Answer:
Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.
Explanation:
A paper mill located on a coastal region of Florida experienced an accident in which a large portion of toxic waste from the plant leaked into the ocean. This waste contained dioxins which affect animal health and the environment. The company cleans up the waste and the state requires that they hire an ecologist for the next 10 years to monitor the area.
Which statement best explains why the state required the company to hire an ecologist?
Group of answer choices
The state wants to be sure there are not new, mutated species.
The state needs to ensure the company spent enough money restoring the ecosystem.
The state wants to see if the spill will have a continued impact on biodiversity.
The state needs to be sure the company will not be sued by an environmental agency.

How is DNA created?(short answer)
Explanation:
For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides. Nucleotides are made up of three main parts, a sugar group, a phosphate group, and some type of nitrogen base. Hope this answers, and is helpful! Have a great day! :))

what type of mutation has the least amount of impact on a protein ?
Answer: Silent Mutation
Explanation: Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.
Answer:
Point Mutations
Explanation:
It is the least harmful mutation

How is the cycling of water driven by gravity and the sun
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. ... Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff.
How water resources are being polluted and how can we conserve them ?

Birds have air sacs and lungs. When birds
breathe (in / out,) oxygen-rich air fills the
lungs and air sacs. When birds breathe
(in / out), the oxygen-poor air leaves the
lungs, and stored fresh air enters the lungs from
the air sacs. This means that birds always have a
supply of oxygen-(rich / poor) air.
How does meiosis create four daughter cells from one parent cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
Which sex chromosome determines the sex of a baby?

Explanation:
What is the solute potential (ΨS ) of a 3.0 M NaCL solution at 27°C under standard atmospheric conditions?
Answer:
149.58 bars
Explanation:
The solute potential (ΨS) of a solution is given by:
ΨS = iCRT
Where i = ionization constant of the solution, C = molar concentration of the solution, R = pressure constant =0.0831 liter bars/mole-K, and T = temperature in Kelvin.
NaCl dissociates in water to give Na and Cl ions, hence, i = 2
T = 27 + 273 = 300 Kelvin
C = 3.0 M
ΨS = 2 x 3 x 0.0831 x 300
= 149.58 bars.

The given question provided the data of an experiment to determine the effect of water temperature on the amount of sugar that dissolves in a beaker of water and asked to identify the components:
Amount of Water (mL) - constantThe temperature of Amount of Sugar - constantThe Temperature of water (°C) - variableAmount of Sugar dissolved (g) - variableIn any research investigation or experiment, there are three main parts that are:
Independent variable: These are the variables that are manipulated or change to see the effect on the dependent variable, these are manipulated by the researcher. In this investigation, the independent variable is the temperature of the water as it affects the amount of sugar that dissolves.Dependent variables: these are the variable that also changes due to change and according to the change in the independent variables. In this investigation, the amount of sugar that dissolves changes according to the change in the temperature of the water, thus, its dependent variable.Constant or control: these are the parts that do not change during the experiment so there is no other influence occur in the Dependent variable.Thus, the correct answer is -

6. Asparagine and Methionine are what type of molecule?
Answer:
Asparagine is the amide of aspartic acid. The amide group does not carry a formal charge under any biologically relevant pH conditions. The amide is rather easily hydrolyzed, converting asparagine to aspartic acid. This process is thought to be one of the factors related to the molecular basis of aging.
