Answer:
true
Explanation:
erwin chargaff discovered that the dna of any species contains equal amounts of adenine and thymine, and also equal amounts of cytosine and guanine
based on this information, scientists could predict that the base
pairs with
and the base
pairs with
in the information of the adn molecule
Answer:
The base adenine pairs with thymine, and the base cytosine pairs with guanine.
Explanation:
From Chargaff's discovery, which was that the DNA of any given species contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine, we can deduce that if there is an equal amount of two bases in DNA, those two bases must pair together. From this information, we can then go on to say that since there are equal amounts of adenine and thymine, they pair together, and since there are equal amounts of cytosine and guanine, they also pair together.

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.

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

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!
Why does ice cream placed in a plastic cooler melt slower than ice cream placed in a metal pot?

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.

By looking at a plant, how can you tell if it is a cycad and not a palm?
A. look for pollen
B. look for leaves
C. look for roots
D. look for cones
Answer: Look for the cones
Explanation: I took the test and I got it correct.
Cycads are non flowering plants and palms are flowering plants . Therefore, option (D) look for cones.
What are palms and cycads ?Gymnosperms known as cycads are characterised by their massive, pinnately complex leaf crowns and their cones, which are usually carried at the end of the trunk in the middle of whorled branches. Others have partially submerged stems with inflated (tuberous) trunks and tall, unbranched trunks that resemble armor.
There are three different types of palm tree leaves, known as fronds: fans, feathers, and whole leaves. Typically green, palm tree fronds can have a range of textures, such as waxy, smooth, matte, etc.
In gymnosperms, a leafy green sporophyte produces cones with male and female gametophytes. Female cones are larger and higher up the tree. Male gametophytes (pollen) are produced in male cone microsporophylls and carried by wind to female gametophytes.
Therefore, option (D) is correct about palms and cycad.
