A chromosomally XY fetus has a completely functional SRY gene and develops fully functional testes that produce both testosteron
ale4655 [162]

Answer:

Neither the Wolffian ducts nor the Mullerian ducts will develop

Explanation:

SRY gene is the gene is located on the Y chromosome and it is responsible for the development of testes.

MIS is Anti-Müllerian hormone which has the role to prevent the development of  Müllerian ducts (they develop into female internal genitalia).

Androgen insensitivity syndrome is a disorder characterized by unfunctional androgen receptors. If androgen receptors are not working properly,  the Wolffian ducts (they develop male internal organs) will not develop.

So, with MIS and withandrogen insensitivity syndrome, this fetus will not develop neither the Wolffian ducts nor the Mullerian ducts.

What benefit does diffusion provide the cell? A. divides the cytoplasm B. carries out meiosis C. produces protein D. carbon diox
Pie
The answer is letter c. produces protein.
<span>Water, ions and molecules requires for cellular processes, can leave and enter cells through a passive process like diffusion. Diffusion is random movement of molecules yet has a net direction to regions of lower concentration in order to reach a balance. Simple passive diffusion takes place when small molecules pass through the lipid bi-layer of  a cell membrane. Depending on carrier proteins, facilitated diffusion is imbedded to allow certain substances to pass through, which may not be able to diffuse through cell membrane.</span>

which statements about oxidative phosphorylation are true? the mechanisms of phosphorylation and oxidation are directly coupled.
arlik [135]

The true statements about oxidative phosphorylation are the mechanisms of phosphorylation and oxidation are directly coupled.

<h3>What is oxidative phosphorylation ?</h3>
  • An electron transfer chain that is fueled by substrate oxidation and connected to ATP generation via an electrochemical transmembrane gradient is known as oxidative phosphorylation (OXPHOS).
  • Cells employ enzymes to oxidize foods in the metabolic process known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate. This happens inside mitochondria in eukaryotes.

Steps in Oxidative Phosphorylation

  • Electron Transport using NADH and FADH2. Near the start of the transport chain, reduced NADH and FADH2 transmit their electrons to molecules. ... the splitting of oxygen into water, proton pumping, electron transport, and ATP synthesis.
