Answer: They are all genetically tractable

Explanation:

Yeast, fruit flies, nematodes, mice or the small plant Arabidopsis have known genome i.e their entire genetic information is known to the scientific community, thus they are EASILY MODIFIED in genetic research.

Also, they are simple eukaryotes (having cells with defined nucleus) so they can explain the processes in the human eukaryotic cell during genetic research

Both reasons make them genetically tractable

Which scenario would result in a decrease in population size, or a negative population growth?
wariber [46]

40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate would result in decrease in population showing negative population growth.

Explanation:

Negtaive population growth is a term used when individuals leaving the population is more than new individuals in the population.

Individuals would leave the population by two means:

either they die or emigrate from other places to join in.

The following scenario will be analysed by the formula provided to know the negative growth in population:

population growth = (birth rate + immigration) - (death rate + emigration)

putting the values in the equation:

first case:

immigrated individual = 14

emigrants = 0

new born = 14

died = 14

population growth = (14+14)-(14-0)= 14

second case:

immigrants = 28

emigrants = 40

new born = 10

died = 0

population growth= (10+28)-(0+40)= - 2

third case:

immigrants = 0                                                

emigrants = 12

new born = 17

died = 5

population growth = (17 +0)-(5+12) = 0

fourth case:

immigrants = 0                                                

emigrants = 19

new born = 25

died = 4

population growth:(25+0) - (19+4) =3

In second case the population growth has become negative. The value of population growth is -2.

The length, width and height of the given cell is 4mm. find the surface are of the cell
jenyasd209 [6]

Answer:

96mm

Explanation:

alright so since it had length, width, and height pf 4mm i guess it's a cube cell. the formula for the surface area is just n^3 (literally n cubed, easy to remember) where n is the length/width/height. 4mm^3=96mm, so the surface area of the cell is 96mm.
