Answer: Notochord,Nerve cord, pharyngeal gills

Explanation:

1.Presence of notochord that gives them skeletal support this also develops into between Column in vetertebrates.

2.presence of dorsal hollow nerve cord that develops into the brain and spinal cord which is the nervous system. develops into the central nervous system

3.presence of pharyngeal slit that develops into gills in some aquatic organism and its develops into jaw in some mammals. The gills is use for removal of water that enters the mouth while feeding.

How would a small, uncharged lipid move across the cell membrane?
ElenaW [278]

Answer:

Through simple diffusion, down the concentration gradient.

Explanation:

The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here

How do schemas help structure our memories?
Ilia_Sergeevich [38]
Schemas refers to a cognitive frame work which help humans to organize and give interpretations to information obtained both from within and from the external enviroment. Schema guide human cognitive processes and behaviour. Schema helps in structuring our memories by acting as a glue which hold all the information we have gathered together. Shcema is used in recognizing new experience and in relating it with old experiences. Schema affects humans' perception, encoding, memory recall, etc.
