is changed from mechanical energy to thermal energy yet the overall energy does not change, this is especially perplexing. Energy must be changed from one form to another in order to be used.
In photosynthesis,
6CO + 6H₂O → C₆H₁₂O₆ + 6O₂
Sunlight is used for the light energy required to produce the sugar molecule.
Therefore, the law of conservation of energy is applicable in photosynthesis as energy from the sun is utilized by all living organisms.

What is dna replication?
Answer:
In DNA replication, cell machinery copies strands of DNA.
Explanation
DNAs, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides. These contain genetic information essential for growth, reproduction, and cell repair.
Nucleotide monomers are made up of, a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
Nucleotides, deriving their name from their nitrogenous bases, pair up to form base pairs. In base-pair formation, Adenine and Thymine form double bonds, while cytosine forms triple bonds with guanine...
DNA polymerase facilitates either DNA synthesis, by adding free nucleases to parent strands -these are first unwound and separated by helicases DNApolys synthesize DNA in 5'-3' direction; due to its restricted movement, there are only two modes of replication: continuous from the point of strand separation, the fork, and discontinuous from the fork. In continuous replication, DNApolymerase moves uninterrupted along the 3'-5 oriented template, adding nucleotides to the free hydroxyl group at its 3' end to produce the 5'-3' oriented leading strand. During the synthesis of the 3'-5' oriented lagging strand, DNApolymerase moves backwards along the template from the replication fork; DNA helicase separates the strands, and DNApoly's addition of nucleotides is periodically interrupted while forming discontinuous Okazaki fragments. Ligase enzymes assemble nucleotide strands of RNA and DNA -here, DNAligase assembles these fragments into continuous strands, producing two identical new helixes formed from a parent and newly replicated strand respectively.Which is it?? DNA, RNA, or Both??
1. Single-Stranded
2. Double-Stranded
3. Nitrogen bases

1. Explain how forces of attraction and repulsion exist within an atom.
Answer:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Explanation:
Answer:
1. Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.
2. Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.
3. Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.
4.
Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist: One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged. A positively charged cloud comes near a negatively charged cloud. A cloud with either a positive charge or a negative charge comes near the earth.Explanation:

The most basic definition of cellular respiration is that it is cells breaking down food to make energy. True or false?
Answer:
True
Explanation:
In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.
In cellular aerobic respiration:
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
Adaptations that help an organism survive appear quickly. True or False? And why
Answer:
false
Explanation:
is not worth it to do that
According to the theory of natural selection, features that may be passed down help animals adapt to their surroundings more successfully than their kin.
What condition that make organism adaptive?Adaptations are passable traits that improve an organism's capacity to endure and procreate in a given environment. An organism can manage in harsh settings, locate food and water, and protect itself by adapting.
This is the outcome of a process called natural selection. A species' nature gradually changes as a result of natural selection in order for it to fit into the niche.
If a species becomes extraordinarily well adapted to its habitat and the environment does not change, it can survive for a very long time before going extinct.
Therefore, it is false that, Adaptations that help an organism survive appear quickly.

Does anyone have an answer for this???
Answer:
because the truck is moving
Explanation:
the force of the engine is bigger than the fractional force so the truck keep moving and do not stop.
Answer with Explanation:
The forces are unbalanced because the engine force (bigger force) and the friction force (smaller force) are not equal. Their difference in force is 40 N. This makes the truck move forward or in the direction of the bigger force. Its movement is being slowed down by the friction force.
Both of the forces are acting in opposite directions, but they are not equal in magnitude. Such occurrence can make an object either slow down or speed up. It could also change its direction. This is in accordance to "Newton's First Law of Motion."

How do you think the body processes monosaccharides differently than polysaccharides? Would they take the same amount of time to digest and harvest energy?
Answer:
Polysaccharides from cell walls make up the fiber humans eat, while monosaccharides provide the sweetness in foods. As humans eat, chewing breaks down polysaccharides into smaller particles that eventually, through digestion, yield up the simple monosaccharides that can pass into the bloodstream.

Make a prediction of this: A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The scientists pointed out that because beets grow underground, they continue to grow in freezing conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter. To test this hypothesis, the scientists froze equal volumes of water on two separate plates. They spread an extract of beet roots on one plate of ice and sprinkled an equal amount of salt over the other plate. After keeping both plates at 0°C (the temperature at which water freezes) for a period of time, they measured the amount of melted water on each plate. Their results showed that the plate treated with beet extract contained more liquid water than the plate treated with salt.
Answer:
extract of beet roots could be used as antifreeze for water systems
Explanation:
In science, a prediction can be defined as a plausible conjecture that is subsequently proved (or rejected) using the scientific method. In other words, a prediction is the expected result obtained if the hypothesis is true. Scientists make predictions based on falsifiable hypotheses which can be tested through experimental and/or observational procedures. In this case, it could be predicted that the extract of beet roots could be used as anti-freeze for water systems in cold climates.
