composition on photosynthesis​

Answers

Answer:

The effects on pigment composition and photosynthesis of low temperature during growth were examined in the third leaf of three chilling-tolerant and three chilling-sensitive genotypes of Zea mays L. The plants were grown under a controlled environment at 24 or 14 °C at a photon flux density (PFD) of 200 or 600 μmol m–2 s–1. At 24 °C, the two classes of genotypes showed little differences in their photosynthetic activity and their composition of pigments. At 14 °C, photosynthetic activity was considerably reduced but the chilling-tolerant genotypes displayed higher photosynthetic rates than the chilling-sensitive ones. Plants grown at 14 °C showed a reduced chlorophyll (Chl) a + b content and a reduced Chl a/b ratio but an increased ratio of total carotenoids to Chl a + b. These changes in pigment composition in plants grown at low temperature were generally more pronounced in the chilling-sensitive genotypes than in the tolerant ones, particularly at high PFD. Furthermore, at 14 °C, all the genotypes showed increased ratios of lutein, neoxanthin and xanthophyll-cycle carotenoids to Chl a + b but a reduced ratio of β-carotene to Chl a + b, especially at high PFD. At 14 °C, the chilling-tolerant genotypes, when compared with the sensitive ones, were characterized by higher contents of β-carotene and neoxanthin, a lower content of xanthophyll-cycle carotenoids, a lower ratio of xanthophylls to β-carotene, and less of their xanthophyll-cycle carotenoid pool in the form of zeaxanthin. These differences between the two classes of genotypes were more pronounced at high PFD than at low PFD. The results are discussed in terms of the relationship that may exist in maize between pigment composition and the capacity to form an efficient photosynthetic apparatus at low growth temperature.

The most serious environmental effect of rising sea levels isThe most serious environmental effect of rising sea levels is

Answers

The most serious environmental effect of rising sea levels is increased coastal flooding and erosion, threatening habitats and infrastructure.

The most serious environmental effect of rising sea levels is the inundation of coastal areas, which poses a significant threat to ecosystems, habitats, and human populations.

As sea levels rise, low-lying coastal regions become more susceptible to flooding, resulting in the loss of land, erosion of beaches, and destruction of coastal wetlands.

These changes disrupt delicate coastal ecosystems, including mangroves, salt marshes, and coral reefs, which serve as vital habitats for numerous species and provide natural protection against storms.

Additionally, rising sea levels contribute to saltwater intrusion, contaminating freshwater sources and impacting agriculture and drinking water supplies.

The displacement of coastal communities and the loss of infrastructure, including homes, businesses, and critical facilities, further exacerbate the social and economic impacts of rising sea levels.

The environmental consequences are profound, requiring urgent adaptation and mitigation efforts to protect vulnerable coastal areas and preserve biodiversity.

D. Allow the Constitution to be updated to suit changing times

Answers

Answer:

D

Explanation:

It doesn't prevent small political groups from blocking changes to the Constitution because the amendment was approved by a higher percentage of states than the House and Senate.

It doesn't make the process of changing the Constitution as easy as possible because it still needs to go through many stages of approval.

It doesn't ensure that state governments submit to federal authority under the Constitution because, again, the state had a higher percentage in vote.

So, D must be the correct answer; with the collective view of the states, house and senate, the amendment can reflect the needs of the time.
