Name a species (common name is fine) of Saurischia (dinosaurs) that isn't extinct

1 answer:

8 0

One example of a common day Saurischia, or more accurately a currently living direct descendent of this group, is the chicken.

As far as the Saurischia go, they represent a large group of dinosaur species. The fact is that long ago, all non-avian members of this group went extinct. The remaining members were avians, a word currently associated with birds. This in part provides an explanation for the fact that most of these remaining Saurischia later evolved into many of the common-day birds we see in the modern world.

Therefore, to give the most popular and clear example of what we can consider as a member of the Saurischia that is still alive today, we can use the common chicken. The chicken is a direct descendent of the dinosaurs and is the animal that genetically is the closest in relation to dinosaurs.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to deter

podryga [215]

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

<h3>What is a recessive phenotype?</h3>

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

p^2 + 2pq + q^2 = 1

where;

p^2 is the h0m0zygous dominant phenotype frequency
2pq is the heterozygous phenotype frequency
q^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Which of the following best explains why deforestation increases the risk of floods in an area?a. Tree leaves catch and retain r

Illusion [34]

Answer: D) Tree roots improve soil water retention

There are many reasons which states that deforestation increases the risk of flood. First , some water stay on the leaves and evaporates in to the atmosphere. Second, tree leaves reduce the impact of raindrops on the soil which causes less soil erosion.

Third, tree roots absorb water from the soil, which make the soil dry and it absorb more water rainwater. The roots of tree hold the soil in place and reduce the movement of sediment which reduce the capacity of river to break its banking. Thus, reducing the chances of flood.
