Answer:
. Reproduction is aided by flowers, protected seeds, and insect pollinators.
Explanation:
The set of plants which produces flowers that develop to fruits,which houses seeds are called angiosperms.They are the most diverse plants species . The fruits are edible,while the flowers are reproduction.The seeds are for regeneration.
They are vascular plants with specialized tissues of xylem and phloem,and other tissues for structural characteristics.
Insects,animals,man and wind are the agents of pollination of the flowers, The Pollen grains from these flowers are transferred far away from the original parent sources,Hence this ensure widespread dispersal,and diversity of Angiosperm population.
Answer: A
Explanation: It makes the most sense because it isn't directly speaking about something, it is mainly summarizing the main idea. I'm not 100%, but that's the one I would choose if it were me. Hope I helped out a little!
Answer:The cell cycle a. includes mitosis as an event.
Explanation:
The cell cycle consists of two stages:
interface and phase M (mitosis). In the first, the cell grows and doubles its DNA; It consists of phases G1, G2 and S. In phase M, the cell divides its already duplicated DNA and the cytoplasm divides into 2 (cytokinesis), forming 2 daughter cells. There is a G ° phase, where the cell is in a "vegetative" state, called "senescence." The cell cycle is regulated cyclin / CDK complexes, tumor suppressor genes (example: p53).
<span>Here square frequency of recessive alleles r^2 = 160/1000 = 0.16
Therefore r = 0.16
Since r + d = 1; d = 1-0.16 = 0.84</span>
Answer:
Like a sperm cell, the egg contains a nucleus with half the number of chromosomes as other body cells. Unlike a sperm cell, the egg contains a lot of cytoplasm, the contents of the cell, which is why it is so big. The egg also does not have a tail.
