Answer:
The correct answer is-forcing blood from the heart into the major arteries
Explanation:
Heart is not made up of smooth muscles rather it is mainly made up of a specialized type of muscle called cardiac muscle which helps in the contraction of heath that results in the forcing blood from the heart into the major arteries.
Cardiac muscle is straited muscle but smooth muscle is not straited muscle. These smooth muscles are mainly present in the organs which have hollow walls like urinary tract, digestive tract, blood vessels, etc.
Therefore forcing blood from the heart into the major arteries is not a function of smooth muscle tissue.

Answer:
Explanation:
1. mRNA (messenger RNA): Produced during transcription. Carries the genetic instructions of a gene from the nucleus to the ribosome in the cytoplasm.
2. rRNA (ribosomal RNA): Together with proteins, composes the ribosome, the organelles that are the site of protein synthesis.
3. tRNA (transfer RNA): Brings the correct amino acid to the ribosome during translation.
The answer is true about the plant cell
Answer:
d. recessive epistasis
Explanation:
Recessive epistasis is a genetic phenomenon where the recessive gene is able to repress the expression of the dominant gene, presenting a greater number of individuals with the recessive genotype, in the F2 generation, than the number of individuals of the dominant genotype.
An example of this can be seen in the question above, where the F2 generation contained 178 purple, 60 red and 80 white flowers. The white color represents the recessive allele, while the red color presents the dominant allele. The recessive allele was expressed in greater quantity indicating the occurrence of recessive epistasis.
