How do you propagate trees​

Biology
1 answer:
miv72 [106K]2 years ago
5 0

Answer:

The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.

Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.

A cell with 2cm side has what surface area?
BlackZzzverrR [31]


since a cell has 6 sides :

       L= length, W= width

surface area = ( L x W ) X 6

                     = (2 X2 )  X 6

                     = 4 X 6

                     = 24 cm²

grin007 [14]

Answer: Option B) allosteric activation

Energy required by the cell is generated in the form of ATP. ATP is hydrolyzed to power many of the cellular processes, increasing the pool of ADP. As the relative amount of ADP molecules increases, they can bind to glycolytic enzymes, which will lead to the production of more ATP. The best way to describe this mechanism of regulation is allosteric activation

Explanation:

Some enzymes have more than one active site. The other site(s) is called allosteric site.

In this case, ADP released from the glycolytic reactions binds to the allosteric sites of glycolytic enzymes, activating them and causing further breakdown of glucose, hence ATP continues to be generated.

ATP + H2O ---> ADP + Pi + free energy

With more carbon in the atmosphere, what do you think will happen to the environment
Vladimir [108]

Answer:

Global warming

Extra carbon dioxide in the atmosphere will increases the greenhouse effect. More thermal energy is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. That increases the Earth's temperature which is also called Global Warming
