Sally conducts an experiment measuring plant growth. She finds that after two weeks, a plant that receives water grew 4 cm, but the plant that received soda died. What is the term for what is being measured?
Answer:
The correct answer is - the dependent variable.
Explanation:
In any study or research, the variable is that measured or affected by the change occurs lace in an experiment is called the dependent variable. The dependent variable depends on the factors or the variables that are changed in the experiment.
In this particular study, the variable which is measure is the height or growth of the plant which depends on the change in the hydrating supply so the dependent variable will be - the growth of the plant.

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.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 in plants. When water warms or cools, either break or form. 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.
Sea floor spreading happens in which plate boundaries?
Answer:
Divergent plate boundaries.
Explanation:
"As upwelling of magma continues, the plates continue to diverge, a process known as seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre".

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.

which structure makes proteins using instructions from the nucleus
Answer:
ribosomes
Explanation:
Ribosomes are small particles of RNA and protein found throughout the cytoplasm. Proteins are assembled on ribosomes. The nucleus gives coded instructions to the ribosomes, so they know what proteins to build.
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.

Trilobites appeared approximately 521 years ago and disappeared approximately 250 million years ago. During which era did the trilobites live?
a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These
Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.
Answer/Explanation:
It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

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.
