Answer:
Asexual reproduction occurs in fungi by budding, spore formation and fragmentation.
sexual reproduction occurs in fungi by fusion of two gametes to produce a zygospore.
Explanation:
Fungi reproduces both sexually and asexually in-other to allow them adapt to any environmental conditions.
ASEXUAL REPRODUCTION
Almost all fungi reproduce asexually by spore formation. a single parent fungi produces spores that are genetically identical to itself. the spore produced can then develop into new fungi without fertilization.
SEXUAL REPRODUCTION
Sexual reproduction in fungi occurs when two haploid gamete fuse together to produce a Zygospore. zygospore is always genetically different from parent.
Answer:
This observation is True
Explanation:
Membrane integral proteins can function as ion channels during the transport of molecules through the membrane. Moreover, integral proteins can also act as pores for the transport of specific molecules between both sides of the membrane, ion channels that mediate effector signals, signaling transduction mechanisms capable of amplifying cellular responses and hormone receptors.
A mutation is a permanent change in the DNA sequence of a gene. This can be beneficial if the change gives a new function to or improves the function of that gene.
<span>The above is a definition. But one must really define "beneficial". Some regard it as beneficial if it helps the specific individual who has it. Others would think it beneficial if it produced some survival advantage that insured more descendents for that individual. </span>
<span>It is the difference between a mutation that allowed for greater athletic ability, but a decreased desire for offspring, versus a more moderate athletic enhancement, but a greater desire for offspring. </span>
<span>The small percentage of ways to improve an organism, versus the near infinite ways of harming the organism, mean that most mutations are not going to be beneficial. At best, they will be "inconsequential" - such as a new shade of eye color, or a mole on a section of your skin. </span>
The populist notion of "powers" that can come from mutations is wildly inaccurate. Even assuming a minor power like the ability to see infra red radiation would take thousands upon thousands of mutations over vast amounts of time. A mutation for blindness is far more likely.
<span>It should also be noted that the traditional model of evolutionary theory no longer applies to man. We don't allow changes in our environment, and without such changes, there is no need for one trait more than another to predominate. After all, it is irrelevent that a mutation might allow for greater speed in running, when everyone drives a car.</span>
