Answer:

The correct statement is : Most prokaryotes live in communities

Explanation:

Electron microscopes are normally shows color of specimen in black and white. The part of the specimen passed through the electron appears white and rest of the part in black.

Flagella found in various microscopic organism such as protozoa, bacteria, archaea and some other eukaryotes for cell movement. Most of the prokaryotes are found in the colonies form however, these are unicellular entities but shows community formation. Plant cell does not require lysosomes as they have vacuoles for the function of lysosomes.

Thus, the correct statement is : Most prokaryotes live in communities.

An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?
Degger [83]

Answer:

An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?

Acceleration= velocity/time

velocity=5mm= 0.005m

time= 1 hour= 60 seconds

A= 0.005/60

Acceleration= 0.000083m/s square

balandron [24]
I would say A) Coevolution because the two species would evolve in response to one another. Flowers and their pollinators must evolve together. For example, if the flower has a mutation that no longer attracts the bumblebees, it will not reproduce. Then the hummingbird would have to find a new food source.

Which describes the variable that is changed to test the prediction
slavikrds [6]

D)independent

Explanation:

An independent variable is a variable that is changed to test the prediction in an experiment. Independent variables are the cause in an experiment. They are the ones that produces the effect.

  • Changing independent variables produces different effects in an experiment.
  • These effects are the dependent variables
  • Independent variables do not depend on the outcome of the experiment.
  • They are the ones that determines how a reaction proceed and what might likely happen.

Which choice lists the Linnaean taxons in the correct order from least specific to most specific?
Lorico [155]

Answer:

a) Kingdom, phylum, class, order, family, genus, species.

Explanation:

Kingdom is the broadest taxonomic category after domain as proposed by Linnaeus. The Linnaean hierarchy of taxon identifies species as the most specific taxon that include only those organisms that can interbreed to produce the fertile progeny.

Several species with some common features are placed in same genus while related genera are placed in same family. Likewise, related families are placed in same order and the related orders are placed in same phylum.

Hence, kingdom is the least specific or broadest taxon that includes all the related phyla while species is the most specific taxon that include only the organisms that can interbreed.

When the ATP synthase molecules are open, the hydrogen ions move out of the thylakoid. How does the cell use the kinetic energy
morpeh [17]

The synthesis of ATP is based on energy conversion, via conformational changes of the subunits.

A proton gradient on either side of the membrane into which the ATP synthases are inserted is necessary for their operation, which implies that the synthesis of ATP can not be done independently of a membrane. Within the mitochondrial inner membrane, it is the respiratory chain that provides the pH gradient by injecting protons into the intermembrane space during the transfer of electrons from one complex to another. At the level of the thylakoid membrane, it is the photosynthetic chain that injects protons into the lumen.
