The correct answer is (A) They did not co-evolve with the natural species and lack natural controls, like predators.

An invasive species is a species that not belongs to that land where they are living and was introduced to that ecosystem naturally or deliberately to cause harm to that system as Invasive species have tendency to spread to a degree believed to cause damage to the environment, human economy or human health.

Example of Invasive species include European rabbits, Grey squirrels, domestic cats.

In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive (y). A plant with genotype Yy and a plant with Y

agasfer [191]

<span>Based on a simple Punnett square, you could predict that one of the offspring (with the genotype yy) would present with red leaves. The other three offspring would present the phenotype of the yellow leaves, because the dominant gene (Y) is present (genetypes Yy, yY, and YY).</span>

Which of the following correctly lists the levels of compaction in eukaryotes from naked DNA to the most compact?

nekit [7.7K]

Answer:

The level of compaction in Eukaryotes from naked DNA to the most compact is:

d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome

Explanation:

As we know that the

Diameter of DNA is 2 nm.
Diameter of nucleosome is 11 nm.
Diameter of solenoid is 30 nm.
Diameter of looped chromation is 300 nm
Diameter of meta-phase chromosome is 1400 nm

All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.

Some members of david's family have an autosomal recessive disease. david does not have the disease; neither do his parents, nor

Sauron [17]

A pedigree shows the genotypes of the family members
in autosomal recessive disorders, the diseased genes are inherited from the parents. For the person to get the disease both diseased genes should be there in the genotype as its a recessive disorder.
the dominant gene - H
recessive gene - h
for a person to get a disease, genotype should be hh, as its autosomal recessive. If the person is normal he/ she could have the genotype HH or could be Hh and thats called a carrier.
the offspring will receive one gene from the mother and one from the father
