Answer:
In a frog embryo, gastrulation E) proceeds by involution as cells roll over the dorsal lip of the blastopore.
Explanation:
Gastrulation is key because during it, cell movements result in a massive reorganization of the embryo from a simple spherical ball of cells, the blastula, into a multi-layered organism. Also many of the cells at or near the surface of the embryo move to a new, more interior location. <em>It involves changes in cell motility, cell shape, and cell adhesion.</em>
Answer:
There will be fewer rabbits with large ears than any of the others.
Explanation:
The given problem states that initially the number of rabbits are equal, whether rabbits with large ears or rabbits with small and medium sized ears.
In winters more of the large-eared rabbits die and in summer short-eared rabbits die as compared to other rabbits.
Thus, the given problem makes clear that medium sized ones do not die so frequently. So, the rabbits that will reduce in amount will be either large sized or small sized. After several years, small sized ears will definitely grow.So, the ones that will reduce in amount the most will be the rabbits with large-size ears. Hence, large-sized ear rabbits will be fewer in number.
