It refers to genetic material taken up from the environment through bacterial cell walls.
DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.
All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).
Answer:
The phloem is responsible for transporting food from leaves to other parts of the plant.
The transport of pholem is bidirectional and changes the movement of particles according to the season. Generally, the transportation occurs in the direction of the source to sink but in spring season the direction is opposite that is from sink to source because the source and sink are n opposite sides. So in spring season, the stem tubers are sources and the growing leaves are sinks.
Answer:
Pelvic body cavity
Explanation:
There are four basic body cavities
The dorsal, thoracic, abdominal and the pelvic body cavity. For the question, the sperm can find itself inside the pelvic body cavity, the pelvic body cavity encapsulates the reproductive organs and the bladder. The reproductive organs then includes the vagina, uterus, and fallopian tubes (oviducts) etc. Thus, the sperm can pass through organs of the reproductive system in the pelvic body cavity.
Greenhouse gases warm the air near Earth’s surface by absorbing heat emoted by Earth.
