Answer: They may be prokaryotic is false.
Explanation:
Protists are eukaryotic organisms i.e they have membrane bound organelles and Nucleus. They are neither plants,animals or fungus. Protists have many form of nutrition and they may be aerobic or anaerobic.
Some protists photosynthesized like algae while others are heterotrophs
They may be unicellular or multicellular.
Some protists have cell walls while others don't.
Explanation:
sustainable Forest management is like how paper companies cut down trees but they sustainably do it. By however many trees they cut down they plant however many more.
Answer:
The mechanism by which cells regulate their ability to respond to extracellular messengers is known as receptor signalling.
Explanation:
Cells senses an environment and communicate which each other through ligand-induced activation of signalling receptors at the cell surface. Signalling receptors enter the endocytic pathway and are sorts into various compartments. Endocytosis regulates cell signalling by controlling the number of receptors available for activation in plasma membrane and activation of receptors or downstream effectors often stimulate receptor endocytosis.
Answer:
e) directional selection
Explanation:
Directional Selection:
- The type of natural selection that favors one of the extremes of the phenotype spectrum, shifting the allele frequency to one direction
- This type of selection selects against intermediate and one of the extreme phenotypes.
- In this particular case, the increasing pollution has pushed the plants to evolve better acid tolerance.
- This indicates that if the environmental conditions worsen, only the acid tolerant plants will be able to survive.
* Another example is illustrated in the image. The graph shows the shifts in allele frequency.
Answer:
the following picture attached will help you
Explanation:
DNA makes RNA makes proteins
it starts with the relpication process above it, it will be DNA then it does a transcription process to mRNA(RNA) and then the last process called translation process into Proteins....
Hope this helps!!!
