The human body processes and eliminates food waste using the organs of the excretory system. Which organelle performs a similar function in humans at the cellular level?
Answer:
Lysosome
Explanation:
The lysosome is a part of the endomembrane system. It is a series of sacs containing digestive enzymes that are surrounded by membranes. Lysosomes are produced by the Golgi apparatus. They break down waste products so some components can be released outside the cell and others can be recycled.
Answer:
Signal transduction pathways
Explanation:
Plant hormones act by directly affecting the activities of signal transduction pathways.
Signal transduction pathways are involved in the transfer of signals from outside of the cell to the inside of the cell for the regulation of various cellular activities. For this, the extracellular signalling molecules bind to the receptors that are located on the cell membrane. After their binding due to some change in the receptor molecule, a signal is triggered in to the cell and thus information from outside of the cell is transferred to the inside of the cell through these transduction pathways.
Plant hormones affect these pathways and as a result membranes, enzymes, and genes are also influenced by the plant hormones.
Answer:
I agree it would be A) IT is a reactant in a chemical reaction
Explanation:
a catalyst is a substance that causes a chemical reaction to happen in a different way than it would happen without that catalyst
Answer:
The statement that is false is b)The nuclear envelope is continuous with the Golgi apparatus.
Explanation:
The nuclear envelope or nuclear membrane is not continuous with the Golgi apparatus; rather it is continuous with the exterior of the endoplasmic reticulum.
Nuclear envelope is a double-layered membrane built from lipid bilayer. The nuclear membrane consists of nuclear pores, which are made up of proteins and majorly function in the passing of selected substances in and out of the nucleus. Hence, all the other statements a,c,d are correct.
