Answer:
lungs and kidneys
Explanation:
The median plane divides the body into two halves through a mid line.
The transverse plain is also known as the axial plane and it divided the body into the upper part and a lower part.
The frontal plane is also known as the coronal plane. It divided the body into the dorsal and ventral sections. The dorsal and ventral sections are the front and back sections ( belly and back).
Lungs and kidneys are the only parts which cannot be seen through all the three plains.
Answer:
a) Teeth arose from the rough scales of ancestral sharks.
b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
Explanation:
The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.
Answer:
I think Galaxy hope this help in anyway!
Explanation:
Answer:
1) First the DNA strands unwind, and RNA polymerase binds to the template strand.
2) Then synthesis of mRNA begins.
3) Then mRNA undergoes intron splicing and exits the nucleus.
4) Then tRNA moves through mRNA with the activated amino acids
attached to it.
5) Lastly, amino acids assemble
s to form peptide.
Explanation:
Answer:
The modern taxonomic classification system has eight main levels (from most inclusive to most exclusive): Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species Identifier. Every different species has a unique species identifier and the more closely a species is related to it on the evolutionary tree of life, it will be included in a more inclusive group with the species being classified.
