Proteins destined for the following locations are sorted in the trans-Golgi:
taurus [48]

Answer:

A

Explanation:

Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.

In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.

Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).

I attached the right answers, maybe some words were difficult to understand:
Vagina in the sex of the female
The urethra is a duct which is shared between the urinary system and the testis. It is located into the penis (it passes both sperms and urine)
Testis means the testicles, where spermatozoids are produced.
Fallopian tube, join between the ovary and the uterus of the female, it looks like an elephant trunk
<span>Vas deferens: are the ducts between the testis and the prostate, it transports the spermatozoid and will be mixed with the prostatic secretion (sperm).</span>

The first insects to be attracted to a corpse are the _____. blowfly maggots blowfly larvae blowfly pupae blowfly adults looking
Alla [95]

Answer:

Blowfly adults looking for a place to lay their eggs

Explanation:

Blowfly adults are attracted to the gases and fluids of a dead body and usually lay their eggs on a dead body within the first two days after death.

The eggs then turn into larvae then enter pupal stages and then become adults themselves. Forensic entomologists can determine how long a body has been dead by the stage of development of the blowfly with the ambient temperatures that have been present.
