There are four organelles that are involved in protein synthesis. Those are the following: Nucleus ribosomes, the rough endoplasmic reticulum and the Golgi apparatus, or the golgi complex. All four work together to synthesize, package and process proteins. Protein synthesis begins with DNA.
Answer:
Plants have a <u>cell wall</u> which gives the plant structure. The cell wall is made of cellulose.
Explanation:
Answer:
a. ciliary body: focus the pupil
Explanation:
The choroid thickens behind the iris and forms the circular ciliary body. Ciliary muscles are present in the ciliary body. The lens is attached to the ciliary body by ligaments. The function of the ciliary body is to holds lens in place and to serve in accommodation.
When focusing on a distant object, the relaxed ciliary muscles make the lens is flat and the suspensory ligament is taut. When focusing on a near object, the contraction of the ciliary muscles of the ciliary body allows the lens to accommodate. The lens becomes rounded causing the suspensory ligament to relax. Thereby, the ciliary body regulates the shape of the lens for near and far vision.
Answer:
Wegener thought all the continents were once joined together in an "Urkontinent" before breaking up and drifting to their current positions. But geologists soundly denounced Wegener's theory of continental drift after he published the details in a 1915 book called "The Origin of Continents and Oceans." Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart.
Explanation:
Answer:
In the electron transport chain, when the protons move down their concentration gradient, the electrons are transferred from one molecule to the other and energy is released.
Explanation:
During the rear stage of cell respiration or oxidative phosphorylation two processes are involved. Among which one is the electron transport proton gradient chain, in which protons are transferred from one to the other molecule.
In this process electron also releases energy to make an electrochemical gradient. In this chain oxygen accepts protons and chooses electron to produce water.
