Silver is a better conductor than aluminum. If a silver wire and an aluminum wire have the same length and the same thickness, w
GenaCL600 [577]

Answer:

Between silver and aluminum wires of same thickness and length, silver will offer lesser resistance.

Explanation:

Aluminum will offer higher resistance than silver (both having same thickness and length).

Silver has lesser resistivity than aluminum.

Resistivity is directly proportional to resistance.

Thus, between to wires of distinct materials, one with higher resistivity will offer greater resistance.

Which organelle is found in both plants and animals:
MrMuchimi

Answer:

The correct answer is E. The organelle that is found in both plants and animals is the Mitochondria.

Explanation:

Mitochondria are cellular organelles responsible for supplying most of the energy necessary for cellular activity (cellular respiration). They act as energy plants of the cell and synthesize ATP at the expense of metabolic fuels (glucose, fatty acids and amino acids). The mitochondria has an outer membrane permeable to ions, metabolites and many polypeptides. This is because it contains proteins that form pores called porins or VDAC (voltage-dependent anionic channel), which allow the passage of molecules up to 10 kDa of mass and an approximate diameter of 2 nm.

Which of these is a polysaccharide? A. Lactose. B. Glycogen. C. Sucrose.
geniusboy [140]

cellulose is a polysaccharide.

A significant class of biomolecules is polysaccharides. They are large chains of monosaccharide molecules that are linked together. These intricate biomacromolecules serve as a vital energy source for animal cells and are a crucial part of plant cells' structural makeup. The nature of the monosaccharides determines whether it is a homopolysaccharide or a heteropolysaccharide.

A branching polysaccharide is a type of carbohydrate that is different from a linear polysaccharide, which is a straight chain of monosaccharides.

Organisms have this energy in reserve. The molecules are hydrophobic because water cannot enter them because of the many hydrogen bonds present. They permit adjustments to the concentration gradient, which affects how the cells absorb nutrients and water.
