tatyana61 [14]
What is an invasive species? they are plants/fungi/animals that isn't native to a specific area (an introduced species). They have the tendency to spread and cause damage too the environment, human economy, and/or human health. The Answer to your question is No. Not every species that is introduced to a specific area is invasive. The introduced species might have a natural predator that might eat it. The species may even be biologically, chemically, or mechanically controlled. I hope this helps you out:)

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype? Conduct a
Archy [21]
The answer is <span>Conduct a test cross with a purebred recessive plant. 

</span>

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.

<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.

<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>

A population that is decreasing in size will have an age-structure histogram shaped like a(n): 1) inverted pyramid, with a narro
lawyer [7]

The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.

The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.

In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.
