Answer:
The correct answer is D
Explanation:
That's why in the graph the best reaction of the enzyme is on 40° C.
On low temperatures the enzyme activity is too low.
On very high temperatures it fall, so the enzyme works better in the middle temperatures.
Answer: Possession of traits that aid their survival in extreme conditions.
Explanation: Because archaea that grow in extreme environments possess certain characteristics that aid in their survival in the extreme weather conditions. Those traits are studied regularly to improve other plants.
One way that cancer can form is when abnormal cells have uncontrolled growth, old cells die and get added on to which I believe creates tumors.
Image 1.1 -
Stomata are little moth-like structures in leaves, that, when open, allow the exchange of gases between the plant and the exterior.
Answer:
B.
Image 1.2 -
Without the existance of stomata, the process of transpiration wouldn't be possible if there weren't structures thata allowed the exchange of gases.
Answer:
A.
Image 2 -
So, we can elminate plants because they can photosynthesise; bacteria because they are prokaryotes and can photosynthesise; archaea because they are prokaryotes; hat leaves us with animals and fungi because these cannot photosynthesise and are both eukaryotes.
But, we cannot skip information. It is also said that the organism found has a cell wall, and animals do not have cell walls.
Answer:
C.
Image 4 -
Option 1 = cilia
Option 2 = flagella
Option 3 = pseudopods
Option 4 = pili (they're a meant to attacht to surfaces only bacteria)
Image 5 -
Runner stems are those that grow horizontally, therefore the fourth image with the long horizontal stems.
Rhizome stems are underground stems that can form roots or shoots through their nodes. Therefore, the third image with white background (the one with 2 drawn plants).
Tuber stems are large underground (mostly) structures used as storages for the plant. Therefore, this corresponds to the first image (the one with the white background.
Bulb stems are short and "bulby" stems, whith thick, leaves. Therefore, the second image (the one with the grass background).

Interphase: Add mushrooms to represent organelles and a ring of pepperoni to make a nuclear membrane. Strips of peppers would represent the DNA inside the nucleus. To model the end of interphase, double the number of mushrooms on the pizza to indicate the copying of the organelles. Double the number of peppers inside the nucleus to represent the replication of DNA.
Prophase: Pair strips of pepper inside the nucleus to show the formation of chromosome pairs. Strips of aluminum foil would represent spindle fibers.
Metaphase: Line up the pair of peppers along the middle of the pizza. Removing the pepperoni would show the breakdown of the nuclear membrane.
Anaphase: Split up the pairs of peppers, and show the spindle fibers, made of aluminum foil, pulling them to either side of the cell.
Telophase: Make two new nuclear membranes around the pepper strips using pepperoni. Separate the pairs of peppers to show the chromosomes unwinding.
Cytokinesis: Cut the pizza across the middle to show the cell dividing into two daughter cells.
