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: Mitochondria and Chloroplast have double membrane(inner and outer) but golgi apparatus and endoplasmic recticulum have single membrane.
Explanation:
Mitochondria is referred to the power house of the cell where energy is produced.
Chloroplast is the organelle found in green plants use for photosynthesis to produce energy. Both chloroplast and mitochondria are found in multicellular organisms and their function is to produce energy. The both have double membrane bound organelles.
Golgi apparatus and endoplasmic reticulum are single membrane bound organelles and they are found in eukaryotic cells. The endoplasmic recticulum transport synthesized protein to vesicles of Golgi apparatus.
Answer:
microscopic and unicellular, with a relatively simple cell structure Bacteria are the most abundant of all organisms.
Answer:
1) Deforestation has real consequences for animals. The most serious impacts of deforestation on animals are listed below. #1 Habitat loss Deforestation can lead to a direct loss of wildlife habitat as well as a general degradation of their habitat.
2)When there is less soil stability because of the disadvantage of erosion, the risk of a flooding event occurring during the rainy season increases dramatically. Poor water absorption levels make it easier for higher accumulation levels since the trees are no longer present to take up the extra moisture.
