What is a worm-like cell structure derived from chromatin during cell reproduction?
A worm-like cell structure derived from chromatin during cell reproduction is a chromosome. Chromosomes are made up of condensed chromatin that contains DNA and proteins. They are visible under a microscope and play a crucial role in ensuring genetic information is accurately replicated and passed on to daughter cells during cell division.
What structures is derived from the ectoderm?
brain and spinal cord
What was the probable order of occurrence of these derived traits?
Multicellularity, segmented body, hair, placental reproduction
What are the structures formed from the foregut?
Structures which are derived from the foregut are:stomachlivergall bladderpancreasduodenal cap, descending duodenum (1st and 2nd parts of the duodenum)
What are the structures formed from the hindgut?
Structures derived from the hindgut are:distal third of the transverse colondescending colonsigmoid colonrectumupper portion of the anal canal
Did derived structures appear earlier in the phylogeny of an organism than conservative structures?
Read page 12 of the lab manual... Derived is more resent than conservative, therefore it would have appeared later than conservative.
Why does sexual reproduction result in more genetics variation in a species than asexual reproduction?
Asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). Sexual reproduction produces a random mixture of the genetics derived from both parents.In sexual reproduction, offspring are not identical to either parent.
What are the structures formed from the midgut?
Structures which are derived from the midgut are:horizontal and ascending duodenum (3rd and 4th parts)jejunumiliumcecumascending colonfirst two-thirds of the transverse colon
What adult structures is not derived from the same primary germ layer as the others?
The notochord is an adult structure that is not derived from the same primary germ layer as the others. While structures like muscles, bones, and connective tissues derive from mesoderm, the notochord originates from the mesoderm but later forms from the embryonic ectoderm.
Where are the micromeres derived?
Micromeres are derived from early blastomeres during cell division in the embryo. They are the smallest cells produced during cleavage and play a crucial role in the formation of different cell types and structures in the developing organism.
Does sexual reproduction result in more genetic variation in a species than asexual reproduction?
Asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). Sexual reproduction produces a random mixture of the genetics derived from both parents.In sexual reproduction, offspring are not identical to either parent.
Anatomical structures that appear to be derived from a functional structure in an ancestor but that currently do not serve an important function are called?
Vestigial structures. These are remnants of organs or body parts that have lost their original function through evolution. Examples include the human appendix and wisdom teeth.
