Answer:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.
Explanation:
Angiosperms can use Insects animals and wind but not water.
so your answer is water.
Answer:
B. the action of microRNAs that block translation of specific mRNA molecule
C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.
Explanation:
RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.
MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.
RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.
Answer:
Both have two circuits for circulation.
Explanation:
- The two circuits of circulations are known as the systemic circuit and the pulmonary circuit.
- In the<u> systemic circuit</u> oxygenated blood from the heart is pumped to all parts of the body through the blood vessels and then the blood is pumped back to he heart.
- In the<u> pulmonary circuit</u> deoxygenated blood from all parts of the body is pumped from the heart to the lungs to be oxygenated and after it is oxygenated it is pumped back to the heart.
