37) Which of the following statements is correct about passive diffusion?

A) It requires an expenditure of energy by the cell.

B) It is a process in which molecules move from a region of higher
concentration to a region of lower concentration (or down a
concentration gradient).

C) It is a process in which molecules move from a region of lower
concentration to one of higher concentration (or up a concentration gradient).

D) It may require a transport protein.

E) It involves movement of molecules down a concentration gradient
and may require a transport protein.

Mitochondria | BioNinja

Mitochondria | BioNinja – Mitochondria are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis. They have a double membrane structure (due to vesicular coating as part of the endocytotic process). They have their own DNA (circular and naked) and ribosomes (70S)….about mitochondria is correct? a) Mitochondria are found in both eukaryotes and prokaryotes. b) There tend to be more mitochondria in fat cells Which of the following facts supports the claim that mitochondria developed from bacteria that, long ago, were incorporated into eukaryotic cells by the…Which of the following is NOT found or observed to occur in both mitochondria and prokaryotes? If cells are grown in media containing amino acids labeled with radioactive nitrogen (15N), most of the radioactivity will be found in the cells'.

Which of the following statements about mitochond – Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA . Prokaryotes do not have a nucleus. Instead, their genetic material is located in the main part of the cell. Prokaryotic Cells.Which of the following do you typically see as you move to deeper layers in a ConvNet? nH and nW increases, while nC decreases. In order to be able to build very deep networks, we usually only use pooling layers to downsize the height/width of the activation volumes while convolutions are used with…Which of the following correctly lists the order in which cellular components will be found in the pellet when homogenized cells are treated with The Golgi apparatus has a polarity or sidedness to its structure and function. Which of the following statements correctly describes this polarity?

Which of the following statements about mitochond

Practice For Exam 1 Microbiology Flashcards | Quizlet – 1) Which of the following statements is INCORRECT regarding prokaryotic cells? 36) Which of the following is NOT found or observed to occur in both mitochondria and prokaryotes?Genetic code Because prokaryotes lack membrane bounded organelles (mitochondria)Prokaryotes have circular DNA without histone Prokaryotes lack nuclear membrane … Eukaryotic and prokaryotic cells both use deoxyribonucleic acid (DNA) as the basis for their genetic information.Mitochondria – Mitochondria are oblong shaped organelles that are found in the cytoplasm of every eukaryotic cell. In prokaryotes, the membrane is the inner layer of protection surrounded by a rigid cell wall. Eukaryotic animal cells have only the membrane to contain and protect their contents.
