In the vacuum of space there is no molecules. Sound waves get to your ears by bouncing off of molecules in the air. No molecules in space's vacuum means sound waves have nothing to bounce of off so they can not reach our ears meaning we hear no sound.

In sexual reproduction, traits will be taken from both parents, so the child will be a mix of traits from the father and the mother

In asexual reproduction, there is only one parent, so the child will be a genetical replica of the parent

The fertilization of ovules from Plant Q by pollen from Plant R results in the production of seeds. What percent of the genes in
blagie [28]

Answer:

The correct answer is - option A. 0%

Explanation:

The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.

The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.

g The Electron Transport Complex (ETC) consists of four proteins. How many of these proteins directly contribute to the proton g
vladimir2022 [97]

Answer:

Three proteins directly contribute to the proton gradient by moving protons across the membrane

Explanation:

The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.
