Answer:
S phase of the cell cycle
Explanation:
During Mitosis, DNA is replicated during the S phase (Synthesis phase) of Interphase.
That would defined having a concussion
Answer: Kaylan
Explanation: Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Which makes it harmful towards the environment.
Answer:
Facilitated diffusion
Explanation:
Oxidative phosphorylation, involving the Electron transport chain and Chemiosmosis is the third stage of cellular respiration. The main purpose of the ETC is to build an electrochemical (electrical and concentration) gradient across the inner mitochondrial membrane. It does this by using energy to pump protons (H+ ions) from the matrix to the inter-membrane space of the mitochondria.
Facilitated diffusion, also known as passive transport through channels, is a form of facilitated transport involving a passive movement of molecules along their concentration gradient, through channels called membrane proteins.
During Chemiosmosis of Oxidative phosphorylation, protons (H+) flow back down their concentration gradient (from inter-membrane space to matrix) due to the chemiosmotic gradient that has been formed in ETC. However, hydrogen ions (H+) cannot pass through the inner mitochondrial membrane except through an enzyme (protein) found in the inner mitochondrial membrane called ATP synthase. This protein acts as a machine powered by the force of the H+ diffusing through it, down an electrochemical gradient. This movement of H+ via ATP synthase further catalyzes the conversion of ADP to ATP.
It is an example of facilitated diffusion because H+ ions are diffusing across the inner mitochondrial membrane (from inter-membrane space to matrix) via a protein channel or membrane protein called ATP synthase.
Answer:
Since variations in air pressure drive the winds on Earth, isobars also give meteorologists an easy way to assess wind direction and speed. Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase.
