In the late 1960s, Robert Paine conducted landmark studies on diversity in the rocky intertidal zone, comparing the species dive

rsity in control plots with diversity in experimental plots from which he removed the top predator, sea stars. After 5 years, 15 species of intertidal invertebrates lived in the control plots, while the experimental plots were dominated by only two species, one mussel and one barnacle. The process MOST likely responsible for the loss of species diversity in the experimental plots was:A. mutualism.B. predation.C. competitive exclusion.D. parasitism.E. resource partitioning.

Answer:

C: competitive exclusion

Explanation:

<em>The competitive exclusion principle states that organisms living in the same community while competing for the same resources cannot coexist at a constant population rate. </em>

Once some of the species within the community get a slight competitive edge over other species, they become dominant and this might lead to the extinction of the weaker species in the long run.

<u>In the experimental plot, the removal of sea stars provided mussel and barnacle with a competitive advantage over other species within the community (sea stars are predators of mussels and barnacles). This led to the dominance of mussel and barnacle and the eventual extinction of other species within the experimental plot as compared to the control plot.</u>

The correct answer is C.

Mendel's law of independent assortment states that which allele is passed down to the next generation at one locus is dependent
dlinn [17]

Answer:

False

Explanation:

Mendel's law of independent assortment is about the random distribution of alleles of one gene during anaphase-I. It states that alleles of two or more genes segregate randomly to the poles of the cell. For example, the segregation of R and r alleles to the two poles of the cell would not affect the segregation of the T and t alleles. This random and independent segregation of alleles of different genes during anaphase-I produces new gene combinations in the progeny.

Malaria was once prevalent in Europe and the USA in the early 1900s but was successful eliminated from these areas. However, mal
Leokris [45]

Answer:

Yes it is correct to say.

Explanation:

The disease in the question, malaria, is an infectious disease what is mosquito borne and its symptoms start from fever, headaches and goes up until death.

There is no direct correlation between poverty and the disease but there is an indirect one. Since these poor countries in Asia, Africa and South America are dealing with poverty, this causes the invertentions for the spreading of the disease, the general knowledge of the public, the healthcare and the treatment of the disease to be low and therefore malaria is still provalent in these parts of the world.

I hope this answer helps.

Mitochondrial dna (mtdna) recovered from a fossil hominin from sima de los huesos in northern spain shows connections to the mtd
Fofino [41]

Mitochondrial DNA (mtdna) recovered from a fossil hominin from sima de los huesos in northern spain shows connections to the mtdna of the Denisovans.

The Sima de los Huesos showed distinctive proof of DNA survival over an extended period of time. Based on the enzymatic amplification of a few short mitochondrial DNA (mtDNA) fragments from Middle Pleistocene cave bear bones. Given that the Sima de los Huesos fossils have Neanderthal-derived characteristics (such as in their dental, mandibular, midfacial, supraorbital, and occipital morphology), it is unexpected that the mtDNA from these fossils has a common origin with Denisovan rather than Neanderthal mtDNAs.
