Answer:

The Y chromosome is an accurate indicator of a person's external sex organs.

Explanation:

Since females have two X chromosomes while males have one X and one Y chromosome, if you are aware of the presence of a Y chromosome you can safely assume that a person is a male. Therefore, you can assume what external sex organs a male has.

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>
  • The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
  • Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).
  • It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
  • The AVP gene for it is found on human chromosome 20.
  • Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
  • It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
  • Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.

Why did sumerians need to trade
Zepler [3.9K]
As any other ancient civilization, the Sumerians were traders as well. And they had a few good reasons to do this. 

Because they traded, their trading partners were less likely to attack them, because it would hurt their economy as well. Furthermore, they didn't produce everything they needed and traded those goods with goods which they produced too much of. 

And lastly, through trade they could also get exotic goods which they would have never gotten otherwise.

Novay_Z [31]

Ans.

The first pass effect is defined as a phenomenon of metabolism of drug, in which drug concentration is greatly decreased before reaching the systemic circulation. It represents that fraction of drug lost, at the time of absorption of drug in gut.

Thus, the client is not receiving all the dosage of ingested drug (aspirin) because of the 'first pass effect.'
