The seed formed inside the ovary of the flower. As the seed develops in the flower, water is withdrawn from it so that it becomes almost dry. suggest why is it important?
Answers
Water withdrawal from the developing seed inside the flower is important to induce dormancy, enhance longevity, protect against pathogens, facilitate dispersal, and trigger germination under favorable conditions.
Water withdrawal from the seed during its development inside the ovary is crucial for seed dormancy, longevity, protection, dispersal, and germination. Dormancy enables seeds to survive unfavorable conditions. The dry state reduces metabolic activity, enhancing seed longevity. Withdrawing water creates an inhospitable environment for pathogens, safeguarding the seed. Dry seeds are lighter and more easily dispersed by wind, animals, or water, aiding in the colonization of new habitats. Rehydration of the seed after dispersal triggers germination, initiating growth.Overall, water withdrawal from the seed inside the ovary serves as a survival strategy, allowing seeds to endure harsh conditions, remain viable for extended periods, avoid microbial damage, disperse effectively, and germinate when conditions are favorable.

The elephants represented in lanes 3 and 5 could have been a match to the ivory sample if you failed to amplify one allele in either the ivory or the sample, so you cannot exclude these choices without running the experiment multiple times. On the other hand, you can definitely eliminate the elephants in lanes 1, 2, 4, and 6. Explain why.
Answers
About the question:
I failed to find the result of the PCR / electrophoresis. However, I will try to explain when to still consider a sample, and when to exclude it.
Answer:
Probably elephants 1, 2, 4, and 6 exposed a pattern of lines that differed in most alleles from the ivory´s pattern. So they were considered to be different and, hence, excluded. However, elephants 3 and 5 only were different in one allele, which might be due to the amplification failure. In these last situations, the experiment must be run again, and include many markers.
Explanation:
The genetic profile is the series of alleles, characteristic of each individual, concerning a series of DNA fragments.
Once genetic profiles are obtained by using PCR/electrophoresis, they must be subjected to interpretation. The researcher must compare profiles to find concordance between individuals or the lack of it.
In the exposed example, probably we have a profile of the ivory sample, and we need to find out to what individual or population it belongs to. So we need to compare the pattern of bands of the different lanes with the ivory´s pattern of bands.
In resumed terms, if the ivory´s patterns completely match with another lane pattern, then this is the individuals or population to whom it belongs the ivory. However, if they do not match, we need to exclude this individual.
But this is not as easy as it looks like. Sometimes it is difficult to interpret the results because bands are not so clear, and sometimes there are failures during amplification, as said before in the statement of the problem.
In these situations, what you need to do is look for the lanes that match the most with the ivory one and discard those that differ the most. These last patterns probably belong to a different animal or population, that why they can be excluded. Individuals suspected of being the same as the individual understudy or belonging to the same population, must be subducted to a repetition of the study. Also, the use of several markers in the study increases the matches chances.
So, in the exposed example, if the amplification fails in one allele, elephants 3 and 5 could be a match to the ivory sample, probably because all the other alleles do match. You can only exclude them if, after the experiment repetition, the involved allele is still different. On the other hand, you can eliminate the elephants 1, 2, 4, and 6 because their pattern bands are significantly different from the ivory´s patterns, so you do not even need to repeat the experiment.

Answers
Answer: exact, cell division
Explanation:
When replication is complete, two exact copies of the DNA molecule have been produced, and the cell is ready to begin cell division.
The completion of replication produces two exact copies of the DNA molecule and the cell is ready to divide from there onward.
Replication and cell divisionBefore a cell can divide, the genetic materials of the cell must be replicated during the interphase of the cell cycle.
Replication of DNA occurs at the S phase of the cell cycle. Thereafter, the cell commits itself to dividing.
Replication leads to the production of a carbon copy of the cell's DNA. Thus, if a cell has a N amount of DNA before replication, it will have a 2N amount once replication completes.

Answers
The reproductive barrier is a type of prezygotic and postzygotic reproductive isolation after then. Postzygotic isolation occurs after members of two different species have mated and produced a zygote.
Prezygotic barriers to reproduction appear to fall into five primary categories: geographic, Postzygotic temporal, mechanical, gametic, & behavioral barriers. In order to prevent cross-species mating and maintain each species' distinct identity, nature frequently engages in reproduction. This protects the many existing species by dividing them or limiting gene flow. In this setting, hybrid offspring were born, but due to their lower fitness, they have a lower chance of reaching sexual maturity. Postzygotic isolation occurs after members of two different species have mated and produced a zygote. Postzygotic isolation limits the development of fertile progeny while prezygotic isolation stops the fertilization of eggs. Habitat isolation, restricted breeding times, "mechanical" isolation, gamete isolation, and behavioral isolation are examples of prezygotic mechanisms.

A. Incinerate the waste in areas with low populations.
B. Find a way to trap the mercury before it is released.
C. Reduce the number of medical procedures performed.
D. Stored the waste underground instead of burning it.
Answers
To solve the problem of hazardous waste generated from medical procedures and the release of chemicals like mercury into the air, a combination of technological approaches can be employed.
B. Find a way to trap the mercury before it is released: Implementing advanced filtration systems and scrubbers in medical waste incinerators can effectively capture and contain mercury and other harmful substances. This prevents their release into the environment and ensures their proper disposal.
D. Store the waste underground instead of burning it: Rather than incinerating medical waste, an alternative method involves safely storing it underground in specially designed containers. This approach minimizes the risk of releasing hazardous chemicals into the air and reduces the potential for environmental contamination.
A. Incinerate the waste in areas with low populations: Locating medical waste incinerators in remote or sparsely populated areas can help minimize the exposure of nearby communities to hazardous emissions. This approach ensures that the impact on public health is minimized while still addressing the waste management problem.
C. Reduce the number of medical procedures performed: Implementing strategies to reduce unnecessary medical procedures, optimizing healthcare practices, and promoting preventive measures can effectively reduce the overall volume of medical waste generated. This approach not only mitigates the waste management issue but also has broader benefits in terms of healthcare efficiency and cost-effectiveness.
