Answer:
the amount of fossil fuels that are available will eventually decline
Answer:
Invasion of the large snakes will cause disruptions in this tropical community by increasing competition in tropic level organisms for their food that is primary and secondary consumers.
Explanation:
Invasive species generally and most often harm the native community and may lead to the extinction of native plants and animals from the community. These invasive species increase competition that results in limiting resources and decreasing diversity.
Large snakes will compete with the higher tropic level organism that depends on the primary and secondary level organism that lead to a decrease or extinction of these organisms. This food web will be completely reduced and disrupted, vegetation will increase.
Answer:
A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization.
Explanation:
Animals with deuterostome development, bilateral symmetry as larvae, and five-part radial symmetry as adults are called Echinoderms.
An echinoderm is any member of the phylum Echinodermata. The adults are recognizable by way of their (generally five-factor) radial symmetry, and encompass starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, in addition to the ocean lilies or "stone lilies".
Person echinoderms are found on the sea mattress at every ocean depth, from the intertidal quarter to the abyssal zone. The phylum incorporates about 7,000 dwelling species, making it the second-biggest grouping of deuterostomes, after the chordates. Echinoderms are the biggest completely marine phylum. The primary definitive echinoderms seemed close to the beginning of the Cambrian.
The echinoderms are critical both ecologically and geologically. Ecologically, there are few other groupings so plentiful inside the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are capable of reproducing asexually and regenerating tissue, organs, and limbs; in a few cases, they are able to undergo entire regeneration from a single limb.

In case of the genes that assort independently in a test cross, the phenotypic ratio is 1: 1: 1: 1. In the given case, the total number of phenotypes is 400, thus, every phenotype should be 100 each. Since that is not the case, it may be concluded that the genes are not assorting independently.
Thus, to determine the chi-square = (observed-expected)^2 / expected.
By putting the values, we get the values of chi-square as
AB = 4.84
Ab = 3.24
aB = 3.61
ab = 4.41
Thus, the chi-square value will be the addition of the individual values that comes out to be 16.1. Here there are three degrees of freedom (Number of classes-1). Observing at the P table, this puts the value of P < 0.005.
A large chi-square value suggests that independent assortment actually did not occur as the expected and the observed values were very distinct.
