Two,
one.
Ddee plants can make the following types of gametes;
parent can make half dominant D type gametes and other half recessive d gametes. Since both e gametes are recessive, the gametes formed will be 100% e gametes.
therefore the combinations of gametes possible are De and de.
In ddee plants, both d and e are recessive therefore parents can make only gametes with recessive d and e alleles.
therefore gametes produced are of a single type, that is de only.
The answer is <span>B. fibrin.
Through the process of elimination: thrombin and thromboplastin are enzymes so these choices are incorrect. Platelets are actually cells, which leaves us B. fibrin as the correct choice.
</span>A fibrinogen is a protein involved in the formation of blood clot. It is converted by enzyme thrombin into fibrin during blood clot formation.
Answer:
B
Explanation:
The equator receives more of sunlight throughout the year, compared to increasing latitude, hence the atmosphere and oceans within this latitude are warmer. When winds blow away from the equator, they transfer this heat energy to the cooler higher latitudes.
Answer:
the strengths are force and limitations are lamp
If the cell under the microscope appears to be in fourth grade it indicates that it is ready for cell divison or mitosis .
Explanation:
* if the cell reaches the fourth stage , it increases in size .
* At about the same time , the copying of the DNA happens
this is the stage where the growth of the cell stops completely .all the concentration would be towards the division of the cell.This is the stage where the cell divides into two daughter cells .after this division , the two daughter cells also ,begin their cell cycles. so ,fourth phase of cell cycle is the beginning of the cell cycles of many daughter cells also .
