Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
Answer:
Explanation:
The first one is Prostista: Since they are mostly unicellular and are classified as eukaryotic.
The second one is Eubacteria: Since all Eubacteria has peptidoglycan in their cell walls.
The Last One is Achaebacteria: They tend to help in digestion which is a very acidic environment and fit the other two criteria
Answer
Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.
Explanation
Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.
Answer:
Cellular respiration involves many reactions in which electrons are passed from one molecule to another. Reactions involving electron transfers are known as oxidation-reduction reactions (or redox reactions).
Antibiotics stop the bacteria growth, reproduction or destroy the bacteria.
Explanation:
Antibiotics are known as those popular medicine which is helpful and also can fight for certain type of infection. Their main role is to stop their growth, reproduction or otherwise destroyed it.
The first antibiotics was penicillin. Antibiotic is using to stop the allergic reaction but it must be prescribed by doctors. Antibiotics also have side effects. Due to excess use of antibiotics abnormal blood clotting happens.
