Answer:
b energy level of outer electrons
Explanation:
This is because their atoms have the same number of electron in the highest occupied energy level.
Water helps keep cells in an even temperature despite temperature changes in the environment because water has a high heat capacity. Water can absorb a lot of heat before there’s a change in the temperature.
I hope this helped!
True statements are
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom.
In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation:
Diploblastic animals (radially symmetric animals like jelly fish, sea anemone) has only two layers – the endoderm and the ectoderm. It does not have mesoderm germ layer. Diploblastic animals are formed from the embryonic process called gastrulation from a blastula cells.
A true coelom and pseudocoelom may differ in their structure or location but their main function is the same. Since both are fluid-filled cavities, they act as hydrostatic skeleton disseminating extra pressure via the body to protect the internal organs and minimize damage.
Each germ layer gives rise to tissues pertaining to a particular organ or organ system. Like the mesoderm provides for muscles, nervous system and the endoderm gives rise to gastrointestinal organs, lungs etc. So the tissues lining outside and inside the body cavity will arise from the same germ layer.
Answer:
C. More than 5 fingers/toes on each hand/foot
Explanation:
According to the given information, polydactyly is an autosomal dominant trait which means that the phenotype would be expressed in both homozygous dominant and heterozygous dominant genotype.
The given genotype is heterozygous dominant. The individuals with heterozygous dominant genotype would exhibit the polydactyly and would have more than 5 fingers and toes on each hand and foot.
Meiosis is the process that accounts for diversity.
