1. The genetic material is a good evidence of evolution because it's been conserved through time but with some slight differences.
Another important aspect is the </span><span>mitochondria.</span><span> The mitochondria resulted from a symbiotic relationship
between bacteria and pre-eukaryotes. Explaining why the </span><span>mitochondria looks like a bacteria and has </span><span>bacterial DNA.
2. specialized cellular modifications:
There are cellular modifications happening in multicellular organisms. That means, they have different types of cells, with different functions and will express different characteristics. For example:
- </span><span>Nerve
cells have
dendrites which is important to receive the electrical signal from another neuron, other cells don't have that.
- Sperm cells have a tail ( </span><span><span><span>flagellum) in order to swim through the vagina and no other cell has that.

Answer:
The initial step of producing protein in a pig kidney artificially may involve the study of number mRNA produced by kidney.
Explanation:
As the protein is produced mainly in the kidney by studying the mRNA produced in it. It shows the locations of kidney elevated proteins such as the – proximal tubules, glomeruli etc. The maximum amount of proteins is seen in the genes, present in the kidney.
The whole system of kidney shows that the gene expression is shared mostly with the liver. So while producing the artificial protein in pig kidney, the number of mRNA should be considered.
The type of fault usually occurs because of tension is normal fault. It is a kind of fault that occurs when the Earth's crust is extended. It is a dip-slip normal fault where the hanging wall moves downward and it is relative to the foot wall. Basically, the lithosphere is being stretched.
Answer:
B) Cumulus, Hope this helps :)
The Mesozoic Era began roughly around the time of the end-Permian extinction, which wiped out 96 percent of marine life and 70 percent of all terrestrial species on the planet. Life slowly rebounded, eventually giving way to a flourishing diversity of animals, from massive lizards to monstrous dinosaurs.
The Triassic Period, from 252 million to 200 million years ago, saw the rise of reptiles and the first dinosaurs, the Jurassic Period, from about 200 million to 145 million years ago, ushered in birds and mammals, and the Cretaceous Period, from 145 million to 66 million years ago is known for some of its iconic dinosaurs, such as Triceratops and Pteranodon.
