A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.
Minchanka [31]

Answer: Living Planet Index

Explanation:

The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. <u>It is used as a source of information to identify threats at the population level for each species on Planet Earth</u>.  

With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.  

<u>The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.</u>

Which one of the following statements about RNA processing is correct? (A) Exons are cut out before mRNA leaves the nucleus. (B)
Ghella [55]

The correct statement is that the ribozymes may function in RNA splicing.

Non-proteinaceous RNA enzymes are known as ribozymes. They function as molecules that catalyze reactions in which RNA is the catalyst. Within the nucleic acid molecules, these molecules have the capacity to both break and create covalent bonds. RNA splicing may be facilitated by ribozymes. Despite having a small chemical repertoire, they have a wide range of biological functions and are essential for the three kingdoms of life. They are involved in the maturation of transfer RNA, intron splicing, the replication of RNA viruses or viroids, the control of messenger RNA stability, and protein synthesis.

Why is measuring the rate of oxygen production in chloroplasts appropriate for estimating the rate of photosynthesis?
Shalnov [3]
Hello! During the process of photosynthesis, oxygen is released as a waste product. Therefore, measuring the rate of oxygen production can estimate the rate of photosynthesis. Hope this helps! :)
