In an experiment performed on a starfish four-celled embryo, each blastomere is separated and kept in a culture medium. what could be the possible results of this experiment, provided all the environmental conditions are favorable?

The probable result of this experiment is that each cell originates a complete embryo.

Explanation:

In the question above, the embryo of a starfish was divided keeping each blastomer separate and kept in culture medium.

As you may already know, a blastomer is the structure that sucks when a fertilized egg is divided, in addition, you should also know that starfish have an incredible capacity for regeneration.

For this reason, we can conclude that in the above experiment, as the cells kept in culture media are already fertilized and as the starfish can regenerate itself from each piece, each cell will give rise to a complete embryo, which will originate another starfish.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
