trust me i’m right lol
Answer:
ASEXUAL
female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally.
SEXUAL
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.
Explanation:
Spore production is the answer
C. Xylem moves water up, and phloem moves food down
Answer:
The correct answer is D. production of new cell-surface proteins with a different molecular structure by each new generation
Explanation:
Trypanosomes infections is famous for evading the immune response of the body because it has the ability to make change in its variant surface glycoprotein having different molecular weight and this phenomenon is called antigenic variation.
So adaptive immune system is not able to recognize the trypanosome by its glycoprotein because the old surface glycoprotein against which the memory cells were produced previous time is now changed.
Therefore the immune system will not recognize the new generation of trypanosome with different variants of cell surface glycoprotein. Therefore the right answer is D.
