For a reaction to occur, substrate particles need to collide with each other with enough force (To overcome activation energy), at the right orientation for a successful collision, causing a reaction to occur.
Enzyme catalysts are a type of protein that has a specific 3 dimensional conformation. They have specific reaction sites called active sites. Substrates collides with the enzyme and binds to the active site if it fits to the specific 3 dimensional conformation. This allows bonds to be either formed or broken for reactions to occur.
This process provides an alternative reaction pathway with lower activation energy to enable the rate of reaction to increase.
Some adaptations you would expect to see on plants growing in both biomes are Low-growing plants, Waxy leaves to protect against evaporation, Ability to grow in soils with very low nutrients and water, and The ability to quickly bloom and reproduce when conditions are right. Hope this helped!
Answer:
The genetic material's inheritability shows how that the DNA of all creatures, both living and dead, can be traced back to a single point, which is our common ancestral origin of life.
Explanation:
Answer:
C - Contains the embryonic disk
Explanation:
After an egg is fertilized, it begins to divide into smaller cells, from the 1 cell stage, to 2, to 4 and so on. Then, on the third day, the cells fall within 16-200 cells and it is then called a <em>morula</em>.
On the fifth day, the morula becomes a ball of calls which is now differentiated into an <em>inner cell mass and a trophectoderm</em>. The inner cell mass becomes the <em>embryo</em> as development goes on and the trophectoderm, becomes the <em>placenta</em>.
As development goes on further, the floor of the amniotic cavity is formed by the embryonic disk, a layer of prismatic cells derived from the inner cell mass.
The embryonic disc develops into 3 layers:
There is a major differentiation of cells which gives a template for the origin of development of specific organs of the embryo.
We are given:
2 units of packed red blood cells infused over 1 hour each, so 1 unit per hour
1 unit is equivalent to 250 ml
10 gtt/mL
solve for the volume per unit time:
1 unit per hour / 1 unit /250 mL = 250 mL per hour
The flow rate in drops per minute is determined by:
- converting hours to minutes:
250 mL per hour * (1 hour / 60 minutes) =4.2 mL per minute
-multiplying gtt/ml to flow rate
4.2 mL/min * 10 gtt/mL = 42 gtt/minute
Therefore the final flow rate in drops per minute is 42 gtt per minute.<span />
