Fossil record- species evolve differently in different environments . different species evolve similarly in the same type of environment
homologous structures of living organisms- 2 variations; similar body structures that don't necessarily have similar functions
homologous- diff mature forms but develop from embryonic tissues
vestigial- similar structures with reduced size and lesser or no functions
embryology- early stages of many animals are very similar- suggesting that organisms share common ancestry
An extracorporeal liver device is similar to a kidney dialysis because this is the device used for liver dialysis.
Liver dialysis or technically known as Single-Pass Albumin Dialysis is designed to remove protein-bound toxins. It is the simplest form of albumin dialysis which utilizes the rudimentary principles of hemodialysis or hemodiafiltration. The dynamics of this procedure begins with the patient's blood flowing through a standard high-flux dialyzer that is impermeable to albumin. This is then dialyzed against a dialysate with an albumin concentration of 2%-5%, which is discarded after a single pass. It allows the removal of albumin-bound molecules that are minute enough to pass through the porous membrane and as well as water-soluble toxins.
Answer:
Alleles
Explanation:
In diploid organism, genes occur in pairs on chromosomes and such pairs are referred to as allelic pairs. An allele is an alternative form of the same gene that controls the development of a pair of contrasting genes. The genetic constitution of an organism is known as genotype while its phenotype refers to a set of observable characteristics of an organism which are an expression of an individual genotype.
Answer:
Explanation:
A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.
Answer:
A - DNA
B - mRNA
C - nuclear pore
D - tRNA
E - ribosome
F - rRNA
Explanation:
<em>The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.</em>
The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
