Answer:

An invasive species is an introduced organism that becomes overpopulated and negatively alters its new environment. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.

To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally

A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem

An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

How has increased global travel boosted the spread of certain species?

ser-zykov [4K]

<h3>Global travel and spread of certain species</h3>

Explanation:

Many pathogenic species of bacteria, virus, and other microbes are more prevalent in developing or tropical countries rather than in developed countries.

When an individual’s immune system is weak they become more susceptible to get infected and become carriers of that particular species.

The species grows, develops, and multiplies in the host’s body and when the traveler travels to his/her home country or any other place he/she can transmit the disease to others and again the species grows in numbers. Higher the rate of spread of infection higher is the increase in species.

When mendel crossed peas with rr and rr genotypes (where r is dominant and produces wrinkled peas and r is recessive and results

LuckyWell [14K]

I think your question all turn into lowercases, uppercases, and lowercases are important in genetics because it can differentiate between the dominant and recessive forms.
let me explain at least how to calculate the offspring percentage:
for example, you have Rr crossed with another Rr (R for wrinkled peas and r for smooth peas), you just have to match between the four letters, and you will have four possibilities:
R and R
R and r
r and R
r and r
you will have RR, Rr, Rr, and rr
if we convert into percentages, it will give:
25% RR
50% Rr (there's two Rr so 25 + 25)
25% rr

Marat540 [252]

"A gas is cooling to its boiling point and becomes a liquid" is the answer.

Condensation is the process where a gas becomes a liquid, like after a hot shower, there is fog on your mirror that slowly turns into water droplets after you've turned off the water.
