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

Answers

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. It is used as a source of information to identify threats at the population level for each species on Planet Earth.  

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.  

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

What is five kingdom classification?

The main purpose of the classification of the Five kingdom has been known R.H. Whittaker.  The five kindoms that has were included in this proposal were the Fungi, Protista, Monera.

Animalia as well as the kingdom Plantae. There are mainly five criteria or the conditions based on which the classification has been madeup of. These criteria has been includes the structure of the cell,  as well as the nutrition mode, organisation of the thallus, or the relations of reproduction and phylogenetic.

Based on shoe characteristics they were to develop a classification hierarchy of shoes, beginning with the shoe "kingdom" and becoming more and more specific, just like scientists did for the classification of living things.

Therefore, The transfers seeds away from plant to grow is not a purpose that the flower serves in an angiosperm. Thus, option D is correct.

Answer:

The correct answer is -

Actin produces thin contractile filaments within muscle cells,

Myosin produces the dense contractile filaments within muscle cells

Explanation:

Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.

Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.

Eukaryotic chromosomes contain two general domains that relate to the degree of chromatin condensation. These two regions are _

Answers

Answer:

This question lacks options, options are: A) Heterochromatin and euchromatin

B) Uniform in the genetic information they contain

C) Separated by large sketches of repetitive DNA

D) Each void of typical protein-coding sequences of DNA

E) Void of introns.  

The correct answer is A.

Explanation:

The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.
