5 0

FSH and LH are the main sex hormones in humans called gonadotrophins. They are secreted by the anterior pituitary gland. They act on the gonads; testes in males and ovaries in females.   LH stimulated the production of testosterone by the testes while the hormone stimulates ovulation in females. FHS promotes sperm production in males while it stimulates maturation of ova in female ovaries.

How does the uterus prepare itself to receive a fertilized egg?
frez [133]
The fertilized egg begins a rapid descent to the uterus. The period of rest in the tube appears to be necessary for full development of the fertilized egg and for the uterus to prepare to receive theegg. ... At the end of this transition period, the embryo becomes a mass of very organized cells, called a blastocyst.

Which is false about osmosis and electrolyte balance in the body? when potassium enters cells, then water follows it. water trav
Mariana [72]

Answer: water travels from high to low concentration of the solute

Electrolytes are known to be major components pf body fluid and these electrolytes enter the body through foods. Thus, major regulation of body fluid and electrolyte balance in the body is through the process of osmosis. However, osmosis can be defined as the movement of water through the semipermeable membrane from lower concentration of solute to higher concentration of solute.

How is it possible that over 20 million living organisms on the planet are made up of only 5 types of nucleotide based arranged
almond37 [142]

Answer/Explanation:

The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.

Imagine an organism exists that has only 2 nucleotides (<u><em>this is over 200,000x smaller than even the smallest bacterial genome</em></u>). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.

Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.
