Answer:

Image result for explainplination how cephalisation and symmetry, as it relates to the crab is appropriate to the mode of life​

Cephalization is defined as the evolutionary trend toward nervous system centralization and the development of a head and brain. Cephalized organisms display bilateral symmetry. Sense organs or tissues are concentrated on or near the head, which is at the front of the animal as it moves forward.

Each red blood cell is shaped as a biconcave disk. This allows it to?
kipiarov [429]

Red blood cell is shaped as a biconcave discs, this shape allows them to squeeze through small capillaries.

The biconcave shape of the cell allows oxygen exchange at a constant rate over the largest possible area. The biconcave shape increases the cell's surface area compared to a flat disk of the same size. The greater surface area makes it easier for gases to move into and out of the red blood cell.

The biconcave shape provides a large surface area compared to the volume of the red blood cell, allowing diffusion to happen efficiently. This shape optimizes the ratio of surface area to volume, facilitating gas exchange. It also enables them to fold up as they move through narrow blood vessels.

A boy received one dominant allele for brown hair from his father and a recessive allele for blonde hair from his mother. ​Which
Damm [24]

Well say the father had the genotype BB (dominant brown) and his mom had the genotype bb (recessive blonde).

If the boy got only one allele of brown hair and his phenotype is brown hair, then his genetic type is Bb

He is heterozygous (has two different alleles). But since brown hair is dominant, his phenotype is brown hair. But he does have the blonde recessive allele.

Hope this helps!

Describe the processes of transcription and translation in your own words, based on what you have observed in the Gizmo.
Flura [38]

Answer:

Please find the explanation of transcription and translation below using the key words.

Explanation:

Transcription is the process whereby a gene in a DNA template is used to synthesize a messenger RNA (mRNA) molecule in the nucleus of the cell. This process of transcription occurs with the aid of an enzyme called RNA POLYMERASE, which adds the nucleotides complementary to the one it reads in the gene to the growing mRNA strand.

Translation, on the other hand, is the second process of gene expression involving the synthesis of proteins from the mRNA sequence. This process occurs in the RIBOSOME where a group of three nucleotides in the mRNA called CODON is read by another group of complementary nucleotide in the transfer RNA (tRNA) called ANTICODON. The tRNA then carries amino acids corresponding to what is read in the codon to the growing polypeptide chain.
