Simpson's Diversity Index is a measure of diversity which takes into account the number of species present, but does not include

the relative abundance of each species. True False

Answer:

The given statement is false.

Explanation:

In ecology, one of the means of measuring diversity is Simpson's Diversity Index. This index is generally used to count the biodiversity of a habitat. The index considers the number of the present species, and at the same time each species' abundance.

Simpson's index denoted by D determines the possibility that two characters selected abruptly from a sample will fit to a similar species or some classification other than species. When the value of D is 0, it signifies infinite diversity, while when the value is 1 it denotes no diversity. Thus, the bigger the value the lower will be the diversity.

Historically, the earth’s ocean had a ph of 8.2. In recent years it dropped to 8.1. How might this affect the ocean environment
Mrac [35]
Well with the ph above 7 that means the water is more of a base due to the salt within the water.  the decrease in the ph is due to gloabal warming and the melting of ice which is somewhat diluting the water more.  the wildlife within the ocean has been there since you or i so some creatures have developed a very specific habbitat and less salt withing the water could have effects on them.  one such instace is if the organism needs a lot of salt.  a decrease in salt would mean that their cells would bloat with water until they explode. this would obviously hurt the species as a whole and in turn effect the whole food chain.

What characteristic do protozoa and fungi share?
Nadusha1986 [10]

Answer:

<h2>letter A</h2>

Explanation:Whittaker placed bacteria in their own kingdom, Monera, because of fundamental organizational differences between prokaryotic bacterial cells, which lack membrane-enclosed nuclei and organelles , and the eukaryotic cells of other organisms that possess internal membranes. Plantae, Fungi, and Animalia consist of complex, multicellular eukaryotic organisms that differ from each other in details of cell structure and in how they secure and process energy. Protista is a collection of single-celled eukaryotic organisms and simple multicellular forms, some animal-like, some plantlike.

<h2>letter b</h2>

Molecular evidence, particularly from ribosomal ribonucleic acid (RNA), suggests that the five-kingdom scheme is also too simple. Some biologists believe that Protista should be partitioned into three or more kingdoms. Similarly, kingdom Monera contains two very biochemically distinct groups of prokaryotes: archaebacteria, and eubacteria. A proposed system acknowledges this ancient evolutionary split by creating a higher level of classification, domain, above kingdom. This system distinguishes three domains: Archaea, Eubacteria, and Eukarya (containing protists, plants, fungi, and animals).

What second messenger most directly causes calcium ions to be released from intracellular stores?
NemiM [27]

Answer: adenylyl cyclase inositol triphosphate mainly known as IP3 causes the release of Calcium ions directly from the inracellular stores and causea contraction.

Explanation:

IP3, inositol phosphate is a second messenger a signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, by an enzyme phospholipase C.

IP3 binds to the calcium channels and opens Ca2+ channels that are embedded in the ER membrane, releasing Ca2+ into the cytosol. Calcium ions released may cause contraction and regulate the Ca2+ channels in the membranes.
