Answer:

False

Explanation:

Gram stain technique is a method use to classify bacteria into large groups base on their different cell wall components. It differentiate gram positive and gram negative by coloring them with red or Violet colors.

Gram stain is use for identification and classification of bacteria.

Gram positive stain violet due to presence of thick layers of peptidoglylcan in their cell walls and gram negative stain red due to thin layers of peptidoglylcan in their cell walls.

What is the relationship between genes DNA and proteins
Law Incorporation [45]

Answer:

Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.

Hopefully, this answer helped! :D

I only need help with number 2 and 3 please answer both i mark you as brainlist
kakasveta [241]

Answer:

Reading graphs: The variable plotted on the x-axis is year while the two variables plotted on y-axis are both wolves and moose.

Interpreting variables: The population of moose rose from 800 to 1550 between 1965-1972 while the population of wolves rose from 24 to 43 between 1973-1976.

inferring: The change in population of moose might cause a change in wolves population as a result of the feeding pattern of wolves, perhaps the contest between them was affected by availability of another prey which allows the predator (wolves) to feed on another prey, hence increasing the population of moose.

Conclusion: The dip in population of moose between 1974 and 1981 could be attributed to voracious feeding pattern the predator (wolves) had on the prey (moose) which inturns allows the dip in population during the above mentioned years.

Predicting: If there is a disease infection in wolves, then there would be an increase in the population of moose the next year as a result of disruption in the predator-prey contest, hence; allows one to be more populated the following year.

Explanation:

From the above assertions, it could be deduced that only when the feeding pattern of the predator (wolves) changes then the population of the prey would either be reduced or increased.

Select the correct answer.
NemiM [27]

Answer:

i dont know exactly what characteristic it would be

Explanation:

the variation of the beak shape was because the islands had diffrences to them. so on some of the islands the nuts would be bigger or smaller. The birds had to adapt to this so their beaks changed when you looked at the diffrent birds on the diffrent islands. The finches would have big beaks on one island because the nuts were bigger and they need food, but on another island the nuts were smaller so the finches on that island would have a smaller and more narrow beak. so bassiaclly the diffrences were because the birds adapted over time so they could use their beaks to properly eat.
