Answer:
Surface area of the cube = 6cm²
Volume of the cube = 1cm³
Explanation:
The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:
S.A = 6 × a²
That is; a² + a² + a² + a² + a² + a²
Where;
a = length of a side of a cube
a² = area of one side of a cube
Note that, a cube has 6 faces
According to this question, a cube has a length of 1cm on each side.
Hence, S.A = 6 × 1²
S.A = 6 × 1
S.A = 6cm²
Volume of the cube can be calculated using the formula: a³
Where a = 1
Volume = 1 × 1 × 1
Volume = 1cm³
Answer:
b) electron transport chain
Explanation:
During sprinting, muscles need a constant supply of ATPs (the energy currency of cells) to support the continuous movement. The electron transport chain is present in the inner mitochondrial membrane.
Oxidation of NADH and FADH2 through electron transport chain produces proton gradient across the membrane which in turn drives the synthesis of a large number of ATPs to support sprinting.
Answer:
Cells make RNA messages in a process similar to the replication of DNA. The DNA strands are pulled apart in the location of the gene to be transcribed, and enzymes create the messenger RNA from the sequence of DNA bases using the base pairing rules
Explanation:
Answer:
An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.
