Answer:

Sporangium (plural- sporangia)

Explanation:

ALTERNATION OF GENERATIONS between haploid state and diploid state is a vivid phenomenon in the reproductive life cycle of ferns. Both generations grow independently of one another. The sporophytic phase, which is the visible fern plant, produces a structure found on the underside of the Fern's leaves or fronds called SPORANGIA. They are usually in a group or cluster called SORI. These sporangia produces haploid spores by meiosis. The spores are released and they germinate into a gametophyte.

The gametophyte produces haploid sperms (from antheridium) and haploid eggs (from archegonium) which fuses in a process called fertilization to produce a diploid zygote. The zygote undergoes mitotic growth to develop into embryo which subsequently becomes the sporophyte (fern plant). The cycle repeats continuously when the sporophyte produces spores on its SPORANGIA again.

The right answer is C. The offspring are genetically distinct ... by sexual reproduction.

Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.

In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).

storchak [24]

Answer:

The government should not go ahead with this plan.

Explanation:

If the government decides to proceed with its plan to pass a law that authorizes the management of a hospital to force people who refuse to wash their hands out of a hospital and deny them medical care against their will, then the government will be infringing on people's right to life. While it is necessary to prevent the spread of Clostridium Difficile (C. difficile) , any law that is made to that effect must not abuse the right of access to medical care which is a fundamental right of citizens. This action will be ethically incorrect because it amounts to a government using a high handed approach in discharging its duties.

However, the intention of such a law is to protect the citizenry from the bacteria Clostridium Difficile (C. difficile) . If such a law is not passed, more people may become infected by the bacteria owing to the carelessness of other people. This situation is made worse because the organism is resistant to antibiotics.

However, since prevention of the spread of Clostridium Difficile (C. difficile) is Paramount, I opine that the government should continue to enlighten citizens and appeal to them on the need to practice regular hand washing in order to protect themselves and other people. Passing the said law is a draconian approach to the problem hence it is not in line with the ethics of modern civilization.

It is more civil to continue to appeal to citizens and sensitize them on the importance of regular hand washing as it affects the spread of Clostridium Difficile (C. difficile) .
