Answer: D
Explanation:
lIf the change in the ecosystem occurs, then it would effect the weather, temperature, and the abiotic factors. So, we can see that the bacteria could survive in any sort of temperature. So, A can't be it. Also, B can't be it because the grass can grow in any sort of soil, even if the soil is contaminated. C cant be it because even if the change in the envoriment (temperature, contaimination) kills of one of the brown bear's food source, they can still have other things they can eat. But, if the weather gets too hot or the soil gets contaimnated and kills off the ecalyptus plants, the koala has nothing else to eat. So, best answer is D.
DNA, cell membrane, cytoplasm, and ribosomes.
Both prokaryotic and eukaryotic cells have structures in common. All cells have a cell membrane, ribosomes, cytoplasm, and DNA. The cell membrane, or plasma membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
Answer:
G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.
The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.
Answer:
A surface wave is a wave that moves along the interface of two different materials, like air and water.
Explanation:
Answer:
The correct option is a) "decrease the amount of GTP to inhibit microtubule elongation and block secretion"
Explanation:
Since microtubules play a critical role in transporting secretory vesicles, preventing it from elongating will keep it from performing this function. Completely eliminating the microtubules from the cell as suggested in option d will harm the cells and other processes in it because the microtubules also have an integral part to play in maintaining cell shape & structure.
Hope that answers the question, have a great day!
