Answer:
Explanation:
The osmotic gradient in the kidney typically in the medulla is a process that generates urine that is 5 times more concentrated so as to reduce the loss of water from the body.
The countercurrent multiplication is a process that uses energy to produce the osmotic gradient in the kidney, this process facilitates the reabsorption of water from the tubular fluid. This mechanism moves the sodium chloride from the tubular fluid to the interstitial space of the kidneys. The osmotic gradient can be developed in two ways:
1. The single effect: This involves the transport of sodium chloride from the tubular fluid and moved to the ascending limb then finally to the interstitial fluid. As a result of this, the water moves passively down to the concentration gradient out of the tubular fluid than to the descending limb of the interstitial space, until the equilibrium is achieved.
2. Fluid flow method: The tubular fluid enters into the descending limb. This pushes the fluid into high osmolarity typically down the tube. This way the osmotic gradient develops.
Answer:
a guide RNA (gRNA or sgRNA) and a CRISPR-associated endonuclease (Cas protein).
Explanation:
Answer:
The correct answer is D.
Explanation:
Sperm is produced in the seminiferous tubules of the testes, then it travels through the straight tubules and the rete testis and arrives at the <u>epididymis to mature and to be stored.</u>
When ejaculation occurs, sperm leaves the epididymis through the vas deferens and arrives to the ejaculatory duct. Then ejaculatory duct passes through the prostate to merge witch the urethra and finally sperm leaves the body.
Death is the end of life. Dying is the process of approaching death, including the choices and actions involved in that process. The process of death is when someone is dying, their heartbeat and blood circulation slow down. The brain and organs receive less oxygen than they need and so work less well. In the days before death, people often begin to lose control of their breathing. It's common for people to be very calm in the hours before they die.
