Based on this video, the definition for an Invasive Species is a ...
species that is not native to an area and was brought by people.
or
species that is not native to an area, has no limiting factors to control its population which then causes harm.
Answer:
Option 2
Explanation:
I did not see the video referenced, but an invasive species is not always brought by people. Furthermore generally there are no limiting factors because it has no natural predators in the environment and often uses up all the resources in that particular environment. Hope this helps!

What is extinction?
Your own word
Answer:
I hope this helps :)
Explanation:
Extiction is where certain species or race no longer exists. Like a sabor tooth tiger, you wont see none of those around, because they are extinct.
Answer:
extinction in my own words is a loss of species, for example the dinosaurs weather some people think there real or not they went extinct many animals are going extinct everyday because of poachers or just a loss of habitat, but extinction is when u think about kind of hard to say because we could say that there is a species of an orange bird that has gone extinct but then out of no where scientist suddenly confirm that there is a whole island of orange birds so in conclusion I think extinction is the sudden loss of a species due to their surrounding and habitats

A. What is exponential growth?
Answer:
A process that increases quantity over time.
Explanation:
The formula for exponential growth of a variable x at the growth rate r, as time t goes on in discrete intervals (that is, at integer times 0, 1, 2, 3, ...), is:
[tex]X_{t}= X_{0} (1+r)^{2}[/tex]
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself.

If a nerve cell stopped functioning, the cell would
a. start producing oxygen.
b. begin dividing into more cells.
c. become a different type of cell.
d. stop sending signals to the brain.
Answer:
D
Explanation:
Only logical and possible solution
If a nerve cell stopped functioning, the cell would stop sending signals to the brain. Thus, the correct option is D.
What are the functions of a nerve cell?The functions of a nerve cell are as follows:
It receives messages from all the different parts of the body. It plays an essential role in the transformation of messages to the brain. Nerve cells are also involved in commanding the different functions of the organs through the brain.So, if nerve cells deal with the electrical impulses and transformation of information and messages from one part of the body to the another, they definitely do not deal with the production of oxygen, division of more cells, and become a different type of cell.
Therefore, stopping sending signals to the brain is an appropriate function of the cell, once a nerve cell stopped functioning. Thus, the correct option for this question is D.

Use the idea of diffuseition to explain how the smell of perfume travel.
Answer:
Diffusion is a process in which a movement of substance takes place from a high concentration area to a low concentration area due to the random movement of the particles.
The smell of perfume travel because the particles move from their high concentration to low concentration and mix with the gases present in the atmosphere. Diffusion happens in gases more faster than liquids and solids because of the random movement of their particles.
Jordan is asked to draw an image of where he might find igneous rocks. Jordan can figure out where this rock would be found by learning how it is formed. Which of the following will mostly likely cause the formation of igneous rock due to tectonic plate movement?

A. they formed along a boundary where two continental plates collide and push the land upwards
B. they formed along a ridge where tectonic activity produces volcanoes would erupt and grow taller
C. they formed where two plates pull apart and produce new crust which increases the elevation of the old crust.
D. they formed where one plate is moving under another plate and sea level drops which makes the mountains taller.

10 Aldovanda vesiculosa and Dionaea muscipula are both species of carnivorous plants. This shared method of getting nutrients is evidence that these two species share a common ancestor. The correct option is D.
What are carnivorous plants?Carnivorous plants, such as the Venus Fly Trap, capture, and eat insects and other arthropods in order to obtain part or all of the nutrients they need.
These plants eat insects to get nutrient because they grow in places where the sun do not reach them.
Shared a common ancestor means that the before species of these plants would be similar and due to mutation or natural selection, the species go far apart, but they still share common characteristics.
Therefore, the correct option is D. Share a common ancestor.

Researchers have been able to study the pathway of a secreted protein by tagging it with a fluorescent marker. Using this method, you would observe Fluorescence moving from the ER to which organelle
Answer:
I would observe fluorescence moving from the ER to the Golgi apparatus.
Explanation:
Once the protein leaves the endoplasmatic reticulum (ER), it is in a vesicle that fuses with the Golgi apparatus. The Golgi modifies and packs the protein to send it to its destination. In other words, the Golgi complex is the place where proteins go to be functional and be given a place either inside or outside the cell.
(ii) Explain why asexual reproduction leads to genetically identical offspring.
Explanation:
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. ... During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.A chromosomal mutation is best described as —
Answer:
Chromosome structure mutations are alterations that affect whole chromosomes and whole genes rather than just individual nucleotides. These mutations result from errors in cell division that cause a section of a chromosome to break off, be duplicated or move onto another chromosome.
