How is tonicity affected by solutes?
Unlike osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an effective osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always equilibrate with equal concentrations on both sides of the membrane without net solvent movement.

Eukaryotic cells are enclosed in the membrane, and the nucleus is bound by a nuclear membrane. Major parts of the eukaryotic animal cell are the nucleus, cytoplasm, mitochondria, Golgi, ER, etc.
What are animal cells?Animal cells are eukaryotes that lack cell walls but have almost the same components as plant cells. The cytoplasm is the component of the cell where all the organelle lies.
The nucleus is the central organ that is involved in genetic replication and transcription and translation. Mitochondria are involved in the metabolic process and release of energy.
Golgi are involved in the packaging and transport of the proteins and ER produces proteins that are transported to the Golgi. Vacuoles though are present in small quantities they aid in the accumulation and elimination of the waste product.

Which atom has two unpaired electrons in the outer valence
shell?
O helium
hydrogen
Oxygen
Olithium
Answer:
Oxygen
Explanation:
The electrons present in an atom are arranged in shells or orbitals. The electrons are filled into these shells based on their energy levels with those shells closest to the nucleus filled first as they have the lowest energies.
The arrangement of electrons around the nucleus of an atom is known as electronic configuration. The outermost electron shell of an atom is known as a valence shell shell and the electrons found in this shell are known as valence electrons. The electrons usually exist in pairs. The first shell can only contain two electrons; the second shell can contain 8. the electrons are singly filled first before pairing occurs.
The electronic configuration of the atoms of the elements in the option are as follows:
Helium : 1s² ; valence electrons are 2 which are both paired
Hydrogen: 1s¹ ; valence electron is 1
Oxygen : 1s²2s²2p⁴ ; valence electrons are 6 wit two unpaired electrons
Lithium : 1s²2s¹ ; valence electron is 1
Helium has two valence electrons but they are paired as its 1s shell can only contain a maximum of two electrons.
Oxygen has 6 valence electrons. Two of these electrons are paired while the other two are unpaired.
11- El Pirata Barba Plata ha llegado a la isla del Coral para buscar un
tesoro. En el mapa pone que, desde la orilla, debe recorrer 3,7 hm a la
pata coja hacia el centro de la isla, y después otros 8,5 dam dando
volteretas en la misma dirección. ¿Cuántos metros recorrerá en total
desde la orilla hasta el tesoro? * cuál es la repuesta
Answer:
El pirata recorrerá 455 metros
Explanation:
3,7 hectómetros (hm) = 370 metros (m)
8,5 decámetros (dam) = 85 metros (m)
>> Distancia en metros = 370 m + 85 m = 455 metros
El hectómetro (hm) es una unidad de longitud que equivale a 100 metros, donde el prefijo hecto indica la equivalencia a 100 metros. Por su parte, el decámetro (dam) equivale a 10 metros, donde el prefijo deca indica la equivalencia a 10 metros.

The third time he plays Taylor Swift. When he plays Taylor Swift, Maggie immediately and starts to smile. •What is the independent variable? •What is the hypothesis? •What is the dependent variable? •Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all. What is this called?
Answer:
Independent variable: THE TYPE OF MUSIC PLAYED
Dependent variable: MAGGIE'S TEARS
Hypothesis: IF Taylor Swift's music is played, THEN Maggie will stop crying
Control group
Explanation:
The hypothesis of an experiment is a testable explanation given to possibly solve an observed problem. In this question, Maggie thinks Taylor Swift's music will get Maggie to stop crying, hence, one can hypothesize that: IF Taylor Swift's music is played, THEN Maggie will stop crying
Independent variable is the variable that the experimenter manipulates or changes in order to bring about an outcome. The independent variable in this experiment is the THE TYPE OF MUSIC PLAYED by Bart because it is what is changed.
Dependent variable is the variable that is being measured. It responds to the changes made to the independent variable. In this experiment, the dependent variable is MAGGIE'S TEARS.
Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all, this is called the CONTROL GROUP because the control group of an experiment is the group that does not receive any experimental treatment i.e. the independent variable is not added.

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did the elephant population decline over this time period? (Show your work.) How does this compare to the change in range over this same time period?
Answer:
The initial amount, 1.3 million = 1,300,000 is the 100%.
now, 640,000 is a given percentage (lower than 100%) of that.
How we can find it?
suppose that 640,000 represents an x%.
Then we have that the quotient between the actual quantities and the percentages must be the same
(640,000/1,300,000) = x%/100%
x% = (640,000/1,300,000)*100% = 49.23%
Then the percentage declined is:
100% - 49.23% = 50.77%
The other question can not be answered with the given information.
In order to calculate the percentage decline over the period of time between 1979 and 2007, the general formula for percentage change will be applied. This is as follows:
[tex]\frac{B-A}{A} \times 100[/tex]
where:
A = final value
B = initial value
In this problem:
A = Initial population = 1,300,000
B = Final population = 640,000
Applying this formula to the problem, the percentage change in population between 1979 and 2007 is as follows:
[tex]\frac{B-A}{A} \times 100\\\\\frac{640,000 - 1,300,000}{640,000} \times 100 \\\\\frac{-660,000}{1,300,000} \times 100\\\\= \frac{-66,000,000}{1,300,000} \\\\= -50.769 \%\\= 50.77\% \\Note\ that\ the\ minus\ sign\ denotes\ a\ decline.[/tex]
B: The change in range over this period of time is the difference between the final population and the initial populations, which is calcalated thus:
B - A (as explained above)
= 640,000 - 1,300,000 = - 660,000 (the minus sign still shows a decline)
While the percentage shows a "relative change" in terms of percentage, the change in range shows an absolute or actual change.

Which of the plant groups is the control group?
Answer:
plant group 1
Explanation:
Because, it is the only one that has not gotten fertilizer
The plant group that is the control group is plant group 1.
What are fertilizers?Any substance of earthy or man-made origin applied to soil or plant tissues to provide plant nutrients is referred to as fertilizers. It's possible to distinguish fertilizers from spreading agents.
The biology student is studying the effect of fertilizers on plants. Fertilizers increase the growth of the plant, and they also affect the soil of the plant in which they grow.
There are three groups of plants that are used. The growth of the first plant is O and 3.0. The growth of the second plant is 5, 3.2, 3, and 10 and the growth of the third plant is 10, 4.4, 20, and 5.0.
By seeing the Table, we can assume that the growth of plant group 1 is most affected and all other plants have similar.
Thus, the plant group is 1.
