Answer:Recombination occurs through
crossing over and independent assortment. The correct option is B
Explanation:
-Genetic recombination is the process by which two different DNA are disintegrated and recombined to form new pairs of alleles. The process of recombination also involves the breakage and rejoining of parental chromosome. It occurs during meiosis ( that is formation of sperm and egg cells) and it gives them the correct number if chromosomes). Recombination occurs in meiosis through:
- CROSSING OVER: this is when paired chromosome press together and break, each may swap a portion of its genetic material.
- INDEPENDENT ASSORTMENT: which is the chromosome invented from either the father or mother can sort into any gamete and this produces a tremendous genetic variation. I hope this helps, thanks!
Answer:
channels and chain-like structures
Explanation:
The plasma membrane contains channels that favor the transport of materials from both sides, i.e., from the intracellular medium to the extracellular environment. Membrane channels are a class of proteins that enable the passive transport of ions and chemical compounds by using the electrochemical gradient in both sides of the membrane. For example, channel proteins in the cell membrane known as aquaporins enable the transport of water across the cell membrane much more rapidly than by diffusion across this barrier.
Answer:
it is the kind of science where scientific knowledge is used to solve criminal cases and other stuff.
benefits:Forensic science technicians can derive deep personal satisfaction from knowing that their work is crucial to solving crimes and achieving justice. They receive respect from the public for their expert knowledge, for example when testifying in court.
limits:Emotional and Physical Effects. Many of the crimes forensic scientists investigate involve violence. As part of their analysis, they may examine bloody clothing, study blood spatter and possibly view victims' bodies. In some cases, the bodies might be severely decomposed.
Life would be very hard because then they may not be able to survive <span />
